How to weld with flux core wire

[@GaryDusek]

I have been on the teaching side. So well done. Concise to the point, didn’t bore. As a retired Ironworker I think this is precisely what most people are looking for.

[@makingmistakeswithgreg]

Thanks for the kind words and thanks for your time spent building America 😀

[@elgkas9928]

You missed your calling. You should have been a teacher. You have a way of communicating that others could learn from.

[@jasonchuc]

Totally agree, I like how he described and showing the angle of the weld. He is good.

Great instructions, thanks for going through all the different scenarios. At 63 and retired , I’ve bought my first welder. Last welded in high school 45 yrs ago.

[@frogworth1622]

Newb here. Bought myself a older Lincoln 180 and can't wait to molt my hibernation blubber and give it a go. Winter is too long in Canada but gives me time to educate myself and make plans. Been watching a ton of videos and have to say yours are fantastic (I dare say the best one I've seen so far)! Despite it's bad rap, I'm going to do flux core and it will likely meet my needs for the things I want to do and where. Having had a long career fabricating plexi cases where I flame the edges and also plastic welding hdpe tanks, I can really appreciate the detail you went into about the angles, speeds, settings, etc because they all apply for what I do too. Definitely an excellent video and great resource I will refer to. Bonus tip to other Newbs while practising: bang around a bit when you're in the garage, drop a thing or two, swear occasionally. This way the wife doesn't know how much fun you're having. Thank you kind sir for posting.

[@makingmistakeswithgreg]

You’re welcome. Flux core has a bad rap mostly because of poor quality welders and inexperienced people. If you pick a decent wire (since you have a good welder) you will be able to make excellent welds. If you master running simple beads with flux core, that is equal in width/height and consistent start to finish, you will be able to take that knowledge and apply it to other processes. So much of welding is just moving smooth/consistent/at the right speed, which is a skill that can be built up with any welding process. By seeking information and combining that with practice, you will gain skills really fast. Just make sure to not give up when you get frustrated and you will be doing real well 😀

[@frogworth1622]

Thank you. As a beginner do you think it's best to master one technique ie stacking dimes, sawtooth, etc or to practise varying techniques until you get good at all (but takes longer)? Is that answer dependent on the type of welding you would primarily do? eg. vertical instead of flat? Which technique is the most versatile? If you could only do one technique which would you choose?

[@johnnyveretto313]

Excellent teaching! Dad was a self-taught welder . Didn't teach me because he did not want me to be a welder, I just turned 73 and love learning to weld watching your you tube. (hobby only) Love it!!!

[@makingmistakeswithgreg]

Glad you enjoyed the videos and you picked up welding. No matter the age or skill level being able to join two pieces of metal opens doors that few other hobbies/skills do. 😀👍

[@richardreynolds3597]

This series are some of the most concise videos on weld characteristics and what we should be looking for. I have learned quite a bit as a new weekend welder and appreciate your time and patience putting them together - Thank You!

[@makingmistakeswithgreg]

Thanks for the kind words. I am glad it helped you out, that’s why I wanted to make the videos. As long as you practice a bunch you will be surprised at what you can do with simple flux core. The initial learning curve is a bit steep but after that it’s not hard at all. I will be revisiting some flux core with vertical up and overhead welding once I am done with my stick welding videos (probably about 3 weeks). 😀

[@FranciscoMartinez-oh6wx]

You’re an excellent teacher in teaching people how to weld. Thank you for your class.

[@makingmistakeswithgreg]

No problem and thanks for the kind comment 👍

[@Mike-CanAm]

I purchased this welder (Titanium 125) to learn welding, got it on sale a year ago for 140. I watched both of your videos and learned a lot. Very common sense and to the point.

[@makingmistakeswithgreg]

Thanks for the kind comment. The titanium 125 is a great welder, and is a great place to start learning. The funny thing is even if you “upgrade” to a more powerful welder, or one that can do gas shielded MiG, it still pays to keep the titanium 125 around. It’s simply too useful.

