ABSTRACT:
An improved resistive electrode is disclosed for a welding apparatus for welding a battery terminal post to a battery bushing, The battery terminal post is electrically connected to a battery plate disposed within a battery case and the battery bushing is secured to a battery case cover with the bushing having a central bushing aperture for receiving the battery terminal post therein when the battery case cover is located on the battery case. The resistive electrode comprising a resistive electrode extending between a base end and a tip end with the base end being secured to a power source. A conductive member engages the resistive electrode for facilitating the flow of electric power from the base end to the tip end for concentrating the resistive heat proximate to the tip end of the resistive electrode.
