0156106880 - ESAB A6 Motor Tacho Unit 0156106880

Precise Control for ESAB Automation Systems

The ESAB Transducer Unit (Part Number 0156106880) is a critical component designed for the A6-GMC and A6-GMD series of gear motors. In the realm of industrial welding automation, particularly with Submerged Arc Welding (SAW) and heavy-duty MIG/MAG applications, consistency is paramount. This transducer unit serves as the sensory nervous system for your drive motors, providing real-time rotational speed data back to the process controller (such as the ESAB PEK or PEH units).

When operating high-value automation equipment like the ESAB A6 Mastertrac or stationary A6 heads, the wire feed speed and travel speed must remain constant despite fluctuations in load or input voltage. This transducer acts as a tachometer generator, converting mechanical rotation into an electrical signal that the control system uses to adjust power to the motor instantly. By installing this genuine OEM part, you ensure that your system maintains the tight tolerances required for code-quality welds in sectors like shipbuilding, pipe mills, and wind tower fabrication.

Failure of a transducer unit can lead to erratic wire feeding, unstable arcs, or inconsistent travel speeds, all of which compromise weld integrity. The 0156106880 is engineered to meet the original factory specifications of the A6-GMC/GMD motors, ensuring a seamless fit and reliable performance. Investing in genuine ESAB spare parts minimizes downtime and protects the longevity of your capital equipment.

Key Applications

• Submerged Arc Welding (SAW): Maintaining precise deposition rates in heavy plate fabrication.


• GMAW Automation: Ensuring stable arc lengths through accurate wire feed speed control.


• Beam and Pipe Welding: Critical for longitudinal and circumferential welding stations using A6 heads.
