44-116-25 - Tweco Style 44-116-25 Steel Liner 25ft .052-1/16

Precision Engineered 44-116-25 Replacement Liner

Optimize your MIG gun's performance with the Tweco Style 44-116-25 Conduit Liner, a premium replacement part designed for high-amperage welding applications ranging from 300 to 450 amps. This liner is meticulously crafted to meet the rigorous demands of professional welders who rely on consistent wire delivery for structural and heavy-plate fabrication. It is specifically engineered to handle wire diameters of .052 inches (1.3mm) and 1/16 inches (1.6mm), making it a staple for flux-cored and solid wire welding processes that require substantial deposition rates.

The structural integrity of the liner is derived from its steel wound construction. The spring-tempered wire is wound to a precise internal diameter that supports the welding wire without allowing excessive play, which is crucial for maintaining the wire's cast and helix as it exits the contact tip. To further enhance performance, the steel is zinc plated. This plating process not only prevents rust and oxidation inside the cable bundle but also acts as a dry lubricant, significantly reducing friction. Lower friction levels translate to less strain on the wire feeder motor and drive rolls, extending the life of your entire feeding system.

Installation is straightforward and secure, thanks to the brass alloy machined stop located at the back end of the liner. This component is manufactured to tight tolerances to ensure it seats perfectly within the gun's power pin, maintaining the correct liner stick-out and gas seal. This specific liner is compatible with a broad spectrum of industry-standard guns, including the Tweco Spray Master series (MS350, MS450), the Eliminator series (ELC250, ELC350, ELC450), and the Professional Choice #3 and #4 guns. It also serves as a suitable replacement for Magnum 300/400Amp guns that utilize Tweco-style consumables.

At 25 feet in length, this liner provides ample coverage for standard and extended-length gun assemblies. It can be easily trimmed to exact length requirements during installation, ensuring a perfect fit for your specific torch setup. The inclusion of the stamped part number on the brass stop eliminates guesswork during maintenance intervals, ensuring you always install the correct liner for your wire size and gun amperage. Invest in the 44-116-25 liner to ensure your welding operations run smoothly, efficiently, and without interruption.
