ABSTRACT:
Apparatus for resistance welding is provided. The apparatus includes a transformer, to an output face of which resistance welding electrode holders are connected. The output face has two terminal blocks with threaded openings to receive fasteners for several different designs of electrode holders. The welding electrode holders, being directly connected to the transformer, eliminate the usual heavy cables located between the welding electrode holders and the power source, thereby increasing efficiency through reduction of impedance and secondary loss. The transformer and electrode holders are essentially one unit which can also be moved about to different locations. The welding apparatus is also versatile and compact to meet various applications.
