Abstract
PURPOSE: To eliminate the need for pulling around an electric cable and make the device adaptable even to the case when the weld line is close to the walls, etc. of the walls of works, by constituting the device by the 1st and 2nd drive rings, drive device and wire feed motor.
CONSTITUTION: If in the case of performing welding while feeding a welding wire 34 along the weld line 13 the both of a wire feed motor 12a and drive motor 12b are run, the 1st drive rings 7, 7a, i.e., plate 16 and welding torch 8, wire feeder 9, etc. turn about the stationary pipe at the speed corresponding to the running speed of the motor 12b. On the other hand, the 2nd drive rings 35, 35a turn faster by the speed corresponding to the running speed of the wire feed motor 12a than the 1st drive rings 7, 7a. According to the speed differences between the 1st drive rings 7, 7a and 2nd drive rings 35, 35a, a deviation occurs between an internal gear 36 and pinion 33 and since the pinion 33 revolves according to this deviation, the wire feed roller 17 is revolved by a drive shaft 32.
