an integrated plasma cutting system includes a plasma cutting power supply and a motion control device to move a torch along a desired cut path relative to a workpiece . the system also includes a torch height control device to adjust a gap between a tip of the torch and the workpiece and a gas control device to regulate a gas used in the integrated plasma cutting system . the system further includes a centralized controller that includes an integrated microprocessor architecture that controls a sequence of the plasma arc , controls the regulation of the gas used in the integrated plasma cutting system gases , and controls coordination of the movement of the torch along the cut path with adjusting the gap without aid of an intervening microprocessor architecture in any one of the plasma cutting power supply , the motion control device , the torch height control device and the gas control device .
