DIY High Voltage Arc Igniter Module – PCB Kit DC 3V–5V

Build your own high-voltage arc generator with this compact DIY electronics kit. Powered by a DC 3V–5V input (ideal with a 3.7V 18650 lithium battery), this pulse arc igniter module produces a striking purple high-temperature arc up to 8mm in length — perfect for hobbyists, electronics enthusiasts, and makers who love hands-on soldering projects.

Please Note: This kit is shipped as bulk components that require soldering and assembly. Suitable for users with basic electronics and soldering skills. Handle with care — high-voltage output is produced during operation.

Key Features

Assembly Notes

Identify and separate the three wire types included in the kit. Apply a thin coat of solder (tin) to each wire end.
Use a small screwdriver to coil any excess wire neatly — the thicker wire goes on the right side of the board.
Bend the tips of the two translucent output wires to approximately 5mm apart (arc electrode spacing).
Connect your DC 3–5V power supply, power on, and observe the arc!

⚠️ Safety Guidelines

Do not operate the module continuously for more than 1 minute at a time — allow adequate time for heat dissipation between uses.
Keep away from flammable materials during testing. Never touch the output terminals while powered on.
This kit is intended for educational and hobbyist use by adults with electronics experience. Keep out of reach of children.

Frequently Asked Questions

Q: What power source is recommended for this DIY arc igniter kit?

A: A 3.7V 18650 lithium battery is the recommended power source. The module accepts a DC 3V–5V input and draws approximately 5A of current (15W or more), so a capable lithium battery ensures stable arc performance at 5–8mm distance.

Q: Do I need soldering skills to assemble this kit?

A: Yes. This kit is shipped as unassembled bulk components that require soldering. You will need to tin the wire ends, wind the coils, and adjust the arc electrode spacing. Basic soldering experience and appropriate tools (soldering iron, solder, screwdriver) are required before assembly.

Q: How long can I run the module continuously?

A: It is recommended to limit each powered session to no more than 1 minute at a time. Allow the module to cool down between uses to prevent overheating. The resin-encapsulated transformer is designed for reliable long-term use when operated within these guidelines.

Q: What is the output arc voltage and frequency of this module?

A: The module outputs a pulse voltage of 0.5kV to 0.8kV at a working frequency of 20kHz–25kHz, producing a purple high-temperature arc spanning 5–8mm between the electrode tips.
