Welding Stainless with Flux-core

[Sapper33]

Ok, so to weld stainless steel with gas, use argon heavy, and stainless wire.

What about when using gasless? I'm using Flux-core, as gas just isn't practical for me.

I went down to the scrap yard today and found a bunch of really nice stainless steel in a range of sizes...and it was cheap so I grabbed a bunch. So is there anything I should be doing differently to weld it? Currently in the Mig is 0.035 Lincon alloy wire

I am not sure about the filler types over in Canada, but in the UK, you still need to use Gas 80Ar 20Co2 for welding CrNi Flux cored wire.

If you want to use solid wire, then you need 2% Co2 98% Ar, or a tri mix Ar, Co2,Helium mix.

I have not heard of gasless wire for welding CrNi before.
