Abstract: An example welding torch neck adapter includes: an electrically conductive body configured to detachably attach to a handle assembly of a consumable electrode-fed welding torch on a first portion of the conductive body and configured to detachably attach to a neck of the welding torch on a second portion of the conductive body to secure the neck to the handle assembly; and a guide tube positioned within the conductive body and configured to support a first consumable wire liner in alignment with a liner lock of a second consumable wire liner.

Abstract: An example wire liner retention apparatus includes: a body comprising a bore extending longitudinally through the body, the bore configured to permit passage of a welding wire liner through the bore; a clamp configured to apply a compressive force to the welding wire liner in a radial direction within the bore to limit movement of the welding wire liner with respect to the body; and a compression adjustment mechanism configured to adjust the compressive force applied by the clamp.

Abstract: Apparatus, systems, and/or methods for providing welding systems or portions of welding systems that provide a tip-retention device that is configured to direct gas radially towards a contact tip.

Abstract: A welding torch having a nozzle assembly with multiple attachment methods is disclosed. The nozzle assembly includes a nozzle shell, an electrically insulating sleeve, and a nozzle insert. The nozzle insert is configured for attachment to gas diffuser assemblies with different attachment mechanisms (e.g. a slip-on mechanism relying on frictional force, and/or screw-on mechanism relying on torque).

Abstract: Reversible contact tips and welding assemblies for reversible contact tips are disclosed. An example welding contact tip includes a first axial end portion having a welding wire outlet of an inner bore of the welding contact tip, a threaded middle portion adjacent the first axial end portion, wherein the threaded middle portion comprises external threads configured to mate with internal threads of a gas diffuser of a welding torch, and a second axial end portion adjacent the threaded middle portion.

Abstract: A welding gun neck for a welding gun includes an elongated tubular body having an end connectable to a gas diffuser. The elongated tubular body includes a threaded external surface adjacent the end. The threaded external surface defines a male, threaded portion. The male, threaded portion is mateable with a female thread of the gas diffuser. The threaded external surface includes a straight portion and an adjoining tapered portion. The welding gun neck is connectable to both a gas diffuser having a straight female thread and a gas diffuser having a tapered female thread.

Abstract: A compressible end-fitting for a welding gun liner includes a tubular body. A head is disposed at an end of the tubular body. The head is wider in diameter than the tubular body. A sleeve is disposed around the end portion of the tubular body that includes the head. The sleeve includes a stepped inner surface defining a shoulder. At least one biasing member is disposed between the head and the shoulder. The biasing member(s) urges the head outwardly away from the sleeve. An annular stop on an outer surface of the tubular body is contactable with an edge of the sleeve to limit movement of the head relative to the sleeve. The head is linearly retractable from a resting position into the sleeve by application of an axial force, and the biasing member(s) returns the head to the resting position when the axial force is removed.

Abstract: A removable cooling collar is provided for cooling the nozzle of a welding nozzle. This collar includes first and second parts in fluid communication with a chamber that extends circumferentially within a hollow structure. Cooling fluid circulating through the chamber facilitates dissipation and/or extraction of heat in the nozzle, in turn reducing the likelihood of weld splatter adhesion on the nozzle.

Abstract: A neck for a welding torch includes a rigid, non-tubular, elongated member having opposite first and second ends. The first end is connectable to a rear portion of the welding torch. The second end is connectable to a welding tip portion of the welding torch. The member locates and holds the welding tip portion in a precisely given location, and does not communicate welding power, welding wire, shielding gas, or cooling water between the first and second ends.

Abstract: A welding system having a welding gun. The welding gun is adapted with a trigger. The welding gun may have a lever to lock the trigger in a desired pivoted position. The lever may pivot the trigger as the lever is pivoted. The welding gun may have a trigger extension to enable a user to pivot the trigger by depressing the trigger extension. The trigger extension may be plastically deformed. The trigger extension may be removable. The trigger extension may be rotatable.

Abstract: A welding system having a welding gun with a handle. The handle is adapted to cool the interior of the handle with a flow of air. The handle may be adapted with a plurality of ventilation holes to enable air to pass through the handle. The handle may have a plurality of ribs disposed along the interior of the handle to direct air flow around a conductive member disposed therein. The ribs may be adapted to direct the air to flow radially and/or longitudinally around the interior of the handle.