[@T3glider]

By far, the best flux core welding video on KZbin!

[@makingmistakeswithgreg]

Thanks 😱. I am hoping it helps people realize what even simple machines can do and gives them the confidence to build some stuff 😀

[@robertblackshear8963]

Lol. You underestimated the titanium 125. I welded a new trailer hitch on a friends heavy duty trailer with mine and surprisingly I could only run it at about half the settings without taking a chance of blow through. These damn things have lots of power with a highly consistent arc. One guy did an amp meter test in his review of these and got a maximum 140 amp reading. Good video man.

[@makingmistakeswithgreg]

I have a video I just shot with it welding 1/4in material and I did a cut and etch. It has no issue with penetration, however it did have some porosity. I am going to do another run on 1/4 with a different wire and I will see if it’s better. For the money it’s a very good welder. Thanks for the kind word too 👍

[@robertblackshear8963]

@@makingmistakeswithgreg Nice man. I'll be looking forward to it.

[@leskorcala4898]

Wow , I am very new to welding and just researching good tutorial videos and I have to say there is so much knowledge and amazing explanation in this video. Thank you so much ! I have project I would love to complete this fall It’s military trailer which I will be turning in to overlanding camping trailer and want to fabricate frame to hold Roof Top Tent it will be total of 600 lbs weight. I wanted to use 2x2” square tubing and 1/8” thickness. Would you recommend to go thicker or 2x2 1/8” would work ? Thanks you again for your time

[@tyrotrainer765]

Hi again Greg - a safety bulletin for the benefit of fellow metalwork newbies. Earlier I was cleaning up a load of steel prior to welding it, using a brand new (cheap) flap wheel. The bloody thing exploded. Don't know why because I wasn't abusing it, I was just cleaning off mill scale with the wheel tilted maybe 10 degrees. Anyway it dug some deep gouges into the safety guard before some of the bits flew about 10 feet away from me towards my work bench and one piece carved a chunk out of the wood. I was wearing safety glasses and when cutting I also wear a spare cheap welding helmet just in case - for those thinking that these disks can't delaminate and disintegrate I can assure you that they can. The expression is "I nearly shat myself!".

[@makingmistakeswithgreg]

Glad to hear you made it out ok 👍. I have never seen a flap disc explode, but I am sure it could happen. Walter abrasives recalled a ton of their flap discs due to a failure in the glue that held the paper in place. If you ground on a hot weld or used the disc hard enough the glue would heat up and fail, causing the disc to blow apart. High RPM grinders would easily throw parts of it around dangerously. The guards do work, I run them on every grinder I own besides my slow speed Milwaukee.

[@tyrotrainer765]

@@makingmistakeswithgreg Another learning experience - don't buy cheap disks, like I did. I bought 2 at a local store for about $2, one was ok but the 2nd broke - I've just checked and neither has a date, or anything, embossed in the metal part, and the cut-off disks (all a 'reputable' Chinese brand) I bought in the city last week expired in 2022. I've never checked before but I certainly will in future!

[@creativewoodworker4300]

Thanks

[@MelindaPlante]

Just bought my first welder. This was really helpful. I cant wait to get out and give welding a try!

[@makingmistakeswithgreg]

Awesome and congrats. Just expect to fail a bunch at first but you will improve. Try to be as smooth and consistent with your movements as possible. Also, don’t get discouraged if you get frustrated, that’s part of the learning curve. Stick with it and you’ll be building stuff in no time. 😀

[@petematthews7303]

Yes, you do like to talk and thank you for that! I find it very easy to listen to you talk about this subject, and I'm glad I found this video on the first day of researching about welding. I thoroughly enjoyed your delivery about these basics of welding. I've been quite unsure about learning to weld, but I am now SUPER excited to give it a try. Thanks!

