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.
