Miller 233146 Power Interconnect Board for XMT 350

Genuine Miller 233146 Power Interconnect PC Board

The Miller 233146 Circuit Card Assembly is the designated Power Interconnect board for select Miller inverter welding power sources, most notably the XMT 350 series (including VS, CC/CV, and MPa models). In modern inverter architecture, the power interconnect board serves as the critical bridge between the high-power switching modules and the logic control board. A failure in this component can result in loss of output, inability to strike an arc, or specific error codes related to power bus communication.

This replacement PC board is a direct-fit OEM component. It features the precise connectors, trace layouts, and componentry required to handle the signaling within the XMT 350's chassis. Technicians prefer genuine Miller parts because they eliminate the guesswork associated with generic repairs. The board is pre-populated and tested to meet Miller's rigorous quality assurance standards, ensuring that once installed, your machine returns to its factory-rated duty cycle and arc characteristics.

Installation Note: Installation of this component involves working inside the welder chassis where high voltages may be present. It is highly recommended that this part be installed by a certified welding equipment repair technician. Always disconnect power and discharge capacitors before servicing internal components.
