FIELD: welding.
SUBSTANCE: invention relates to nozzle for arc plasma torch. Nozzle can include first housing, in which there are first end, second end and longitudinal axis, and second housing, located around first housing and mating with first housing. Second housing forms a set of channels on the inner surface, the shape of which provides formation of a set of fluid passages between the first housing and the second housing. At that, the second housing at least partially determines availability of at least one inlet and at least one outlet for this set of fluid passages.
EFFECT: technical result is higher safety of operation of plasma burner due to absence of need to eliminate used contaminated water, which can be considered as hazardous wastes.
