The compact LBS 130 Inverter type CD Stud welding unit is designed for capacitor discharge stud welding. It convinces through easy operation and high welding quality. Through the electronically clocked inverter charging board extremely short charging times and thus quick welding sequences are accomplished. The robust construction ensures high reliability and high power-on time. All functions are indicated by clearly arranged LED.
The charging voltage is continuously adjustable by the rotary knob on the front. Optionally, the LBS 130 can be equipped with an automatic module to control the automatic stud feeder VBZ and an automatic welding gun.
