Access control
To protect against unauthorised or unintentional adjustment of the welding parameters on the machine,
the control input can be locked with the aid of a key switch.
In key switch position 1 all functions and parameters can be set without restriction.
In key switch position 0 the following functions and parameters cannot be changed:
• No adjustment of the operating point (welding performance) in programs 1–15.
• No change of welding or operating mode in programs 1–15.
• The welding parameters can be displayed but not changed in the control's function sequence.
• No welding task switching (JOB block operation P16 possible).
• No change of special parameters (except P10). Restart required.
5.10 Special parameters (advanced settings)
Special parameters (P1 to Pn) are applied for customer-specific configuration of machine functions. This
allows the user maximum flexibility in optimising their requirements.
These settings are not configured directly on the machine control since a regular setting of the
parameters is generally not required. The number of selectable special parameters can deviate between
the machine controls used in the welding system (also see the relevant standard operating instructions).
If required, the special parameters can be reset to the factory settings
