0700300469 - ESAB Steel Neck Liner 0.030-0.045 Inch

Restore Your Torch Performance with Genuine ESAB Parts

Keep your MIG welding gun running like new with the ESAB Neck Liner Steel 0.8-1.2mm (0700300469). If you are experiencing erratic wire feeding, sputtering arcs, or increased resistance when welding, the culprit is often a worn or clogged liner in the torch neck. This replacement neck liner is designed to fit specific ESAB MIG guns, providing a fresh, smooth path for your welding wire right where it matters most—at the bend of the torch.

This liner is intended for use with steel welding wires and accommodates a diameter range of 0.8mm to 1.2mm (0.030 inches to 0.045 inches). This covers the most common wire sizes used in automotive repair, DIY projects, and light-to-medium fabrication. The neck liner (sometimes called a jump liner) sits inside the curved "swan neck" of the gun. Because this area experiences the most friction due to the bend, it wears out faster than the main conduit liner. Replacing it is a quick and cost-effective way to solve feeding issues without replacing the entire gun liner.

Don't let a cheap or worn-out part ruin your welds. Using genuine ESAB consumables ensures that your equipment operates within its specified parameters. Installation is straightforward, allowing you to get back to welding in minutes. Whether you are a professional welder or a serious hobbyist, keeping a spare neck liner in your toolbox is a smart move to prevent downtime.
