FIELD: plasma welding. SUBSTANCE: inner cavity 19 of electrode 8 is connected to central channel 17 by electrode holder 7 with displacement relative to the axis of electrode holder 7 in the direction opposite to the displacement of slot 20 of electric holder 7 from this axis. This intensifies cooling of electrode 8 due to improvement in water circulation in cavity 19 of electrode 8. Collector-distributor 15 and swirler 16 are additionally made in body 1. Collector-distributor 15 is connected to water feed union 2 by channel 13, and to the inner cavity of nozzle 11 by swirler 16. This provides additional cooling of body 1 by the plasma-forming gas passing through vortex gas ducts. EFFECT: improved cooling. 3 cl, 4 dwg
