Flux core welding tips, why change polarity?

[@ingwiefreak]

Finally, someone who explains it properly so you understand it! THANKYOU

[@wallacematthew8512]

i guess im asking the wrong place but does any of you know of a tool to get back into an instagram account..? I was dumb lost the password. I would appreciate any assistance you can offer me.

[@eddiejairo1459]

@Wallace Matthew instablaster ;)

[@wallacematthew8512]

@Eddie Jairo I really appreciate your reply. I found the site thru google and im waiting for the hacking stuff now. Looks like it's gonna take quite some time so I will get back to you later with my results.

[@wallacematthew8512]

@Eddie Jairo It did the trick and I actually got access to my account again. I am so happy! Thank you so much you really help me out!

[@eddiejairo1459]

@Wallace Matthew glad I could help :)

[@Dr.Stein99]

Hi, thanks for the video. This explains it. I appreciate you getting down to business and me not having to skip through 20 minute tour of your garage, house and details about all your pets and gadgets and tools.

[@richard506rb]

I second that.

[@stevenrolfe1918]

You have just saved me chucking away my MIG .. I have always used shielding gas and yesterday I tried flux core, it was a disaster! Exactly like your first demo.. thank goodness I now know why .. very clear advice.. thanks a lot!!

[@cri8tor]

After all these years, still the best explanation of why we weld electrode negative with flux core welders. Cheers m8

[@shadow7423]

Bloody hell! Here I am struggling to learn to have better welds and always made a mess with splatter everywhere. Struggled to find the right setting so there were minimal splatter. Sometimes it’s either too high and would burn the wire to the tip or burn a hole. I never even researched or read anything about the polarity change. I just assumed that all mig welders had the same polarity with a gas setup. I am just learning to weld and I need a ton of practice. But I’m sure after knowing that gas and gas less setup have different polarity, I’ll be more determined to give it another go. It was discouraging when I look at my crappy weld, it’s one of the worst anyone would ever see! Not having the right setup doesn’t help either. THANK YOU for the video!

[@ritchiedusch2351]

I got a flux-core welder as a gift a couple years ago and was very disappointed with the amount of splatter. After viewing this video I reversed the polarity and was very happy with the results. Reversing was not easy. I had to un-crimp the leads and re-crimp, but it was well worth the effort. I had given up using this welder because of the splatter, but now I can weld the thin stock that had been so difficult with a stick. Thanks for a clear explanation with a great demo.

[@on2you]

At least you described why its needed. The first time someone explained it thank you

[@louisdilloway6366]

You have just solved 99% of my problems. Thanks brother!

[@WannaBFree]

This is the best video I've seen on this subject. Thank you!

[@josephsmithe5774]

I want to start using flux core with my everlast welder. Thank you for the very clear explanation on everything.

[@myharris]

Mystery solved. Clear, concise, to the point. Bless and save ya.

[@cri8tor]

Recently posted a video on modifying my Flux Core welder and didn't have an explanation for why your ground clamp should be DC positive, but now I do. Cheers m8

[@DomXereX]

Thanks a lot for the explanatory and practical presentation because it helped me a lot. I'm an amateur and I usually do welding only as needed to fix something or make a little thing I can't buy. After changing the polarity, welding goes much better and looks much nicer. Thanks again! God bless you!

[@jb-ik8sj]

good point. us rookies need pointers like this from time to time. I'm gonna change mine now thanks

[@bmerfunitec]

Thanks for taking the time and effort to show this and explain the polarity adjustment in the comment discussions below.

[@minouchat]

Nothing better than a video to see the comparison ! Thanks. Have a nice day !

[@SoilentGr33n]

You're the only guy in all texts and videos that I have seen that makes it OBVIOUS that when we are talking about reverse polarity, the GUN IS - AND THE CLAMP IS +. Thanks for the CLARITY

[@jimc5439]

Excellent explanation and video on polarity, clear, simply and right to the point.

[@criticalreasoning2129]

Wow, great demostration! Thank you sir. I just wish you had mentioned to use knurled wire drive wheels with soft crush-able flux core wire. When changing from gas to gasless you need to change the drive wheel and the polarity. Flux core needs Negative Electrode and Knurled Drive Wheel.

