摘要： Devices and methods are provided that control gas flow to a plasma arc torch local to a torch handle. Generally, a plasma arc torch is provided that comprises a gas control device operable with a torch lead and a torch head, and an activation member operable with the gas control device. Accordingly, the activation member activates the gas control device such that gas flow is supplied from the torch lead to the torch head, and the activation member deactivates the gas control device such that the gas flow is terminated. Further, the activation member may comprise a trigger system, a button, or a safety member, among others. Moreover, the gas control device may comprise a gas control valve or a switch that activates a gas control device disposed within a power supply, among others.

摘要： Methods and devices for controlling the flow of gases through a plasma arc torch are provided. A flow of plasma gas is directed to a plasma chamber, a first flow of auxiliary gas is directed around a plasma stream that exits a tip in one of a swirling manner and a radial manner, and a second flow of auxiliary gas is directed around the first flow of auxiliary gas and the plasma stream in one of a coaxial manner, an angled manner, and a radial manner. The first flow of auxiliary gas functions to constrict and shape the plasma stream to improve cut quality and cut speed, and the second flow of auxiliary gas functions to protect the plasma arc torch during piercing and cutting and to cool components of the plasma arc torch such that thicker workpieces may be processed with a highly shaped plasma stream.

摘要： A plasma arc torch is provided that comprises torch head connections that are made between consumable components and a torch head independent of rotational alignment of the consumable components. Accordingly, connections for the flow of a cooling fluid, plasma gas, and/or a secondary gas are made independent of rotational alignment. Additionally, electrical connections are also provided that are independent of rotational alignment of the various plasma arc torch components.

摘要： Plasma arc torches are provided that include a mounting for an electrode and a coolant tube telescopingly mounted on the plasma arc torch to engage and deliver coolant to electrodes of different sizes mounted in the mounting. The telescopingly mounted coolant tube may extend to a closed position in which coolant does not flow when no electrode is mounted in the mounting. The telescopingly mounted coolant tube may further be used to electrically connect a cathodic member with the electrode mounted in the mounting.

摘要： A quick disconnect for use in a plasma arc torch is provided that comprises a plug housing and a mating socket housing, a locking ring disposed around the plug housing secures the plug housing to the socket housing. A negative lead gas carrying pin is disposed within the plug housing, and a mating main power socket is disposed within the socket housing for the purpose of conducting both gas and electricity from a power supply to a plasma arc torch. Further, the negative lead gas carrying pin and mating main power socket are positioned off-center in order to provide additional volume for a plurality of signal conductors disposed within each housing, along with a pilot return conductor. Additionally, both the plug housing and the socket housing define a D-configuration in order to properly align the housings and conductors disposed therein, among other novel features of the present invention.

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.
