870082 - Tweco Plastic Wire Feed Knob 1/4-20 Thread

Don't Let a Broken Knob Slow You Down

We've all been there: you're in the middle of a critical weld, you go to swap a spool or adjust your feeder, and a plastic knob snaps off in your hand. It's a small part, but without it, your machine might be out of commission. The Tweco 870082 Plastic Wire Feed Knob is the exact replacement you need to get back up and running fast. Designed specifically for Tweco and compatible wire feeders, this knob features the standard 1/4-20 thread that fits perfectly onto your machine's existing hardware.

Why settle for a makeshift fix with a random nut and washer when you can have the factory-correct part? This knob is built from durable, heavy-duty plastic that stands up to the heat and abuse of the shop floor. It is designed with a textured or shaped profile that makes it easy to grip and turn, even when you are wearing thick welding gloves. This ergonomic advantage means you can make quick adjustments or changes without fumbling for tools or taking your gloves off, keeping your workflow smooth and efficient.

This knob is commonly used on wire feed assemblies, often holding covers in place or acting as a tensioner adjustment point. Because it is plastic, it won't rust or seize onto the bolt like metal wingnuts sometimes do, ensuring that you can always remove it when necessary. It's one of those essential spare parts that every welder should have in their kit or parts bin. A broken knob shouldn't ruin your day—keep a Tweco 870082 on hand and ensure your equipment remains professional and fully functional.

Installation is as simple as it gets: just screw it on. The 1/4-20 thread is a common size, but the specific shape and material of this Tweco knob are tailored for your welder. Restore your machine to its original condition and stop struggling with broken or missing hardware. Grab a few spares today and keep your focus on the arc, not the parts.
