ABSTRACT:
A plasma arc torch includes a torch body and a nozzle mounted relative to an electrode at a first end of the torch body to define a plasma chamber. The torch body includes a plasma gas flow path for directing a plasma gas from a plasma gas inlet to a plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion defining a cavity and a substantially solid, head portion formed integrally with the body portion defining an exit orifice extending from the chamber. The exit orifice has a converging inlet and an outlet, where the inlet has a radius of curvature, and the exit orifice has a length to diameter ratio of greater than 2.5.
