That is what I was after, better weld penetration on heavy stuff and less heat use on thinner stuff. If you put a tiny bit (2% or 3%) of CO2 or possibly add some helium in with argon when stainless welding the weld spreads out better, now I put a ton of heat into my stainless welds and the weld doesn't spread any thing like MIG welding mild steel with CO2 or argon/CO2 mix.
Titanium welds great with pure argon.
