Note: This little kit comes unsoldered and parts will need to be soldered to the board.
It uses a 3-5V power source, like a lithium battery to produce a very hot arc between the two points. Enough heat to light a cigarette or to combust a flammable gas.
The input terminal of this product is connected to DC 3-5V power supply. The output two-stage line end can produce a purple high-temperature arc of ≤0.8 cm or so, without hum, but the temperature is very high. It is easy to light paper cigarettes in an instant, and even a very thin wire is burnt in sparks (such as the scene where fine iron wire burns in oxygen during junior high school chemical tests, but not as severe as in oxygen)
The transformer has been packaged with resin, which has high safety and can work reliably for a long time. However, it is recommended that the unit is energized for less than 1 minute each time, pay attention to heat dissipation.
Voltage and current power: DC 3-5V, current 5A, 15W or more. A 3.7V 18650 lithium battery is recommended.
Output pulse voltage: 0.5kv-0.8kv
Working frequency 20khz-25khz
Arc distance: 5-8 mm
I have assembled the circuit but can't test it because I don't have 3amps at 5 volts available.
Really skinny wire to the right hole. Doubled up one in the middle and the one on the left to the left hole from the transformer. Clean them of the epoxy or burn it off when soldering it.
Mine had no instructions supplied with it. Took a few minutes to work out.
