Abstract (en)
An electrode for a plasma arc torch and method of fabricating the same are disclosed, and wherein the electrode comprises a copper holder defining two coaxial cavities. An emissive element is secured to one of the cavities and serves as the cathode terminal for the arc during operation. A relatively non-emissive separator is disposed about the emissive element within the other cavity, and acts to separate the copper holder and the emissive element, as well as resisting detachment of the arc from the emissive element and attachment to the copper holder. <IMAGE>
