ABSTRACT:
A copper core weld gun assembly is provided with a substantially omega (.OMEGA.) shaped cross-section taken through each arm of the assembly. Concentric copper tubes are provided to carry cooling water and electric current to the electrodes of each arm. Special fittings are provided to insure that cooling water is carried directly to and from the electrodes without contacting the body, thereby eliminating galvanization in aluminum bodies. The design includes wedge-shaped barrel locks, crown-tipped incoming water tubes, thimble-shaped female electrode caps, and provides modular design capability. A modular gun design separates the gun into three fundamental areas: (a) the electrode system; (b) the body/frame system; and (c) the moment arm design.
