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.
