Shielding gas protection. Shielding gases for MIG/GMAW welding. The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades.
This is MIG welding, MIG standing for Metal Inert Gas. The gas is used to shield the molten puddle from the atmosphere and provide a clean environment for your weld. CO2 is the cheaper way to go, but I learned long ago that C25, which is 25% Argon and 75% Carbon Dioxide, produces a cleaner weld.
