M1437 - Miller Phosphor Bronze Liner .030-1/16 for Soft Wire Welding

Smooth Feeding for Aluminum Welding with Miller M1437

Every welder knows the frustration of trying to push aluminum wire through a standard steel liner. The friction builds up, the wire drags, and before you know it, you're dealing with a birdnest at the feeder or an erratic, sputtering arc. The Miller M1437 Phosphor Bronze Liner is the solution designed to eliminate these headaches. Built specifically for soft wires like aluminum and silicon bronze, this liner provides a silky-smooth path for your filler metal, ensuring that what comes out of the contact tip is steady and reliable.

The secret lies in the phosphor bronze material. It is naturally slicker and softer than steel, which means it won't shave off tiny particles of aluminum as the wire travels through the gun. Those shavings are notorious for clogging up liners and causing downtime. By switching to the M1437, you are protecting your wire from damage and ensuring consistent feeding speeds, which is absolutely critical for achieving those stack-of-dimes aluminum welds. It handles a broad range of wire sizes from .030" all the way up to 1/16", giving you the flexibility to tackle different material thicknesses without constantly swapping out gun parts.

This liner is built "Heavy Duty," meaning it resists kinking and crushing better than standard economy liners. Whether you are running a push-pull system or a standard setup optimized for soft wire, this liner helps maintain the rigidity needed to push wire effectively while keeping friction to an absolute minimum. It is often used as a neck liner or in specific gun assemblies where the wire needs that extra bit of care as it makes the turn toward the puddle.

Don't let feed problems ruin your workflow or your weld quality. If you are welding aluminum, you need the right tools for the job. The Miller M1437 is an affordable upgrade that pays for itself by reducing downtime and frustration. Keep your arc smooth, your puddle clean, and your wire feeding freely with this genuine Miller phosphor bronze liner.
