A portable device for precision plasma and oxy-fuel torch cutting is provided. Versions of an example portable cutting torch tool guide the gun of a cutting torch to make precision linear cuts or curved cuts in a metal workpiece. In an implementation, the device is a gun for a cutting torch, with an integrated rail follower and adjustable vertical and horizontal offsets from a workpiece. The cutting torch tool may use various kinds of rails for stable cuts, with optional movement damping, motorized drive, servos for vertical and horizontal offset, and remote control with user interface.

A pressurised welding habitat comprising; a housing configured to provide a sealed chamber, a port configured to connect to a gas supply and enable pressurisation of the chamber, and a sealing unit comprising a channel, wherein the channel is moveable relative to the housing and is configured to provide sealed instrument access to the chamber.

The invention relates a torch body for thermal joining of at least one workpiece, in particular for arc welding or arc brazing, said torch body comprising a non-consumable electrode provided in the body, in particular a tungsten electrode, for generating an arc between the electrode and the workpiece. The torch body has an end nozzle, which is devoid of potential, for discharging a shielding gas flow from a gas outlet. A secondary flow channel is provided for dividing the shielding gas flow into a main gas flow and a secondary gas flow, the secondary gas flow annularly surrounding the main gas flow at the gas outlet.

Disclosed systems include an enclosure comprising a base, a lift structure coupled to the base and comprising a first leg, a second leg, and a cross member, and one or more of, within the enclosure, an engine, a generator configured to convert mechanical power to electrical power, welding-type conversion circuitry configured to convert electrical power to welding-type power, an air compressor configured to output compressed air, a hydraulic pump configured to generate hydraulic flow, or auxiliary power conversion circuitry configured to convert electrical to at least one of AC output power or DC output power. The cross member, the first leg, and the second leg of the lift structure are a one piece structure.

A nozzle holder for a laser processing head of a laser processing system is provided. The nozzle holder includes a substantially cylindrical hollow body shaped to matingly engage a laser nozzle. The hollow body defines a longitudinal axis extending therethrough and a plurality of apertures dispersing around a circumference of the hollow body. The nozzle holder also includes a plurality of pawls configured to operably engage the laser nozzle within the hollow body by extending through the plurality of apertures of the hollow body. The nozzle holder further includes a sleeve substantially surrounding the hollow body and the plurality of pawls. The sleeve includes a pawl retractor that is movable along the longitudinal axis to physically displace the plurality of pawls axially and radially relative to the longitudinal axis for disengagement of the plurality of pawls from the laser nozzle.

A spark absorbing system for use with a cutting torch, comprises a cap having at least one spark opening therethrough and a spark capture unit coupled to the cap and positioned to capture sparks passing through the spark opening. The spark capture unit may comprise a tube extending from the cap and may include an outlet and a flow-reduction element positioned between the cap and the outlet and/or a spark accumulator between the cap and the spark capture unit. The flow-reduction element may comprise at least one baffle, screen or mesh. The spark absorbing system may further include a spark ramp extending from the cap opposite the spark capture unit and/or a shield, which may define a cutting space between the shield and the cap.

A tip attachment is disclosed. The tip attachment may an attachment body including a recess to fit on or in a tip of a device during programming of a robotic device. The attachment body may be structured such that the attachment body defines a set of angles of the tip during the programming of the robotic device. The recess may be sized such that the recess defines a distance between the tip and a workpiece during the programming of the robotic device.

A hole cutting apparatus for cutting a hole in a tubular structure, which includes a center shaft, a slide mount rotatably attached to the center shaft, a slide rail slidably attached to the slide mount; a cutter attachable to the slide rail so as to move with the slide rail, and a cutter height roller attached to the cutter. The cutter height roller is structured and arranged to maintain the cutter at a distance from a cutting surface of the tubular structure as the hole is cut.

A welding apparatus comprises support members adapted to support parts to be welded, a slit being defined between planes of the support members to expose the parts to be welded. A linear actuator unit having a carriage linearly displaceable along the slit. A welding unit is mounted to the carriage having a torch located substantially below the planes of the support members, and is adapted to be in proximity to the parts via the slit to transmit current to the parts to weld same.
