Abstract
A plurality linkages, preferably a robot holding either a spot welder with welding guns or the workpiece. The plurality of linkages move a spot welder with open tongs toward a first spot weld position. The welding guns are then closed on the workpiece and welding is performed at the first spot weld position. While the welding is being performed, parts of the plurality of linkages are advanced toward a second weld position while the welding guns remained closed at the first spot weld position. When the welding at the first position is finished, parts of the linkages are already advanced towards the second position, and the remaining linkages are then advanced to the second position. This allows the linkages or robot to move faster from one spot weld position to another.