[@makingmistakeswithgreg]

Thanks for the kind words. I am glad you are excited, it is a fun skill to learn, and very useful. The best advice I can give to you is expect to fail a bunch, and get discouraged a time or two. Just focus on what you can do better and try to change minor things every weld. After a short period of time the worst you will do will be better than your best you can do at the start. A bit more time and the worst you will do is almost perfect. Don’t give up, practice a lot, and it won’t be long before you can actually build stuff which is the best part. Also, I may make certain things look easy. I have more experience though. So don’t compare your work to mine, compare your work to where you were last week. You will progress 😀

[@matthewsalvador9783]

@@makingmistakeswithgregwow that was inspiring to read. So philosophical. Can’t wait to put your teachings into practice. Thank you.

[@melgross]

The reason why it has a bad reputation is that it’s mostly used, on KZbin, by new welders, using very cheap machines, with cheap wire, with no knowledge on how to use it, often learned from guys on channels who themselves don’t really know how to weld (we don’t read no manuals!). It’s thought of as a beginners method. What people don’t seem to know is that heavy fluxcore is used for large structural work.

[@makingmistakeswithgreg]

It definitely is. With a quality wire and a machine with adjustments, flux core can make really good welds. It’s too bad a lot of people wrote it off as a “joke process” when it really has a lot of practical uses at the hobby level (and structural work with a more powerful welder).

[@bobhopman4648]

True, fact is there are far more factory and professional welds done by flux core, stick, or a laser on a machine.

[@zenjon7892]

It's my favorite process for outdoor work

I've done tons of stick but this is my first at flux. All the mistakes you showed I make lol thank you for saving me tons of time figuring this out. now it's off to practice.

[@makingmistakeswithgreg]

Glad to help you out 😀. If you have experience with stick you will find flux core like easy stick welding. Don’t be surprised if you see porosity that you never see with stick. That stick out of the wire is hugely critical and needs to be maintained properly. That is a bit of adjustment over stick but I find the process overall pretty easy. You will find yourself using it a lot for thinner jobs and repairing stuff in odd positions. You can run flux core uphill way easier than stick, especially on 1/8th or thinner material. Anyway welcome and keep practicing 😀🔥

[@jeffmwoods]

Thanks for putting all this together. Really like the way you explain the whole procedure. You are a great addition to the school of you tube. Thankyou.

[@makingmistakeswithgreg]

Thanks for the kind words 😀. Flux core is a lot easier when you know the details that matter, especially stickout distance. A few small things being off makes it hard not to have terrible welds, which is why a lot of people write off flux core welding altogether. Luckily it is a affordable process that can really help people make some cool stuff once you know what you’re doing 😀

[@bjnslc]

It has been several years since I took a welding class. I just got a cheap flux welder and your videos provide an excellent refresher. Time to practice before I tackle a pretty simple project that motivated me to get a welder.

[@makingmistakeswithgreg]

Glad to hear that. Flux core wire is a great process for small projects. Make sure to practice a bunch and get a good wire to make welds that need the most strength. I find Lincoln’s nr211, Hobarts fab shield 21b, or is forges t11 wire to make real clean/solid welds. No need to spend the extra on those wires for practice or simple jobs 😀

You are clear and concise with no BS...I really really like that. Yes you do like to talk but you are giving out valuable info and not just talking to be talking. Well done sir, I appreciate your time and willingness to share your knowledge.

[@makingmistakeswithgreg]

No problem and welcome to the channel. Surprisingly enough the titanium 125 is a great wire welder and is totally capable of welding anything between auto body and 3/16th thick material (1/4 if you push it). The video series I made will really help you understand what you need to do, and get you up to speed. The most important things when learning to weld is to accept the fact you will fail for a while before you get the hang of it, that you need to practice a bunch to get good, and that before you know it you will be putting down good welds 😀. With flux core in particular you need to maintain a drag angle, 5/8th or so stickout from contact tip to molten puddle, and you need to move forward slowly/smoothly. It won’t take long for you to start building stuff 😀

[@makingmistakeswithgreg]

