Abstract

A welding gun is disclosed that includes an electrode configured to effectuate a welding-type process and a non-conductive nozzle configured to at least partially surround the electrode. The welding gun also includes a conductive casing at least partially surrounding the nozzle and electrically isolated from the electrode and a conductive path extending from the conductive casing through the welding gun.
