ABSTRACT:
Dressing device for the welding tips of a spot-welding machine consists of a single tool carried crosswise of a cylindrical opening in a tool holder. The tool holder has opposed slots supporting the tool, with one edge of the slots and therefore one side of the tool at the crosswise centerline of the opening. A cutting edge on that side of the tool and adjacent the tip dresses the tip to provide an essentially flat welding face. The holder and tool are rotated about the tip while the tip is held on an arm of a spot-welding machine. Preferably, when the dressing device is used in a high production situation, the tool is symmetrical and has a pair of outwardly-directed cutting edges on the centerline, simultaneously dresing two tips as they approach the tool from opposite directions.
