Fusion ring 8497310
Instruction sheet
06/06 SF
1 Fusion ring
2 Shaft
3 Wooden handle
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 application 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 conjunction 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.
