8 Components of the Stud Welding Unit
The stud welding unit is equipped with a library mode (3) . In the library mode, the
factory default setting of charging voltages, depending on stud diameter can be
called up and modified.
This library mode only applies tho the workpiece material mild steel (suitable for
welding) and the welding element material 4.8 (suitable for welding) and only when
using the welding guns C 08 and CA 08.
The following values are stored in the library mode:
Material
of welding elements
Diameter of welding elements
Charging
voltage
CDi 1502
in V
Welding rate
in studs/min

PT, UT IT
Material of workpiece: Mild steel (suitable for welding)
4.8 (suitable for welding)
M3, 3 mm -- 80 33
4.8 (suitable for welding) M4, 4 mm -- 100 30
4.8 (suitable for welding) M5, 5 mm 5 mm, M3 130 24
4.8 (suitable for welding) M6, 6 mm 6 mm, M4 170 14
4.8 (suitable for welding) M8, 7.1 mm 7.1 mm, M5 220 12
If both arrow keys ( ) are pressed simultaneously for approx. one se-
cond, 0. .3 appears in the display. (3 means the pre-set charging voltage for
stud diameter M3).
The bolt diameter can be pre-set with the two arrow keys ( increase -
decrease) (from M3 – M8). After approx. 5 seconds, the display changes to the
selected charging voltage. The capacitor battery is charged to this value.
The stud welding unit features an automatic mode (4) . In Automatic mode, you can
set the stud feeding time (blow time) for feeding the welding element from the feed
unit (VBZ) to the welding head or to the PAH-1 automatic welding gun.
If both arrow keys ( ) are pressed simultaneously twice in quick successi-
on, the blow time can be set.
The blow time can be pre-set with the two arrow keys ( increase -
decrease) (in quarter steps from 0 to 5 seconds). If "0" is set, the OFF display
appears (OFF means that the blow time (automatic mode) is switched off).
After approx. 5 seconds, the display changes to the charging voltage last set.
