ABSTRACT:
The insulating coating on the portion of a conductor wire to be fused to a terminal is evaporated prior to the fusing operation by the use of a focused inductive heater, such as an ultrasonic or laser beam, focused on the portion of the wire from which the insulating coating is to be removed. Following removal of the insulating coating in this manner, the terminal and the conductor wire are fused together by application of heat and pressure thereto. The invention is described for use in connecting armature coil lead wires to commutators having bars with tangs.
