Tech Tips: Self-Shielded Flux Cored Arc Welding (FCAW-S) Troubleshooting

[@paulinmt2185]

Your "incorrect" examples look better than my typical welds. Oy! Thanks for all the vids. I learn a little from each one.

[@mikemccaffrey3093]

Just finished welding an exhaust pipe to flange. This video really helped me figure out what to look for. I was running too high a wire feed. My first trials were terrible. Almost gave up. This video helped a lot. My next weld was much better but still not very good. The welder feed was hanging up and poor arc. I put a new contact tip on and wrapped copper wire around the cheap sheet metal ground clamp. Much better!! This video made the difference. Thanks!

[@green-zone36]

I have been messing around with flux core for 20 years. I can do a decent job sticking things together. BUT I have never had the slag come off the weld like that. I need to do some more adjusting to get this result. Impressive. Now I need to get out there and make it happen. Well at least try to get there!!

[@jnhook8086]

Glad I found this video. I wasted time watching several different videos and you sir just compiled the info of all of those videos into one. Thank you

[@anonymousnobody7640]

Great job! Brief, clear, informative, helpful.I am doing FCAW-S for 7 years and, I hope, able to appreciate this video.

[@TyphoonVstrom]

I do a lot of flux core wire welding, the video tells you all you need to know. The principles of ALL welding are the same, control the weld puddle. In that respect, it is identical to gas MIG and electrode welding. Every technique you would use for electrode or MIG welding applies to flux cored wire. What no one seems to mention is that you need to change wire sizes just as you would change rod sizes electrode welding, although MIG is far more accommodating of wire that is a little too large or small. Having said that, I use 0.9mm wire for everything form vehicle sheet metal to around 1/4" and the flexibility of the flux cored wire is excellent in this respect.

[@ak47law]

+Sideslip Very good info, thanks for the input.

[@Majorvideonut2]

I see the light but can't see the puddle. It's like welding looking at a flash light. How do you get past the light to see the puddle?

[@pantelissaliaris5398]

Barry Wind darken your mask 😉

[@Majorvideonut2]

That was my problem... the mask was too dark. It was so dark I couldn't see the puddle or the metal edge I was trying to weld. I did lighten it and there it was... my first view of a molten puddle. I was afraid to lighten it thinking it would hurt my eyes... but I took a chance. I had it set at 10 which everyone says is the magic number, but not for my helmet.

[@rl2769]

Barry Wind I stick and mig with my hood set on 9 (Lincoln hood)

[@bf2823]

An excellent, helpful video. One observation and suggestion: It is well and good to demonstrate "too slow" and "too fast" (etc.), but what about "just right"? I suggest that the short clip around 12:00 be edited into the beginning of the video (as well as at the end) to show what a good weld bead looks like before showing the several possible errors.

[@DavidTheCarpenter]

I just went and practiced all the wrong stuff. The only thing I did that you didn't was melting the .030 tip. I hooked up to correct polarity and looked at the box to make sure. Then I looked and read it 2 more times and switched the feeder to positive. Practice was 1/8 x 1 1/4 L, well cleaned. It was horrible and I remembered it doing so well the last time I had it out. It seems that the machines problem may be my glasses. Thanks for this video, I watch it every time I am outside failing at this. Farm welding is what my aspiration is.There are a lot of tractors and implements in my world to maintain. Almost not too bad is my self graded work with 1/8" 6011 and 7018 rods on around 80 - 125 AC amps. That machine and my tanks are too much to haul around off the farms. Hence a 110 dc/140 amp inverter MP, two new 20 breakers, 12/3 wire and 20 lbs of FCAW wire. Good thing that's practice wire... lol

[@samvimes1083]

Just picked up a mig-pak 140. Never tried fcaw before so this is all pretty new to me. On the plus side I'm the only let down in the operation, the welder has fed flawlessly.

[@ozzstars_cars]

[@angelonicassio7131]

Every one of your "Terrible" welds is better than anything I've been able to strike. I didn't splurge for a Lincoln but really, I have addressed all these variables except polarity. I don't think my machine can be changed. Ill look into this.

[@citec123x]

Excellent tutorial, without going around the bush but straight to the point...GREAT !! I just bought a BOSSWELD-M100 and with probably an hour worth of practice under my belt.....

[@guntotinmedic]

Jesus, I suck so bad your worst weld looks better than the best one I have done yet and have ran half of a four inch spool of wire through it.

[@Majorvideonut2]

[@richardclark9204]

Barry Wind not saying I'm any better but stay with it! Somewhere around 300$ in gas and about 25 or 30 # of flux core in it seemed like something clicked, just started " feeling" it, and suddenly l sucked a lot less!

