Safety instructions
Caution: Build-up of high temperatures. Danger of
serious burns!
• Hold the apparatus only by the insulated handle.
• Set up the induction furnace on a heat-resistant
surface.
• Switch off the mains coil immediately after the
solder has melted.
2. Description
The fusion ring is used for demonstrating the applica-
tion of the Joule effect (induction melting).
The fusion ring consists of copper sheet which is
formed into a circular groove and attached to a
wooden handle. In the experiment, the fusion ring
acts as a secondary coil with a single winding in con-
junction with mains coil 8497420 and transformer
core with yoke 8497180 to form an induction furnace.
Ordinary tin-lead solder is well suited for use in the
experiment.
3. Technical data
Inner diameter: 57 mm
Length: 270 mm
Material: Copper
4. Operation
Additionally required:
1 Mains coil 8497420
1 Transformer core with yoke 8497180
Tin-lead solder
• Set up the experiment as shown in Fig. 1.
• Put the solder into the fusion ring.
• Switch on the mains coil.
• Switch off the mains coil immediately after the
solder has melted.
• Carefully remove the molten solder from the
fusion ring.
• Disposal of the solder must be in accordance with
local regulations.
