G9-power Copper coated Mig Welding Wire The metal inert gas (MIG) process uses a consumable electrode, which is usually in the form of a copper-coated coiled wire. Argon is used to shield the weld, and direct current with the electrode being positive to generate more heat for melting. Available in all Sizes 0.80 mm, 1.00 mm, 1.20 mm, 1.60 mm Systematic Copper Coated Wire, Wire Gauge: 0.80 mm, 1 mm and 1.20 mm Shape: Round Usage/Application: Industrial Applications: Automobile Silencers, Petrol/Diesel/Gas Tanks, Scooter, Automobile Body, LPG Gas Cylinders etc. What Is MIG Welding? Mig Welding Wire is used in MIG (Metal Inert Gas) welding and is also referred to as GMAW (Gas Metal Arc Welding) or MAG (Metal Active Gas) welding. It is an automatic or semi-automatic arc welding process. The welding process involves feeding a continuous and consumable wire electrode and shielding gas through a welding gun to weld the workpieces.
