Welding Sch 10 Stainless with SS Flux Core ad 75/25
of course the wire is 'dual shield' or 'double shield' etc
i dont have ready access to a tig machine or a person who can tig however, after speaking with a couple welders about this, ive come to the conclusion that a .035 flux core stainless wire (more specifically 308LT1- 4) will work quite well with the 75/25 gas i have as well.
this is all for welding on 304 stainless pipe.
what would like to know is if anyone here has used such a setup and if so: how did it work out?

what designation? i know a lot of them have more subtle differences that arent easily noticed but id like to know for my own knowledge. the welder ive been talking to said that pretty much any flux core stainless would work well but thats quite broad..lol. sorry to be nit picky, just wanting a clear picture of your experience is all . eg: how stable the arc was, how easily the puddle formed and moved, slag formation or lack there of
ive seen the argon, co2, o2 mixture (90,8,2) pop up quite a few times as well doing research on this. it might an older 'go to' mixture but thats what ive run in to.

I would get the blue max to match the series of material you have. I do not remember the ratios on the tri mix but I remember it containing the 3 I mentioned and it was spray transfer not short arc. It worked very well in out of position conditions. Slag peels off by itself really but I would wire brush if making multiple passes. It was very controllable and had a nice arc. I think you would be better off using the 75/25 and short arc tho with the schedule 10 thickness. Get some and practice, see how it works for you. I would also backpurge too.

What is it that you are welding? The materials you are using are only a small part of the puzzle. If you want to maintain any quality of your stainless you better stay away from MIG welding unless you have an experienced stainless Mig welder and your fitting will have to be as close to perfect as possible. A modular spray transfer would be ideal. ALWAYS PURGE STAINLESS IF POSSIBLE, this is a very commonly overlooked and important step.
If its an exhaust and you dont care what it looks like and aren't worried about it rusting out in a year or two, go for it.
Another option would be to tack it together with your mig welder and send it to a TIG welder to finish up.... If possible that is.

i thought about tacking then taking to someone to tig but there isnt really anyone around here.
