FIELD: application of protective coats; mechanical engineering, metallurgy and other industries. SUBSTANCE: proposed device has two electrodes, crimping nozzle, external annular nozzle and additional central nozzle whose axis coincides with point of intersection of axes of electrodes and cross sectional area is lesser than total area of remaining nozzles by 16-200 time. EFFECT: improved quality of metallization due to increased action of carrier gas in arcing zone. 1 dwg
