摘要： A medical pin index valve includes a pair of pin holes, the positions of which are selected based on the particular gas to be used with the pin index valve. The pin index valve includes a residual pressure device therein. In one embodiment, the residual pressure device is designed so that it closes the valve when the pressure in the tank is between 0.5 bar to 5 bar.

摘要： A torch for an arc process operation includes a handle and a trigger coupled to the handle. The trigger includes a base segment configured to rotate relative to the handle via a pivot, as well as an extended segment coupled to the base segment. The extended segment is configured to move relative to the base segment to transition the trigger between an extended configuration and a compact configuration, the extended segment extends away from the base segment in the extended configuration, and the extended segment extends along the base segment in the compact configuration.

摘要： A method performed in a welding or cutting system configured to deliver weld power to an electrode tip extending from a torch to create an arc on a workpiece, comprises: sampling a sensed voltage indicative of a weld voltage provided to the electrode tip, to produce voltage values; computing a time derivative of the voltage values to produce voltage derivative values that represent a contact resistance between the electrode tip and the workpiece; and upon detecting a decrease in the voltage derivative values from above a time-derivative threshold to below the time-derivative threshold as an indication of a weld start event, increasing the weld power supplied to the electrode tip to initiate the arc on the workpiece.

摘要： A torch having first and second housing portions may contain multiple adjustment features such as an adjustable length, an adjustable pivot angle of the second housing portion, and an adjustable rotational angle of the second housing portion. The second housing portion may be both slidably and rotationally coupled to the first housing portion. The second housing portion may be configured to slide along a longitudinal axis of the torch to adjust a length of the torch. The second housing portion may be further configured to rotate about the longitudinal axis of the torch to adjust the rotational orientation of the second housing portion with respect to the first housing portion. At least a section of the second housing portion may be configured to pivot about a transverse axis with respect to the first housing portion, the transverse axis being transverse to the longitudinal axis of the torch.

摘要： Apparatus and methods associated with operating a plasma torch are disclosed. According to some implementations, the apparatus and methods involve the delivery of a process gas to a shuttle valve at first and second pressures for the purpose of altering an axial position of a valve element located inside the shuttle valve. The shuttle valve is configured such that at different axial positions of the valve element the flow of process gas into the plasma torch is altered.

摘要： A method of assembling an electrode by securing together an emitter of the electrode inside an emitter holder while at the same time securing together the emitter holder inside a distal end of a tubular body of the electrode. According to one implementation the securing together includes simultaneously applying a proximally directed force to the emitter and a distally directed force to the emitter holder to cause a bulging of the emitter inside the emitter holder and a bulging of the emitter holder inside the distal end of the tubular body.

摘要： A cable hose suitable for welding or cutting systems includes one or more conductors and monolithic tubing that extends around and between the one or more conductors. The monolithic tubing defines one or more discrete passageways for the one or more conductors that provide a closed path from a first end of the cable hose to a second end of the cable hose for the one or more conductors. The monolithic tubing also defines an inner conduit configured to allow a gas to flow from the first end of the cable hose to the second end of the cable hose. The cable hose may be formed by arranging the one or more conductors in a specific configuration and overmolding an insulator onto the one or more conductors to secure the one or more conductors in a specific configuration.

摘要： Recognizing interchangeable torch components, such as consumables, for welding and cutting torches includes determining that one or more interchangeable torch components installed in an operative end of a torch are genuine. Operational parameters for the one or more interchangeable torch components can also be determined. When the one or more interchangeable torch components are determined to be genuine, an indicator assembly can be activated to provide a first indication. When the operational parameters are implemented at a power supply connected to the torch, the indicator assembly can be activated to provide a second indication.
