Described herein are examples of torch tracking systems that monitor travel directions, speeds, and/or distances of welding torches using retractable cords. In some examples, the torch tracking systems use a sensor to measure a speed at which a reel extends and/or retracts a cord, and/or measure a length of the cord that is extended and/or retracted. The reel or cord can be attached to some portion of the welding torch, such that movement of the torch away from the reel causes the reel to extend more cord, and movement towards the reel allows a spring loaded spool of the reel to automatically retract the cord. While reel based torch tracking systems may provide coarser tracking than the more complex and/or expensive torch tracking solutions, their simplicity and low cost may make them an attractive alternative.

A method of operating a welding torch using a rotating coupler assembly that operates between 0 and 800 amps. The rotating coupler assembly allows for 360 degrees of rotation while keeping rotational friction at a minimum. The breakaway torque for the rotating coupler assembly is insignificant and the rotating coupler assembly can be rotated with little effort by hand. While the rotating coupler assembly minimizes rotational friction the design allow for rotating coupler assembly to continue to operate after 1-5 mm of wear on the contact surfaces. An embodiment of the rotating coupler assembly can be quickly disconnected from the unicable.

Aspects of a welding-type cable and torch are provided. The welding-type cable includes a power conductor to conduct welding-type power and a weld torch interface on a distal end of the welding-type cable to attach a weld torch to the power conductor. The welding-type torch includes a power connector to transfer welding-type power between the welding-type torch and a power conductor of a welding-type cable that is detachably coupled to the power connector. An electrode to perform a welding-type operation using the welding-type power is also provided.

A method and apparatus for providing welding type power includes a phase shifted double forward converter having a first and second converter with a controller and an output rectifier. The output rectifier has at least one cathode current path that creates a cathode magnetic field when current flows in the cathode current path. The output rectifier also has at least one anode current path that creates an anode magnetic field when current flows in the anode current path. The cathode current path is disposed and oriented and the anode current path is disposed and oriented such that the cathode magnetic field acts to at least partially cancel the anode magnetic field.

Some examples of the present disclosure relate to apparatus, systems, and/or methods for providing a quick connect and/or disconnect for a gas diffuser and/or neck assembly, for example, in a welding system. The gas diffuser may include threaded grooves and/or protrusions configured to engage with screw threads and/or channels of the neck assembly. The screw threads, protrusions, threaded grooves, and/or channels may be configured such that the gas diffuser may be quickly connected to, and/or disconnected from, the neck assembly.

The invention relates to a pair of two nozzle assembly receptacles (14, 15) for a dual-wire welding torch (1) for two melting welding wires (2, 3), having a torch body (4), a connection (5) for a hose package (6), and having a common gas nozzle (11) and to a dual-wire welding torch (1) with a pair of two nozzle assembly receptacles (14, 15) are constructed as inserts for accommodating and fastening in interfaces (12, 13) in the torch body (4) provided therefor, and the nozzle assembly receptacles (14, 15) respectively have an opening (16, 17) for the accommodation of a nozzle assembly (7, 8) in each case, which openings (16, 17) are arranged at an angle (α) between 0° and 20° to one another, so that the central axes (a, b) of the contact tubes (9, 10) or the welding wires (2, 3) running therein enclose this angle (α) to one another.

A MIG/MAG welding torch body includes a second channel, which is arranged coaxially to the central channel, and a further third channel, which is arranged coaxially to the second channel, wherein a connection is provided between the second channel and the third channel. The first channel has an orifice in the center of the receiving part, the second channel has an orifice on the lateral side of the receiving part, and the third channel has an orifice on the lateral side of the receiving part.

Consumable electric arc welding electrodes producing high chromium creep resistant steel weld metal compositions are also described.

The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation to reduce the amount of hydrogen introduced into a weld. Using embodiments of the systems and methods disclosed herein, one passes a wire through a pre-treatment chamber in which a wire is treated to release hydrogen and/or other contaminants, and provides a gas flow through the pre-treatment chamber so that the contaminants that are released from the wire are taken up by the gas. The gas exiting the pre-treatment chamber may be isolated from the shielding gas utilized during a welding operation. For instance, the pretreatment gas may be directed away from the distal end of the welding torch, thereby preventing released contaminants from being transported into a weld.
