摘要：A control system for air-carbon arc metal removal in which the arc isautomatically controlled and in which the arc power is produced by either a constantpotential or constant current power source. For a constant potential source, the arccurrent is maintained at a predetermined value by sensing the magnitude of the arccurrent and for a constant current source the arc voltage is maintained at a
predetermined value by sensing the magnitude of the arc voltage. The presence of an arccurrent above a threshold is sensed for a predetermined interval to provide relativemotion between the workpiece carriage and the electrode. If the electrode arc currentdrops below a predetermined threshold, a low current sensing circuit is actuated. If thearc current remains below the threshold for a predetermined time interval, the carriagetravel is terminated. If the arc current remains below the threshold for longer than apredetermined amount of time, the electrode power is turned off. In addition, if the arcvoltage drops or remains below a threshold for a predetermined time period, theelectrode power is also turned off.
