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.

Welding carts with tool-less securing systems are disclosed. In some examples, a welding cart may be configured to retain and/or transport a welding-type power supply. The cart and power supply may have bracket holes configured to receive bracket ends of a securing bracket. The bracket ends may be received by the bracket holes when a shaft retaining the securing bracket is engaged with a rotational lock of the cart. An actuator connected to the shaft may be configured to rotate the shaft to engage the rotational lock. A resilient member may bias the bracket ends out of the bracket holes when the shaft is disengaged from the rotational lock. A captive fastener attached to the shaft may ensure that the shaft and bracket remain captive to the cart even when the shaft is disengaged from the rotational lock and/or the securing bracket is biased away from the cart.

A welding guide has a plate having a first section and a second section that are bent along a bend line to form a right angle. Rollers are attached to the first and second sections and a positioning member having at least one aperture is attached to the second section. A top edge and a bottom edge of the first and second section have notches.

A welding cart with a cable management system may include a frame, a shelf adapted to support a welding machine, a plurality of upright members, a plurality of wheels supporting the cart, one or more pairs of holders disposed on one or more sides of the cart, and a removable bar that may be releasably secured to the one or more pairs of holders. The bar may be releasably secured to the holders via a pin-and-hole mechanism and may have a hook adapated to hold welding equipment such as cables. The bar may be releasably secured to a first pair of holders disposed on a side of the cart or a second pair of holders disposed on another side of the cart. This system provides additional, easily accessible storage space for welding tools and accessories while still being compatible with a wide variety of portable welding machines.

A welding sled, comprising a support base comprising one or more attachment points for attachment of a wire supply support and attachment of a wire drive assembly; a plurality of rollers coupled to a bottom of the support base; and a brake configured to selectively brake the welding sled.

Methods and apparatus for semi-automated tack welding of plies of a thermoplastic composite layup are described. An example welding tool includes a stabilization foot, a housing, a compaction foot, and a welder. The stabilization foot has a stabilization surface. The housing has a central axis. The housing is movable relative to the stabilization surface along the central axis of the housing. The compaction foot has a central axis and a compaction surface. The compaction surface is movable relative to the stabilization surface and to the housing along the central axis of the compaction surface. The welder has a central axis and a welding surface. The welding surface is movable relative to the stabilization surface, to the housing, and to the compaction surface along the central axis of the welder.

The present disclosure provides a stabilizer for a welding gun, wherein said stabilizer may comprise a plurality of sections hinged together to allow rotation with respect to each other and in connection with a user's hand. The stabilizer may comprise a holder designed to accept the end of a welding gun and a positioning device at one end to minimize movement of the welding gun. The stabilizer attaches to the user's hand and allows precise and repeatable welding movements. The stabilizer also allows a user to push fingers slightly, instead of constantly gripping the trigger.

The present application discloses a soldering apparatus including a driving portion for moving a soldering iron to perform soldering on a surface of an electronic board including soldering regions. The soldering regions have a base region and at least one replication region existing at a position different from the base region. The replication region has an arrangement pattern that is the same as an arrangement pattern of a soldering position in the base region. The soldering apparatus includes an input portion for receiving input of positional relationship data, which represents a positional relationship between the base region and the at least one replication region, and for receiving base pattern data, which represents the arrangement pattern of the soldering position in the base region. The soldering apparatus includes a controller which causes the driving portion to move the soldering iron based on the base pattern data and the positional relationship data in a soldering operation.

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.
