ABSTRACT:
An electrode (75) disposed within an insulating sleeve (86) is placed adjacent a work piece (9) to provide a selected gap between the electrode and the work piece. The atmosphere between the electrode and the work piece is first ionized and then a welding arc discharges between the electrode and the work piece. The orientation of the electrode can be adjusted by rotation of the electrode assembly (36), the amount of the gap by rotation of member (78), vertical placement of the electrode head 36 by eccentric means 40 and spacing between the terminus of the forward movement of arm (32) and the work piece station by adjusting the position of stop (54). Spacing of the electrode from the work piece enables the welding of similar and dissimilar metals such as fine wires of gold, silver, brass and others used in such applications as jewelry, medical, and electronic to provide the required strength, but without marring the surface of the work piece.
