DIODE CONTROL RECTIFIER AND POWER BOARD The Power Board receives approximately 40 VDC from the Diode Control Rectifier . In turn, the Power Board supplies a variety of regulated DC voltages to the Weld Control Board, which it uses to power its many circuits and communication functions.
WELD CONTROL BOARD The Weld Control Board performs the primary interfac- ing functions to establish and maintain output control of the Power MIG 300 machine. The function generator and weld files reside within the Weld Control Board hardware and software.
E-7 E-7 POWER MIG 300 Return to Section TOC Return to Section TOC Return to Section TOC Return to Section TOC Return to Master TOC Return to Master TOC Return to Master TOC Return to Master TOC WIRE DRIVE MOT OR AND FEED- BACK The Wire Drive Motor is controlled by the Feeder Board and the Weld Control Board.
THERMAL PROTECTION T wo normally closed (NC) thermostats protect the machine from excessive operating temperatures. These thermostats are wired in series and are con- nected to the Weld Control board. One of the ther- mostats is located on the Chopper Assembly board, and one is on the secondary of the Main T ransformer .
