摘要： A plasma arc torch includes an electrode, a tip, a third element, and a secondary power circuit. The electrode is disposed within the plasma arc torch and adapted for electrical connection to a cathodic side of a power supply. The tip is positioned distally from the electrode and adapted for electrical connection to an anodic side of the power supply during piloting. A plasma chamber is formed between the electrode and the tip. The third element is disposed near a proximal end of the plasma chamber. The secondary power circuit is disposed proximate the plasma arc torch and in electrical communication with the third element. The secondary power circuit is configured to generate a high voltage pulse on the third element using input to secondary power circuit to initiate a first arc to start the plasma arc torch.

摘要： A shield device for a plasma arc torch includes an inner shield member defining an inner auxiliary gas chamber and an outer shield member surrounding the inner shield member. An outer auxiliary gas chamber is defined between the inner shield member and outer shield member. The shield device allows an auxiliary gas flow to be split into a first flow of auxiliary gas through the inner auxiliary gas chamber and a second flow of auxiliary gas through the outer auxiliary gas chamber. The inner shield member and the outer shield member are configured to be mounted to the plasma arc torch as an integral unit.

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 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.
