FIELD: electrical engineering. SUBSTANCE: dummy and output electrodes of linear plasma generator are provided with solenoid manufactured in the form of pair of magnetic lenses. Lens distant from interelectrode gap of one solenoid and lens other solenoid nearest to this gap form pairs connected to A. C. source through valves connected in opposition. Due to this lens operation in turn and each fix of arc to electrode moves from lens to lens with frequency of supply current ensuring magnetic scanning of arc fixes. In addition solenoids can move along length of electrodes. EFFECT: prolonged service life of unit through expansion of scanning region of spot of arc. 2 dwg
