6. Description of BMS-8N(V) stud welding devices
The main elements of the stud welding device and its features are described in
the following.
6.1 Type differentiation
The difference between the device types BMS-8N and BMS-8NV described in this
instruction lies in the different performances of the capacitor banks and therefore
in the welding performance.
6.2 Working method
With the SOYER® BMS-8N stud welding device, pins and threaded studs from
M3 to M8 (M10 with BMS-8NV and special gun) as well as many different weld
fasteners made of steel or stainless steel can be welded in accordance with
DIN EN ISO 13918 (capacitor discharge).
Welding of weld fasteners made of aluminium and brass is also possible.
6.2.1 Product features
• Patented “charging circuit” (Pat. No. 199 15 396.5) allowing highest welding
sequences during continuous application.
• High performance with a compact design and a small weight.
• Short charging cycles to increase productivity.
• Digital display of the charging voltage or the stud diameter.
6.2.2 Capacitor discharge stud welding
The SOYER® BMS-8N(V) stud welding device operates according to the
principle of capacitor discharge with tip ignition.
This system uses the sudden discharge of a capacitor bank to generate arc
energy.
