ABSTRACT:
An improved tip dressing process is provided wherein the pressure between the electrode tip of a resistance welder and the cutter of a tip dresser is varied during the tip dressing process. A pressure controller is also provided for controlling the pressure between the electrode tip and cutter during the tip dressing process. The pressure controller may be applied to independently control the tip dressing process of several resistance welders simultaneously.
