FL-19 Welding DC Shunt 400A
The FL-19 Welding DC Shunt 400A is an industrial-grade current shunt designed to handle high-load current sensing in arc welding machines and automated welding systems. It provides a stable 75mV output at 400A with ±0.1% standard accuracy, ensuring consistent and reliable signal transmission under demanding working conditions.
Its low resistance value of 0.1875mΩ minimizes heat generation and energy loss, while the manganin core ensures thermal stability and low drift during prolonged welding cycles. The FL-19 400A shunt features a rugged, bolt-on structure with strong arc resistance, ideal for use in environments with electrical surges and rapid current shifts.
It is commonly used in welding current controllers, waveform feedback modules, and industrial welding automation platforms, helping improve weld quality and control precision.
