ABSTRACT:
An electrode for a contact start plasma arc torch includes an elongated electrode body formed of an electrically conductive material that defines a longitudinal axis and a distal end for housing an emissive element. The electrode includes a second end positioned adjacent the electrode body. The second end defines an extensive portion having a first length along a first direction and a second length along a second direction. The second length is greater than the first length. A component for use with the electrode includes a hollow body element having an interior surface with one or more of a contour, step, or flange that defines a shaped opening capable of slideably receiving a complementary-shaped portion of an electrode body.