[@patiencepeeler7103]

Thank you for the tip I'm a new hobby welder and this really helped answer my problem with my little 110vlt flux core welds spatter

[@6lr6ak6]

Good video, l just bought a flux core 130A set brand new £80, after only ever using stick, arc, MMA welders since early 80s as l was a coded welder, but this set really is OK, 0.8 wire, get very good welds, but for the people buying for car body work your better with a gas mig set as these flux cored will blow holes in the plate, but for general welding there great.

[@UKpolitoons]

probably the most useful video ever for home welders THANK YOU!!!!!!!!!!!!!!!!!!

[@legalsolutions07]

Excellent video. First I've seen that gives a clear explanation between AC & DC and a nice example.

[@jamesharrell4360]

Unfortunately he only did DCRP and DCSP. Didn't do any AC to compare all three.

[@marvingoodman3613]

I like your videos the way you talk about welding technology instead of just bragging on some experiencive welder

[@JRo250]

Thank you for explaining this so clearly. A picture, err, video is worth 1000 words.

[@stephendavies6506]

i made this mistake and this vid showed me why i was getting too much spatter. thanks.

[@stephenfestus9268]

Great video...That's one of the best explanations / demonstrations that I've seen

[@mrskafloc4063]

Nice work I have a small Stanley welder don't know if it's possible to change polarity. Will look tomorrow.

[@JackOfAllTrades2022]

I’ve welded most of my working years, and a mig using gas is the best way to go, save your money and buy a mig welder with the gas tank. No splatter at all and great welds. A tig welder is also a great way to go , I should do more videos on welding with a tig welder.

[@paulzytsel3557]

GAS IS NO GOOD OUT ON SITE ON A WINDY DAY THOUGH.

[@fredwilliam1574]

First time I ever welded with flux core with my everlast welder was getting the polarity wrong. I'll never make that mistake again. It took me a long time to figure out what was going on.

[@Yogurtmeat]

This could potentially confuse people who are not trained professional welders... Always refer to the parameter guidelines for which polarity is to be used. Generally the polarity depends on whether you are using a shielding gas in conjunction with the wire... FCAW self shield/ FCAW Dual shielded.

[@Mike75575]

Why do manufacturers send fluxcore machines out rigged "earth negative" ? When "earth positive" is the way to go ? Thanks PS great videos👍

[@eltonmartin5623]

Yes I’ve been looking for a video for the explanation for why you you should switch the pluralities with positive and negative connections! Thanks just got a question for you. Can I do this with any brand or voltage mig welder? Cause the welder I have does not make it easy to access. Looks like I need to take cover off all 8 or so screws. This welder is old and company out of business.. thanks again for your help great vid 🧨🔌

[@Chilllybob]

I have a question first time welding I use forney flux core wire .30 which says polarity is DCEN.. I really like that wire it worked great I ran out and where I got it from they didn't have anymore so I purchased inweld flux core .30 at Fazzios but this one says polarity is DCEP........ Also for regular wire it says DCEP .. I think this company mislabeled the description. I highly doubt both solid wire and flux core wire run on the same polarity. Anyway do I still run this wire on DCEN I was experimenting today this wire which sucks by the way it leaves a lot of slag and a lot of powder. It leaves a mess unlike fortney wire... My question is should all flux core wire regardless of the instructions be run on DCEN..

[@leonardmcdermott7703]

Good video now my question, is it possible for me to change the polarity on a Lidl welder?

[@marekwieckowski7038]

Thank you for explaining it Sir.

[@chico280]

Thanks, I couldn't remember which way the polarity went.

[@lemat3219]

Hey, thank you for a solid effort, your clear thinking and explaining simply work. I have a "hacky" question; could i change the polarity and install a spool gun - on a flux core welder to make it work as a mig aluminium welder?

[@PanjiArasma]

may i know what wire you use?

[@JanisALocmelis]

Best explanation ever . Thank you SIR

[@CainSample]

I finally understand it...best video ive ever seen thank you!👍👍

[@johnshelley2919]

Hats off to your sir!! Thanks a million for the what and why explanation

[@theflatlander123]

you were straight to the point and I like it.. thank you

[@woodshome11]

Right to the point, well done sir.

