Cause:
The welding configuration file does not match the software.
Troubleshooting:
Check whether the welding configuration format under ftp://192.168.39.220/ConfigureFiles/ corresponds to the software version.
Solution:
Contact after-sales support, copy the ftp files from the controller, and send them to after-sales personnel.
Case sharing:
If the software version is SRS_ but the welding configuration file used in the controller's ftp is version V1.5.0, error 3804 will be reported at startup.
