The IEC Dissectible Transformer is the classic instrument for teaching the principles of the transformer.
The large iron core has a section of 35x35mm and the 'I' is clamped to the 'U' to close the magnetic circuit. Various special coils are available but the standard set contains a mains operated primary with on/off switch and a removable mains cable together with a low voltage, heavy current tapped secondary coil.
A plastic foot protects the work bench. The kit contains also a rugged 'spot welder' and a heavy copper ring that heats to melt wax or melt solder through induction.
The coil formers are made from heat resistant glass filled nylon and are unbreakable. A 'Thompson's ring' is included.
