Abstract
A cutter of a tip dresser for welding gun has three blades, one of which is extended to a central position of the cutter and includes a flat portion and an upstanding portion. A cutting edge is formed on the flat portion reaching from the central position to the upstanding portion. With such arrangement of the cutter, the tip is satisfactorily cut by the cutting edge even in the vicinity of the central position where its circumferential speed is slow.
