A clamp adapted to engage a clamp receiving hole in a welding platen for tightly clamping a workpiece in a desired position. The clamp includes an elongated upright capable of extending into the hole, a stop member extending outwardly from a lower portion of the upright, the stop being wider than the mouth of the hole, thereby limiting the distance the upright extends into the hole, a clamping arm slidably mounted to the upright, the clamping arm comprising a frame portion, an elongated neck extending from the frame and a sleeve connected to the neck and engaging the upright, the sleeve permitting changes in the angular position of the neck with respect to the upright. The clamp further includes a threaded screw connected to the frame and capable of applying force to the workpiece wherein tightening of the threaded screw against the workpiece causes the clamping arm to pivot with respect to the upright, thereby causing the upright to tilt and tightly engage opposing sides of the hole which causes the upright to remain wedged in the hole and the workpiece to be tightly clamped.
