198415 - Miller 198415 Head Tube Liner for XR-Aluma-Pro

Restore Smooth Feeding with the Miller 198415 Barrel Liner

If you are experiencing stuttering wire feed or erratic arcs while using your Miller XR-Aluma-Pro, the issue might not be your settings—it could be your neck liner. The Miller 198415 Liner, also known as a Guide Spiral, is the essential replacement part located inside the curved neck of your push-pull gun. This small but mighty component guides your welding wire through the bend of the torch, ensuring it reaches the contact tip without dragging or shaving.

Aluminum welding requires precision, and soft aluminum wire is notorious for getting caught or shaved if the wire path isn't perfect. A worn-out barrel liner creates friction points that disrupt the smooth flow of wire, leading to frustrating downtime and compromised weld quality. By replacing your old liner with this genuine Miller 198415, you restore the factory-fresh performance of your gun, allowing the wire to glide effortlessly through the curve.

Designed specifically for the XR-Aluma-Pro and XR-Pistol-Pro models, this liner is easy to install and is a must-have spare part for any serious fabrication shop. Don't let a simple wear part hold up your production. Keep your push-pull system running at peak efficiency and ensure consistent, high-quality welds by maintaining your gun's head tube with authentic Miller replacement parts.
