2.1 Tip ignition technology
The SOYER stud welding systems run according to the principle of capacitor
discharge with tip ignition as defined in DVS Leaflet 0903 (German Welding
Society).
This system uses the abrupt discharge of a capacitor battery to generate
electric arc energy.
The electric arc is initiated via the calibrated and close fit ignition tip on the
welding studs and elements. The stud weld base and the opposite surface of
the workpiece are melted on. The stud is then automatically dipped in the thin
fusion zone or liquid weld pool. After the immediate solidification of the mate-
rial, an homogeneous high-strength joint is produced in an extremely short
welding time of only 1 - 3 milliseconds (0.001 - 0.003 sec.).
2.2 Stud welder set-up
The standard pistol to be connected to the stud welders BMS-10N and BMS-
10NV is the stud welding pistol PS-3 with control cable. The stud welders are
optionally equipped with an automatic module for the connection of the univer-
sal feeder UVR-250S and for fully automatic stud feed. It is necessary to use
the stud welding pistol PS-3A or the welding head SK-5A when welding with
automatic operation.
Optionally it is possible to connect the stud welding pistols PS-1, PS-1K, PS-
OK and PS-3 as well as the welding head SK-5A. These operating instructions
exclusively describe the stud welders BMS-10N and BMS-10NV.
For information regarding the stud welding pistols to be used as well as their
adjustment and the universal vibrator UVR-250S, please refer to the respective
operating instructions of the stud welding pistols or the universal vibrator UVR-
250S.
