ABSTRACT:
A cutter and gear assembly for simultaneously dressing a pair of spaced aligned welding electrode tips comprise a housing with a power-rotated gear journaled thereon for rotation upon a first axis and having an axial bore at one end terminating in an annular seating flange and adjacent its other end having an annular groove. A dressing tool cutter assembly is axially nested within the gear, bears against the seating flange and has a plurality of axially elongated arcuate drive tangs nested within corresponding drive grooves within the bore. A snap ring is anchored within the annular groove and retainingly engages the cutter assembly. The cutter assembly includes a pair of symmetrical outwardly opening cutting elements upon its opposite sides, each cutting element including a plurality of angularly related inclined cutting edges having a profile corresponding to the contour of a pair of aligned electrode tips adapted for axial projection into and against the cutting elements upon the first axis.
