  • All The Inert gases

    The list includes

    Helium (He), (Mig Welding)

    Neon (Ne), (Well i wonder)

    Argon (Ar), (Mig Welding)

    Krypton (Kr), (Another Light source Mostly)

    Xenon (Xe), Mostly Used in Bright Lights(car lights, Stadiums)

    Radon (Rn).

  • MIG is -as he axplained- Metal INERT Gas. But CO2 isn not an inert gas. So he's talking about MAG (Metal ACTIVE Gas) welding.

    Intert gases used for welding are agron and helium.

    Active gases used are CO2, oxygen, hydrogen (and others). The later two only in small amounts mixed with inert gases.

  • brilliant

  • whats with the co2 machine?

  • He has C02 on his machine.
