What type of electrode is used in MIG welding?

Explanation:
MIG welding uses a continuously fed solid wire electrode that travels through the welding gun and into the arc. This wire supplies both the filler metal and the conductor for the arc, melting as it’s fed to form the weld pool, while shielding gas protects the arc and molten metal from contamination. A flux-core wire is used in a related process (flux-core arc welding), where the core provides shielding and deoxidizers, but that’s not the standard MIG setup. Tungsten electrodes are used for TIG welding, and flux-coated rods are used for shielded metal arc welding (stick).
