2620094 - Miller MDX EZ-Select Circuit Board Assembly with Cover

Restore Control with the Miller MDX EZ-Select PCBA

If you run a Miller MDX MIG gun with the EZ-Select feature, you know exactly how much time it saves. Being able to toggle between weld programs or adjust settings right from the handle—without walking back to the power source—is a game-changer for productivity, especially when working on large weldments or in tight spaces. However, if that functionality stops working due to a damaged board or worn-out contacts, your high-tech gun becomes just a standard torch. The Miller 2620094 PCBA W/Cvr is the exact replacement part you need to get that convenience back.

This kit comes with the Printed Circuit Board Assembly (PCBA) and the protective cover that fits seamlessly into your MDX gun handle. It is designed to replace the internal electronics that manage the EZ-Select system. Over time, the electronics inside a MIG gun handle can be subjected to drops, impacts, and the constant heat of welding, which may lead to failure. Symptoms of a bad board often include unresponsive buttons or intermittent signal loss to the welder. Swapping out the old board for this genuine Miller replacement restores the crisp, reliable response you expect from your equipment.

Installation is straightforward for those familiar with MIG gun maintenance. The unit is designed to fit perfectly into the MDX handle architecture, ensuring that the buttons align correctly and the cover seals out dust and spatter. Because it is a genuine Miller part, you don't have to worry about compatibility issues or "hacking" the wiring to make it work. It plugs in and performs just like the original.

Don't let a small electronic failure slow down your fabrication process. The EZ-Select feature is there to keep you under the hood and welding, not walking back and forth to the machine. By repairing your gun with the Miller 2620094, you extend the life of your MDX gun and maintain the efficiency that justifies the investment in premium welding gear.