[@atcaleb]

for me it was a cheap helmet not letting me see what I was doing. I had the mask on a stick helmet that came with the welder. Once I got a decent view of what I was doing and was able to weld with 2 hands I have really come to enjoy welding and found it a very useful skill.

[@Majorvideonut2]

I tried turning the shade down to 10 like one on youtube suggested and it seemed to help. I'm better but not great. I don't know what I would do without the welder now. It has really opened up ways to fix problems that I couldn't have without it. : )

Can you please help me. Where can I get the speed and Voltage settings for the NR-211 MP Wire for my Lincoln SpeedTec 200

[@withoutdad7616]

Great job, I noticed you said you wanted to feedback to improve. Try a video with 2 variables gone wrong instead of one, like too high voltage with perfect, short, and long stickout. Then do too low of a voltage with the same stickout criteria. Plus, use pictures in your videos that you pause on, showing side by side comparisons of labeling the two variables conditions for what you chose in for each variable. And last show in that image the perfect conditions. Hope this helps you and if want to send me a free welder or welding equipment for this quality feedback let me know.

[@leonardpearlman4017]

It's probably common to have two or three things wrong at once! Might make for a long video if you tried to work all the changes! (say, wire speed LOW, and travel HIGH, then wire speed HIGH and travel LOW). That's a great suggestion, but it might take a series of videos to implement. Ah, sometimes people who weld for a living are not good at diagnosing things and changing the setup, I think in factories there's someone who sets everything up for everyone? I have got paid a few times to just look over something and see why it isn't working, or maybe even talk about it on the phone! You wouldn't believe it, but people do things like getting the wrong gas bottle, and everything goes to hell and they just can't imagine WHY. I know people right now who "welded" for years with the wrong polarity, and it was nothing BUT spatter and slag! You could pull welded steel stuff apart with your hands! SO, common scenario: Wrong polarity, way high travel speed, AND many starts and stops, so that a lot of "weld" is trying to deposit on to SLAG! (Engineering students are doing this) I sometimes pull off an allegedly welded thing with my hand, and yell "Either I'm SUPERMAN, or something is WRONG HERE!". I'm not actually any good at welding, but I can watch KZbin videos, read old books and yell. It's something!

[@vicferrari9380]

Lincolnelectrictv PLEASE give Jody a call. I'm amazed that this is the best you can do with your arc shots. Call him he does a great job of letting you see the weld in process. It would help me greatly to see the manipulation of the arc. And please let us see the slag coating before you remove it. The color, shape and coverage all will help us. Thank you DanO

I never weld on a bench where I can hold the tip perfect. I'm always on the ground reaching around something and barely fit the tip to the weld.

[@WRMonger1]

Paul M indeed, gravity is not your friend... since you mention it I don't think that I've seen a single vertical or inverted (upside down) weld in any of these videos. I hate overhead welding, the hot stuff always finds a way inside of your leathers...

What is the best set up for using an invectec v275-s for flux core welding?

[@Cb138inRs]

So. This wire suitcase I've been using doesn't have a wire feed speed control. Which is really frustrating. How do I mitigate that? Just up the volts if it's stabbing or globbing?

[@ThisTall]

very thorough video, i just bought a Miller 211 and am learning to weld with flux core .030 wire. im noticing that my spatter is 10x worse then anything im seeing here. my welder has an auto feed setting where you just choose material and wire, and the machine does the rest, i tend to think its accurate based on reviews and my own experimenting with manual settings.

[@lincolnelectrictv]

Check your polarity. If not, test drive a Lincoln and see if your problem is just the welder itself.

[@RPB-nx7vj]

Your 211 will make a very nice bead using FCMA but polarity needs to be changed on the machine from electrode positive to electrode negative, you will notice the difference in s lot nicer weld with less splatter

would have been nice to see the puddle guess i expected more from lincioln i can pro tig and hold my own stick welding but never flux welded before the way i see it its just stick welding with a really skinny constant feed stick i wonder if like stick wire some don't spatter as much as others or is the flux selection very limited

[@russellrussell3190]

+Kilian John My thought exactly!!! I took welders training over 30 years ago, and THEY HAD VIDEO WITH A FILTER THAT ALLOWED YOU TO SEE THE WELDING PROCESS!!! Without it, this is far less useful, and A WASTE OF TIME to watch the actual welding - you might have well just cut immediately to the result, since watching a bright arc for any time at all serves no purpose!!! Pretty sad for a company like Lincoln, you'd think they'd know better.

[@lincolnelectrictv]

+Russell Russell Thanks for your feedback. Other than the lack of puddle video, what other suggestions do you have for an informative video? Most other comments suggest that this video was quite helpful but we'd like to get better. Your suggestions will be welcomed and appreciated.

