Zusammenfassung:	Apparatus for feeding wire at great distances, as in feeding electrode wire in electric welding. A plurality of wire-feeding mechanisms are disposed in tandem, each of such mechanisms being coupled to a DC motor, the DC motors being connected in parallel through individual back-polarizing diodes. The first or leading DC motor is connected via a speed stabilizer in a generator for switch-on impulses to a thyristor rectifier, the outputs of a rectifier being connected to the first DC motor. Each of the remaining DC motors is connected to the outputs of the thyristor rectifier, the connection of all DC motors to the thyristor rectifier being effected via a respective separating diode. The apparatus of the invention is particularly characterized by its simplified structure, while it still preserves all functional possibilities of prior art systems for feeding wire over large distances.
