ABSTRACT OF THE DISCLOSURE: An apparatus for soldering the winding to the commutator of an electric machine, which comprises a bath with molten solder and electric resistance heaters, a single-phase magneto-hydrodynamic pump consisting of a magnetic core, surrounded by winding, and a stream-formation unit made of ferromagnetic material which is concentric to the magnetic core, a basis which is a hollow cylinder with conical internal bottom surface and radial holes arranged above the conical surface and a limiting ring, and of a changeable nozzle unit disposed concentrically on the basis and consisting of a tubular casing with chamfered upper end, which is rigidly fastened in a sleeve. The bath is disposed on the magnetic core, and on the bottom of the bath there is fastened rigidly an additional hollow magnetic core, which is a continuation of the magnetic core, while the tubular casing which is of stepped shape, seats with its external step on the additional hollow magnetic core. Concentrically to the additional hollow magnetic core there is disposed a stream-formation unit which consists of a cylindrical part, carrying the basis with limiting ring, and a disc, which is rigidly fixed to the bottom of the bath by means of distance inserts made of ferromagnetic material.
