Trimix Gas For Mig Welding Stainless. Trimix 90 Helium 75 Argon and 25 CO2. Altogether the three materials create the best weld for stainless steel.
Therefore you do not want to use a completely inert shielding gas such as 100 helium or 100 argon for stainless steel MIG welding. Arc starting and stability characteristics. Not sure how heavy of stuff youre welding.
S - Trimix Helium Argon Co2 Mix quantity.
A unique mixture of Helium Argon and carbon dioxide is used in an approximate ratio of 85105. A unique mixture of Helium Argon and carbon dioxide is used in an approximate ratio of 85105. Arc starting and stability characteristics. Therefore the recommended shielding gas to use for short circuit stainless steel MIG welding is a tri-mix shielding gas such as 90He75Ar25CO2.
