General Purpose MIG Guns
General purpose MIG (metal inert gas) guns are cooled by ambient air and shielding gas during welding tasks. They do not require an external radiator cooling system and hoses, so they are typically easier to set up and maintain and better suited for outdoor use and mobile welding applications than water-cooled guns. The guns hold consumable electrode wire and connect to a MIG welder to deliver current to the wire and create an arc between the wire and a metal workpiece. The heat from the arc melts and fuses the workpiece material and the wire material to create a weld. MIG guns let the welding operator control the position of the wire during welding tasks. Guns that are used in gas-shielded MIG welding also supply shielding gas to keep airborne contaminants out of the weld pool.
