5.15 Protecting welding parameters from unauthorised access
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:
5.15.1 Welding data display
To the left and right of the LCD display on the control there are 2 “arrow keys” on each side for selecting
the welding parameter to be displayed. The
button is used to scroll through the parameters from the
bottom upwards and the
button is used to scroll downwards from the top.
As soon as changes have been made to the settings after welding (display on hold values) the display
switches back to the nominal values.