Thanks, glad you liked it 😀. Flux core wire is very useful, so is tig. Tig has a steep learning curve at the start but becomes easier once you train your hands how to move. Flux core wire is actually super easy to learn because it’s far easier to weld out of position and poor fitups than gas shielded mig. Good luck on your skill development journey 😀

[@JRsVsO]

First, I don't know of a machine that welds HF flux core wire well. I also wanted to thank you for explaining what a good voltage and wfs should sound like on flux core. I picked up a newer to the market "Warcking" 150 multi process, multi voltage machine, and I love flux core welding in and out of my garage shop. I'm still on the .035 wire that came with the machine, and so far, it has worked well above its price. I like to run a "C" style weld on my fillet welds, but you showed how a steady stringer can really do the job, so thanks for the lesson.

[@makingmistakeswithgreg]

I am glad you got some useful info out of the video 😀. You can do the C style and be ok, the main benefit to that is it keeps the wire eating away at new metal. When you do stringers like I generally do there is a fine line with how much metal you can put down before you will either lose penetration or start to get porosity. The big thing with flux core is you want to get that weld to flow out/penetration and minimize porosity. The E Or C motions in my testing can give good penetration and help keep porosity to a minimum.

I just picked up Titanium 125 from Harbor, trying to learn how to weld so I can do small jobs on my rig. Im a complete noob but thank you for the video it is very helpful to people like me I learned alot but still need alot of practice.

[@makingmistakeswithgreg]

It takes a ton of practice to get good, I won’t sugar coat it lol. You also have to do a lot of repetitive things that are fun, like run beads on a plate, which is boring. Think of it like learning to write, it’s a lot of repetition and it sucks. Once you learn to write can take it with you everywhere and it’s extremely useful, just like welding. If you focus on trying to be as smooth and consistent as possible you will progress fast, especially because you are seeking knowledge on how to do it. Knowledge will shorten the time it takes to get good by a lot.

[@UttonPhotography]

I really appreciate the “real time” welding speed

[@makingmistakeswithgreg]

Real time welding speed is actually slower than many would think, the trick is to run settings low enough that you don’t burn a hole through while moving slow. The thinner the material is the harder it is to do that, so travel speed must increase to a certain extent depending on thickness and joint. The key is moving slow enough that material is fusing together.

[@QuiDocetDiscit]

Wow...I listened to you for 43 minutes and time went quickly...I must really like welding. I still have not done my first mig weld. Tutorials like yours are prepping and motivating me. Many thanks for posting. I had to laugh that you had to try VERY hard to do a bad weld...I will have no such problem...for now.😐👍

[@makingmistakeswithgreg]

Thanks for the kind words 😀. When you get to a certain point it is hard to put down a bad weld (I still do from time to time lol). Think about it like signing your name, at some point you can get it pretty much perfect every time. Welding also has a lot in common with golf in the sense it’s a stupidly simple concept but in practice it’s deceptively difficult lol. As long as you keep your contact tip to work distance consistent, your travel speed smooth and consistent, and your settings are high enough that a puddle is established that you slowly drag along, you will be good. It just takes some practice and not giving up. You can do it 😀

I have this same welder from Harbor Freight, my first experience with an. Invert welder, I'm really impressed on how well it welds, nicer looking and smoother. Great Video

[@makingmistakeswithgreg]

I bought one of the titanium 125s back when they first came out. I was surprised at how well it welded and how useful it is. I am glad harbor freight marketed it because it gives the average person a ton of capability for very little money. Their titanium stick machine is also really good too.

[@lindenaho]

I appreciate all your knowledge. Still working on sorting out voltage, feed speed, and all the different pieces that works together and how to identify which is off. Might have to watch your video again. Great stuff

[@makingmistakeswithgreg]

Thanks for the kind words 😀. I made a video on what I call heat metal ratio, it can be found here: kzbin.info/www/bejne/qJ7PZoaQd96SnJI . That video should help you a lot. Don’t feel bad if you find voltage and wire feed confusing. In simple terms voltage dictates the width of the weld and how flat it is. Wire feed dictates how much metal you deposit. When you have thicker metal you need bigger welds than thin metal, therefore you need more wire feed. Everything must be in harmony though, if you have high wire feed and low voltage your weld will just be a bead of caulk on plate. If you have high voltage and low wire feed the wire may burn back all the way to the tip. By keeping the ratios close everything will work properly.

