Miller 230V Gas Solenoid Valve for Millermatic 140/180 Series

Restore Your Millermatic with the Miller 216398 Gas Valve

Is your Millermatic welder failing to dispense shielding gas, or is gas leaking constantly even when the trigger isn't pulled? The issue is likely a faulty gas solenoid. The Miller 216398 230 VAC Valve is the direct replacement part you need to get your Millermatic 140 or 180 back in action. A functioning gas valve is critical for MIG welding; without it, your weld pool is exposed to oxygen and nitrogen, leading to weak, porous, and unsightly welds.

This 2-way custom port valve is built to Miller's exact specifications. It operates on a 230-volt circuit and features a 1/8-inch orifice that ensures the shielding gas flows smoothly and consistently to the nozzle. The installation process is designed to be maintenance-friendly, utilizing 1/4-inch friction terminals that slide onto your machine's existing wiring harness. This means you can often complete the repair right in your shop with minimal downtime.

Designed for durability, this valve handles the on/off cycling inherent in tack welding and long bead runs alike. It is compatible with several popular models, including the Millermatic 140 and 180 series (both standard and Auto-Set versions) and systems using the M-10 gun. Don't let a small part stop your big projects.

Installation Tip: Always disconnect power to your welder before opening the case to replace internal components. Verify that your machine's control circuit utilizes 230V for the gas solenoid, as indicated by this part number, to ensure proper operation and safety.
