ABSTRACT:
Electrode and nozzle that seat within a retaining member and in two different seating locations relative to retaining member. The electrode and nozzle each include an interwoven-double-start thread having two thread cuts, which start 180 degrees from one another as measured around the circumference of the electrode or nozzle. Further, the electrode, nozzle, and retaining member include mating frustum surfaces, which are configured and dimensioned so that the electrode and nozzle seat within the retaining member with less than one turn of the electrode and nozzle relative to the retaining member. Therefore, the electrode and nozzle may be quickly inserted in, and removed from, the retaining member.