[@okiedoak201]

Holy smoke....you are awesome....your teaching style is so smooth and precise...yea...I don't know if you teach or not...but you would be one heck of a teacher....I have my eye set on the titanium 170 mig welder and waiting for HF to do some special Xmas sale...I started with the HF 90 amp welder and what a disappointment that was...I finally gave that unit a toss in the trash... Anyway...thanks for all the video series...and yep...I subscribed..👍

[@makingmistakeswithgreg]

Thanks for the kind words and the comment. Luckily youtube allows me to be a teacher and have my “lessons” reach people all over the world, which is ultimately one of the reasons I recently started the channel. I am involved in a lot of stuff far beyond welding (it’s a small part of what I do) so I will have a ton of interesting content in the future. As far as welders go the 170 seems to be pretty good. I have used the titanium 200 (works real good) and I will be buying the 140 and doing videos on how to mig weld with that coming up. The difference in weld quality with a proper dc output wire welder and the cheaper AC output Chicago electric welders is huge. Not to mention using quality wire vs harbor freights makes a significant reduction in spatter.

[@staffordsanpei7804]

I am retired glazier who was certified in structual welding. Using 232 flux core. You should talk some about stubbing. All in all, great video.

[@Justforfun-ek7et]

Picked up mine for $140 when it was on sale. Pretty nice little flux core welder. I definitely have an addiction problem for welders. Don’t care if they are cheap cause I have 3 of the green harbor freight welders and one AHP I use for TIG. It’s handy to have a machine for each specific process so I don’t have to keep changing settings and electrodes etc… I really appreciate all your videos, very helpful with all your advice.

[@makingmistakeswithgreg]

Glad the videos have helped you 😀. There is nothing wrong with multiple welders, that’s what I prefer too. I have owned two different all in ones (esab rebel 205 and everlast 275) and they worked, but I much prefer stand alone machines. That way the machine can be set the way I want and I use it for that. Not to mention the reliability issue, you never know when one tool may have a issue/fail. I always have a backup, I’ve been burned too many times lol.

[@karljolley8346]

really excellent instruction. Thanks. Vulcan and Lincoln wire are spatter lovers. Forney Yeswire Hynide wires are top of the line, according to last head to head comparison that I saw.

[@makingmistakeswithgreg]

You’re welcome. There are definitely differences in wires. Gasless flux core has to be the worst when it comes to specifications. I have been doing some testing on 3/8th plates and having issues (not too unexpected). To help better understand what’s going on I looked into the spec sheets for every manufactures Gasless flux core wire I could find locally. Every manufacture specifies different max plate thickness for their wires, different test results, and literally different operating voltages/wfs settings. I think the key take away is that you need to find a wire that is suitable for what you’re doing (and is multi pass rated if doing multi pass) and that runs good with your machine. Unlike with gas shielded Mig or even stick, switching wires to another brand with flux core is almost guaranteed to cause issues.

[@karljolley8346]

100% agree. I found a reasonable priced brand at my welding supply that reduced my spatter by half. obviously more suitable to my "garage welding". You gave me the answer to all of my welding issues: speed, stick out, settings. in that order. @@makingmistakeswithgreg

@@karljolley8346 I am glad the info helped😀. I am sure you saw a drastic difference in how your welds were looking after a few tweaks in what you were doing. Flux core is a great process but it works terribly if something as simple as the wrong stickout is used. Once you realize the “range” you need to be at for everything it works great and gives a ton of capability.

