2-Level Foot Switch
- When a 2-Level Foot Switch is pressed to the first level, the Power Supply
energizes the Air Actuated Weld Head, causing the Upper Electrode to descend and apply force to the
parts. If the Foot Switch is released before the operator presses the Foot Switch to the second level, the
Power Supply will automatically return the Upper Electrode to its up position so that the parts can be
repositioned. Once the second level has been reached and the Force Firing Switch in the Weld Head has
closed, Weld Current will flow and the Power Supply will automatically return the Upper Electrode to its
up position.
