摘要： A frame for a replaceable, unitary consumables cartridge configured for installation into a plasma arc torch. The frame includes a hollow body adapted to receive a translatable contact start electrode. The body has an internal surface and an external surface and includes: a substantially cylindrical metallic core; an electrically insulative overmolded plastic casing at least substantially surrounding a circumference of a distal end of the substantially cylindrical metallic core; and a set of flow passages fluidly connecting the external surface of the hollow body and the internal surface of the hollow body, the flow passages offset to impart a swirling fluid flow pattern to a plasma gases passing therethrough.

摘要： A consumable cartridge frame for a liquid-cooled plasma arc torch is provided. The consumable cartridge frame includes an insulator body configured to be disposed between a torch head and a cartridge tip. The consumable cartridge also includes a first cooling channel, disposed in the body, configured to conduct a first fluid flow received from the torch head to contact a component of the cartridge tip connected to the cartridge frame. The consumable cartridge further includes a first return channel, disposed in the body, configured to conduct at least a portion of the first fluid flow from the component to the torch head. The first cooling channel and the first return channel are non-concentric in relation to a central longitudinal axis of the body.

摘要： A torch head for a liquid-cooled plasma arc torch is provided. The torch head includes a torch body and a torch insulator, coupled to the torch body, having a substantially non-conductive insulator body. The torch insulator includes (i) a first liquid coolant channel, disposed within the insulator body, configured to conduct a fluid flow from the torch head into a consumable cartridge along a first preexisting flow path, (ii) a first liquid return channel, disposed within the insulator body, configured to return at least a portion of the fluid flow from the cartridge to the torch head along the first preexisting flow path, and (iii) a gas channel, disposed within the insulator body, configured to conduct a first gas flow from the torch head to the cartridge along a second preexisting flow path. The first and second preexisting flow paths are fluidly isolated from each other.

摘要： A nozzle for a plasma arc torch is provided. The nozzle includes a substantially hollow, elongated nozzle body capable of receiving an electrode, the body defining a longitudinal axis, a distal end, and a proximal end. The nozzle also includes a swirl sleeve attachable to an interior surface of the nozzle body, the swirl sleeve configured to impart a swirling motion to a gas introduced to the nozzle. The nozzle additionally includes a nozzle tip connected to the proximal end of the nozzle body, a nozzle shield, and an insulator configured to connect the nozzle tip and the nozzle shield to electrically insulate the nozzle shield and the nozzle tip from one another while transferring thermal energy therebetween.

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 plasma arc torch is provided for use in a plasma cutting system. The plasma arc torch includes a torch body for conducting electrical current. The torch body includes a torch tip configured to pass the electrical current to at least one consumable component connected to the tip. The plasma arc torch also includes at least one antenna positioned relative to the torch tip. The antenna is used to wirelessly detect the presence of the at least one consumable component. The plasma arc torch further includes a detection circuit configured to permit passing of the electrical current from the torch tip to the at least one consumable component based on at least the wireless detection.
