Product image.
A butane soldering iron is the cordless tool for soldering away from an outlet, out in the field or on the car, and the good ones heat fast and hold a usable tip temperature. For electronics you want fine tips and adjustable heat, not a crude flame torch. Look for adjustable temperature, fine tips, and easy ignition.
Top picks at a glance

The same Weller butane iron without the full tip kit, cheaper if you already have tips or want just the iron.

View on Amazon →What should you look for in butane soldering iron for electronics?
A few things separate a good butane soldering iron for electronics from a frustrating one: adjustable temperature, fine tips, fast ignition and refill, and stand and cap. Weigh these before you buy.
- Adjustable temperature: fine electronics work needs controllable heat, not one hot flame.
- Fine tips: small conical or chisel tips for through-hole and small joints.
- Fast ignition and refill: piezo ignition and easy butane refill keep it practical.
- Stand and cap: a cap-stand and safety cover matter for a hot cordless tool.
