The ITW/Miller 238907 is a solid-state control circuit card assembly designed as the logic engine for Millermatic 140 and 180 Auto-Set welding power sources. It manages wire feed speed, power delivery, and automatic parametric matching for MIG (GMAW) and Flux-Cored (FCAW) operations. The board is constructed on FR-4 substrate and features a conformal coating for environmental protection.
Features
Auto-Set Logic: Automatically sets welding parameters based on wire diameter and material thickness inputs.
Tip Saver Short-Circuit Protection: Shuts down output when the contact tip shorts to the work piece to protect internal components and extend tip life.
Smooth-Start Technology: Manages initial arc parameters to provide spatter-free starts.
Thermal Overload Protection: Monitors duty cycle and airflow to shut down the unit and activate over-temperature indicators during faults.
Self-Resetting Motor Protection: Integrated circuit eliminates the need for external fuses for the wire drive motor.
Solid-State Contactor Control: Keeps welding wire electrically cold until the torch trigger is pulled.
Manual Mode Support: Allows for manual setting of voltage and wire feed speed outside of Auto-Set profiles.
Trigger Reset: Permits resetting the unit at the torch rather than the power source after a short-circuit fault.
