Welding transformer and method of manufacturing same

摘要

A welding transformer for use in a resistance welding machine has primary and secondary coils. The primary coil comprises a plurality of spaced juxtaposed coil units mounted on a base board (30). Each of the coil units comprises a plurality of juxtaposed coil unit elements (20) with insulating members (38) interposed therebetween. Each of the coil unit elements (20) being manufactured by cutting a wound laminate of an insulating member (12) and a thin conductive member (10), into slices, and a plurality of conductors (36 a-c) mounted on the base board (30) and electrically interconnecting the coil unit elements (20).
