Abstract

PURPOSE:To always automatically control an arc point at a proper position even when the feed inferiority phenomenon of a carbon electrode rod is generated, by mounting a position detecting means for detecting the position of the arc point and a control means for controlling a moving means so that the arc point comes to the proper position. CONSTITUTION:When it is supposed that an arc point is shifted from the first position, arc light reaches three light receiving sensors 30a, 30b, 30c through the slit 32 of a reflecting mirror 31. The illuminances of the light incident to three light receiving sensors 30a, 30b, 30c respectively change. The deviations of the illuminances are detected by a deviation detecting circuit 48 and compared with each other by the second comparing circuit 46. This change is always monitored and, when the deviations are lost, the drive signal to both left and right motors 47a, 47b from comparing circuits 10a, 10b is blocked and the transfer operation of both carbon electrode rods 10a, 10b is stopped and arc discharge is continued on the center line of the reflecting mirror 31. By this method, the arc point can be always automatically adjusted to a proper position.
