The disclosure includes a welding cup system comprising a tube having an open top, an open bottom, a sidewall extending between the open top and the open bottom, and an open channel. The open channel may extend through an interior portion of the tube from the open top to the open bottom. The open top may be arranged and configured to slideably couple to at least a portion of a torch assembly. The open channel may be arranged and configured to allow gas to flow from the open top to the open bottom, and allow a welding electrode to extend through the open channel from open top towards the open bottom. The welding cup system may have a side profile that may define an asymmetrical shape.

A welding system includes a gas line coupled to components of the welding system and a first gas line transducer coupled to the gas line. The gas line is configured to convey a gas between components of the welding system. The first gas line transducer is configured to communicate via radio signals transmitted through the gas line.

A method of controlling a back weld root surface includes arranging a sealing portion along the back weld root surface of a workpiece to form a purge region adjacent to a section of a joint, supplying a shielding gas within the purge region at a first flow rate, and applying a weld deposit across a front surface of the section of the joint. The shielding gas displaces an ambient environment within the purge region, and the back weld root surface of the weld deposit includes a positive root penetration relative to the back weld root surface based at least in part on the shielding gas within the purge region.

Systems and apparatus are disclosed relating to smart regulators and smart manifolds for welding-type systems. A smart regulator may be coupled to a fluid tank and provide information regarding the current pressure(s) and/or flow rate to a remote device and/or operator. The remote device may also determine and/or output additional information, such as, for example, remaining fluid and/or remaining time before the fluid runs out or becomes dangerously low. A smart manifold may be configured to work with several different fluid supplies. In this way, an operator may easily mix fluid types, switch between different fluid types, and/or switch between different fluid tanks.

An extractor system includes a negative pressure gas stream source, a negative pressure conduit, a housing, a positive pressure gas stream source, a positive pressure gas stream manifold, and an operator interface. The negative pressure conduit conveys the negative pressure gas stream from a work area. A first end of the negative pressure conduit is coupled to the negative pressure gas stream source, such that the negative pressure gas stream flows from the work area through a second end of the negative pressure conduit and toward the first end of the negative pressure conduit. The housing is disposed about the negative pressure conduit, near the second end of the negative pressure conduit comprising. The positive pressure gas stream source is coupled to the housing. The positive pressure gas stream manifold is located downstream of the positive pressure gas stream source. The positive pressure gas stream is directed through the positive pressure gas stream manifold. The operator interface allows a user to control the positive pressure gas stream through the positive pressure gas stream manifold.

Provided is a disclosure for a ventilation conduit for a welding torch, where the ventilation conduit comprises a conduit body comprising at least a first part and a second part, and a conduit nozzle. The first part and the second part are configured to be removably coupled to each other around an outside of a welding torch. The conduit nozzle, with a first end that is beveled and a second end, is configured to be removably coupled by the second end to the conduit body.

A welding shield that is configured to provide improved gas distribution adjacent a weld seam during the welding process so as to improve the weld quality. The welding shield includes a central member wherein the central member includes contiguously formed sidewalls and a top wall operable to create an interior volume. Mounted within the interior volume is a gas distribution module that is operably coupled to a gas source. A clip member is mounted to the central member and is configured to provide retention of the gas distribution module. A torch retention member is movably mounted to the top wall of the central member. The torch retention member is configured to receive and secure a welding torch and further provide rotational and pivotal movement thereof. A plasma cutter holding member is further included and is operable to releasably retain a plasma cutter.

A welding or additive manufacturing power supply includes a user interface that receives a user input shielding gas mixture comprising separately adjustable amounts of a first and a second shielding gas. Output circuitry generates a shielding gas customized welding waveform. A memory stores a first plurality of waveform parameters that are associated with the first shielding gas, and a second plurality of waveform parameters that are associated with the second shielding gas. A controller is operatively connected to control operations of the output circuitry, and is configured to determine a third plurality of waveform parameters at least partially defining the shielding gas customized welding waveform. The controller determines the third plurality of waveform parameters from the first and second plurality of waveform parameters and the amounts of the first and second shielding gas.

An end assembly for use with a welding device having a contact tip, a diffusor body, and a gooseneck. The contact tip has a convex end surface that contacts and mates with a concave end of the diffuser body. The diffuser body forms a blind bore forming central web and a series of passageways. A longitudinal passageway segment is formed in the contact tip parallel with the central longitudinal electrode bore of the contact tip. A second passageway segment joins the first longitudinal passageway segment. When the contact tip is affixed to the diffuser body, a chamber is formed at the base of the contact tip communicating with the diffuser body passageways. Shielding gas that flows into the diffuser body passes through the web passageways into the chamber and through the first and second passageways of the contact tip to provide shielding gas to the weld site and cool the contact tip during welding operations.
