摘要： In some aspects, a consumable for plasma arc torch that generates a predetermined plenum pressure from a substantially constant preset gas supply pressure from a plasma arc torch power supply, where the substantially constant preset gas supply being used to support plasma generation for a selection of multiple consumable components that each generate a different plasma plenum pressure for carrying out different processes, can include a proximal portion shaped to connect to the plasma arc torch and define a plasma gas inlet region; a distal portion shaped to define a gas outlet; and a pressure-matching stage comprising a pressure wall defining at least one flow path between the gas inlet region and the gas outlet configured to establish sufficient fixed pressure drop of a flow of gas flowing through the pressure-matching stage to reduce a pressure of the flow of gas to the predetermined plenum pressure.

摘要： A front end assembly for a plasma torch and methods for assembling and disassembling a torch wherein a plurality of front end parts form a unit that is removable from, and installable in, the torch in a single operation without a special fixture. The front end assembly includes a nozzle retaining cup body connectable to a body of the torch, and a forward end connectable to a shield retainer. A nozzle retaining cup insert fits into the nozzle retaining cup body. The shield retainer has an inner surface for retaining the shield. A nozzle is received within the nozzle retaining cup insert. A stop on the nozzle engages the nozzle retaining cup insert when the front end assembly is removed from the torch so the nozzle does not remain in the torch. The shield engages an insulator, which engages the nozzle, to limit forward axial movement of the nozzle.

摘要： An electrode for a plasma arc torch is provided with features for improving electrode wear. An emissive insert is received into a cavity formed along one end of the torch body. A portion of the emissive insert is separated from the torch body by a sleeve positioned along the insert near the emission surface of the insert. The sleeve can operate to slow the erosion of the electrode body and thereby improve overall electrode life.

摘要： A plasma arc torch that includes a torch body having a nozzle mounted relative to a composite electrode in the body to define a plasma chamber. The torch body includes a plasma flow path for directing a plasma gas to the plasma chamber in which a plasma arc is formed. The nozzle includes a hollow, body portion and a substantially solid, head portion defining an exit orifice. The composite electrode can be made of a metallic material (e.g., silver) with high thermal conductivity in the forward portion electrode body adjacent the emitting surface, and the aft portion of the electrode body is made of a second low cost, metallic material with good thermal and electrical conductivity. This composite electrode configuration produces an electrode with reduced electrode wear or pitting comparable to a silver electrode, for a price comparable to that of a copper electrode.
