20468 - ESAB ST-21 MIG Gun Outlet Wire Guide

Keep Your ST-21 Feeding Smoothly

There is nothing more frustrating than a MIG gun that won't feed right. You pull the trigger, and the wire stutters, burns back, or bird-nests at the drive rolls. Before you blame the liner or the machine settings, check your wire guide. The ESAB 20468 ST-21 Wire Guide is the direct replacement for the outlet guide on your trusty ST-21, ST-16, or ST-22 MIG gun. It’s the small piece that makes a big difference in how your torch handles.

This guide sits at the back of the gun, helping funnel the wire from the machine into the liner. When it gets worn out, it develops grooves that add drag to the wire. That drag messes with your wire speed consistency, leading to an unstable arc and spatter. If you've been fighting your feed, swapping this out is a quick, inexpensive fix that can make your gun feel brand new again. It’s designed to fit perfectly into the handle of your ESAB torch without any modification.

Don't let a cheap worn-out part ruin your welds or your day. Keep a spare 20468 in your toolbox. It installs in minutes and ensures that your wire glides smoothly into the liner, protecting your wire from shaving and ensuring you get that consistent sizzle you're looking for. whether you are running mild steel, stainless, or aluminum, a clean path for the wire is the first step to a perfect bead.

Practical Application Notes

• Inspection: Check this guide whenever you change your liner. If you see a keyhole shape wearing into it, it's time to toss it.
• Installation: Ensure the guide is seated fully before tightening the gun connection to prevent misalignment.
• Compatibility: Works with the classic L-Tec/ESAB ST-21 style handles found in many heavy-duty shops.