You won’t regret it, they can help you build a lot. Just take the time to practice to get it dialed in. Your first welds won’t be the best but it won’t take long to get much better. On a interesting note Lincoln electric is actually going to be releasing the welder under their own name shortly lol. They will have it as both flux core only and mig/flux (aka gas capability). No idea on pricing but obviously more than harbor freight lol.

[@johngersna3263]

Greg, after 40 years I finally found out that my old Century built Powermate Quick Fix was junk. 🤣😂 I got the gas conversion and only used it on sheet metal. It was the best mig that I could afford at the time. Fast forward to today and I'm going to get a new welder in the next few weeks. I've settled on a Hobart Handler 210 MVP. I believe that it will do everything that I will need. I'll be working on some sheet metal on my "63" Falcon. I would really love to have a Miller but unfortunately that's out of my price range. But that being said, Hobart is made by Miller. Anyway, what I wanted to say is that I learn something from every video that you make. Again, thank you and God bless.

[@makingmistakeswithgreg]

Thanks for the kind comments. The 210 mvp is good from what I have heard. Hobart is owned by miller, and the build quality and parts generally reflect that. Millers prices on a lot of machines are sky high (and unreasonable in some respects, like there 140amp MiG welder at over 1k). The difference a good MiG welder can make is huge on the low end. Welding sheet metal and thin material tends to be far easier with .025 wire and a quality welder with good low end capability. I will be dabbing into MiG shortly, I just need to finish up stick welding videos. 😀

I recently picked up a welder after 30 years. I'm trying to weld 14 gauge square tubing that's rusted and pitted. I think what you are trying to show people when it's done wrong is what mine looks like 😖. This was very informative and I'm probably be checking back with this video time and time again as I try to get my bearings with this titanium 140 harbor freight welder. Having a real bad problem blowing holes through. When I'm not doing that it's not getting penetration

[@makingmistakeswithgreg]

Flux core tends to have a bit more penetration than short circuit mig, so no doubt it can be a bit challenging to weld thin material. Here are some tips to help out getting the best results. Make sure you are using .030 wire. Make sure the gaps are minimal/fitup is tight. If you tend to blow holes soon after starting try to lower the wire feed a pinch. If it still blows holes run little 1/4inch welds then stop right before it melts through. Ideally you would run a complete weld start to finish, but sometimes it’s very difficult to do. Doing short welds will be weaker, but on thin material it probably won’t matter. Find a setting that works to run a simple bead on the material that looks decent and doesn’t blow holes. That should be a bit on the cold side for an actual weld between two pieces but if there is a gap it should buy you some time before a hole shows up. Beyond that it comes down to a bit of practice. The thinner material the harder it is without a doubt.

Thanks 😀. Rockers are doable with the machine. Generally gas shielded MiG is preferred, mostly because at super low values porosity isn’t a issue. However with some fine tuning you will be able to do it with flux core. Definitely practice on the same thickness material as much as possible before trying it. It also helps to have someone hold a piece of copper on the backside of the welded are (or holes you need to fill) to prevent a blow out). Search copper auto body spoon to find cheap ones on Amazon. I will do a auto body video soon that will be of use 😀

NIce job. I was surprised to see you welding from right to left as a right hander. I usually like to observe the puddle just behind the arc with the tip angled away from view where you are viewing just ahead of the arc. I found if I slowly move side to side for the first half inch or so of my welds that I get better penetration into both sides while the metal is warming up.

[@makingmistakeswithgreg]

So I don’t really know why, but with flux core I weld right to left about 50% of the time. With stick it’s 90% left to right. Mig is right to left as well most of the time. Bizarre lol. Great tip on the starts 👍

[@marcbrazzers]

When you say "lower your settings" .. can you please elaborate? My mastercraft mid/flux core welder 110v (using no gas only flux) burns through often and all i have is a button that says "Voltage" as "min" or "Max", and then "Tension" as "1" or "2" and then a dial where I can select wire speed from 1 to 10 as an adjustment. Thanks for the help!

