OVERVIEW

Smooth Wire Feeding for 25ft MIG Guns

Is your MIG wire stuttering, dragging, or burning back to the tip? The culprit is often a dirty or worn-out liner. Upgrade your setup with the Tweco Style 42-3035-25 Conduit Liner, specifically designed for 25-foot cable assemblies. This liner is the backbone of your wire delivery system, guiding the welding wire from the feeder to the contact tip. When your liner is in top condition, your welds are smoother, spatter is reduced, and frustration is eliminated.

This liner is built tough for the shop. It features a steel wound construction that is zinc-plated to minimize corrosion. Over time, copper dust and shop grime can build up inside a liner, increasing friction and causing feed motors to overwork. The zinc plating on this replacement part helps resist this buildup and ensures your .030" or .035" wire slides through effortlessly. The 25-foot length makes it perfect for extended reach guns used in large fabrication projects, trailer repair, or automotive work where standard 15-foot cables just don't reach.

Installation is straightforward and hassle-free. The liner comes with a brass alloy stop that seats perfectly into Tweco #1, #2, Spray Master MS250, and compatible Magnum 250 guns. The part number is stamped right on the brass fitting, so you'll always know you have the right size for your wire diameter. If the liner is slightly longer than your specific cable setup, it can be easily trimmed to the correct stick-out length following standard liner replacement procedures.

Don't let a cheap or worn-out liner ruin your welds. Feeding issues can lead to poor penetration and ugly beads. Keep a spare 42-3035-25 in your toolbox so you are always ready to swap it out. Compatible with standard mild steel wires, this liner is a cost-effective solution for maintaining your Tweco-style equipment. Get back to welding with confidence and precision.
