Abstract
Means for making electrical contact with a pair of spot welding electrodes and workpieces engaged by the electrodes. The means includes two rigid insulating blocks for mounting on each electrode of an electrode pair. Each block has a first electrical conductor for physically engaging the electrode upon which it is mounted and a second electrical conductor for physically engaging an exposed surface of the workpiece the electrode will engage in a welding process. The electrical conductors extend in a direction substantially perpendicular to the electrodes when the blocks are mounted thereon. In addition, means integral with the blocks and conductors for respectively electrically connecting the conductors to a device for measuring the voltage drop between electrodes and between the exposed surfaces of the workpieces when welding current is applied to the workpieces by the electrodes.