[@makingmistakeswithgreg]

Ok so I looked up that welder your referencing. Unlike the welder in this video, you don’t have adjustable voltage (well more limited voltage control). More than likely you have 4 voltages to choose from: low 1 and 2, and high 1 and 2. On a welder with more control, you set wire feed to produce a appropriate weld size for the material you’re welding on, and set voltage to “wet” the weld out. Since you have fixed voltages you need to set things a bit differently. You need to start off by measuring your material thickness and setting your welder to the chart it came with for that thickness. If you don’t have a chart then set the machine at 3 or 4 for wire feed speed and low 2 for voltage (if the material is fairly thin. You need to run a short weld, about 3/4in or 1 cm and stop. If the weld burns through the material and you were going at a steady pace, drop the wire feed 1 notch and try again. If you are near the bottom Of the settings and still burning through either you’re moving too slow or your machine isn’t capable of welding that thin of material. Keep in mind if you are learning to weld, it’s best to start with thicker material. Trying to weld thin material is going to cause immense frustration because you have not developed the hand coordination or the understanding of what to do to not burn a hole. A skilled welder can control burn through simply by watching the puddle, and speeding up as needed to avoid melt through. That skill just takes some time to develop. Some welders simply cannot be easily used to weld thin material. .030 flux core wire can easily weld 1/16th thick material (1.6mm) to maybe 1mm. Below that .024 MiG wire and Gas shielding performs far better. However again your controls are more limited and likely won’t run that wire well. So my suggestion is practice on thicker steel than what you’re on, and once you can weld solid beads consistently, then drop in thickness. It is possible to start on thin material. You must have a very high tolerance for failure though, and frustration.

I bought a small 110v flux core machine once , and even if im an 20+ years experienced mig welder , i found it really hard to weld with this. Maybe a hobbyist would find it easier but for me , the problem was that it didn't feed well. Im used to quality machines that feed consistently ( i work with an esab warrior 500i ) and the inconsistent feeding was way off for me. I can't do a nice weld with that whatever i do

[@makingmistakeswithgreg]

Feeding is better on higher end machines no doubt, however if decent wire is used (Lincoln nr-211 or fabshield 21b) and the tension is adjusted decently the little titanium 125 can make some really decent welds. Self shielded Flux core in general isn’t the best process for the best welds, it’s highly sensitive to changes in feed rate so you are right, beyond a certain point you’re limited.

[@Saleen35000]

​@@makingmistakeswithgregi ended up selling it , welding way too cold to my liking. Usually i weld with solid .035 wire , 1/8 thick i set it to 25volt and 500 ipm so im not used to this cold weld. But at least i did what i had to do before selling it. Might try a better quality machine one day. I do a lot of dual shield too so for me , flux core welding is more a hobbyist thing ( at work we have .045 flux core wire too but the spools are just taking dust in a corner we barely use it )

[@makingmistakeswithgreg]

Great question. If you knock it off fast the bead will turn dull grey or blue color as it reacts with oxygen in the air. I would wait until it’s cooled off enough that nothing is clearly glowing red. It will make a shinier weld and be less likely to have molten hot slag wind up on you causing burns lol. Flux core wire (self shielded) is more or less powdery and easy to clean without big hot chunks. Many stick rods produce slag peels that can really burn you if they fall on your pants or something lol.

Great video. Just bought a Arccaptain 200. I am a totally newbie and all my welds looks like s…. I wish your welder didn’t use ABC etc but amps. Maybe more understandable for a newbie. I am only on my first flux roll so I guess I have a long way to go. But I did learn ;)

[@HelleMarkussen-nj7ey]

Spend the afternoon making huge mistakes. Trying to weld 0’9 and 1,5 mm steel. At low settings I managed to blow holes in the 0,9mm. Do you have a video where you show/explain setting in WF and amps? I wish I had someone like you next to me *lol*

[@makingmistakeswithgreg]

