Error handling
SIGMA Select 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 in case of insufficiant circulation of the cooling liquid due to faulty connection, defective parts 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 (IGC)
Gas fault exists due to a to low or high 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.
