ABSTRACT OF THE DISCLOSURE : An improved planetary-type wire-feeding mechanism including a pair of cooperating skewed rollers for advancing the wire is disclosed. The rollers are carried on a pair of radially reciprocable pistons mounted in a feed housing through which the wire is advanced, and a projecting rear portion of the housing has a threaded outer surface for receiving a force- adjusting nut. A conical guide element is slidably mounted on the outer surface of the rear housing portion, and is urged against the adjusting nut by means of a calibrated spring. A pair of symmetrically arranged two-arm levers entend longitudi- nally through a pair of slits in a flange integral with the housing intermediate its ends, with the rear end of the levers in contact with the conical guide member through a roller, and with the front ends of the levers maintained in abutting rela- tion with the outer ends of the pistons by means of springs. The shaft of a drive motor is fixedly connected to the rear portion of the housing.
