Fastener diameter capacity extending from M8 to M24
Full support for standard drawn arc and SRM processes
Heavy three-phase 400 V power stage for continuous work
High-capacity diode bridges, inductors & terminal lugs

Precision Welding Guns PH-3N SRM Series

Soyer PH-3N SRM welding guns feature an integrated magnetic coil that generates a radial magnetic field around the arc column. The precision stud lift mechanism eliminates spatter and ensures complete root penetration for studs up to M12 without requiring disposable ceramic ferrules.

Integrated electromagnetic coil for SRM magnetic focus
Fastens M3 through M12 studs on structural steel grades
Micrometer lift adjustment with dynamic dampening
Interchangeable chucks, support legs & harness cables

Compact Contact Stud Welding Guns PS-1K Series

Handheld welding guns Soyer PS-1K and PS-9 deliver capacitor discharge stud fastening up to M8 with positioning accuracy of 0.1 mm. Low tool weight of 2.3 kg and an ergonomic grip enable operators to install threaded studs inside congested cabinets and restricted industrial enclosures.

Fastener positioning accuracy rated within 0.1 mm
Welding range M3 to M8 with lengths from 6 to 35 mm
Lightweight impact-resistant polymer body weighing 2.3 kg
Precision guide bushings, pressure springs & chucks

CNC Stud Welding Machining Centres KTS Series

Automated coordinate tables Soyer KTS series deliver high-throughput stud fastening on large panels and switchgear sheets. Gantry mechanics with closed-loop servomotors maintain positioning accuracy of 0.15 mm and repeatability of 0.05 mm at travel velocities up to 500 mm/s.

Clamping surfaces from 800x1020 mm up to 2250x4200 mm
Linear positioning axis travel speeds up to 500 mm/s
Closed-loop ball screws providing 0.05 mm repeatability
Axis servomotors, linear rail carriages & air clamps

Selecting SOYER Stud Welding Technology: Capacitor Discharge versus SRM Arc

SOYER equipment offers two primary fastening methods depending on sheet thickness and required fastener diameter. For thin sheet metals from 0.5 mm (electronic enclosures, control cabinets), capacitor discharge units BMS-9 and BMS-9V with PS-1K hand tools provide ultra-fast weld cycles.

Rapid capacitive energy release prevents burn-through and protects the reverse sheet finish from heat markings.

For heavy structural steel fabrications thicker than 2 mm with fastener sizes up to M16 or M24, inverter systems BMK-16i and BMH-30i deploy patented SRM technology.

A radially symmetrical magnetic field rotates the arc column without disposable ceramic ferrules, producing metallurgical joints stronger than the fastener base material.

High-Throughput Fastening Automation with KTS Series CNC Coordinate Tables

In high-volume manufacturing of elevator panels, architectural cladding, and industrial switchgear, automated coordinate tables Soyer KTS series optimize production throughput.

Machining centres KTS-1050, KTS-1550, and KTS-2600 integrate closed-loop servomotors providing positioning accuracy of 0.15 mm and repeatability of 0.05 mm at travel velocities up to 500 mm/s.

The multi-axis gantries accommodate up to four independent welding heads paired with automated UVR bowl feeders, enabling simultaneous installation of diverse stud thread dimensions within a single continuous clamping setup.
