摘要： A quick disconnect (10) for use in a plasma arc torch is provided wherein a plurality of connections disposed therein are configured such that the connections break in a specific order when the quick disconnect is disengaged. Preferably, the quick disconnect (10) comprises a plurality of signal pin connections (20), a pilot return connection (24), a fluid connection (30), and a main power connection (32). Accordingly, the signal pin connections break before the pilot return connection, the fluid connection, and the main power connection. Further, the pilot return connection breaks before the fluid connection and the main power connection (32), and the fluid connection breaks before the main power connection as the quick disconnect is disengaged. As a result, a safer quick disconnect in which both gas and electric power are conducted is provided by the present invention.

摘要： A plasma torch and method for cutting a workpiece under water directs a primary gas through a primary gas flow path in the torch to a central exit opening of the torch disposed on a longitudinal axis of the torch for exhaustion from the torch onto the workpiece in the form of an ionized plasma. The workpiece is submerged in water while the plasma torch is operated in closely space relationship with the workpiece to direct the ionized plasma upon the workpiece. A secondary gas flow path in the torch receives a secondary gas separate from the primary gas and directs it through the torch. Concentrically arranged first and second sets of secondary exit openings are disposed in the torch separate from the central exit opening and in generally radially spaced relationship with the longitudinal axis of the torch. The secondary exit openings exhaust secondary gas from the torch in a direction generally toward the workpiece. The secondary gas is exhausted from the first and second secondary exit openings at a flow rate sufficient to displace water surrounding the ionized plasma exiting the central exit opening of the torch to inhibit quenching of the ionized plasma.

摘要： A connector is provided that comprises a locking ring engaged with a housing, wherein the housing defines a first threaded portion and a second threaded portion, and the locking ring comprises a thread engagement member. The first threaded portion comprises a first pitch that is coarser than a second pitch of the second threaded portion, and accordingly, the thread engagement member engages the first threaded portion and the second threaded portion to secure the locking ring to the housing with a varying amount of axial travel per rotation of the locking ring that corresponds with the pitch of the first threaded portion and the second threaded portion. As a result, the locking ring initially engages the housing with a relatively small rotation followed by relatively larger rotations for complete engagement to a fully mated condition.

摘要： A plasma arc torch and method for improving the life of the consumable parts of the plasma arc torch, including the electrode, the tip and the shield cap. The method includes turbulating gas as it flows over the exposed surfaces of the electrode, tip and shield cap to increase turbulence in the hydrodynamic boundary layer of the gas flow, thereby enhancing convective heat transfer. The result of enhanced cooling has improved consumable parts life. For example, to increase the turbulence of the gas flow over the outer surface of the electrode, the plasma arc torch electrode has a roughened, or textured outer surface formed with dimples, axially extending grooves or spiraling grooves formed in the outer surface of the electrode. The inner and outer surfaces of the tip and the inner surface of the shield cap are similarly textured.
