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?
