OVERVIEW

Keep Your Dura-Flux Running with Bernard QJL-564 Jump Liners

When you are burning heavy wire on the job site, the last thing you need is a bird's nest or a stuttering feed caused by a worn-out liner. The Bernard QJL-564 Jump Liner is your go-to solution for keeping your Bernard Dura-Flux guns operating at peak performance. Designed specifically for running 5/64-inch flux-cored wire, these liners are built to handle the heat and abuse of gasless welding. Whether you are welding structural beams or repairing heavy machinery, a smooth wire feed is the key to a solid bead, and it starts with a fresh liner.

The beauty of the jump liner system is the time it saves you. We all know the neck of the gun takes the most punishment. The wire bends, the heat builds up, and the liner wears out there first. Instead of pulling the entire liner out of the cable assembly—which can be a hassle, especially with long leads—you simply pop off the neck and swap out the QJL-564 jump liner. It takes minutes instead of half an hour, getting you back under the hood faster. This pack contains 10 liners, so you can toss a few in your toolbox and keep the rest in the supply cabinet.

These liners are made from durable steel that resists kinking and crushing. They are designed to reduce friction, allowing that heavy 5/64" wire to slide through easily without dragging. This reduces strain on your wire feeder drive rolls and helps prevent burn-back. If you are running a Bernard Dura-Flux gun for self-shielded work, these are the OEM replacements you can trust to fit perfectly every time. Don't let a cheap or worn-out liner ruin your welds; stick with genuine Bernard parts for reliability you can count on.

  • Perfect Fit: Designed exclusively for Bernard Dura-Flux guns.
  • Heavy Duty: Built to handle 5/64" self-shielded wire.
  • Value Pack: Comes with 10 liners to keep you stocked up.

FAQ

The QJL-564 is designed specifically for 5/64-inch (approx. 2.0 mm) welding wire.

This liner is designated as 'Gasless', meaning it is optimized for self-shielded flux-cored applications, typically used with Bernard Dura-Flux guns.

A jump liner allows for the replacement of the liner section in the gun neck—where the most wear occurs—without needing to replace the entire gun liner, saving time and material costs.

This product is a package of 10 jump liners.

It is designed for use with Bernard Dura-Flux series welding guns.

It is not recommended. Using a liner significantly larger than the wire diameter can cause poor electrical contact and erratic wire feeding. You should use a liner matched to your wire size.

Yes, the QJL-564 is a genuine Bernard product.

It is made from durable coiled steel suitable for heavy-duty flux-cored wires.
