ABSTRACT:
A plasma torch electrode (132) comprises multiple platelets (159) oriented transverse to the electrode axis and joined together to form an electrical connection therebetween. A first group of the platelets have openings aligned to form an axial bore (164) for generating a plasma arc. A second group of the platelets define channels (172,178) aligned with each other, transverse to the electrode axis and in communication with the bore for injecting a gas, such as an inert gas, into the bore. In a specific embodiment, the plasma torch electrode comprises first and second end plates (152, 154) and a midplate (160), with the platelets stacked between and joined to the end plates and the central plate. This configuration allows precise fabrication of gas channels within the first and second sets of platelets while only requiring a small number of separate components to manufacture the plasma torch electrode.
