ABSTRACT:
A welding unit of semi-automatic design for use in spot welding applications in which limited production volumes, low labor rates, and other cost-related factors negate the use of high production, fully automated units. The welding unit comprises two automatic feed GMA spot welding units disposed within a housing and parallel adjacent mountings which allow for fore-aft sliding movement relative to one another and having the weld heads projecting outwardly through the front face of the housing for contact with the work surface. Gear racks mounted in parallel face-to-face configuration on each weld head mounting, and pinion gear disposed between and in contact with the gear racks of each weld head, cooperate to translate fore or aft motion of one weld mount into opposite movement for the other. The assembly allows formation of an axially placed series of adjacent spot welds to be placed on a workpiece utilizing one unit.
