Can you tig welding stainless steel?
Quick answer
Yes — the quality default. TIG on stainless steel: TIG for quality, MIG with tri-mix or 98/2 argon-CO2 for speed; filler ER308L.
The verdict and why
The quality default. Low thermal conductivity but retains heat: lower amps (~10% under mild steel), faster travel, or it sugars and distorts
