Abstract: A consumable set is provided that is usable in a plasma arc torch to direct a plasma arc to a processing surface of a workpiece. The consumable set comprises a nozzle and an alignment surface. The nozzle includes: 1) a nozzle body defining a longitudinal axis extending therethrough, and 2) a nozzle exit orifice disposed in the nozzle body for constricting the plasma arc. The nozzle exit orifice defines an exit orifice axis oriented at a non-zero bevel angle relative to the longitudinal axis. The alignment surface is generally parallel to the longitudinal axis and substantially planar. The alignment surface is dimensioned to orient the nozzle exit orifice such that the plasma arc impinges on the processing surface of the workpiece at the bevel angle while the plasma arc torch is substantially perpendicular to the processing surface.

Abstract: An electrode is provided for use in a plasma arc torch. The electrode includes a body having an elongated forward portion and a ring-shaped aft portion. The forward portion is configured to provide an electrically conductive path from the distal end to the proximal end. The forward portion comprises a first conductive material. The ring-shaped aft portion, defining a hollow center, is configured to substantially surround a portion of the forward portion when the forward portion is located inside of the hollow center. The aft portion includes a pneumatic reaction region for receiving a biasing flow of a pressurized gas. The aft portion comprises a second material. In some embodiments, the first conductive material is the same as the second material.
