952940 - ESAB 4-Roll Auto Lift Drive Mechanism Assembly

Get Your Feeder Running Like New

If you are fighting with your wire feeder, dealing with slipping wire, bird-nesting, or an arc that stutters and sputters, the problem might not be your settings—it could be your drive mechanism. The ESAB Drive Stand 4R Auto Lift (952940) is the genuine replacement heart for your ESAB wire feeder. This isn't just a spare part; it's an upgrade in convenience and reliability. The "4R" stands for four-roll drive, which is the gold standard for smooth feeding. Unlike 2-roll systems that have to squeeze the wire hard to get a grip (often crushing it in the process), this 4-roll beast grips the wire gently but firmly from top and bottom across two sets of rolls. This means you get consistent feeding without flattening your flux-cored wire or shaving your aluminum wire.

The best feature for the daily welder, however, is the "Auto Lift." We've all struggled with trying to thread a new spool of wire through the feeder while holding up the pressure rolls with one hand and guiding the wire with the other. With the Auto Lift system, as soon as you pop the tension lever to release the pressure, the arms spring up and stay up. It clears the path instantly, letting you slide the new wire right into the liner without fighting the machine. When you're ready, you just snap the tensioners back down, and you're locked and loaded. It turns a frustrating three-handed job into a simple, quick task.

This assembly is built tough to handle the shop environment. It replaces the main block inside your feeder, swapping out worn pivots and tired springs for fresh, factory-spec components. Whether you are running an Aristo Feed or an Origo Feed unit, installing this new drive stand can make an old machine feel brand new. Stop fighting the gun and start welding smoothly again. This kit includes the main stand assembly, ready to bolt in and get you back to burning wire.
