ABSTRACT OF THE DISCLOSURE A control system which senses arc current and arc voltage and controls the feed of a carbon electrode in an air-carbon arc metal removal system having arc power produced by either a constant potential power source or a constant current power source comprising: a device for sensing the magnitude of the arc current and providing an arc current command signal; a device for sensing the magnitude of the arc voltage and providing an arc voltage command signal; feedback control means for controlling the feed of the carbon electrode toward and away from a workpiece in accordance with an applied input signal; and switching means for alternately applying as the input signal to the feedback means (1) the arc current command signal when the constant potential source provides weld power thereby to maintain the arc current at a predetermined value, or (2) the arc voltage command signal when the constant current source provides weld power thereby to maintain the arc voltage at a predetermined value.
