Abstract

PURPOSE: To move a main electrode in the groove width direction in such a manner that the arc voltages of both auxiliary electrodes become equal and improve the accuracy of controlling by disposing the auxiliary electrodes integrally on both sides of the main electrode moving along the groove.
CONSTITUTION: If a consumable or nonconsumable main electrode 3 and nonconsumable auxiliary electrodes 7, 8 are in the positive positions with respect to a groove 5, the detected values of the arc voltages of the electrodes 7, 8 are equal. If at this time the electrode 3 deviates rightward, the arc voltage E1 of the electrode 7 becomes larger than the arc voltage E2 of the electrode 8. The electrodes 3, 7, 8 are moved leftward in such a manner that the different of these voltages E1, E2 becomes 0, whereby the main electrode 3 is always aligned to the groove line 5. If the electrodes 3, 7, 8 all change in the height direction, the mean value of the sum of the arc voltages E1 and E2 of the electrodes 7, 8 is compared with the signal corresponding to the voltage of a reference height position and the electrodes 3, 7, 8 are integrally height-controlled in such a manner that these signals become equal.
