摘要：
A method of determining a failure event of consumable for a plasma torch is provided. The method includes monitoring at least one of an operating current or an operating voltage during a transfer arc mode of the plasma arc torch. The method also includes determining when at least one parameter associated with the operating current or the operating voltage exceeds a tolerance threshold for a time period indicative of the failure event. The method further includes shutting off at least one of the operating current or the operating voltage of the plasma arc torch when the at least one parameter exceeds the tolerance threshold for the time period.
