Wechart: 630531309
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 500 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.
