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.

Submerged arc welding torches and systems to resistively preheat electrode wire are disclosed. A disclosed example submerged arc welding torch includes: a first contact tip configured to transfer weld current and preheating current to the wire; a second contact tip configured to conduct the preheating current to the wire; an air-cooled first conductive body portion configured to receive the weld current and to conduct the weld current and the preheating current to the first contact tip; an air-cooled second conductive body portion configured to receive the preheating current and to conduct the preheating current to the second contact tip; and an insulator coupled between the first and second conductive body portions.

A spool gun having a very unique look, due to its arrangement of features. The spool gun has its wire spool compartment located below the handle and the user's hand, when the user is gripping the spool gun in an operational position. Operably connected to the wire spool compartment is wire spool brake configured to engage with the wire wraps. The brake can have a lock and/or a wire spool life indicator. The wire spool compartment has a cover that is non-threadedly engaged. The feed rate of the wire from the wire spool compartment can be adjusted by a control device, such as a knob, located proximate the user's hand, when the user is gripping the spool gun in the operational position.

A system and method of welding or additive manufacturing is provided where at least two welding electrodes are provided to and passed through a two separate orifices on a single contact tip and a welding waveform is provided to the electrodes through the contact tip to weld simultaneously with both electrodes, where a bridge droplet is formed between the electrodes and then transferred to the puddle.

The present application relates to an arc welding arrangement and an electric arc welding method to be used with the arc welding arrangement. The arc welding arrangement comprising a first power source, a first electrode connected to say first power source, and a second electrode, said first electrode being adapted to generate a weld pool via a first electric arc present within a first arc region. The second electrode is operated at welding parameters adapted to ensure that excess energy from at least said first electrode is required to maintain said second arc ignited. The method comprises the step of feeding said second electrode so that it is allowed to consume excess energy from said first electrode to maintain said second arc ignited.

A welding tip includes a tip body having a wire insertion bore along a central axis and a leaf spring configured to press a welding wire onto a feeding point disposed on an inner surface of the wire insertion bore. The tip body 1a has an aperture on an outer circumferential surface on the distal end side. The leaf spring has a first end that is a free end disposed on the distal end side of the tip body and a second end fixed to the tip body. The aperture includes a first aperture accommodating the leaf spring and second apertures disposed in communication with the first aperture and configured to discharge wear particles created during welding to the outside.

A gas metal arc welding system for a robotic arm includes a j-arm, a power block, and a bolt. The j-arm has a first end and a second end each having a through hole. The power block has a first opening defining a first passageway along a longitudinal axis and a second opening defining a second passageway substantially along an axis perpendicular to the longitudinal axis. The bolt has a threaded portion configured to extend through the first opening of the j-arm and into the second passageway of the power block, wherein the bolt retains the j-arm to the power block. The threaded portion of the bolt comprises an internal passageway that extends through a longitudinal axis of the bolt, wherein the internal passageway of the bolt and the first and second passageways of the power block are in fluid communication with each other.

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.
