OVERVIEW

Reliable Wire Feeding with Tweco 35-40-15 Conduit

The Tweco 35-40-15 Conduit Liner is an essential component for maintaining the performance of your MIG welding setup. Designed specifically for welding wires ranging from .030" to .035" (0.8mm - 0.9mm), this liner ensures that your filler metal is delivered smoothly from the feeder to the contact tip. A worn or kinked liner is one of the most common causes of feeding issues, erratic arcs, and frustration on the shop floor. By replacing your old liner with this genuine Tweco part (Stock No. 1400-1133), you can restore the consistency and reliability of your welds.

Constructed from high-quality zinc-plated spring steel, this conduit is built to withstand the rigors of industrial environments. The zinc plating acts as a lubricant to minimize friction drag on the wire, while also providing a layer of protection against corrosion. This is particularly important in shop environments where humidity or storage conditions might otherwise lead to rust on bare steel liners. With a total length of 15 feet, it is sized to fit standard 15ft MIG gun cable assemblies, though it can easily be trimmed to fit shorter cables if necessary.

This liner is part of the Tweco 35 Series and is compatible with a wide range of MIG guns, including the popular Tweco No. 1, No. 2, and Mini-MIG series. Whether you are working on automotive repairs, light fabrication, or general maintenance, ensuring your wire path is clear and smooth is critical. The Tweco 35-40-15 provides the durability and precision needed to keep your downtime low and your weld quality high. Don't let a $20 part ruin a day's worth of welding; keep your equipment in top shape with genuine Tweco consumables.
