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 angle relative to the longitudinal axis; and an alignment surface generally parallel to the exit orifice axis, the alignment surface being dimensioned to align the exit orifice such that the plasma arc impinges orthogonally on the processing surface of the workpiece, wherein (i) the alignment surface is configured to lay at least substantially flush against a guiding surface angled relative to the processing surface of the workpiece and (ii) the longitudinal axis of the nozzle body is oriented at an acute angle relative to the alignment surface. |
