Re: FCAW burnthrough on 14 ga 1" square tubing

I have a Lincoln 180 and use flux core only. Not sure of the conversion but I use a lot of 100 wall tubing which I am guessing is in the 14 guage range. Once in a while I need to do a lap weld down to aprox 20 guage ( body metal) with mixed results but it can be done. I use Lincoln .035 all positio...

Re: FCAW burnthrough on 14 ga 1" square tubing

If you're moving slower and you burn through, then you need to adjust other parameters, including weld progression/sequence. For 0.030"-0.035" FC wire, I prefer a very short stickout at first. This gets the beginning of the weld a bit hotter than is intended. In the few milliseconds that ...

Re: FCAW burnthrough on 14 ga 1" square tubing

J Fitz, This might help. There's some mention of what parameters cause incomplete slag coverage. http://www.lincolnelectric.com/en-us/support/process-and-theory/Pages/video-fcaws-troubleshooting.aspx Good luck, Larry Thanks for posting that link! I watched it the other day, but went ahead and watch...

Re: FCAW burnthrough on 14 ga 1" square tubing

Some brands of flux core will leave a heavier slag covering than others. I've found cheaper "no name" bands don't leave as much as say a roll of Lincoln brand wire. What wire are you using? Pictures? i'm using lincoln 030 wire...still figuring out the forum, i'll try to get some pics up s...

Re: FCAW burnthrough on 14 ga 1" square tubing

The lack of slag Lack of slag, using FCAW? Flux-core wire welding (the "FC" in FCAW) uses flux instead of shielding gas, and absolutely definitely produces slag. Are you maybe using a shielding gas process? As you suspect it may be a heat issue: flux-core runs hotter, generally. You may b...

Re: Ever forget how to weld?

Re: FCAW burnthrough on 14 ga 1" square tubing

Welcome to the forum. If the structure you are welding has no job that will spend on strength of the weld you may have to switch weld and doing a quarter at a time or half at a time and give the metal time to cool off or take the lowest setting and put in multiple passes. Thanks! This is my first t...

Hey folks, first post on here for me...and the reason I decided to join. First, I'm not even close to an experienced welder. I've been "teaching" myself via youtube videos. Anyway, a while back I got a Lincoln weld pack 125 at home depot. It was completely different from my experiences wit...
