Abstract (en)
[origin: EP0208134A2] 1. Apparatus for the plasa cutting of metallic workpieces with an electrode which, accompanied by the formation of a central area (14), is surrounded by a nozzle body (24), which has the plasma bore (26), which is centrally surrounded by a plurality of fine bores (27) in the nozzle body, characterized by the construction as a single-gas apparatus, in which the plasma gas and the cooling gas are constituted by the same gas, which enters the central area (14), from which the plasma-forming gas fraction flows through the centrally arranged plasma bore (26) in the nozzle body (24), whilst the gas fraction used for cooling purposes flows through the fine bores (27) located around the plasma bore (26) in nozzle body (24).
