Functions
- Logicfunctions of the welding process
- generating and monitoring supply voltages
- driving powerup-relais
- driving power unit/units
- monitoring control and operating elements (DS20BF, remote control, torch buttons)
- driving fans
- driving coolingpump
- monitoring flowmeter
- monitoring mains- and output voltage
- generating signal „welding current on“
- managing communications between PC and machine
- managing and storage of all welding parameters
- CAN-bus
LED displays :
If the LEDs are indicating a malfunction which can not be relieved by switching the machine off and on again,
it is recommended that the pc-board DP-MAPRO is exchanged.
