Welding steps:

1. Weld the ship type switch first:

2. Loose parts with PCB board are easy to manufacture. Pay attention to the thickness of the transformer line, and other components can be welded according to the symbols and parameters printed on the board.

3. Three pads are made on the transformer board, and the pad hole in the middle is relatively large. This hole is welded with a thick enameled wire and a thin enameled wire at the same time. The thick enameled wire and the thin enameled wire should not be welded on the same side, such as the thick wire on the left and the thin wire on the right, or the thin wire on the left and the thick wire on the right, In short, do not use thick and thin lines on the same side.

Transformer structure:

The transformer has two primary windings, one group of thick copper wire is the main winding and one group of thin copper wire is the feedback winding. The secondary output is high voltage. The two copper wires, one thick and one thin, wound together in the transformer are positive poles, which are respectively connected to the tail of the main winding and the head of the feedback winding, and connected to the positive pole of the power supply.

Matters needing attention:

1. The transformer is designed with a maximum output of 15kV, and the maximum limit output shall not exceed 15kV, that is, 0.5-1cm arc. Higher output voltage is likely to damage the transformer. For long-term continuous operation, it is recommended to completely seal the transformer with insulating wax or epoxy resin after successful manufacture. No load is prohibited when it is not sealed! No load operation in the air will cause coil breakdown and damage due to insufficient air insulation strength!

2. After the kit is successfully manufactured, the applicable input voltage is 3.7V, that is, one 18650 rechargeable battery. If the input voltage needs to be increased, the resistance value needs to be increased (the default resistance of the kit is 120 Ω), otherwise the triode is easy to burn out. (maximum boost 6V)

According to the circuit diagram, the output of the coil is high-frequency and high-temperature electricity. When it breaks down in the air, it is a light purple arc without crackling, but the temperature is very high. It can easily ignite paper, plastic and even very thin iron wire (for example, in the chemical test in Junior middle school, the thin iron wire burns in oxygen, but it is not as violent as in oxygen.)

The key to the device is the stepup transformer with the secondary coil made of very thin wires providing the high voltage output thru red and blue insulated wires. In addition to the primary coil , there is a third winding of very thin magnet wire thatis the feedback winding that serves as input to the transistor (Q1) oscillator, connecting thru resistor, R1, and diode, D1, to the base of the transistor. Magnet wire is insulated thruout, and before assembly and soldering, clear off the insulation at the ends of the primary and feedback windings well wind sandpaper or steel wool so that solder can stick and a good connection will be made. Another critical step is polarity of the feedback signal from the feedback coil (coil with thinest wires for connection), To work at all , you need positive feedback so the transistor will oscillate and generate an AC input into the primary turn of transformer so it can be stepped up to high voltage. So if it doesnt work you may have to reverse/interchange your connections to the feedback coil.
