    Argon being inert, each gas having a density, guess a mixing it up wouldn't hurt, anyone?

  3. For MIG welding steel, I use 75/25. For MIG welding aluminum, I use Argon. You can MIG weld steel with pure Argon, but the gas costs more, you won't get the penetration of the 75/25.
    For the TIG, I use pure Argon for everything.
    Buy your own bottles, it is worth the investment.
    Weldingtricksandtips, is a youtube site that has excellent information on MIG and TIG welding
