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 includes a nozzle having: 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 angle relative to the longitudinal axis. The consumable set can also include an alignment surface generally parallel to the exit orifice axis. The alignment surface is dimensioned to align the exit orifice such that the plasma arc impinges orthogonally on the processing surface.
