280555 - Miller 280555 Auxiliary Power PC Board with Program

Miller 280555 Auxiliary Power Control Board

Maintain the reliability of your welding fleet with the Miller 280555 Circuit Card Assembly. This component is the designated replacement for the auxiliary power control module in select Miller power sources. The auxiliary power circuit is essential for running job site tools, lights, and grinders directly from your engine drive or inverter welder. When this board fails, you lose the versatility that makes your Miller machine a standalone workstation.

This is a programmed assembly, meaning it arrives with the specific software logic required to manage the auxiliary output parameters. Using genuine Miller parts is the only way to guarantee that the replacement board communicates correctly with the main control board and the power generator assembly. The 280555 is built to withstand the vibration, thermal cycling, and electrical noise typical of industrial welding environments, ensuring a long service life after repair.
