Abstract: A lower electrode dressing tool for a projection welding machine is disclosed. The present invention includes a rotary dresser that refurbishes a projection welding lower electrode. The dresser utilizes the lower electrode's locating pin that stabilizes the dresser as its rotating cutting elements reshape and resurface the lower electrode. This allows for smoother and more accurate performance of the dresser.

Abstract: A lower electrode dressing tool for projection welding machine is disclosed. The dresser includes a rotating cutting mechanism that includes multiple cutting elements. The rotating cutting mechanism has an opening and locating pin in the interior of the mechanism that seats and stabilizes a lower electrode of a projection welding machine against the dresser. While the dresser is in motion, the multiple cutting elements ride against and dress the flat upper surface of the lower electrode.
