Abstract
In some aspects, methods for preserving a usable life of a plasma arc electrode consumable installed in a plasma arc torch can include measuring a characteristic of an electrical signal being provided to the torch to generate a plasma arc between the torch and a workpiece to be processed; monitoring the characteristic during operation of the torch over a time period; comparing the characteristic to a threshold value; and, responsive to determining that a measured characteristic meets and/or exceeds the threshold value, initiating an arc extinguishing sequence to preserve the life of the electrode.
