Abstract
A resistance welding machine in which a wire electrode is urged into contact with a workpiece by first and second electrode wheels, the wire having first and second surfaces extending parallel to the axis of the wire and a twisting mechanism located in the path of the wire after the first electrode and before the second electrode for twisting the wire during linear motion of the wire so that the surface of the wire presented to the workpiece at the first electrode wheel is also presented to the workpiece at the second electrode wheel.
