1. A consumable set usable in a plasma arc torch to direct a plasma arc to a processing surface of a workpiece, the consumable set comprising:
a nozzle including: 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, wherein the nozzle exit orifice defines an exit orifice axis oriented at a non-zero bevel angle relative to the longitudinal axis; and an alignment surface located on an external surface of the nozzle, the alignment surface being generally parallel to the longitudinal axis and substantially planar, wherein 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. |
