  • DC power supply
  • Induction Coil
  • 2 Banana plugs

Setup Procedure:

  1. Connect the induction coil to the power supply.
  2. Set the air gap to about an inch and turn on the power supply. Set it to 8VDC.
  3. Make sure the rotary switch on the induction coil is locked in the on position.
  4. Adjust the small air gap at the bottom by turning the knob.
  5. It should get to a point where you can just tap the bottom air gap to get it started and it will keep going.

  2. Tap the bottom air gap to get it to start.
  3. When finished, turn off the power supply.

High Intensity Ultraviolet Light
Do not stare at the spark gap. Dangerous amounts of UV radiation may be emitted.

High Voltage / High Frequency
Due to the high frequency high voltage, keep away from sensitive electronics.
Avoid long contact, as electrical burns may occur.

Note: Not very effective and hard to use. The table top tesla coil is recommended.
This unit is slightly more powerful than the table top tesla coil and portable tesla coil.
