A hands-free striker assembly for use with a torch cart for igniting a torch attached to the torch cart. The hands-free striker has a mounting body mounted to the torch cart having a striker tip for lighting the torch. The hands-free striker also has a friction pad for lighting the torch by passing the torch over the friction pad and into contact with the striker tip.

A straightening device for welding wire is provided with two sets of roll groups, having a plurality of straightening rolls with which bends in a welding wire are straightened by passing the welding wire through the two sets of roll groups. The plurality of straightening rolls configuring the roll groups, are arranged at a predetermined arrangement interval along a passing direction of the welding wire in such a way as to face with each other across a straightening path along which the welding wire passes, and the two sets of roll groups, are arranged so that the directions in which they face across the straightening path are different from each other. By configuring the straightening rolls by small-diameter rollers, adverse effects on the welding wire are suppressed, and the welding wire is straightened finely.

A welding wire conveyor device (1) and a method for locking a pivotable roll receiver off the welding wire conveyor device (1). The device includes a drive roll receiver (11) and a pivotable pressure roll receiver (10). The pressure roll receiver (10) is coupled to a pivotable actuation mechanism (20) enabling movement to a pivoted position. The pressure roll receiver (10) may be locked in the pivoted position by a locking device (200).

A system and method provide gasless, mechanized, field welding of an exterior of a tubular structure such as a pipeline, without the need for an enclosure. An embodiment consolidates some of the welding equipment on a skid for ease of transport to and from a remote worksite. The gasless weld may be achieved despite the presence of wind, by precisely controlling an arc voltage as disclosed. The footprint and weight of the system may be minimized, along with the associated labor, expense, and environmental impact otherwise incurred by conventional welding techniques using enclosures.

A system includes a welding power supply. The welding power supply includes circuitry configured to produce power for a welding operation. The welding power supply also includes a compartment interior to the welding power supply and configured to hold one or more welding electrodes. In addition, the welding power supply may include a covering configured to be removably disposed in an opening of the compartment to allow access to the welding electrodes in the compartment.

A hands-free striker assembly for use with a torch cart for igniting a torch attached to the torch cart. The hands-free striker has a mounting body mounted to the torch cart having a striker tip for lighting the torch. The hands-free striker also has a friction pad for lighting the torch by passing the torch over the friction pad and into contact with the striker tip.

There is provided a portable welding system that includes a power supply unit and a wire feeder unit. The power supply unit includes power supply electronics and a power supply housing sized and configured to house the power supply electronics. The power supply housing includes a base face and an opposing upper support face. The wire feeder unit is detachably engaged with the power supply unit. The wire feeder unit includes a welding gun hose connection port sized and configured for connection to a welding gun hose. The wire feeder unit further includes a wire spool and a wire feeder housing. The wire spool is attached to the wire feeder housing. The wire feeder housing has a bottom face and an opposing top face, and the wire feeder unit is detachably engaged with the power supply unit with the upper support face disposed adjacent the bottom face.

A welding system includes a welder configured to output power to form an arc between a stick electrode and a workpiece. The welder includes a compartment configured to receive and store additional stick electrodes, and the welder is configured to heat the additional stick electrodes stored in the compartment.

An apparatus for sorting and aligning one or more shear studs for loading a shear stud feeder may include a lift mechanism having a lower lift member configured to lift shear studs from a hopper and deposit them onto an intermediate landing. An upper lift member may be configured to receive the shear studs from the intermediate landing and deposit them onto an upper landing. An alignment channel may be arranged downstream of the lift mechanism and configured to receive the shear studs from the upper landing and orient them with an elongated open slot of a magazine of the shear stud feeder. The alignment channel may include a slot configured for the shear studs to pass through and into the elongated open slot of the magazine.

A torch cart includes a base for supporting first and second storage tanks, a wall provided between the tanks for separating the tanks, a container for housing a torch, a pair of holsters for holding a pair of fire extinguishers, and a hands-free striker mounted to the cart for igniting the torch. The hands-free striker has a tip and a friction pad for passing a torch tip over and igniting the torch.
