0449485880 - ESAB A6T Drive Motor with Tachometer and Gearbox

Restore Precision to Your ESAB A6T System

The ESAB Motor W Gear (Tacho) A6T (Part Number: 0449485880) is a critical replacement component designed specifically for the heavy-duty ESAB A6 series of automatic welding heads and tractors. In the world of industrial automation, particularly in Submerged Arc Welding (SAW) and high-productivity MIG/MAG applications, the consistency of wire feed speed and travel speed is paramount. This motor assembly is engineered to deliver the torque and precision required to maintain these parameters within tight tolerances.

What sets this motor apart is the integrated tachometer generator. In ESAB's sophisticated process controllers (such as the PEK or PEH), the tachometer provides real-time feedback on the motor's actual speed. This allows the control system to instantly adjust voltage and current to the motor to compensate for load variations, ensuring that the welding wire is fed at the exact rate programmed, or that the tractor travels at a perfectly constant velocity. Without a functioning tacho-feedback motor, automated welds can suffer from irregularities, leading to costly rework or defects.

This assembly comes complete with the necessary gearing to interface directly with the A6T drive mechanisms. The gearbox is constructed to withstand the mechanical stresses of pulling heavy wires or moving substantial welding heads. By choosing this genuine OEM part, you ensure seamless compatibility with your existing equipment, avoiding the mounting issues or electrical mismatches often associated with generic replacements. It is the ideal solution for maintenance teams looking to overhaul aging A6T heads or repair units that have suffered motor failure due to long-term wear.