[@wrigleydimma6856]

spot on nearly took welder back works fine now )

[@GeneGladden]

Well taught brother.

[@gregorydahl]

Thanks . I hope youre right . I got a new inverter welder with 4 functions mig , mag , mma stick , tig . The mig and mag are to do with the inert metal or gases . The google is hundreds of contradicting stories . My instructions only said mag was negative electrode no gas . But i have a lot of spatter and cannot see the puddle . Only see the arc . I can switch easy enough . So i think of it as a lightenig gun . Zap zap negative to remember Thank you again

[@BenSonOfJohn]

Thank you for a super simple explanation.

[@1700iDiGuy]

What brand of flux core wire do you use, prefer? I know there are a lot of cheap stuff out there, a lot of which isn't great. I use a Flux core mig using SiF MIG flux core wire.

[@maritahartmann591]

love the accent... this question was on my midterm... google is wrong about this.... thanks!!

[@gavinrichardson3918]

Other than the splatter does it compromise the weld or anything?

[@reg428]

Thanks. Expertly explained.

[@carandboatnut2]

I think that was an excellent demonstration thank you

[@AussieAnnihilation]

How do you reverse the polarity? Ive got a welder a while back but all the splatter put me off using it more.

[@anthonyguy1347]

I have a Jegs Mig 100 flux core welder. I opened it up, and everything is hardwired. So I didn't change the polarity, because I was afraid of vouding the warranty. The machine makes terrible spatter, but I don't know anyway to change the polarity without butchering the machine. Any suggestions?

[@keithrobinson5594]

Good info clear and concise. Many thanks

[@Sarfarazkhan-ij6dx]

What about mig welding polarity is electro positive or negative please tell me thanks?

[@CrippyCream45]

I have a 130 welder flux cored. I can’t change the polarity because I can’t find the neg pos connections in my unit. Does my welder not give me the option?

[@raykim1812]

In self-shielded FCAW DCEN is right. But Using shielding gas the polarity of FCAW have to be DCEP.

[@JackOfAllTrades2022]

So do you keep it AC? I’ve seen many people convert to DC negative, is that necessary? I can just flip the wires?

[@Joseph-Colin-EXP]

Does this go for dual shield too?

[@thankfullife7968]

Thank you for the simple explanation

[@Hiker63]

Thank you!

[@AGwheelsports]

Short and irrefutable, thanks for this video, I´m going to change my welder now

[@titan371]

Nice video. One question you only use the electro negative if no gas is in use ??

[@johnmacmillan627]

Thx. Just the explanation I was looking for

[@DiHandley]

Bloody brilliant. Well explained. Cheers.

[@meh6953]

Thank you so much!! For this informative video.

[@DaddySeebran]

Will it damage Machine

[@supergoat3385]

polarity depends on the wire being used, I think there is a chart for that.

[@backstreetmechanic]

To be totally honest, I don't use a branded flux core wire. I was more interested in the diameter. it is more common in .9mm diameter. I wanted a .8mm wire, so as not to have yet another tip size

[@maximelavoie8936]

good tips!!!! but you should still use a cup, the spatter could come up and block you're gas outlets and all that good stuff!!!

[@timothyarnold777]

Flux core doesn't use gas, that's why he didn't use or need the shield.

[@fromthebackofmymind]

Plastic tip to protect the copper nozzle. They sell them online. Pack of two $9.

[@detroiterish]

Very helpful and well presented.

[@johnprice1105]

my machine came as a gasless machine to start with can i still just swap polarity its a sealy mighty mig 100 with no setting on any of the panels just paper work to put it together, I'm a novice so need all the help i can get lol, cheers

[@christopherkanuk2546]

Thank you Very much needed information

[@94f1senna]

I've checked my Mig welder and although it's gas and gas less there is no where to change clamp lead to positive ,I've opened Mig welder completely up inside and no negative or positive terminals. My Mig is an old taskmaster 130 gas and gasless ,

[@danburch9989]

There's limited info on your welder on the internet. But it appears that your welder is gas only. DC- is for gasless FCAW. Since yours is DC+ only, you need gas to weld steel, stainless steel and aluminum. Being old, it may have been built in the days before they understood the differences in welding results between DC+ and DC-.

