0457897881 - ESAB A6 PEK Carriage Beam Assembly

Keep Your A6 Tractor Running Straight

If you are running an ESAB A6 Mastertrac or PEK system, you know that the tractor is the workhorse of your operation. The Carriage Beam (0457897881) is the backbone that keeps your welding head steady and your travel smooth. Over time, heavy use in rough shop environments can take a toll on structural parts. A bent or worn beam can cause your arc to wander or your travel speed to fluctuate, leading to rework that kills your productivity.

This is the genuine ESAB replacement beam, built to fit your machine perfectly without modification. It’s tough, heavy-duty, and ready to handle the heat and weight of sub-arc hoppers and heavy wire spools. Swapping out a damaged beam helps ensure your machine tracks true, keeping your welds straight and your defects low.

Don't compromise your setup with makeshift fixes. This beam gets your automation equipment back to factory specs so you can focus on monitoring the puddle and managing the flux, rather than fighting with the machine's alignment.
