193146 - Miller 193146 Monocoil Neck Liner 1/16-1/8 Wire

Smooth Feeding for Heavy-Duty Welding

When you are pushing heavy wire, every inch of your liner path matters. The Miller 193146 Monocoil Liner is the unsung hero of your MIG gun's front end. Designed specifically for the business end of your torch—the neck—this 8.125-inch liner bridges the gap where your wire undergoes the most stress. If you are running 1/16-inch to 1/8-inch wire, you know that friction is the enemy. A worn or clogged neck liner can cause your wire to drag, leading to an unstable arc, excessive spatter, and the dreaded burnback that stops production cold.

This liner is built tough with monocoil construction. Think of it as a flexible steel tunnel that guides your wire through the bend of the torch without collapsing or binding. It is designed to handle the heat and the physical wear of heavy industrial welding. Because it sits right behind the contact tip and diffuser, this short section of liner takes a beating from reflected heat and micro-arcing. Replacing it is often a quick fix that solves mysterious feeding problems that a new contact tip alone won't cure.

Don't compromise your weld quality with generic fit-ups. This genuine Miller part ensures that your wire stays centered and moves freely, allowing you to focus on the puddle rather than fighting the feeder. Whether you are fabricating heavy structural steel or performing maintenance repairs, keeping a fresh neck liner in your kit is smart practice. It installs easily into compatible Miller guns, restoring that 'like-new' smooth feeding feeling immediately. Ensure your setup is rated for the heavy wire sizes (up to 1/8 inch) this liner supports, and get back to laying down perfect beads.
