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.
Gasless MIG (FCAW-Flux Core Arc Welding): 1  Does not need shielding gas, saves cost of bottles, regulator. 2  Wire is more expensive. 3  It is more portable, no gas to transport. 4  Uses flux core to shield weld. 5  Causes slag and spatter that must be cleaned up. 6  Produces smoke that makes it hard to see weld.
