The torch height to the work piece determines the quality of the cutting process. The material to cut is not even in height. The voltage across the torch during the process is coupled to the height of the torch. The higher the torch, the higher the voltage will be. Since the torch is coupled to the Z-axis of the CNC machine, the voltage can be kept constant by regulating the height of the torch. This can be done by feeding the (attenuated and isolated) torch voltage to the CNC system. This system will control the height of the Z to keep the voltage constant.
