Bronze MIG Torch Neck Liner – 0.6–1.2mm

A bronze liner keeps steel and stainless MIG wire feeding smoothly through the torch neck — the wrong liner material or size causes birdnesting, feed stutter, and burnback at the contact tip.

Key specs

- Bronze wire liner, 0.6–1.2mm wire range
- Fits the torch neck feed path — confirm your torch model and neck length before ordering, since liner length varies by torch

Why bronze instead of steel?

Bronze liners run cooler and with less friction than coiled steel, which suits softer wires and lighter-duty feeding. For hard, high-tensile steel wire under heavy feed pressure, a steel liner holds up better — match the liner material to your wire type, not just the diameter.

MIG liner FAQ

How often should I replace a torch liner?

Replace it once you notice feed stutter, wire birdnesting at the drive rolls, or a rough, inconsistent arc — worn liners narrow and roughen internally long before they visibly fail.

Does liner length matter?

Yes — a liner cut too long kinks inside the neck, and one cut too short won't reach the contact tip. Trim to the torch manufacturer's spec, not by eye.
