The compact stud welding unit LBH 710 is designed for drawn arc and short cycle stud welding. It convinces through easy operation and high welding quality. The robust construction ensures high reliability and high power-on time. All functions are indicated by clearly arranged LED. The welding time is continuously adjustable by the rotary knob on the front. The LBH 710 can optionally be equipped with a shielding gas module for welding with shielding gas for weld pool backing and with an automatic module to control the automatic stud feeder VBZ and an automatic welding gun.
