Fault symbols
CMI 161 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 error
The indicator flashes, when the power source is
overheated.
Leave the machine on until the built-in fan has
cooled it down.
Selected error codes
Current measurement error
The current sensor may be defective
and need replacing, or the plug is unconnected.
Temperature error

Allow the machine to cool and check that cooling
profiles are clean. Check that the fan is functional.
