Abstract
A component for use in a plasma arc torch is provided that includes a continuously contoured surface extending along the component that directs a flow of shield gas at a predetermined angle to result in a specific pierce or cut location on a workpiece. In one form, the component is a shield cap that includes an exit orifice extending through a central portion of the shield cap, the exit orifice defining an inlet portion and an outlet portion, and a continuously contoured surface extending between the inlet portion and the outlet portion. The continuously contoured surfaces may be convergent, divergent, or a combination of convergent and divergent according to the principles of the present disclosure. Additionally, the shield cap may comprise a single, unitary piece or alternately a plurality of pieces or components.
