100% Argon is used when tig welding stainless, and 308L rod is used to weld 304.
I don't know what you said, but your wrong.

They actually do make a gas-less flux core wire for welding stainless with a mig. I do know it's incredibly expensive though. Like $20 a pound.

For now I got a weldless fitting for it since its just the HLT. Once I get the proper gas I'll give it another go. Really just want to see if I can make it work with a MIG welder if at all possible since its what I have.
