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.
A tip configured for electrical contact and passage of a fluid between the tip and an adjacent anodic element of a plasma arc torch, the tip comprising a perimeter surface adjacent a perimeter surface of the anodic element, wherein the adjacent perimeter surfaces provide the electrical contact and the passage of the fluid.
A tip for use in a plasma arc torch, the tip being configured for coaxial fluid flow wherein the fluid flows distally and proximally to and from the tip, without a radial component.
A tip configured for electrical contact with an anodic element of a plasma arc torch, the tip comprising at least one passageway and a perimeter surface adjacent a perimeter surface of the anodic element,
A liquid cooled tip configured for electrical contact with an anodic element of a plasma arc torch, the tip comprising at least one passageway for passage of the liquid.
