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.
