OVERVIEW

Genuine Miller Replacement Part for Precision Welding

The Miller 260507 Actuator Push Button Assembly is a critical replacement component designed to maintain the operational integrity of your Miller MIG welding guns. Specifically engineered for the MDX Series, this actuator assembly serves as the mechanical interface for the trigger switch, ensuring that every press results in reliable arc initiation. In industrial environments where equipment downtime translates directly to lost productivity, using genuine OEM parts like the 260507 is essential for guaranteeing fitment and performance.

Constructed from high-durability materials, this push button assembly is built to withstand the rigorous conditions of a welding shop, including exposure to heat, spatter, and mechanical wear. Over time, the moving parts within a MIG gun handle can degrade or become obstructed by debris. Replacing the actuator assembly is often the solution to resolving issues with intermittent firing or 'sticky' triggers that do not return promptly. By choosing the authentic Miller 260507, you ensure that the replacement part matches the exact tolerances of the original handle design, preventing internal misalignment that could damage the microswitch or the gun handle itself.

Maintenance personnel and shop managers rely on Miller Electric's consistent quality control. This assembly comes as a complete unit ready for installation, minimizing the time required for repair. Whether you are refurbishing a fleet of MDX-100 or MDX-250 guns or performing a quick field repair, this component provides the assurance of factory-spec performance. It is an indispensable item for any MRO inventory supporting Miller welding equipment.

FAQ

The Miller 260507 is the Actuator Push Button Assembly used to replace the trigger button mechanism in specific Miller MIG guns, primarily the MDX series.

Typically, this part number refers to the mechanical actuator (the plastic button assembly) that presses the switch. The electrical microswitch is often a separate component inside the handle.

Yes, this is a genuine Miller Electric OEM replacement part.

If your MIG gun trigger feels loose, sticks, is physically cracked, or does not spring back after being pressed, the actuator assembly likely needs replacement.

No, it is designed for specific models, notably the MDX series (like the MDX-100 and MDX-250). Check your gun's manual or parts breakdown to confirm compatibility.

Installation is generally simple and involves opening the MIG gun handle case (usually held together by screws), removing the old actuator, and seating the new one in place.
