Abstract
A welding ground clamp includes a pair of frame legs that are connected together by a pivot pin assembly that also establishes electrical contact between the clamp and a ground cable. The electrical contact is such that the electrical path between the workpiece engaging elements of the clamp and the ground cable are all essentially identical, and the connection to the ground cable is spaced from the workpiece engaging elements. A handle locking assembly combines the advantages of both a spring assembly and a screw lock assembly and is located away from the workpiece engaging elements.
