FIELD: welding. SUBSTANCE: arranged in zone of arc gap between electrode and work is excitation initiator in form of burr which is made on work before arc. Burr height corresponds to height of arc gap and its thickness amounts to 0.05-0.15 of electrode diameter. Welding device has torch with nozzle and cutter installed under torch nozzle for contacting with its flat surface of its holder with nozzle end face. Nozzle holder has hole coaxial to nozzle hole, holder hole size corresponds to nozzle inner diameter. EFFECT: higher efficiency. 2 cl, 3 dwg
