Abstract: The electric-arc plasma-steam torch has a housing accommodating coaxially arranged therein a nozzle anode and a cathode made fast in a holder. The housing communicates, via a pipe connector filled with a porous heat-conducting material, with a container. The container is filled with a moisture absorbent material which encompasses a tube running therethrough and made of a heat-conducting material. The tube has a flange at its end facing the nozzle anode. The flange is provided with passages on its end surface facing the nozzle anode. The aforementioned cathode holder is accommodated in the tube and is electrically insulated therefrom. A sleeve made of a heat-conducting material is interposed between the nozzle anode and the tube flange. The sleeve has passages on its outside cylindrical surface and on the surface contacting the nozzle anode.

Abstract: An electric-arc plasma torch has a body (1) having an axially arranged nozzle-anode (2) and a cathode (4), as well as a container (6) for working fluid, filled with a moisture-absorbing material (7). A nozzle (5) interconnecting the body and the container is filled with a porous heat-conducting material (8). The fluid absorbed by that material vaporizes, and the resultant steam passes through a ring (9) provided with passages, into a discharge chamber (11).
