    • An electrically conductive work-piece is rapidly heated by establishing a current flow in the work-piece that is the highest it can be without damaging circuit components. Such components include at least a transformer having a high-voltage, low-current primary winding and a low-voltage, high-current secondary winding and insulated cables connected to the secondary winding and terminated in one or more clamps that attach to the workpiece. The cables may be jumper-type cables and the clamps may be alligator-type clamps. Other types of clamps suitable for use with the present invention include a sliding clamp, a hinged clamp, and a wrap-around strap-type clamp. To limit current in the circuit to acceptable levels, it may be necessary to employ one or more resistive electrodes, or heater blocks, placed in the jaws of one or more of the clamps. Intimate thermal contact is established between the heater blocks and the work-piece such that heat generated in the heater blocks is conducted to the work-piece. Heater blocks of different configuration and/or composition are provided to present a range of resistances. For a particular application, a resistance is selected that will limit current flow to a level that will not damage the workpiece, the transformer and cables or the heater blocks themselves. In an alternative embodiment of the present invention, a conventional current limiter is used instead of resistive electrodes such that the maximum allowable current is consistently maintained through the work-piece.
    • 导电工件通过在工件中建立电流而被快速加热,该电流可以是最高的,而不损坏电路部件。 这种部件至少包括具有高压,低电流初级绕组和低压,大电流次级绕组的变压器以及连接到次级绕组的绝缘电缆,并且端接在连接到工件的一个或多个夹具中。 电缆可以是跳线型电缆,并且夹具可以是鳄鱼型夹具。 适用于本发明的其他类型的夹具包括滑动夹具,铰接夹具和环绕带状夹具。 为了将电路中的电流限制到可接受的水平,可能需要使用放置在一个或多个夹具的钳口中的一个或多个电阻电极或加热器块。 在加热器块和工件之间建立紧密的热接触,使得加热器块中产生的热量被传导到工件。 提供具有不同配置和/或组成的加热器块以呈现一定范围的电阻。 对于特定应用,选择一种电阻,其将电流流动限制到不会损坏工件,变压器和电缆或加热器块本身的水平。 在本发明的替代实施例中,使用传统的限流器代替电阻电极,使得通过工件一贯地维持最大允许电流。

    • 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.
    • 用于通过电流通过电加热电导工件的装置包括一对铰接杆,每个铰链杆具有把手端部和钳口端部。 每个杠杆的钳口端设置有选自不锈钢,镍铬合金,铬铬,钨和钼的难熔金属带加热器。 该带具有细长的横截面并被弯曲以形成V形接触器,以实现与诸如铜,铝或黄铜管和配件的相对高导电性的工件的良好的热接触。 铜导体确保金属带加热器的端部和颚部之间的良好的电接触,并且用作定位块。 螺栓和翼形螺母将金属带加热器可拆卸地固定到钳口。
