Fault symbols
SIGMA has a sophisticated built-in self-protection system.
2
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 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.
