Abstract: A fine wire welding machine for cold butt welding small diameter wires through a multiple upset technique. The machine includes a loading mechanism for accurately positioning the fine wire strands for subsequent engagement with the welding dies and the welding dies are movable in a plane parallel to their abutting faces for shearing the wires and aligning the end of the wire from one spool with the end of the wire from another spool for the subsequent welding technique. An improved operating mechanism is incorporated for operating the dies for movement in a predetermined sequence whereby the dies first move into gripping relation with the respective wire ends, the dies then move together to upset the wire ends, next the dies release the wire ends while still held in the upset position and finally the dies retract from their upset position for a repeat of the cycle.