[@scottlytton5328]

But how did you change polarity????

[@mileswatkins6472]

What happems if you weld a mig welder with solid wire and no gas ?

[@goatsinker347]

Why is it electrode positive with stick welding? It is still a flux based welding process.....

[@Rusiputki]

Ma nigga backstreetmechanic showing 2 tutorials in 1! Notice how he isn't using those super rare plastic shrouds / mig tips designed for flux core but simply removed the regular metal shroud and just welding with the 0.8mm tip as it is giving him much better visibility. From all the welding vids on jewtube this is the guy to watch.

[@agguilarmetalwork4494]

Only for flux ?

[@warlocquegander3080]

Excellent, thank you!

[@lilinstig8r]

This just saved my @ss and a trip to the hardware store to subsequently make me look like an idiot! Thank you!

[@mainormurillo7254]

I have a 90amp ¨PowerBuild¨ flux welding machine and I have try to switch the polarity on it but when I opened up I realized it was can of warm so I put it back together and did nos mess with it. I am still welding like dog shit wasting my flux cord, I wonder if someone has the same Brand that I do.

[@Mr1Schoolmaster]

thank you sir ...to the point. the way it should be.

[@TrueBlueEG8]

Where in Dublin are you from man?

[@kundrew1990]

Great vid thank you makes sense.

[@chapmaker46]

great vid thanks

[@mccoy786]

maby camera angle but the first weld looks better,looks like no porosity and more uniform than the second weld

[@ifell3]

I agree

[@ozzstars_cars]

Same thing I was thinking

[@bradg8814]

Me too

[@ImNewbeh]

Why don't you have another piece of metal over the tip of your gun ? (I'm new to welding)

[@jamesharrell4360]

It's more of a dielectric shielding to prevent noobs from accidentally contacting the "gun" to the workpiece. It's really only necessary for MIG because it contains the shielding gas. On your average harbor freight, northern tools, or tractor supply "AC Flux Core Welder" it will come with a shield or two of two sizes... Just throw them away unless you plan on letting your kids or best friend play with it.

[@ImNewbeh]

@@jamesharrell4360 Ok thank you :P

[@jasonmeade2019]

Good video

[@robertblackshear8963]

The second weld is actually better with more visible penetration and appears hotter. But the first weld is more uniform. Still a good demonstration.

[@devonm5037]

dcep is what I weld with but I've never seen that amount of spatter.

[@danburch9989]

If you use gas, you use DC+. Gasless FCAW uses DC-

[@BeeRanDyn]

If you run a thicker diameter flux-cored electrode wire you can switch the polarity to DCEP.

[@TruckThisGarage]

Why does the first weld look better.

[@alejandrocasas1455]

And what happens if is not flux core (gas shield) and switch polarity?

[@eltonmartin5623]

Alejandro Casas just reverse the welds in video.

[@xTrollz0r]

Why does the Electrode + weld look better then the Electrode - ?

[@infertilepiggy5667]

why would you ever put it on the other way??

[@TheNoobComment]

I don't get it. So, that means, just lower the tip more? How can I change positive to negative? So confused...Just got a 90v from harbor frieght and my welding splattering sucks!

[@james4wd236]

inside the machine next to the wire there should be two knobs positive and negative, you take the eyelits off and switch them to reverse polarity

[@eldongarner5375]

+TheNoobComment Harbor Freight 90 amp welders are only AC there is no ability to switch polarity, their 170 amp welders can be changed. For Flu core wire. But you can get good welds with 90 amp machines. Keep your material thickness down to 1/8" .

[@jeffery19677]

DCEP and turn the wire speed down or the voltage up. Unless the wire is SPECIFICALLY for DCEN, do NOT switch polarity. If you weld on anything that peoples lives might depend on, do NOT use Electrode Negative. I weld on powerplants and steam pipe for a living.

[@eltonmartin5623]

Jeff Benefield good point but all your doing is making the piece hot and your gun the ground! As long as you keep working area clean and safe.. give ‘er 🔌🔌🔌
