0558005257 - ESAB 400A Current Sensor 15V Replacement Part

Restore Factory Precision with Genuine ESAB Parts

When your industrial welding equipment begins to show signs of erratic behavior, inconsistent arc stability, or inaccurate digital displays, the issue often lies within the internal monitoring components. The ESAB Current Sensor 400AT 15V 5% (SKU: 0558005257) is a critical replacement part designed to bring your ESAB power source back to its original factory specifications. As a genuine OEM component, this sensor is engineered to fit perfectly within compatible ESAB machines, ensuring that the installation process is straightforward and that the part functions exactly as the manufacturer intended.

The current sensor acts as the nervous system of your welding machine's power output. It continuously monitors the amperage being delivered to the arc and sends this data back to the main control board. If this sensor fails or drifts out of tolerance, the machine's logic board receives incorrect data, leading to poor weld quality, spatter, or even safety shutdowns. By choosing this authentic ESAB replacement, you are investing in the longevity of your equipment. Unlike aftermarket generic sensors which may have varying impedance or response times, this unit is calibrated specifically for the 15V control circuits found in ESAB's high-performance welders.

Maintenance professionals understand that downtime is costly. Having the right repair parts on hand, or knowing exactly what to order, is essential for minimizing production interruptions. This sensor is rated for 400 Amps, covering a wide range of medium to heavy-duty welding applications. Its 5% tolerance rating ensures that the feedback loop remains tight and accurate, providing the welder with the confidence that their settings are being delivered to the workpiece. Whether you are repairing a machine in a fabrication shop, a shipyard, or a manufacturing plant, trust in the reliability of genuine ESAB parts to keep your operations running smoothly.

Don't compromise on the internal electronics of your sophisticated power sources. Using the correct current sensor preserves the integrity of the machine's complex algorithms, particularly in inverter-based systems where rapid current changes must be detected instantly. Ensure your fleet operates at peak efficiency with the ESAB 0558005257 Current Sensor.
