993823 - ESAB ST-16 Replacement Liner .045-1/16

Restore Smooth Feeding with the ESAB ST-16 Liner

Is your MIG gun sputtering, stuttering, or feeling like it's fighting you every inch of the weld? Before you blame the machine or the drive rolls, check your liner. The liner is the unsung hero of your MIG setup, and when it gets clogged or worn out, your entire day can grind to a halt. The ESAB 993823 is the genuine replacement liner you need if you are running an ST-16 MIG gun with .045" or 1/16" wire. It’s designed to get you back to laying down smooth, consistent beads without the headache of erratic wire feeding.

Over time, copper dust from the wire, shop dirt, and general grime build up inside your liner. This creates friction. When the friction gets too high, your wire feeder struggles to push the wire through the cable, resulting in an unstable arc, burn-backs into the tip, or the dreaded "bird nest" of tangled wire at the feeder. Installing a fresh ESAB 993823 liner eliminates this drag. The steel coil construction is tough enough to handle the abrasion of heavy flux-cored or solid wires while remaining flexible enough to let you maneuver the gun into tight positions without pinching the wire flow.

Installation Tips for Welders:
Replacing a liner is a quick maintenance task that pays huge dividends. When installing this liner, ensure you lay your MIG gun cable out completely straight on the floor. This ensures you get an accurate measurement when trimming the new liner to fit. A liner that is cut too short will cause gas leakage or wire chatter inside the diffuser, while one cut too long can cause kinking. Always use a sharp pair of side cutters or a dedicated liner cutter to ensure the end of the coil is clean and free of burrs that could shave the wire.

This specific liner is optimized for the medium-to-heavy wire range (.045 to 1/16 inch). If you are switching your setup from lighter sheet metal work to heavier structural welding, you must change your liner to match the wire size. Trying to push .045 wire through a .035 liner is impossible, and running it through a liner meant for much larger wire leads to a wandering arc. Stick with the ESAB 993823 for a perfect fit in your ST-16 gun and enjoy the difference a fresh consumable makes in your weld quality.
