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.
It comes out of the same nozzle your welding wire is fed through so it literally creates a protective cloud around the arc as you're welding. A MIG welder is also a wire-feed type welder. The metal that it uses to create the weld material is held on a spool inside the welder. The type of material it uses depends on what type of metals you're joining, but it's always a metallic wire. For beginners, or for welders who need ultimate portability, some welding wire contains flux inside it, eliminating the need for a separate tank of welding gas. This works, but is inferior to a proper gas setup.
