ABSTRACT:
A sheet metal working electrode handpiece is described for delivering electric current from a source of electrical energy to a selected location on a sheet metal workpiece. The electrode has an electrically insulated handle with an electrical conductor having a connector for electrical contact with a source of electrical energy. A control switch on the handle provides electrical connection to the source of electrical energy to control delivery of electrical energy to the conductor. A first electrode adapter is provided on the handle, oriented along a first axis. A second electrode adapter is also provided on the handle, oriented along a second axis substantially normal to the first axis. Any one of several sheet metal engageable electrodes may be removably mounted to at least one of the adapters. One such electrode is a dent pulling electrode which includes a shank, threaded at one end to be received in one of the adapters. The shank is formed of carbon steel and includes a flat reduced end for engagement with a workpiece. A torque surface is situated between the shank ends to facilitate securing the electrode to the handpiece or engagement with a tool used to twist the electrode on its axis. Other electrodes include a copper shank, spherical end heat shrinking electrode, a spot welding electrode, a nail head welding electrode, and a chrome strip clip welding electrode.
