Cause:
This is not a fault. It is a normal welding-mode display record and can be ignored.
Troubleshooting:
When the welding mode is changed to simulated welding, an information entry with ID 5020 can be seen on the log screen.
Solution:
Ignore directly.
Case sharing:
Each time the welding mode is switched to simulated welding, the log screen adds an information entry with ID 5020 to inform the user of the current welding mode.
