Abstract
A system and associated method for determining an operational condition of a gas torch are provided. The system includes a diode device that is electrically connected between the workpiece and the nozzle. A sensing circuit is configured to provide an electric potential across the diode device and sense a resulting voltage characteristic of the condition of continuity of the system. For example, the sensing circuit can determine whether the nozzle is otherwise electrically connected to the workpiece and/or whether the nozzle is electrically connected to the electrode. The sensing circuit can determine the condition of continuity throughout the operation of the system, e.g., to verify the proper assembly of the torch, to verify proper movement of the electrode or nozzle, to verify that the torch is separated from the workpiece at start-up, and the like.
