690514 - ESAB Steel MIG Liner for 0.045-1/16 Wire

Keep Your Wire Running Smoothly with the ESAB 690514 Liner

There is nothing more frustrating for a welder than a gun that won't feed right. You check your drive rolls, you check your contact tip, but the wire still stutters, burns back, or bird-nests at the feeder. More often than not, the culprit is a dirty or worn-out liner. The ESAB 690514 Liner Spring is the direct replacement you need to get your ESAB MIG gun back to welding like new. Designed to handle heavier wire sizes from 0.045" up to 1/16", this steel liner is built tough to withstand the rigors of daily fabrication work.

Think of the liner as the highway for your welding wire. If that highway is full of potholes (kinks) or debris (metal shavings and shop dust), traffic jams are inevitable. A fresh 690514 liner clears the path, allowing the wire to slide through the cable with minimal resistance. This means your wire feeder doesn't have to work as hard, and your arc remains steady and consistent. This liner is made from durable spring steel, which gives it the flexibility to bend as you move around your workpiece without pinching the wire inside. It is the ideal choice for running standard solid steel MIG wire or flux-cored wires in structural and heavy manufacturing jobs.

Replacing your liner is a standard maintenance task that should be done regularly, not just when things break. If you are noticing drag or erratic feeding, it's time to swap it out. Installation is straightforward: remove the old liner, lay the new one out next to the gun cable to measure, and trim it to the correct length according to your gun's manual. Don't let a $20 part cost you hours of downtime and frustration. Keep a spare ESAB 690514 in your toolbox so you are always ready to tackle the job with a smooth, reliable arc.
