Miller XMT 350 MPA Front Display Board Assembly 242725

Restore Control to Your XMT 350 MPA

Is the display on your Miller XMT 350 MPA flickering, blank, or unresponsive? The Miller 242725 Circuit Card Assembly is the direct OEM replacement you need to get your machine back in the fight. The front panel display is the brain of your user interface—without it, you can't access the advanced pulsed MIG menus, adjust your voltage accurately, or monitor your amperage output. This kit comes as a complete assembly, including the circuit board and the front cover, making it ready to drop into your existing machine chassis.

Important Fitment Warning: Welding machines often have internal revisions that change which parts they use. Before you order this board, you must verify that it fits your specific unit. We strongly recommend calling Miller Technical Support at (800) 558-3517 with your serial number in hand to confirm that part number 242725 is the correct board for your serial range. Electronic repair parts like this are non-returnable once shipped. If you install it in the wrong machine or if the underlying issue is actually a main power board failure, you cannot return this part. Measure twice, cut once.

This board is designed for the "MPA" version of the XMT 350, which features more complex controls than the standard VS or CC/CV models. It handles the synergic lines and pulse parameters that make the MPA special. If you are not a certified repair technician, be extremely careful during installation. Static electricity can fry a new board instantly. If you are unsure about the diagnosis, take your machine to a local service center. Don't let a bad display stop your production—replace it with the genuine Miller 242725 and get back to welding.
