Tweco 171380 Wire Feeder Retaining Knob

Keep Your Wire Feeder Running Smoothly

There is nothing more frustrating than a small broken part stopping your entire welding production. The Tweco 171380 Retaining Knob is the direct replacement you need if the original knob on your wire feeder has cracked, stripped, or gone missing. Designed specifically for Tweco and compatible wire feeders, this knob plays a vital role in keeping your wire spool or feeder cover secure while you weld.

In a busy shop, wire feeders take a beating. Knobs get over-tightened, dropped, or simply wear out over time. A loose or broken retaining knob can cause your wire spool to wobble or your drive roll cover to rattle, leading to inconsistent wire feeding, bird-nesting, or even arc instability. Replacing a damaged knob immediately is a cheap and easy fix that prevents these larger headaches down the line.

This replacement part installs in seconds—just screw it into place. The textured grip makes it easy to handle even when you are wearing work gloves. Whether you are swapping out an empty spool or performing a quick clean of your drive rolls, having a reliable retaining knob ensures the process is smooth and efficient. Don't let a loose part compromise your weld quality; keep a spare 171380 knob in your maintenance kit.
