14501155 - Tweco 1450-1155 MIG Gun Liner 15ft .035-1/16 Wire

Optimize Your MIG Gun Performance

Keep your welding arc smooth and consistent with the Tweco 1450-1155 MIG Gun Conduit Liner. As any experienced welder knows, the condition of your liner directly impacts the quality of your weld. A worn, kinked, or dirty liner creates drag on the welding wire, leading to slipping drive rolls, fluctuating amperage, and frustrating burn-backs. This genuine Tweco replacement part restores the smooth, low-friction path your wire needs to travel effortlessly from the feeder to the weld pool.

Key Specifications:

• Part Number: 1450-1155 (Model 44-3545-15)
• Length: 15 feet (4.5 meters)
• Wire Compatibility: .035" to 1/16" (0.9mm - 1.6mm)
• Material: Zinc-plated spring steel wound

This liner is designed for versatility, accommodating a popular range of wire diameters used in structural steel, manufacturing, and maintenance applications. The wound steel construction provides the necessary flexibility to navigate the bends of the MIG gun cable without collapsing, ensuring the wire diameter is not constricted. It is specifically sized for 15-foot cable assemblies but can easily be trimmed for shorter guns if necessary, making it a versatile addition to your shop's spare parts inventory.

Compatibility is key with MIG consumables. The 1450-1155 fits a wide array of Tweco guns, including the industry-standard Spray Master series and the rugged Classic series. When installing, ensure the liner is cut properly to fit flush against the gas diffuser or retaining head, as gaps can cause erratic feeding. By choosing genuine ESAB/Tweco parts, you are investing in longevity and performance, minimizing the frequency of liner changes and maximizing your arc-on time.
