Copper core weld gun
First Claim
1. A modular weld gun assembly, comprising:
- a modular body, including first and second pivot units pivotally connected about a pivot joint along a pivot axis;
first and second moment arms formed separately from the body and adapted for attachment to the first and second pivot units respectively for pivoting the pivot units;
a modular electrode system adapted for attachment to said pivot units for carrying coolant and electric power through the pivot units for welding; and
a drive member connected between the first and second moment arms for actuating the arms.

Abstract
A copper core weld gun assembly is provided with a substantially omega (Ω) 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.
