ABSTRACT:
An anode for plasma torch that has a primary section and a secondary section with a gradual transition between the sections. The diameter of the hollow primary section tapers down toward a transition zone, at which point the anode formed by the sections makes a gradual transition to the secondary section. The secondary section is cylindrical and has a diameter larger than that of the primary section from which the plasma exists the anode. The transition zone will describe a generally conical surface and may include a convex radius on the neck where the primary and transition sections meet.
