38047 - ESAB 38047 Current Sensing Shunt Board

Restore Precision to Your Welding Equipment

When your welding machine's performance begins to drift, or if you are experiencing erratic arc characteristics, the issue often lies within the internal monitoring components. The ESAB 38047 PCB Shunt Assembly is a critical replacement part designed to restore the heartbeat of your power source. In modern welding equipment, the shunt acts as the primary sensor for amperage output, translating the massive flow of welding current into a readable signal for the control logic.

This assembly combines the heavy-duty resistive element of a shunt with the delicate precision of a printed circuit board (PCB). Over time, electrical components can degrade due to heat cycles, dust ingress, or electrical surges. A failing shunt assembly can lead to inaccurate display readings, unstable arcs, or a complete loss of output regulation. By choosing this genuine ESAB replacement, you are ensuring that your machine receives the exact component it was engineered to use, maintaining the integrity of its original design.

Installation of the 38047 PCB Shunt Assembly is the surest way to bring a compromised machine back to life. Unlike generic aftermarket parts that may have slight variances in resistance or signal calibration, this OEM part guarantees that the feedback loop to your welder's main processor is accurate. This accuracy is vital for processes that require tight adherence to welding procedure specifications (WPS). Whether you are repairing a machine for a production line or a job shop, trusting genuine ESAB parts protects your investment and ensures consistent weld quality.

Don't let a small component compromise the capability of your industrial equipment. The ESAB 38047 is built to the high standards expected from a world leader in welding technology. It integrates seamlessly with compatible ESAB power sources, ensuring that the complex relationship between voltage, amperage, and wire feed speed is maintained perfectly. Keep your operations running smoothly and your welds passing inspection with this essential repair component.
