FL-19 Welding DC Shunt 500A
The FL-19 Welding DC Shunt 500A is designed for precision current measurement in heavy-duty welding systems, providing stable 75mV output with ±0.1% accuracy at 500A. Its low resistance of 0.15mΩ ensures high efficiency and minimal thermal loss during prolonged welding operation.
Made with a robust manganin resistive core and reinforced copper/brass terminals, this shunt withstands intense current surges, high temperatures, and mechanical stress—making it perfect for inverter-based welders, robotic welding stations, and automated welding platforms.
It delivers rapid response and consistent performance for current control loops, arc stabilization circuits, and welding quality monitoring. Optional upgrades include enhanced accuracy, custom mounting brackets, or modified output voltages based on specific OEM needs.
