are relative programs whose welding current settings are a percentage based on the
general welding current setting.
5.6 Access control
The key switch is only available for machines which are fitted with the "OW KL XX5" option ex
works.
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.
