How to fix it – “Please check the pressure of the protective gas!”

“Please check the pressure of the protective gas! After confirming, click ‘OK’ to cancel the alarm.”
This issue is common and can usually be solved within one minute by adjusting the system settings.
This is not a hardware fault, but simply a parameter mismatch between working modes.
