FIELD: machine building.
SUBSTANCE: group of inventions refers to standard interface for structure position, structure orientation, electrical connections and water chamber sealing for replacement of varieties of plasma forming nozzles each related to specific characteristic of plasma jet. Flexibility of nozzle connection is improved in comparison with previous designs due to standard external configuration of the nozzle and to clamping assembly of the nozzle on a plasma gun so, that multitude of nozzle configurations producing different characteristics of flow can be easily used with one device. Connection of the nozzle and a holder forms a channel for flow of coolant from the plasma gun via the nozzle and to a reverse channel into the plasma gun, thereby generating electrical contact between the plasma gun and the nozzle.
EFFECT: raised operational reliability.
