Operating instructions Soyer Bolzenschweißtechnik
Possible cause
• Stud inserted too deep in the stud chuck
• Mechanical problems with the gap welding gun
• External voltage of other stud welding devices
• Error in the device (thyristor short circuit)
• Welding capacitors faulty (leakage current)
• Charging current source faulty
• Defective quick-discharging resistor
• Safety relay is clamping or sticking
• Switching times of the safety relay too long
The mains voltage must be between 90...130 V or
180...275 V at 50...60 Hz. The device automatically
recognises both ranges.
During high welding sequences, the device may
be exposed to an increased ambient temperature
(>45°C) or direct sunlight.
