  • Is there one "do it all" gas for MIG welding?

    Q. Is there one "do it all" shielding gas for MIG welding? I primarily use 75Ar/25CO2 on mild steel, but would like to be able to do aluminum and stainless, too. If not, what gases would be required? (Submitted by: Russell Selkirk from Port Neches, TX)

    A. If you ever invent the "do it all" gas, I want to be one of your investors!! Unfortunatly there is not one gas that can do it all right. Your 75/25 selection on mild steel is great. For aluminum you should use 100% Argon. A tri-mix of He, Ar and CO2 is the right way to do stainless. Hope this helps. Good luck.

    All purpose mig gas

    If you are near and Air-Gas Mid America dealer, be sure to check out their MAXX line of shielding gases. I have had great success with the Ferromax Plus for short arc and spray with my XMT 304. This is a good (all around) gas for carbon steel, but your still stuck with another gas for stainless, aluminum, etc. You may find info at
