ABSTRACT:
An apparatus for plasma working of electrically-conductive materials wherein a gas-cooled non-consumable electrode, insulator and a gas-cooled nozzle of a plasmatron are interlinked with one another so as to form a chamber subdivided by a gas-permeable partition so that one of its parts communicates with the atmosphere through a central passage of the nozzle serving to discharge plasma-forming gas and the other part of the chamber communicates with a source of plasma-forming and cooling gas and also with the atmosphere through an additional passage, the non-consumable electrode passing through this partition and being disposed coaxially with the central passage of the nozzle.
