    Abstract: Reduced scale nozzles for current loads of up to 400 A to be used in a liquid-cooled dual-gas plasma torch. The plasma flow passes through aperture in nozzle in direction. Aperture is divergent and expands in direction of the plasma flow. Aperture is of a conical shape at point, radius shape at point, and elliptic shape at point. Following its narrowest section, aperture expands at angle in direction of the plasma flow. Diameter at the end of aperture is larger than diameter at its beginning. Nozzle is equipped with mounting surface for insertion into the adapter. Nozzle contains seal, which prevents passage of a liquid and gas through the connection between nozzle and the adapter, which also provides attachment to the plasma torch.
