Abstract
A method of manufacturing an electrode for use in a plasma arc torch is provided that includes forming a conductive body to define a proximal end portion, a distal end portion, a distal end face disposed at the distal end portion, a central cavity, and a central protrusion disposed within the central cavity near the distal end portion. A plurality of emissive inserts are inserted through the distal end face and into the central protrusion. The plurality of emissive inserts are pressed into the central protrusion and both a proximal end portion of the central protrusion and the plurality of emissive inserts are deformed such that the plurality of emissive inserts extend radially and outwardly from the distal end portion at an angle relative to the distal end portion.
