FIELD: electricity.
SUBSTANCE: in stator slots of three-phase asynchronous welding generator there is laid excitation winding (1), operating windings (2) and (3). Excitation capacitors (4) are connected to excitation winding (1); compounding capacitors (5) and the first rectifier (6) are connected to operating winding (2); the second rectifier (7) and controlled inductor (8) are connected to operating winding (3). Outputs of rectifiers (6) and (7) are connected in parallel to welding electrode (9). Rotor (10) of generator is caged.
EFFECT: increasing welding current and decreasing magnetic loss during on-load operation.
