PLASMA-TRANSFERRED-ARC TORCH CONSTRUCTION ABSTRACT OF THE DISCLOSURE The invention contemplates a plasma-transferred-arc torch construction wherein optionally, a single releas- able clamp enables rapid separation of downstream-end fittings of an anode subassembly and a cathode subassembly, as for inspection, servicing and/or replacement; in an alternative option, release of the single clamp enables rapid further disassembly of the entirety of the respective subassemblies from mounting structure which includes the single clamp. These options are available for torch structure incorporating provision for sealed independent fluid-flow supplies of (a) coolant serving both electrode subassemblies, (b) plasma gas serving an annular inter- electrode gap at the downstream end of the torch, (c) a metallic, ceramic or other powder fluidized in a carrier gas, for torch-deposition of the powder, and (d) shielding gas to protect -the zone of plasma-transfer of the arc and any powder conveyed therewith.
