Claims4
In a device for moving a welding torch during the welding of circumferential seams and the like, which includes a chassis driven by a feed motor having a drive motor control unit and an auxiliary motor, characterized in that said device includes means for supplying an actual current to said feed motor, means for supplying a load current to said auxillary motor, means for sensing the actual current, means for controlling the load current based on the sensed actual current, and said feed motor and said auxiliary motor being coupled together in such a manner that the load current applied on said auxiliary motor is dependent on the actual current value of said feed motor.
Dependencies are inferred from the claim text.
