MIG welding aluminum requires different techniques than MIG welding mild steel. A. Before You Start Welding Material thickness that can be welded with MIG process or aluminum are 14 ga. [0.074 in. (1.9 mm)] or heavier. (How heavy depends on the output capacity of the welder being used.) To MIG weld aluminum thinner than 14 ga. either specialized pulsed MIG or AC TI
