Locking the control system – CODE (MC 3)
Optimally configure the control system for the welding task. The control system can then be locked to prevent
third parties from changing the settings. To do this, press the Fx button until CODE appears on the display,
then use the left-hand knob to select any number between 0000 and 9999. Once the number has been set,
the control system is locked by tapping the wire feed button. The only functions that can now be used are
'gas test', 'wire feed' and 'wire speed correction'. All other functions are locked. To unlock the control
system, tap the Fx button again until CODE appears on the display. Now use the knob to select the same
number as before and press the 'wire feed' button. The control system returns to normal mode.
Fx options (MC 3)
This function can be used to change the lower-level basic settings. Press and hold the Fx operating button
(for more than 1 second) to access the options. The following options can be changed:
EC 1/2: not used for this machine type
Hold: the setting for the display hold time in seconds (0 = infinite to 25 s)
Reset the control system/memory locations (see next point)
Set the torch type and length: tap until 'tch' appears on the left-hand display. The following 3-digit number
appears in the middle display:
Use the knob to set the connected torch type.
Example: 204 = water-cooled torch with a length of 4 m
Enter the residual cable length (ground cable and any intermediate cable assembly): tap until 'cbl' appears
on the left-hand display then set the total length of all cables (excluding the torch length!) in the right-hand
display (the cable cross-section used as a basis appears in the middle display, e.g. 35 mm²).
Example: 12 = total cable length of 12 m (maximum 40 m possible)
NOTICE
• The torch type and cable length must be precisely set in order for the control system to work optimally.
To save the new settings, exit options menu by tapping the wire feed button.
