ABSTRACT:
A welding gun having a swivel coupling joining the posterior end of the gun to the handle thereby allowing the handle and gooseneck to be rotated without having to rotate the posterior end of the gun and the wire cable feed line, the swivel coupling providing a conduit for welding gun wires and hoses and limiting the rotational range of the handle, thereby reducing stress to the wires and hoses.