So I have a bunch of advice that should help you. I have not used the arc captain 200. If it has the ability to adjust wire speed and voltage separate that will be good. In a nutshell wire feed is how big of a weld you want to deposit. Thin metal needs small welds, so you need low WFS. Thick metal needs big welds, so you need more wire. Voltage determines how wide the weld is as well as how well the toes of the weld “wet out”. If the weld sits on the plate like caulk, it needs more voltage. If it’s excessively flat and undercut is present, less voltage should be tried. The limitation of wire welding is that many 200amp class machines can’t handle big wire (.045+) or very high wire feed speeds with .035. So their ability to weld thick steel is limited. Because the wire size controls the amp handling capability, and a lack of overall amperage means lack of root fusion, the ability for a 200amp welder to properly fuse 3/8th+ plate becomes limited. Dropping from say .035 to .030 wire won’t improve root fusion despite being able to push the smaller wire hotter, because the wire will tend to “blow apart” creating excessive spatter before it fuses the root. Video wise this particular video should help explain the balance of WFS to voltage a lot better: kzbin.info/www/bejne/qJ7PZoaQd96SnJIsi=D_QLczLxH5mcbMFg

[@stevewheatley243]

Excellent video. I would've like to see some stress testing though. To see how much those welds would take.

[@makingmistakeswithgreg]

I have done a few flux core weld tests. One of the big issues with flux core is in .035 wire it seems to be incapable of welding 1/4in without some pindots of porosity. Steel thicker than that (5/16, 3/8th) will have a lot of internal weld porosity with .035. Stepping up to .045 flux core solves most of this (the issue is the weld pool cools too fast and the escaping gas can’t fully escape with .035 on thicker plate). Because of the porosity issues with flux core it tends to perform far less than short circuit mig on bend tests. In this video you can see what I mean: kzbin.info/www/bejne/onbcpYqHhrV7hbcsi=7TewILNGprFooqUg Also, standard store bought flux core wire seems to produce a strong but brittle weld. It doesn’t have much give between its yield strength and its ultimate strength. There are a ton of flux core wires that perform far better than standard store bought wire, but unfortunately they commonly are only available in .045+ diameter and require a lot of amperage to run. This makes them impractical for the average person to use (most home machines can’t run that diameter or handle the voltage/amperage of bigger wires. They are also only available in big expensive spools.

Can I use a wire wheel to efficiently knock off slag? I left a ton of slag at work that I need to take care of in the AM. I have a bur motor but I destroy my welds with it

[@makingmistakeswithgreg]

A wire wheel will do a good job with the slag on gasless flux core. It’s more powdery and loosely attached than say a 6010 stick rod pass. The only thing you have to watch for is the toes of the weld, they tend to collect thin lines of slag. If you multi pass over them on a x-rayed weld you may bust for what appears to be “wagon wheel” tracks, aka thin lines of slag entrapment. The wheel will take care of 99% of it though, if you have it use a un-knotted wire wheel so it gets into everything well 👍

[@anderslawncare5111]

Hi, really enjoyed this video. I have a yeswelder with Amp Setting. WFS and volts are set by machine automatically. But you can also fine tune Volts from -5V to +5V. What setting do you recommend for 1/8” plate?

[@makingmistakeswithgreg]

So the yes welder uses a different approach for control than the welder in the video. Since I don’t have a yes welder it’s hard to say what setting to use. What I would do is use the recommended settings for 1/8th than they say to, and then base the voltage adjustment on what your weld looks like. If it’s roped up and not “wetted out” go up in voltage. If it’s real flat and overly hot lower the voltage a bit.

[@makingmistakeswithgreg]

Thanks for the kind comment. So unfortunately the machine can’t weld aluminum because the flux core process was not designed for that. You can wire weld aluminum with the gas shielded MiG process (argon shielding gas and what’s known as a spool gun or push pull gun). If you want to weld aluminum there are very few options that are available under 6-700$ and that would be for the MIG process with a spool gun. The titanium flux 125 can weld steel and stainless with flux core wire though.
