Electrode - Wikipedia

No external shielding gas is required, and a majority the wires run in direct-current electrode negative, meaning most of the heat is generated in the filler metal wire and not the base material. GMAW, on the other hand, is direct-current electrode positive, which generates most of the heat in the base material.
