摘要： A plasma arc torch is provided which is convertible in the field as to be able to operate in either a transfer arc mode or non-transfer arc mode. The plasma arc torch comprises a torch body (10) having channels formed for the flow of coolant and plasma gas. The torch body further comprises an anode (12) and a cathode base (30) and terminates at a threaded connection point. Adapted to be assembled to the threaded connection by means of mating threads is, alternatively, either an end cap (40) or a cathode extension assembly (70), thereby establishing a plasma arc torch capable of operating in either a transfer arc mode or a non-transfer arc mode. When the end cap (40) is connected, the cathode base is not energized. The cathode extension assembly (70) contains a cathode extension (82) which connects to the cathode base on assembly.

摘要： In a plasma arc torch, an electrode (22) is movable axially into and out of electrical connection with an anode (20), typically a nozzle secured to one end of a torch body (12). A flow (26c) of pressurized plasma gas is directed to a plasma chamber (36) between the electrode (22) and the nozzle (20), preferably through a replaceable swirl ring (18) that closely surrounds and guides the electrode at a larger diameter shoulder portion of the electrode. A gas flow passage (48), preferably a spiral passage machined on the outer side surface of the shoulder portion, diverts a portion of the gas flow from the plasma chamber to a region above the electrode where it is vented to atmosphere. The passage is sufficiently constricted that a substantial pressure drop appears along the path, while at the same time allowing a sufficient flow to produce the desired cooling.

摘要： An arc plasma torch (10) includes a moveable cathode (14) and a fixed anode (16) which are automatically separated by the buildup of gas pressure within the torch after a current flow is established between the cathode (14) and the anode (16). The gas pressure draws a nontransferred pilot arc to produce a plasma jet. The torch (10) is thus contact started, not through contact with an external workpiece, but through internal contact of the cathode and anode. Once the pilot arc is drawn, the torch may be used in the nontransferred mode, or the arc may be easily transferred to a workpiece. In a preferred embodiment, the cathode (14) has a piston part (48) which slidingly moves within a cylinder (50) when sufficient gas pressure is supplied. In another embodiment, the torch is a hand-held unit and permits control of current and gas flow with a single control.
