0191074123 - ESAB 1000 Amp 60mV DC Shunt Resistor

Genuine ESAB Replacement Shunt for Industrial Power Sources

The ESAB 0191074123 is a high-precision DC current shunt designed to meet the rigorous demands of industrial welding environments. Rated for 1000 Amperes with a standard voltage drop of 60 millivolts (mV), this component is critical for the accurate monitoring and control of welding output. In sophisticated power sources, the shunt acts as the primary feedback mechanism, translating high-current output into a low-voltage signal that control boards and digital meters can interpret. Maintaining the integrity of this signal is essential for process consistency, making this OEM-quality replacement a vital component for equipment maintenance and repair.

Constructed using the PEI-A2 form factor, this shunt features a robust design suitable for heavy-duty applications. The resistive element is typically crafted from manganin, an alloy chosen for its exceptionally low temperature coefficient of resistance. This ensures that the voltage drop remains proportional to the current even as the component heats up during extended welding cycles. The large copper terminal blocks provide low-resistance connection points for the main power cables, while the smaller sensing screws allow for precise voltage pickup for metering instrumentation. This specific configuration ensures compatibility with a wide range of ESAB welding machines and other industrial DC power systems requiring 1000A/60mV specifications.

When servicing welding equipment, replacing a damaged or drifted shunt is often necessary to restore calibration accuracy. A shunt that has been overheated or physically damaged may provide incorrect feedback, leading to erratic arc performance or inaccurate display readings. The ESAB 0191074123 offers a direct-fit solution for technicians looking to maintain factory specifications. Its durable construction resists the vibration and thermal cycling common in workshop environments, ensuring long-term reliability. Whether you are rebuilding a power source or performing routine maintenance on a fleet of heavy industrial welders, this component delivers the precision and durability required for professional results.
