280787 - Miller Ignition Coil for Kohler CH440 Engine

Reliable Ignition for Your Miller Equipment

The Miller 280787 Ignition Module is a critical replacement component designed specifically for Miller engine-driven welders powered by the Kohler CH440 engine. In the world of industrial welding, equipment downtime translates directly to lost revenue. When your engine-driven welder refuses to start due to a lack of spark, the ignition module is often the culprit. This genuine Miller part (OEM) ensures that your machine is restored to its factory specifications, providing the reliable ignition timing and strong spark required for the Kohler Command Pro series engines to run smoothly.

Ignition modules, often referred to as ignition coils or magnetos in small engines, are subjected to intense heat and vibration within the engine compartment. Over time, the internal windings or the solid-state electronics can degrade, leading to weak spark, intermittent misfires, or a complete failure to start. The Miller 280787 is engineered to withstand the harsh environments typical of job sites, featuring durable potting that seals the internal components against moisture, dust, and vibration. This ensures a long service life and reduces the frequency of maintenance intervals.

Installing genuine Miller replacement parts is essential for maintaining the warranty and performance of your equipment. While aftermarket options may exist, they often lack the precise timing advance curves required by the Kohler CH440 engine. An incorrect ignition curve can lead to hard starting, reduced power output, and even engine overheating. By choosing the Miller 280787, you are guaranteeing that the ignition timing is perfectly synchronized with the engine's rotation, allowing your welder to deliver the consistent arc stability and auxiliary power you depend on.

This module comes ready to install, typically including the high-tension lead and spark plug boot. Whether you are a fleet manager maintaining a lineup of rental welders or an owner-operator relying on a single machine, keeping your engine's ignition system in top condition is paramount. Trust in the quality and fitment of the Miller 280787 to keep your Kohler-powered equipment running efficiently.
