19166 - ESAB ST-23A MIG Liner for .030-.035 Wire

Fix Feeding Issues Fast with the ESAB 19166 Liner

Is your MIG gun sputtering? Are you experiencing burn-back or erratic wire feeding that ruins your bead profile? Often, the culprit isn't your machine or your technique—it's a dirty or worn-out liner. The ESAB 19166 Liner is the direct replacement solution for ST-23A MIG guns running .030" or .035" wire. Think of the liner as the artery of your welding system; if it's clogged or damaged, the entire process suffers. Replacing your liner is one of the most cost-effective maintenance tasks you can perform to instantly restore your welder's performance.

Designed for the rigors of the shop, this steel liner is built to handle the friction of solid steel wires day in and day out. When a liner gets old, it accumulates dust and metal shavings that act like sandpaper against your welding wire, causing drag that leads to slipping drive rolls and inconsistent arc starts. By swapping in a new ESAB 19166, you ensure that your wire glides smoothly from the feeder to the tip, giving you that satisfying, consistent "bacon-frying" sound that every welder loves to hear.

Don't let a cheap or worn-out part slow down your production. This liner is ready to install right out of the package. It is sized specifically for the popular .030 and .035 wire diameters, making it a versatile part to keep in your maintenance kit. Whether you are a professional fabricator or a serious hobbyist using an ESAB setup, keeping a spare liner on hand means you never have to stop work for long when feeding issues arise. Get the reliability of genuine ESAB parts and keep your arcs smooth and steady.
