The Multiquip 1971885003 DC Reactor GLW-180H is a genuine OEM component designed for GAW180HE, GAW180HEA, and GAW180HE1 series gasoline arc welders. Sourced directly through Multiquip's authorized parts program, this reactor meets the exact electrical specifications required for stable welding output on these machines. If you're experiencing erratic arc behavior or irregular current delivery, replacing the DC reactor with the correct OEM part restores proper welder function. DHS Equipment stocks Multiquip 1971885003 to get your GAW180H-series welder back to full operation.
Key Features
- Matched Electrical Specification — Built to the exact inductance and current rating of the original GLW-180H reactor, ensuring stable DC output under welding load.
- Direct OEM Replacement — Connects to the existing wiring harness and mounting points on GAW180HE-series welders with no adaptation needed.
- Confirmed Fitment — Verified for use on GAW180HE, GAW180HEA, and GAW180HE1 Multiquip gasoline arc welders.
- Arc Stability Restored — A functioning DC reactor smooths current flow to the electrode, producing a consistent arc. A failed reactor causes fluctuating output and poor weld quality.
- Electrical Safety Compliance — Using the correct OEM reactor maintains the designed current-limiting and surge-protection behavior of the welder's electrical circuit, protecting both the operator and internal components.
The DC reactor is an inductive electrical component in the welder's output circuit that smooths and regulates the direct current delivered to the welding electrode. By limiting rapid fluctuations in current, it stabilizes the arc and produces cleaner, more consistent welds. When the reactor degrades or fails, the welding arc becomes unstable and inconsistent, and the welder's internal electrical components may be exposed to damaging current spikes.
