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.\u003c\/p\u003e\n\u003ch4\u003eQ: Do I need soldering skills to assemble this kit?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003ch4\u003eQ: How long can I run the module continuously?\u003c\/h4\u003e\n\u003cp\u003eA: 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.
