210970 - Miller .023-.035 Monocoil Liner 8ft for Hobart H-9A

Smooth Feeding for Better Welds

Is your wire stuttering, dragging, or burning back to the tip? The problem might not be your welder settings—it's often a dirty or kinked liner. The Miller 210970 Monocoil Liner is the direct replacement you need to get your Auto Arc 130 or Hobart H-9A MIG gun running like new again. Designed to handle .023, .030, and .035 solid wires, this liner ensures your wire glides smoothly right to the puddle.

We know that fighting your equipment is the fastest way to ruin a project. A compromised liner adds friction, causing the drive rolls to slip or the wire to birdnest at the feeder. By swapping out your old liner with this fresh 8-foot steel monocoil replacement, you eliminate that friction. The result is a consistent wire speed, a stable arc, and a much more enjoyable welding experience. It’s a small investment that makes a huge difference in bead consistency.

This liner is built tough by Miller, meaning it resists kinking and holds up to the rigors of the shop. At 8 feet long, it is pre-sized for the shorter cable assemblies found on the Auto Arc 130 and Hobart H-9A, so you don't have to worry about buying a universal liner and cutting off 7 feet of waste. Keep a spare in your toolbox so you're never stuck waiting on parts when you should be burning wire.

Why Replace Your Liner?

Think of the liner as the artery of your MIG gun. If it's clogged or damaged, the flow stops. Replacing it is part of standard maintenance, especially if you haven't done it in a while or if you've switched between dirty and clean wires. This simple fix can solve 90% of wire feeding headaches.
