109436 - Miller 109436 Gas Solenoid Valve 115V

Reliable Gas Control with the Miller 109436 Solenoid

The Miller 109436 Solenoid Valve is a critical component for maintaining the integrity of your welding operations. Designed specifically for Miller Electric welding power sources, this 115V AC gas valve acts as the gatekeeper for your shielding gas. When you pull the trigger on your MIG gun or activate the foot pedal on your TIG setup, this solenoid opens instantly to allow gas flow, protecting the molten weld pool from atmospheric contamination. Conversely, it shuts off tightly when the arc is extinguished, preventing costly gas wastage.

Genuine OEM Quality

When repairing industrial equipment, using Genuine Miller OEM parts is essential for longevity and performance. The 109436 valve is manufactured to Miller's exact specifications, ensuring it fits perfectly into the mounting brackets and connects seamlessly with the existing wiring harness of compatible machines. Unlike generic aftermarket valves that may have different coil resistance or flow characteristics, this OEM part guarantees that your machine operates exactly as the engineers intended.

Technical Specifications & Compatibility

This unit is a 2-way valve featuring 1/4-18 NPT female ports, making it compatible with standard plumbing fittings found inside many Miller chassis. It operates on 115 Volts AC, which is a common control voltage for many industrial Millermatic and Syncrowave power sources. It is commonly found in legacy machines such as the Millermatic 200, 250, and various S-Series wire feeders. Replacing a faulty solenoid is often the solution to issues such as porosity in welds (valve not opening) or hissing sounds from the machine when idle (valve stuck open).

Installation and Maintenance

Replacing the gas solenoid is a straightforward maintenance task that can significantly extend the life of your welder. Over time, contaminants in the gas lines or general wear and tear can cause the internal plunger to stick or the seal to degrade. Installing a fresh 109436 valve restores crisp on/off action. Ensure power is disconnected before servicing any internal components. This valve is designed for durability, but like all electromechanical parts, it may eventually require replacement after years of heavy service.
