Fault Symbols - Migatronic SIGMA2 300 Compact Manuel D'instruction

2
SIGMA 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.
Errors are indicated by symbols and error codes.
Temperature fault:
The indicator flashes, when the power source is
overheated.
Leave the machine on until the built-in fans have
cooled it down.
Mixed transfer:
(only synergic welding programs)
The indicator is switched on and warns about the
setting area as it lies within mixed transfer with risk of
welding spatter.
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 a fault symbol is shown in the
display.
Selected error codes:
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.
Press the -key pad briefly to cancel the cooling
fault.
Mains supply fault:
The indicator is displayed,
when the mains voltage is too high.
Connect the welding machine to 400V AC, +/-15%
50-60Hz.

FAULT SYMBOLS
Wire feed fault:
The indicator is displayed, if the wire feed motor is
overloaded.
The wire feed motor or magnet valve may be
defective.
in case a gas control kit has been mounted. Gas fault
is 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. Gas fault is switched off pressing
down the
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 using the MultiFeeder or MWF 41
Slave, the following error codes are available
on the SIGMA
