Spanhitari f. bolta og annað

principle of operation:

• there is an alternating magnetic field, the metallic object (e.g.
  nut), in the induction coil, acts on the induced eddy currents as an
  electrical resistance and thus heats up (max. 900°C)
• allows heating of screws/nuts without heating surrounding components
  too much or even destroying them, as it is often the case when heated
  with a torch
• within the shortest possible time, e.g. rusty nuts are heated and can be loosened
• using on e. g. ball joint pinch bolts and other items on axle and engine
• a formless coil (length: 800 mm) allows using the device also for
  heating of components (bearings, etc.) e.g. bearings in which the
  heating facilitates disassembly or assembly
• includes the following induction coils
  • induction coil: 19 mm, length: 220 mm (for Ø 10-16 mm)
  • induction coil: 27 mm, length: 220 mm (for Ø 17-24 mm)
  • induction coil: 50 mm, length: 235 mm (for heating small surfaces)
  • formless coil, 780 mm, for heating of components
• max. power: 1.5 kW
• max. current: 7.5 A
