MIG (Metal Inert Gas) welding is a type of welding that forms an electric arc between the metal and a wire electrode. The electric arc between the metal and the electrode melts the metal and allows it to be joined. An inert gas shield travels through the welding gun‚ which serves as protectant from outside air contaminating the process. This process generally requires a direct current power supply‚ but sometimes alternating current power systems are used. Electrodes are wires that allow an electric
