摘要： The invention features a replaceable cartridge for a plasma arc torch. The cartridge includes a cartridge body having a first section and a second section. The first and second sections are joined at an interface to form a substantially hollow chamber. The interface provides a coupling force that secures the first and second sections together. The cartridge also includes an arc constricting member located in the second section; an electrode included within the substantially hollow chamber; and a contact start spring element affixed to the electrode. The spring element imparts a separating force that biases the electrode toward at least one of the first section or the second section of the body. The separating force has a magnitude that is less than a magnitude of the coupling force.

摘要： A consumable cartridge for a plasma arc torch is provided. The consumable cartridge includes an outer component defining a substantially hollow body, an inner component disposed substantially within the hollow body of the outer component, and a hollow region between the rear portion of the inner component and the outer component. The inner component includes a forward portion configured to axially secure and rotatatably engage the outer component to the inner component and a rear portion substantially suspended within the hollow body of the outer component. The rear portion is axially secured and rotatably engaged with the outer component via the forward portion. The hollow region is configured to receive a torch head to enable mating between the rear portion of the inner component and a cathode of the torch head.

摘要： An adapter for a plasma arc torch comprising a torch body is provided. The adapter includes a body defining a longitudinal axis between a proximal end and a distal end and at least one protruding portion extending from the proximal end of the body. The at least one protruding portion is configured to be inserted into a cavity of the torch body to physically engage a switch inside of the cavity. The engagement of the switch is adapted to indicate installation of a consumable component in the plasma arc torch.

摘要： A cartridge for an air-cooled plasma arc torch is provided. The cartridge includes a swirl ring having a molded thermoplastic elongated body with a distal end, a proximal end, and a hollow portion configured to receive an electrode. The swirl ring also has a plurality of gas flow openings defined by the distal end of the elongated body and configured to impart a swirling motion to a plasma gas flow for the plasma arc torch. The swirl ring further includes a nozzle retention feature on a surface of the elongated body at the distal end for retaining a nozzle to the elongated body. The cartridge further includes a cap affixed to the proximal end of the elongated body of the swirl ring for substantially closing the proximal end of the elongated body.

摘要： In some aspects, material processing head can include a body; an antenna disposed within the body; a first tag, associated with a first consumable component, disposed within a flux communication zone of the body at a first distance from the antenna, the first tag having a first resonant frequency; and a second tag, associated with a second consumable component, disposed within the flux communication zone of the body at a second distance from the antenna, the second tag having a second resonant frequency that is different than the first resonant frequency, where the first and second resonant frequencies are tuned based upon at least one of: i) a difference between the first distance and the second distance; or ii) a characteristic (e.g., shape) of the flux communication zone in which the first tag and/or the second tag is disposed.
