WebJun 24, 2024 · When welding mild steel you typically use what’s called C25 gas (25% CO2 and 75% argon). For aluminum MIG welding you would use pure argon shielding gas. This will allow the spray transfer process to occur. For thicker aluminum (1/2” or more), anywhere from 25% to 75% helium is added. This allows for deeper penetration into the workpiece. WebJul 5, 2009 · ONLY straight Argon or Argon Helium mix (75-25) for ALL TIG on ALL metals, there are a few very special mixes for some very special situation but you have a long way to go before you get to that point. NEVER any CO2 or oxygen mixes for TIG, it will distroy the tungsten and contaminate the weld.
