The Schöler & Bolte DUOFIX is a battery-powered stud welding unit with double welding gun for simultaneous welding of two studs. The battery operation enables mobile use without electrical power supply. With DUOFIX two studs M3 for the mounting of heat cost allocators are simultaneously welded. Stud spacing can be adjusted variably. A separate ground connection is not necessary. 
With a weight of just 4,6 kg (unit incl. gun) DUOFIX is especially light. The unit is integrated into a robust carrying case, which offers much space for additional tools, welding studs and accessories.
DUOFIX is very easy and comfortable to use. The integrated battery offers a capacity of 700 double welds. With a life period of approx. 1000 charging cycles it is extremely long-lasting. The newly developed double welding gun offers a range of innovative functions, which significantly facilitate daily work.
Alternatively (e.g. when the battery is empty), DUOFIX can be operated at every power socket. Optionally, a cable for charging directly at the 12V on-board socket of a motor vehicle is available.
