OVERVIEW

Genuine Lincoln Electric T14813 Thumb Screw for Wire Feeders

Maintain the integrity and performance of your Lincoln Electric welding equipment with the genuine T14813 Thumb Screw. This essential replacement part is designed to secure the MIG gun backend into the wire drive assembly of your welder. Over time, small components like thumb screws can be lost during maintenance or stripped due to frequent adjustments. The T14813 is the exact OEM specification required to ensure your welding gun remains firmly seated, which is critical for maintaining a consistent electrical connection and proper shielding gas flow.

The Lincoln T14813 features a durable, knurled plastic head molded onto a steel threaded stud. This design allows for easy hand-tightening, eliminating the need for screwdrivers or wrenches when swapping out guns or performing liner maintenance. A secure gun connection is vital for the smooth operation of the wire feeding system; a loose gun can lead to wire bird-nesting, erratic arcs, or gas leakage at the drive roll interface. By using genuine Lincoln Electric parts, you ensure perfect compatibility with your machine's specific tolerances.

This thumb screw is compatible with a broad array of Lincoln Electric compact wire welders, including popular models in the SP-series, Weld-Pak series, and Pro-MIG series. Whether you are a professional fabricator maintaining a fleet of machines or a hobbyist keeping your garage welder in top shape, having a spare T14813 on hand prevents downtime caused by a simple missing part. Trust Josef Gas to supply authentic Lincoln Electric components that restore your equipment to factory standards.

FAQ

The T14813 thumb screw is used to secure the MIG welding gun into the wire drive assembly of the welder, ensuring it stays in place for proper electrical contact and wire feeding.

It fits a wide variety of compact Lincoln welders, including the SP-series (SP-135, SP-175), Weld-Pak series, Pro-MIG series, and many others that use a similar wire drive casting.

No, the T14813 features a knurled plastic head designed for hand-tightening, allowing for tool-free adjustments.

Yes, this is the genuine OEM Lincoln Electric part number T14813 (or T14813-B).

If the screw is loose or missing, the MIG gun can slip out of the drive assembly, causing wire feed issues, loss of shielding gas coverage, or a break in the welding arc.

While the thread might match, a standard bolt requires tools to remove and may not have the correct length or tip profile to secure the gun without damaging the brass backend. The OEM thumb screw is recommended.

Typically, the T14813 is sold as the screw unit itself. Some assemblies may use a washer, but the screw is the primary retention device.
