636655 - ESAB 636655 Inlet Wire Guide for ST-23A Feeder

Keep Your ST-23A Feeder Running Smoothly

If you are running a classic ST-23A wire feeder, you know it is a workhorse of the industry. However, even the toughest machines need maintenance to keep the arc smooth. The ESAB 636655 Inlet Wire Guide is the small but mighty part that stands between a perfect weld and a frustrating afternoon of clearing birdnests. This guide is the first contact point for your wire as it enters the feeder mechanism, and its job is to make sure that wire hits the drive rolls dead center every time.

Have you noticed your wire stuttering, or found metal shavings accumulating inside your feeder case? These are classic signs of a worn inlet guide. As thousands of pounds of wire pass through the guide, it eventually cuts a groove into the metal. Once that groove forms, it adds drag to the system, forcing your motor to work harder and causing the wire to slip. In worse cases, a worn guide allows the wire to wander off the drive roll groove, leading to crushed wire and immediate feeding failure. Replacing this inexpensive part is one of the easiest ways to troubleshoot erratic feeding issues.

Don't settle for makeshift fixes or generic parts that don't fit quite right. This is the genuine article, designed to fit the specific geometry of the ST-23A. Installation is quick and simple, getting you back under the hood and welding in minutes. Whether you are pushing mild steel solid wire or running heavy flux-cored wire, a fresh inlet guide ensures that your parameters stay consistent and your bead stays straight. Keep a spare in your maintenance kit and ensure your legacy equipment continues to perform like new.

Why Replace Your Inlet Guide?

• Prevent Shavings: Worn guides scrape wire, clogging liners.
• Stop Slippage: Reduces drag for consistent wire speed.
• Protect Drive Rolls: Ensures wire stays in the groove.
• Arc Stability: Consistent feeding means a consistent arc.
