The coil with 6-turn winding acts as a high current coil for needle-point melting experiments.
•Do not allow the equipment to come into contact with liquids.
1.Safety instructions
•The safety of operators and of the high-voltage coil itself can only be guaranteed when it is used according to the instructions.
•Carry out the experiment on a heat-resistant surface. The melted part of the pin naturally falls downwards due to gravity.
•Only use needles with heads that fit into the screw terminals.
•After the experiment allow the remains of the pins to cool down for at least 5 minutes.
•Do not cover air vents.
•Any modifications to the transformer set-up must be made with the primary voltage switched off.
•Do not open the coil case.
