ABSTRACT:
A resistance welding system having a low-inertia movable welding head coupled to a stationary welding transformer which is of low mutual reactance. Through an appropriate timing circuit and control, a high-energy pulse of current, of very short time duration, is transmitted through the welding transformer to the movable welding head. The welding head, which contacts a projection on overlapping components, effects a rapid welding of the components, and the welding head rapidly follows up the melting of the projection due to its low inertia.
