The BMS-4 Akkumat SOYER stud welder runs according to the principle of capacitor discharge with
tip ignition as defined in DVS Leaflet 0903 (DVS = German Welding Society).
This system uses the sudden discharge of a capacitor battery to generate arc energy.
Stud tip touches workpiece
Ignited arc generates a fusion
zone on stud and workpiece
Stud is plunged into the
welding pool. Material solidifies
and stud is welded
