Lincoln S26711 Replacement Knob for Magnum 100SG

Don't Let a Missing Knob Stop Your Aluminum Job

We've all been there: you are in the middle of a rush aluminum repair job, you go to swap out an empty spool of 4043 on your spool gun, and the little black locking knob slips out of your fingers and disappears into the dark abyss under your welding table. Or perhaps years of tightening has finally stripped the threads. Without it, your Magnum 100SG is effectively out of commission. You can't risk taping the cover on and having the spool flop around while you're trying to lay a stack of dimes.

This Replacement Locking Knob is the exact part you need to get your rig back up and running. It is designed to fit your Lincoln Magnum 100SG perfectly, screwing right into the housing to hold that clear plastic cover tight. It keeps your expensive aluminum wire clean and ensures the spool feeds smoothly without binding. The textured grip makes it easy to tighten down by hand, even if you are wearing light TIG gloves or have dirty hands.

Keep a spare in your kit. Spool guns are moved around, bumped, and adjusted constantly. Having this small but crucial part on hand means the difference between finishing the job on time or shutting down to wait for a delivery. It’s a simple, affordable fix that restores the professional reliability of your Lincoln equipment.
