Correct Gas For Mig Welding Stainless Steel. This can either straight Co2 and Argon or a Argon Helium Co2 mix. The addition of helium to argon increases the available energy to the weld pool making it more fluid.

Gases for all types of stainless steels The right gas mixtures for TIG and plasma welding VARIGON He30 This argon and helium gas mixture is suitable for TIG welding all grades of stainless steel. Gases such as high helium and argoncarbon mixture are ideal. I realize now that that was probably a more expensive gas than I needed to weld stainless.
The best gas for MIG welding stainless is 975 Argon 25 CO2.
Welding of stainless steel is typically done with mixture of Argon and Carbon Dioxide gasses that can be as low as 2 carbon Dioxide to as high as 25 carbon Dioxide. Although the gas flow rate will depend on a lot of factors as I have explained before the preferred range for working on stainless steel is around 20 to 25 CFH. When MIG welding stainless steel the correct choice of gas matters a lot you can use pure Argon or a blend of Argon and other minor gases. GAS FLOW RATE FOR MIG WELDING STAINLESS STEEL.
