    摘要： Methods of forming an electrode for use in a plasma arc torch are provided that generally include forming an electrode body defining a proximal end portion and a distal end portion, forming a recess within the distal end portion, securing a slug within the recess of the distal end portion, creating a bore through the slug and the distal end portion of the electrode body, and securing an emissive insert within the bore. In another form, a hybrid electrode is provided, which is formed by the manufacturing methods of the present invention, and which includes an electrode body defining a cavity, a secondary body secured to the electrode body, and an emissive element secured within the bore and in contact with the secondary body and the electrode body, wherein the secondary body is not exposed to the cavity.

    摘要： A connector is provided that comprises a locking ring engaged with a housing, wherein the housing defines a first threaded portion and a second threaded portion, and the locking ring comprises a thread engagement member. The first threaded portion comprises a first pitch that is coarser than a second pitch of the second threaded portion, and accordingly, the thread engagement member engages the first threaded portion and the second threaded portion to secure the locking ring to the housing with a varying amount of axial travel per rotation of the locking ring that corresponds with the pitch of the first threaded portion and the second threaded portion. As a result, the locking ring initially engages the housing with a relatively small rotation followed by relatively larger rotations for complete engagement to a fully mated condition.

    摘要： A component for use in a plasma arc torch is provided that includes an orifice that defines a continuously changing cross-sectional size along the length of a surface of the orifice from an inlet portion to an outlet portion. The surface extends along the component and directs a flow of shield gas at a predetermined angle to result in a specific pierce or cut location on a workpiece. In one form, the component is a shield cap. The continuously changing surface may be convergent, divergent, or a combination of convergent and divergent according to the principles of the present disclosure. Additionally, the shield cap may comprise a single, unitary piece or alternately a plurality of pieces or components.
