  • Electrode for plasma arc torch and method of making same
    Patent number: 6114650
    Abstract: An electrode for a plasma arc torch comprises a copper holder having a lower end which mounts an emissive element serving as the cathode terminal for the arc during operation. A relatively non-emissive separator formed of silver alloyed with 0.5 to 4 percent of copper or other metals surrounds the emissive element and separates the emissive element from the copper holder at the exposed end face of the electrode. The separator serves to prevent the arc from detaching from the emissive element and attaching to the copper holder.
