0334332004 - ESAB A6 Welding Head Ball Screw and Nut Assembly L396

Restore Smooth Adjustments to Your A6 Head

If you are running an ESAB A6 automatic welder—whether it's on a tractor, a beam, or a column and boom—you know that smooth torch adjustment is everything. When you turn the knob or hit the switch to move the head up or down, you expect it to move instantly and precisely. The ESAB 0334332004 Ball Screw / Nut L396 A6 is the replacement part you need when that movement starts getting sloppy, gritty, or stuck.

The A6 system is a workhorse, but the moving parts take a beating. Flux dust and grinding grit can eventually work their way into the slide mechanisms. When the ball screw wears out, you might notice "slop" where the motor turns but the head doesn't move right away, or "tight spots" where the motor struggles to push the torch. This can lead to inconsistent welds because the head can't track the seam or maintain the arc length properly. This genuine ESAB kit replaces the entire screw and nut assembly, which is the heart of that sliding motion.

Installing this factory-original part brings your equipment back to like-new performance. It is built to handle the weight of heavy sub-arc torches and the heat of the job. Don't waste time fighting with a binding slide or trying to compensate for a loose head. Swapping out the old screw for this new 0334332004 assembly ensures your automated setups run smoothly, letting you focus on the weld parameters rather than fighting the machine mechanics. Keep your A6 running at peak efficiency with the right parts.
