415-30-15 - Tregaskiss 0.030" Steel Liner, 15 ft Length

Restore Smooth Feeding with the Tregaskiss 0.030" Liner

Every welder knows the frustration of a sputtering gun. You check your ground, you check your settings, but the wire just won't feed smoothly. More often than not, the culprit is a dirty or worn-out liner. The Tregaskiss 415-30-15 is the direct replacement liner you need to get back to laying down perfect beads. Designed specifically for 15-foot MIG guns running 0.030" solid steel wire, this liner eliminates the friction and drag that lead to bird-nesting at the drive rolls and erratic arc behavior at the puddle.

Why stick with genuine Tregaskiss parts? Because they are built to last in the toughest shop environments. This liner isn't just a generic spring; it's a precision-wound steel conduit that resists kinking even when you're welding in tight positions with the cable looped. The 15-foot length gives you plenty of material to work with—simply install it into your gun and trim the excess at the front end according to your gun's specific stick-out requirements. A fresh liner means less resistance on your wire feeder motor and a consistent wire speed, which translates directly to better penetration and bead appearance.

Installation is straightforward and should be part of your regular maintenance routine. If you are noticing that your wire is "chattering" or if you see copper dust building up at the back of the gun, it's time for a swap. This liner is optimized for 0.030" wire, providing a snug fit that supports the wire column without gripping it too tightly. Don't let a cheap consumable compromise your expensive welds. Keep a few Tregaskiss 415-30-15 liners in your toolbox so you are always ready to tackle the job with equipment that performs as hard as you do.
