Features: 1. The machine installation is simple and not easy to make mistakes. 2. Volume after installation: length 24cmX width 12cmX height 41cm; 3. Packing size: 35cmX23cmX19cm; 4. Input voltage AC 90V~230V; 5. The arc length is within the range of 15 cm, and the power is adjustable within the range of 5W~30W. Tesla Coil Features: 1. To simulate lightning, you can use tape to stick a metal wire on the ball to discharge or connect another ground wire to start the arc, which will be more effective. 2. The gas lamp can be lit from a distance of about 30 cm, and the effect is good at night or in a dark place. 3. The power is adjustable in the range of 5~30 watts, the current is a few milliamps, and the feeling of touching the arc with your hand is similar to that of touching the static electricity. Gradually approaching the metal ball from far to near, it just started to feel numb. If you see the arc too close, you will feel some pain. The arc pulse can be adjusted very slowly so that most people can accept it. It should be noted that the principle of Tesla coil and paradigm generator is different. Tesla coil belongs to AC output and cannot produce hair erection effect. Precautions: 1. Can not be used to light the light-emitting diode (LED), the light-emitting diode will be damaged by electricity. 2. When the power is on, only the discharge ball can be touched, and other circuit parts cannot be touched. The machine requires good grounding. If there is abnormal ignition, please adjust the gap of the lighter. The gap of the lighter is generally within 2mm. 3. Tesla coils have strong electromagnetic interference, and heart patients should stay away from those equipped with pacemakers. Keep away from precision instruments (at least 1 meter above), including switching power supplies, stepper motors, PLCs, mobile phones, and network communication equipment. Unlike the upper divider, the fingerprint lock cannot be opened. Regarding security issues: 1. There is a feeling of being electrocuted. If you want to know if you can accept this feeling, you can use the electric ignition device of a lighter to feel it. The feeling is similar. I personally think that the feeling of the machine is weaker than that of the lighter. 2. We do not advocate touching the arc, which is a voluntary experience. 3. It is a difficult problem to make people feel the charm of the arc and to be safe. But after all, this is a high-voltage electricity. Although there is a high-frequency skin effect in theory, there are many problems to be considered in practice. Even if the current flowing on the surface of the conductor is too high, it will burn the skin, so the current should be within the acceptable range of the human body, and the power should not be too high. In this way, the power can be adjusted within 30 watts and the power can be adjusted, and the arc pulse can be adjusted very slowly. In this way, most people can accept it. In fact, this is a high-frequency pulse of 30 watts, which is the average power of the machine. The instantaneous power is still very high. Of course, I would like to thank the first person who dared to try to touch the arc. It feels like static electricity.
