Welding Stainless Steel - shielding gas question
 

I ran outta shielding gas for my mig welder. I've mainly been welding mild steel, but I plan on welding stainless steel in the near future. What percentage of shielding gas should I get? I currently have 75% argon, 25% co2. I was told to run 100% argon for stainless steel. Will it be a lot different welding mild steel with this percentage?

Mig welding stainless steel
 

You use an argon /C02 oxgen. mix on stainless, 100% argon on alum. only when mig welding. argon when tig welding.
