14401031 - Tweco 43 Series Flux Core Liner 3/32" 15ft

Tweco 1440-1031: Premium 15ft Flux Core Liner

The Tweco 1440-1031, also known by its industry reference 43FC33215, is a specialized conduit liner manufactured by Tweco to support 3/32" (2.4mm) welding wires. This liner is explicitly designated for Flux Core (FC) applications, featuring a robust internal structure designed to accommodate the specific characteristics of tubular wires. Unlike solid wires, flux-cored wires can be softer or have different surface textures that require a liner with the right support and friction coefficients. This 43 Series liner provides that optimized path, ensuring the wire travels smoothly through the 15-foot cable assembly without buckling or dragging.

Key Technical Features:

• Wire Compatibility: 3/32" (2.4mm) diameter.
• Wire Type: Optimized for Flux Core and Metal Core wires.
• Length: 15 feet (4.5 meters), suitable for standard length MIG guns.
• Series: Tweco 43 Series, ensuring compatibility with a wide range of Tweco MIG guns (typically rated 300A and above).

Maintaining the integrity of your MIG gun's liner is crucial for weld quality. Over time, liners accumulate dust, metal shavings, and lubricant residue, which can restrict wire movement. This restriction forces the wire feeder to work harder and can result in an unstable arc or burn-back. The Tweco 43FC33215 is manufactured to tight tolerances to prevent these issues. Its durable coil construction resists kinking and crushing, providing a long service life even in harsh industrial environments. When your welding application demands the high deposition rates of large diameter flux-cored wires, trust this genuine Tweco liner to deliver the wire consistently to the weld pool.

Installation is straightforward for experienced operators. Simply remove the old liner, check the gun length, and trim the new liner to the correct protrusion if necessary (though 15ft is a standard pre-cut length for many assemblies). Ensure your welding equipment performs flawlessly by choosing the correct liner for your wire size and type. The 1440-1031 is the professional's choice for 3/32" flux-cored welding setups.
