ABSTRACT:
Welding of similar and dissimilar metals such as fine wires of gold, silver, brass and others to provide required strength without marring the surfaces of the link is accomplished by mounting an electrode (75,264) a selected distance from the surfaces to be welded. A first high voltage ionizing arc of a selected atmosphere between the electrode and the surfaces to be welded is followed by a low voltage, high amperage welding arc. An electrode (75) is mounted in a discontinuous link forming machine (10) so that it can be oriented in optimum position relative to the work piece (9). An electrode (264) is mounted in an automatic chain making machine (200 ) so that it can be optimally adjusted in x and y directions employing target adjustment block 320, as well as in the z direction employing vertical adjustment block 290. The electrode (264) is mounted within an electrode head (260) provided with a tip portion (274) having a biased formed face (272) forming a weld window which is maintained free of slag build up by a combination of an inflexible wiper (384) and a flexible wiper (388).
