Abstract
A cutting system including a plasma arc torch having an electrode, nozzle, and a gas conduit through which gas is transferred to a torch tip. The torch includes at least one of a sensor and a set circuit, where the set circuit stores a parameter related to the torch. The system also includes a power supply outputting a cutting waveform to the electrode via an electrical connector to initiate a working arc. The working arc creates a plasma arc using the gas. The system further includes a controller that controls an output of the power supply and a feeding of the gas through the gas conduit based upon input from a user input device positioned on at least one of the torch and the power supply. The controller monitors at least one usage parameter. The system additionally includes a memory device that is coupled to the controller. The memory device stores data related to the at least one usage parameter.
