Abstract
A gas metal arc welding gun includes a power cable in which the power conductors are asymmetrically distributed in a crescent between a gas conduit and a sheath in order to improve flexibility of the power cable. The welding gun includes a head assembly which includes a head that defines an internal annular ridge between a contact tip and a free end of an electrode liner. This annular ridge serves as a stop for the contact tip, as a centering guide for the electrode liner, and as a shield to protect the electrode from welding spatter. The welding gun includes a two-piece handle which includes a tongue and aperture guide at one end, and an interlocking flange guide at the other end. The two guides restrict movement between the two housing parts to axial movement, and a snap ring locks the two housing parts in a desired assembled position.
