Fault symbols
RALLY MIG 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.
Troubleshooting and solution

Current measurement error
The current sensor may be defective and need
