Description
Cause1:The TorchMate sensor circuit indicates the wire is in contact with the touch plate before the search move (too much stickout-the search start distance is too small.) Cause 2: An electrical short exists in the touch circuit (for example, some circuits require a blocking diode on the power supply.)
Remedy
Remedy1: Decrease the stickout, increase the search start distance, or replace the bent torch. Remedy 2: Contact the supplier of your weld equipment regarding the touch circuit requirements and auxilliary wiring (if needed.)
