ARC PLASMA TORCH HAVING TAPERED-BORE ELECTRODE
An arc plasma torch having a tapered-bore electrode provides a long, columnar plasma arc. The torch includes a torch housing, a tapered-bore electrode, a gas-constricting nozzle, and a swirling gas flow generator. The electrode is mounted within the housing and has a closed inner end and an open out...

| description | An arc plasma torch having a tapered-bore electrode provides a long, columnar plasma arc. The torch includes a torch housing, a tapered-bore electrode, a gas-constricting nozzle, and a swirling gas flow generator. The electrode is mounted within the housing and has a closed inner end and an open outer mouth. The electrode has a longitudinally extending, tapered bore. The bore has its largest dimension at the mouth. The nozzle has a bore and is also mounted within the housing. The nozzle is in axial alignment with, forwardly spaced with respect to and insulated from, the tapered-bore electrode. The torch introduces a swirling flow of gas at a location intermediate the electrode and the gas-constricting nozzle, resulting in gas flowing past the electrode during use of the torch. In operation, an electric arc emanating from the electrode ionizes the gas flow. |
