摘要： A method of starting a plasma arc torch is provided that includes directing a pre-flow gas and a start shield gas through the plasma arc torch during generation and transfer of a plasma arc, and switching from the pre-flow gas to a plasma gas, and switching from the start shield gas to a primary shield gas after transfer of the plasma arc to a workpiece. A method of stopping a plasma arc torch is also provided that includes directing a plasma gas and a primary shield gas through the plasma arc torch during steady-state operation, and switching from the primary shield gas to a stop shield gas during ramp down of an operating current.

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.

摘要： A method of operating a plasma arc torch is provided that includes directing a first portion of gas into a plasma chamber, directing a second portion of the gas to initiate a pilot arc in the plasma chamber, and redirecting the second portion of the gas to form a shield gas flow rather than venting the second portion to atmosphere. A plasma arc torch for this method includes a start cartridge disposed between an electrode and a tip for initiating the pilot arc. The start cartridge defines at least one redirect gas passageway in fluid communication with a shield gas passageway. The second portion of gas is redirected through the at least one redirect gas passageway and into the shield gas passageway.

摘要： Vented shield systems for plasma arc torches are provided that comprise a shield cup body defining a distal end portion, a vented retainer secured to the distal end portion of the shield cup body, and a shield cap secured to the vented retainer. The vented retainer defines at least one vent passageway that directs a flow of secondary gas inward toward the shield cap, and the vented shield system blocks at least a portion of molten metal from contacting components, such as a tip or nozzle, of the plasma arc torch. The shield cap may comprise a mechanized cap, a drag cap, a gouging cap, or a deflector cap, among others. Accordingly, various shield caps may be employed without removal or replacement of the vented retainer. The same vented retainer may be used throughout a variety of plasma arc torch applications.

摘要： A plasma arc torch is provided that comprises a set of torch consumable components secured to a torch head, wherein a supply of cooling fluid flows coaxially through the torch to cool torch components and a supply of plasma gas and secondary gas flows through the torch to generate and stabilize a plasma stream for operations such as cutting workpieces. The torch consumable components, in part, comprise an electrode and a tip that include a variety of configurations for improved cooling, electrical contact, and attachment to adjacent torch components. Further, a consumables cartridge is provided for ease of use and replacement of the torch consumable components. Additionally, methods of operating the plasma arc torch at relatively high current levels are also provided by the present invention.

摘要： A cooling system for a plasma arc torch is provided that comprises a coaxial fluid flow that improves cooling of components within the plasma arc torch and that provides a more compact torch design. The coaxial fluid flow, namely, the cooling fluid flow, is distributed circumferentially about the central longitudinal axis of the torch and is flowing in the same direction at any radial location from the central longitudinal axis. The cooling fluid flows distally towards the consumable components, then proximally towards the torch head, then distally again, and then proximally again for recirculation. Additionally, both the plasma gas flow and the secondary gas flow are also flowing coaxially in addition to the cooling fluid flow.
