DC 3V–5V High Voltage Arc Igniter DIY Module – PCB Kit
DC 3V–5V High Voltage Arc Igniter DIY Module – PCB Kit
The DC 3V–5V High Voltage Arc Igniter Module is a compact, resin-encapsulated PCB kit designed for electronics enthusiasts, hobbyists, and DIY circuit builders. Powered by a standard DC 3–5V input (ideally a 3.7V 18650 lithium battery), this pulse arc generator produces a vivid purple high-temperature arc capable of instantly igniting paper, tinder, or thin materials — perfect for science experiments, prototyping, and learning about high-voltage circuits.
⚠️ Important Notice: This product is intended for experienced electronics hobbyists who are comfortable working with circuits and soldering. The kit ships as bulk components that require soldering and assembly. The seller guarantees components are in good condition at the time of shipment but cannot guarantee results post-assembly. Please read all instructions carefully before purchasing.

Assembly Tips
- Identify the three wire types from the transformer and tin the wire ends with solder.
- Wind any excess wire into a spring-like coil using a screwdriver. The thick wire goes on the right side.
- Bend the tips of the two translucent output wires to approximately 5mm apart.
- Connect a 3.7V 18650 lithium battery to the input terminals.
- Power on and observe the high-voltage arc between the wire tips.
⚠️ Safety Notice: Do not run the module continuously for more than 1 minute at a time. Ensure adequate heat dissipation during operation. Handle all high-voltage components with appropriate care.

Frequently Asked Questions
Q: What power source is recommended for the DC 3V–5V arc igniter module?
A: The manufacturer recommends using a 3.7V 18650 lithium battery as the power source. This provides a stable DC input within the 3–5V operating range and delivers enough current (approximately 3–5A) to generate a consistent 5–8mm arc at the output terminals.
Q: Does this arc igniter module come pre-assembled or do I need to solder it myself?
A: This kit ships in bulk (unassembled) and requires soldering by the buyer. It is designed for electronics enthusiasts with circuit assembly experience. The transformer is pre-encapsulated in resin, but the PCB components need to be soldered and wired according to the included instructions.
Q: How long can the arc igniter module run continuously?
A: It is recommended to limit each continuous operation session to no more than 1 minute to prevent overheating. Always ensure proper heat dissipation around the module during use. The resin-sealed transformer is built for reliable long-term use when operated within these guidelines.
Q: What is the output voltage and arc distance of this high voltage igniter module?
A: The module outputs a pulse voltage of 0.5kV to 0.8kV at a working frequency of 20kHz–25kHz, producing an arc distance of 5–8mm between the output wire tips. When the secondary output is not connected to a rectifier diode and capacitor, it generates a purple high-temperature arc of up to 0.8cm in length.
