摘要： A torch lead extension is provided that comprises a conduit having a distal end and a proximal end. The torch lead extension further comprises a distal connector member disposed at the distal end of the conduit and a proximal connector member disposed at the proximal end of the conduit. The distal connector member is engageable with a torch lead connector member secured to a proximal end of a torch lead. The proximal connector member is engageable with a power supply connector member of a power supply. Generally, the distal connector member and the torch lead connector member comprise a distal quick disconnect, and the proximal connector member and the power supply connector member comprise a proximal quick disconnect. Accordingly, the torch lead extension may be quickly assembled between or disassembled from the torch lead and the power supply.

摘要： A gas distributor for use in a plasma arc torch is provided that has at least one plasma gas passageway formed conjointly with a metering passageway, and at least one helical gas passageway formed along an interior portion of the gas distributor, wherein the helical gas passageway is in fluid communication with the plasma gas passageway and the metering passageway. The combination of the metering passageway and the helical gas passageway provides for a metered flow rate and a controlled swirling flow of plasma gas within the plasma arc chamber, respectively, which functions to reduce the amount of molten emissive insert that is ejected from within an electrode at arc shut off, thereby resulting in an increased life of the consumable electrode.

摘要： A dual mode plasma arc torch is provided that preferably comprises a start cartridge disposed between an electrode and a tip. In one form, the start cartridge comprises an initiator that is in electrical contact with the electrode and that is resiliently biased into contact with the tip, such that when the plasma arc torch is in a contact start mode, the initiator is movable against the resilient bias to separate from the tip and establish a pilot arc between the initiator and the tip. Further, when the plasma arc torch is in a high frequency start mode, the start cartridge spaces the tip from the electrode such that a pilot arc is established between the electrode and the tip. In other forms, a contact start torch is provided that is operable under high frequency, and conversely, a high frequency start torch is provided that is operable under low voltage.

摘要： A plasma arc torch has a threadless electrode-cathode locking assembly, a one-piece tip assembly, and a rotational contact starting mechanism. The cathode and electrode of the locking assembly are configured such that relative rotation of the electrode with respect to the cathode causes the electrode to move in an axial direction relative to the cathode for locking the electrode in fixed axial and rotational position with respect to the cathode. The inner wall of the one-piece tip assembly is configured to receive the forward end of the electrode in a non-contact position. Rotation of the electrode with respect to the tip causes an arcing formation on the electrode to contact an arcing chamber within the cavity. Rotation of the electrode away from the tip generatesa pilot arc in the arcing chamber.

摘要： A contact start plasma torch and method of starting the torch includes a negatively charged cathode body and a positively charged anode body. A conductive element in the torch is constructed of an electrically conductive material and is free from fixed connection with the cathode body and the anode body. The torch is operable between an idle mode wherein the conductive element provides an electrically conductive path between the cathode body and the anode body and an pilot mode wherein a pilot arc is formed between the conductive element and at least one of the cathode body and the anode body. The pilot arc is blown by working gas flowing through the torch toward an exit orifice of the torch whereby the working gas is exhausted from the torch in the form of an ionized plasma.
