Techniques for assuring the accuracy of the welding of a part including a part calibration cycle, a tap check cycle and a gap detection cycle. The part calibration cycle determines the electrical load presented by the part to the welder transformer. The tap check cycle verifies that the operator has set the correct tap on the primary of the welder transformer, The gap detection cycle finds the actual spacing between the platen when the ends of the part are substantially touching so that the ends of the part can be accurately spaced at the beginning of the weld cycle.