[@russell2449]

I concur with what he said. I took training with the military and their videos SHOW exactly what is happening in the puddle, after all THAT is what is important from a visual aid. I don't care how much others find this helpful, if you aren't going to be able to actually see what's happening then you might as well leave out simply watching a bright light, it's just not useful. That you don't know this is rather strange in my opinion.

[@leonardpearlman4017]

@@russellrussell3190 I don't think that's entirely true, because we're talking about gross faults, where the sound and light changes in a big way. Sometimes you can hear someone making a mess of this from across the room. So this is good information too. I would sure like to see "helmet cam" footage with it too.

[@nathanielstone9464]

Can you make a video shot through a hood? FCAW is hard enough to see the puddle, this is just a blob of white light. Also, less exaggerated settings would be helpful. Videos tend to show the extremes of bad voltage or feed, but do little to show how to achieve a glass smooth weld.

[@lincolnelectrictv]

We will do our best. Its hard getting the camera that close to flux cored because of the spatter.

[@jimjulie1]

Nathaniel Stone I agree....

[@ccswelding1599]

because putting the "glass" from a welding hood in front of a camera is real hard

[@WestCoastDP]

Well, I'm a pro videographer. Most of us use a zoom lens on our cameras. . We're about 4 to 6 feet away. Plenty away from the action. After the wide shot we stop the camera and cut to the CU (Close Up) of the weld. We have several neutral density filters and can stop down to F16 to see the bead without blowing out the whites. Easy, really.

[@lincolnelectrictv]

Thanks for your input. I agree, very easy. Unfortunately we are using DSLR lenses. I have a 100mm Macro, but again, we need to be fairly close to get the shot we want.

Good luck, that thing uses AC so all the welds look terrible.

[@salgarcia3258]

depending what you're welding, I would set the welder up in the lowest setting. you don't want to burn through your material. if the weld is cold, either make another pass, on low setting, or go to the high setting.

[@ODWALLA123]

Great video

[@bobstovall9570]

I have a suggestion that would be helpful for beginners watching these, otherwise, very excellent videos. In most of these videos the speaker uses phrases such as "...use DC Negative polarity...". That is actually a meaningless phrase to a beginner watching the video because it is impossible to know whether the presenter means 'Positive ground" or "negative ground". While the presenter obviously knows how to weld and is very articulate I sense that he is using phrasing that, while it may be understood by every professional welder on the planet, it is as unhelpful and confusing to the neophyte as if he were speaking Sanskrit. Please be precise when making points such as this. Thank you.

[@243WW]

The reference to Neg (-) or Pos (+) is always in respect to your electrode. A welding unit is not grounded either, if it was it wouldn't work. The "ground" is the return. This completes the circuit that is in fact, a controlled short circuit. The electrode is like a "fuse". Hope this helps Bob.

Hi great vid, but agree about being able to see the puddle and wire, and also the jargon about the polarity, seems you need to be an elecrician too, i purchased a sealey mightymig 100 and apparently there junk but what i could afford without going for used, no ball park settings on the welder and only set up of machine putting wire in and handle on so no help what so ever, wondered if you could help it says the machine comes ready to go so as I've never welded before i wouldn't really know if its the right polarity as my welds would be as bad either way, so could you tell me is there machines like this that can't or shoildnt have the polarity changed, any input would be great, thanks in the uk

[@Graham_Wideman]

I googled for a manual for the MightyMIG 100, but there are perhaps multiple models. The manual I saw for the "No Gas" model said to use flux-core wire (no surprise) and that the torch was connected to positive, which would be wrong, and puzzling since this machine can't handle gas. So could be a mistake in the manual, or actually an incorrect design. At any rate, it's simple to check -- just connect a voltmeter (set to say 200V) with meter negative lead to the ground clamp and the meter positive to the welding wire coming out of the torch. If the meter shows a positive voltage -- the torch is positive, and incorrect for flux-core. Most welders have a way to reverse the polarity, as shown in this video. However the MightyMIG doesn't show a way to do that, and would not need to if it was already wired correctly for flux-core. I suppose there's an outside chance that the Sealey flux-core wire TG100/1 is actually supposed to run on electrode positive. The product page is unhelpful: www.sealey.co.uk/PLPageBuilder.asp?id=20&method=mViewProduct&productid=8473

[@richardburdyn9577]

when do you either straight line drag and push the puddle as compared to washing it side to side and make e, c or I???

[@lincolnelectrictv]

+Richard Burdyn Thanks for the question. Sorry for the delay. On heavier material when you are needing a slightly larger weld than you can get with a straight line drag, a weave is fine to do. Some codes do have requirements on weaving and weld sizes made in a single pass so be carefull. Whether you use a C or zig-zag pattern is up to you just be sure you are never pushing the puddle. You risk trapping slag if you do that. Always use a drag technique.
