Canceling password protection
7.2.2 Activating the control panel lock
The control panel lock function prevents the welding parameters from being changed by mistake.
The control panel lock only permits wire feed and retraction movements, gas tests, and parameter saving.
Switching off the device does not cancel the control panel lock. Resetting the welding parameters and the
internal functions deactivates the control panel lock.
The parameter protection function can be used to give only a selected group of persons permission to
change parameters. The parameter protection function can only be canceled by entering a password.
