Fault symbols

Temperature fault
The indicator is switched on, when the power source is
overheated. Leave the machine on until the built-in fan has
cooled it down.
Current fault
The indicator flashes when start current or welding current
is higher than permitted by the welding machine's efficiency. Make
sure that wire speed/current and voltage are set correctly.
Fault symbols
The indicator flashes when other types of errors occur. At the
same time an error code is shown in the display.
Selected error codes
Mains supply fault
The indicator is displayed, when the mains
voltage is too high.
Connect the welding machine to 400V AC, +/-15% 50-60Hz.
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
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
Wire feed fault
or
The indicator is displayed, if the wire feed motor is overloaded.
The wire feed motor or magnet valve may be defective.
Other types of faults
If other fault symbols are shown in the display, the machine shall
be switched off and then on to dispose of the symbol. If the fault
symbol is shown repeatedly, repair of the power source is required.
Contact your distributor with information of the fault.
When separate units are connected, the following error codes can be
