ABSTRACT:
An apparatus for electrically heating an electrically conductive workpiece by passage of electric current therethrough includes a pair of hinged levers, each having a handle end and a jaw end. The jaw end of each lever is provided with a refractory metal ribbon heater selected from the group consisting of stainless steel, Nichrome, chromel, tungsten, and molydenum. The ribbon has an elongate cross-section and is bent to form a V-shaped contactor for achieving good thermal contact with a workpiece of relatively high conductivity, such as copper, aluminum or brass pipes and fittings. A copper conductor assures good electrical contact between the ends of the metal ribbon heater and the jaw and serves as a positioning block. A bolt and wing nut detachably secure the metal ribbon heater to the jaw.
