ABSTRACT:
A plasma torch control system includes a data storage device that stores optimum arc voltages as a function of real torch powers supplied to the torch, wherein an optimum arc voltage is a voltage for which the torch has maximum torch efficiency for a real torch power, a ramping regulator that ramps the real torch power to a power reference value and keeps a real arc voltage of the torch within an error margin of an optimum arc voltage stored in the data storage device, and a stabilizing regulator that stabilizes the real torch power around the power reference value and keeps the real arc voltage within an error margin of an optimum arc voltage stored in the data storage device.
