An adjustable cable fitting for a thru-arm cable of a robotic welding torch includes a female member formed of an elongated tubular body having a forward end, a rear end, and a through hole extending axially from the forward end to the rear end. The forward end includes a nose portion for connection to a welding cable. A male member is cooperable with the female member in a telescoping manner. The male member includes a shaft received in the through hole of the female member, a receiver connected to the shaft for receiving a power pin, and a through hole extending axially through the shaft and receiver. A nut is disposed on the shaft for locking a position of the shaft relative to the female member. Adjustment of a disposition of the male member relative to the female member varies an effective length of the power cable.

In order to reduce the accumulation of moisture on a welding wire (2, 2′, 2″) arranged in a welding wire cartridge (1, 1a, 1b) or to remove existing moisture in a simple and reliable manner, it is provided that a flow (D.sub.1) of purging air supplied to the welding wire cartridge (1, 1a, 1b) is adjusted by a flow control unit (14), the purging air is supplied to the flow control unit (14) at a first pressure (p) and is discharged at a purging air discharge (24) of the welding wire cartridge (1, 1a, 1b) at a third pressure (p.sub.at), and at a purging air feed (15) of the welding wire cartridge (1, 1a, 1b) a second pressure (p.sub.1) at the purging air feed (15) that is lower than the first pressure (p) results from the adjusted flow (D.sub.1), the third flow (p.sub.at) and a flow resistance between the purging air feed (15) and the purging air discharge (24), the relative humidity (rF.sub.1) of the purging air being reduced by the relief of pressure from the first pressure (p) to the second pressure (p.sub.1).

Disclosed is a welding-type power source that includes a first wire feeder provides a wire to a workpiece. A first wire feeder motor of the wire feeder to move the wire from a wire storage device to the workpiece. A second wire feeder motor moves the wire to and away from the workpiece and superimposes movement of the wire onto the movement from the first wire feeder motor. A moveable buffer located between the first and second wire feeder motors, and configured to accommodate a change in length of the wire between the first and second wire feeder motors when the second wire feeder motor moves the wire away from the workpiece. A sensor senses movement or displacement of the moveable buffer, wherein a speed or direction of the first or second wire feeder motors is adjusted based on data from the sensor.

A handheld welding torch for electric-arc welding with a melting welding wire has a wire feed unit for conveying the welding wire along a conveying axis arranged within a torch housing with a handle region, the wire feed unit including a drive unit with a rotation axis arranged vertically with respect to the conveying axis of the welding wire, a drive roller with a rotation axis and a counter roller with a rotation axis, and having a torch push-button. The wire feed unit has a gear stage and the rotation axis of the drive unit is arranged aligning with the conveying axis of the welding wire.

A welding rod dispenser comprising: a deck, where the deck angles downward from back to front; a rotating assembly located at the front of the deck, where the rotating assembly comprises grabber teeth; and a leveler assembly located atop the deck. Welding rods placed atop the deck may tend to slide forward under the leveler assembly where the leveler assembly levels them into a single layer. Individual welding rods may then be grabbed by the grabber teeth one at a time before being moved forward by the rotating assembly for retrieval by the user.

A method providing a manual welding apparatus configured to supply a welding wire to a welding gun. The welding gun has a trigger and an opening where the welding wire extends when the trigger is activated. The method also has a computer with a user interface that includes an automatic wire retract program. The program monitors the welding gun and determines when the trigger is disabled. The program indicates when a first condition is satisfied and retracts the welding wire so the welding wire does not extend from the opening of the welding gun.

A welding or additive manufacturing wire drive system includes a first drive roll having a first annular groove, a second drive roll having a second annular groove, a first welding wire located between the drive rolls in the annular grooves, and a second welding wire located between the drive rolls in the annular grooves. A biasing member biases the first drive roll toward the second drive roll to force the first welding wire to contact the second welding wire. The first welding wire contacts each of a first sidewall portion of the first annular groove, a first sidewall portion of the second annular groove, and the second welding wire. The second welding wire contacts each of a second sidewall portion of the first annular groove, a second sidewall portion of the second annular groove, and the first welding wire. The drive rolls rotate in opposite directions thereby moving the welding wires through the wire drive system.

Disclosed is a system for feeding welding wire for welding-type applications. The system includes a welding wire feeder and a separate wire source including a wire source housing. The wire source is connectable to and disconnectable from the wire feeder.
