FAULT CODES
Code Description
12 Communication error (warning)
The load on the system CAN bus is temporarily too high.
Action: Check the equipment to ensure that only one wire feed unit and/or remote
control unit is connected, also see Section "13AP1:7 The CAN bus", page 16.
15 Lost messages
The bus CAN circuit indicates that a message has been lost. No functions are
disabled by this fault.
Action: Check that all units are correctly connected to the CAN bus, also see
Section "13AP1:7 The CAN bus", page 16.
22 Transmitter buffer overflow
The control board is unable to transmit information to the other units at a sufficiently
high speed.
Action: A break in the bus line can cause this fault. Check the CAN cabling. Turn off
the mains power supply to reset the unit.
23 Receiver buffer overflow
The control board is unable to process information from the other units at a
sufficiently high speed. This fault is caused by abnormal loading of the
microprocessor.
Action: Turn off the mains power supply to reset the unit.
27 Out of wire
The wire feed unit is not feeding any wire. The current welding process will be
stopped, and cannot be restarted.
Action: Load new wire.
At present, wire monitoring is fitted only to special versions of wire feed units.
28 Stack overflow
The program execution does not work.
This fault should never occur in reality: the fault code is intended as an aid during
development work. Contact ESAB if the fault does occur.
32 No gas pressure
Gas pressure is too low.
Action: Check the gas valve, hoses and connectors.
Gas monitoring is fitted only to special versions of wire feed units.
