The Multiquip 1971880003 AC Reactor is a genuine OEM component designed for the GLW-180H welder. Sourced directly from Multiquip, this part meets the original engineering specifications for the GLW-180H, ensuring proper electrical performance and circuit protection. If your GLW-180H is experiencing unstable output or electrical irregularities, the AC Reactor is a key component to inspect and replace with a verified OEM part.
Key Features
- OEM-Grade Inductance Rating — Built to the original electrical specification of the GLW-180H, ensuring the reactor delivers the correct impedance and current-smoothing performance the circuit depends on.
- Direct-Fit Installation — Engineered as a drop-in replacement for the GLW-180H, matching the original mounting configuration and wiring connections for a straightforward swap.
- GLW-180H Fitment Confirmed — Verified for compatibility with the Multiquip GLW-180H welder series, so you can order with confidence.
- Stable Arc and Output Quality — A correctly functioning AC Reactor suppresses voltage spikes and smooths current flow, supporting consistent weld arc performance and protecting sensitive electrical components downstream.
- Electrical Safety Compliance — Replacing a degraded or failed AC Reactor with a genuine OEM unit helps maintain the designed over-current and surge protection behavior of the GLW-180H electrical system.
An AC Reactor is an inductive coil wired into the power circuit of a welder to regulate current flow and suppress electrical noise and voltage spikes. By adding impedance to the circuit, it smooths the output waveform, which directly affects arc stability and the quality of the weld. When an AC Reactor degrades or fails, operators may notice erratic arc behavior, inconsistent output, or damage to other electrical components caused by uncontrolled current surges.
