Error handling
SIGMA Galaxy has a sophisticated built-in self-protection system. The
machine automatically stops the gas supply, interrupts the welding
current and stops the wire feeding in case of an error.
Selected errors:
Torch cooling fault
Cooling fault is indicated on machines
equipped with water flow kit in case of
no circulation of the cooling liquid due
to faulty connection or choking
Check that the cooling hoses are
correctly connected, top up the water
tank and check welding hose and
branches. The cooling fault is cancelled
by pressing shortly on the
P
–key pad.
Gas control fault
Gas fault exists due to a to low or high pressure on the gas flow.
Make sure that the pressure on the gas flow is higher than 2 bar and
less than 6 bar, corresponding to 5 l/min and 27 l/min.
The fault is disconnected by adjusting the manual gas flow to 27 l/min.
The gas fault is reset by a short pressure on the
P
–key pad.
Error log
All errors are saved in the machine error
log in the menu Service. The error log
can be distributed, when inserting a

pad:
The error log is now saved at the SD-
