Abstract
Warning and shutdown systems and methods are presented for providing advance warnings of pending fault conditions to an operator of an arc processing system. The warning system comprises an input, a logic system, and a signaling system, where the input receives a sensor signal indicative of an operational condition of the arc processing system, the logic system detects a pending fault condition based on the sensor signal, and the signaling system provides a warning signal to the operator, wherein the warning signal is indicative of the pending fault condition. Shutdown apparatus is provided which has a sensor input, a logic system to detect a fault condition, and a shutdown system that selectively shuts the arc processing system down a predetermined time period after fault detection.
