Fault
code
Description
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.
26
Program operating fault
Something has prevented the processor from performing its normal program duties.
The program restarts automatically. The current welding process will be stopped.
This fault does not disable any functions. This fault should never occur.
Action: Contact ESAB if the fault does occur.
28
Stack overflow
The stack memory is full. This fault should never occur: the fault code is intended as
an aid during development work.
Action: Contact ESAB if the fault does occur.
29
No cooling liquid flow
The flow monitor switch has operated. The current welding process will be stopped,
and cannot be restarted.
Action: Check the cooling water circuit and pump. Water flow monitoring is an
option.
32
No gas flow
Gas flow is less than 6 l/min.
Action: Check the gas valve, hoses and connectors. Gas monitoring is fitted only to
special versions of the TIG and MIG machines.
