290660 - Miller Rear Panel Assembly for Multimatic 255

Genuine Miller Replacement Rear Panel

The Miller 290660 Panel Assembly is a genuine OEM replacement part designed specifically for the rear section of the Miller Multimatic 255 welding machine (Service Stock Number 907813). When a welding machine's outer casing is damaged due to impact, drops, or heavy shop use, it compromises the protection of the sensitive internal electronics and the efficiency of the cooling system. This direct-replacement panel restores your machine to its factory condition, ensuring that your investment remains safe and operational.

Constructed to the exact specifications of the original manufacturing process, this rear panel features all necessary cutouts for input power cables, gas shielding hoses, and cooling fan exhaust. Because it is an authentic Miller part, you can trust that the screw holes and mounting tabs will align perfectly with the machine's chassis, making installation straightforward for maintenance personnel. Keeping your welder's enclosure intact is critical for safety, preventing accidental contact with internal high-voltage components and shielding the interior from excessive shop dust and metal filings.

This assembly is sold individually and is intended for the Multimatic 255 platform. Please verify your machine's serial number or stock number (907813) to ensure compatibility before ordering. Whether you are refurbishing an older unit or repairing accidental damage, the Miller 290660 ensures your welder looks and functions as intended.
