12.4.2 Library Mode
In the library mode, you can call up and modify charging voltages, depending on
stud diameter (UD/pins).
Simultaneously press both arrow keys of welding time ( ) next to the welding time
display ( ) for about one second.
The display welding time shows 0 - 06 (06 means the set welding current and wel-
ding time for stud diameter of 6 mm).
You can pre-select the stud diameter (6 mm to 22 mm) with both arrow keys
( longer – shorter).
After about 3 seconds the display ( ) jumps onto the preselected welding time and
the display (
) onto the pre-selected welding current.
In addition, you can modify the welding time and welding current individually by
pressing the arrow keys (as described above).
If you are working with shielding gas, different welding parameters
for stud diameters (from 6 mm to 12 mm) are available in library
mode.
12.4.3 Conversion Current Curve
It is possible to adjust the current curve for a special welding method. There is a dif-
ference between drawn-arc stud welding with ceramic ferrule or with shielding gas.
Drawn-arc stud welding with ceramic ferrule
Simultaneously press both arrow keys (welding current lower – higher) ffor
about one second. The display welding current shows the current scale with dots.
1.9.4.0.
Drawn-arc stud welding with shielding gas
Simultaneously press both arrow keys (welding current lower – higher)for
about one second. The display welding current shows the current scale without dots:
