15.4 Error code descriptions
Error
code
Description
1 Program memory error (EPROM)
The program memory is damaged.
This fault does not disable any functions.
Action: Restart the machine. If the error persists, call a service engineer.
2 Microprocessor RAM error
The microprocessor cannot write/read to the internal memory.
This fault does not disable any functions.
Action: Restart the machine. If the error persists, call a service engineer.
3 External RAM error
The microprocessor cannot write/read to the external memory.
This fault does not disable any functions.
Action: Restart the machine. If the error persists, call a service engineer.
4 5 V power supply low
The power supply voltage is too low.
The current welding process is stopped and cannot be restarted.
Action: T urn off the mains power supply to reset the system. If the error persists, call a
service engineer.
5 Intermediate DC voltage outside limits
The voltage is too low or too high. Too high a voltage can be due to severe transients on
the mains power supply or to a weak power supply (high inductance in the mains or a
phase lost).
The power source stops and cannot be restarted.
Action: Turn off the mains power supply to reset the system. If the error persists, call a
service engineer.
6 High temperature
The thermal overload cutout has been triggered.
The current welding process is stopped, and cannot be restarted until the cutout has reset.
Action: Check that the cooling air inlets or outlets are not blocked or clogged with dirt.
Check the duty cycle being used, to make sure that the equipment is not being overloaded.
7 High primary current
The power source is drawing too much voltage from the DC that is supplying it.
The power source stops and cannot be restarted.
Action: Turn off the mains power supply to reset the system. If the error persists, call a
service engineer.
8 Low battery voltage +3V, (controller)
Battery voltage too low . If the battery is not replaced, all data stored will be lost.
This fault does not disable any functions.
Action: Call a service engineer to replace the battery.
8 +15VC power supply, (Mig 4500i)
The supply voltage is too high or too low.
Action: Call a service engineer.
8 +15V power supply, (Mig 4000i/Mig 5000i)
The supply voltage is too high or too low.
Action: Call a service engineer.
8 +15V power supply, (wire feeder)
The supply voltage on the PCB is too high or too low .
Action: Call a service engineer.
