Protecting welding parameters from unauthorised access
NOTE
The machine code is set to the factory setting of 000 after each reset (see chapter
"Resetting welding parameters to the factory setting".
See chapter "Changing the three-digit machine code" for information on how to change
this code).
To protect against unauthorised or unintentional changes to the welding parameters, you can lock the
machine controls with a software key (3-digit machine code).
If the access lock is active, only the following parameters can be changed:
• Welding current (within a previously defined range).
• Switch
display.
• Switch welding parameters (JOBs)
