5.13.3 Protecting welding parameters from unauthorised access
The machine code is set to 000 ex works and after each reset- See 7.3 Resetting welding
parameters to the factory settings chapter.
The machine code can also be user-defined- See 5.13.3.1 Changing the three-digit machine code
chapter.
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)
