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.
Equipment Preparation. 1  Check your cables: Before striking an arc, check your welding equipment to make sure all of the cable connections are tight fitting and free of fraying or other damage. 2  Select electrode polarity: MIG welding requires DC electrode positive, or reverse polarity. The polarity connections are usually found on the inside of the machine. Set gas flow: Turn on the shielding gas and set the flow rate to 20 to 25 cubic feet per hour.
