ABSTRACT:
A robot positioned welding tip dresser assembly includes a pivot arm pivotally mountable on a welding gun apparatus. The pivot arm is pivotal about a pivot point. A welding tip dresser is mounted on a distal end of the pivot arm. A first retaining tab extends from the pivot arm. The first retaining tab includes an opening extending therethrough. At least one positioning mechanism is disposed relative to the pivot point and is cooperable with the first retaining tab to retain the pivot arm in one of a home position and a working position. The first retaining tab is engagable by end-of-arm tooling of a robot. The end-of-arm tooling is operable to release the positioning mechanism, and movement of the robot moves the pivot arm between the home and working positions.
