ABSTRACT:
A ground adapter is used in conjunction with a C-clamp for providing a connection between a ground cable from, for example an electric arc welding machine, to a ground object such as a workpiece. The ground adapter and ground object are firmly retained in contact with one another by a conventional C-clamp. The ground adapter is comprised of a ground base which is designed to receive one or more electrical cables. A plurality of adjustable cowling members may be disposed about one pad or foot of the C-clamp and are releasably secured to the ground base. The location of cowling members on the ground base is adjustable which enables use of the ground adapter with C-clamps having pads of varying sizes. Upon tightening the spindle or threaded portion of the C-clamp against the ground adapter, the cowling members of which are in firm contact with one pad of the clamp and against the ground base, a reliable physical and electrical contact is maintained between the ground adapter and the ground object thereby enabling completion of an electrical circuit as, for example, is required during electric arc welding operations.
