    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 tamper resistant pin connection for use in a plasma arc cutting apparatus is provided that comprises a plurality of locking fingers within a hollow internal channel of a housing that secure a negative lead gas carrying pin within the housing. The pin comprises a first collar with a shoulder disposed thereon, and accordingly, the locking fingers engage the shoulder to secure the pin within the housing. The pin further comprises a second collar that blocks access to the locking fingers through a first portion of the hollow internal channel such that the locking fingers cannot be accessed to disengage the pin. Further, the pin is recessed within a second portion of the hollow internal channel to prevent further access to the pin for a tamper resistant pin connection.

    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: 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 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.
