OVERVIEW

Reliable Wire Feeding with Tweco 1440-1105 Conduit

The Tweco 1440-1105 (also known as 44-3545-25) is a premium standard conduit liner designed to maintain the efficiency and reliability of your MIG welding operations. Manufactured by Tweco, a leader in welding gun technology, this liner is engineered to guide welding wire smoothly from the feeder to the contact tip, minimizing friction and preventing common feeding issues such as bird-nesting or erratic arc stability.

This specific liner is constructed from high-quality zinc-plated spring steel. The zinc plating serves a dual purpose: it significantly reduces the coefficient of friction between the liner and the welding wire, and it provides essential protection against corrosion and rust, which can accumulate inside the cable assembly over time. Designed for use with mild steel and flux-cored wires ranging from .035" to .045" (0.9mm to 1.2mm), it is a versatile component for many fabrication environments.

With a total length of 25 feet (7.6 meters), this conduit is suitable for extended reach cable assemblies. It can be easily measured and trimmed to fit shorter guns, making it a flexible stock item for maintenance teams. It is compatible with Tweco 44 Series systems, fitting popular gun models like the Spray Master series and the Classic Number 3, 4, and 5 guns. Regular replacement of your conduit liner is a critical maintenance step that ensures your welding parameters remain consistent and your welds high-quality.

FAQ

This liner is designed for welding wire diameters between .035" and .045" (0.9mm - 1.2mm).

The conduit is 25 feet (7.6 meters) long. It is intended to be trimmed to the exact length of your specific MIG gun cable.

No, this is a steel wound liner. For aluminum wire, you should use a polymer or Teflon liner to prevent shaving the soft aluminum wire.

It fits Tweco guns that use 44 Series liners, including the Classic No. 3, No. 4, No. 5, and the Spray Master 350 and 450 series.

Insert the liner into the gun from the back end until it seats against the diffuser/head, then mark and trim the excess length at the back end according to your gun's manual.

The zinc plating reduces friction for smoother wire feeding and provides corrosion resistance to extend the life of the liner.

Yes, this is a genuine Tweco 1440-1105 (44-3545-25) replacement part.

The '44' indicates the series of the conduit, which determines the outer diameter and compatibility with specific Tweco gun connector blocks.
