Overview
A cordless, self-igniting butane soldering iron and torch kit with 7 interchangeable tips, an adjustable flame, and a metal refillable tank rated for up to 75 minutes of run time per fill.
Butane is not included, and the description points out the tank is metal rather than the plastic common on cheaper kits.
- Flame adjusts from 1/2 to 2 1/2 inches, up to 2400 F
- Soldering tip mode runs up to 1100 F
- Metal tank refills in about 10 seconds, up to 75 minute runtime
- 13-piece kit with self-igniting trigger and carrying case
Who it's for
Suits mobile technicians, hobbyists and anyone doing soldering or heat work away from an outlet, from electronics repair to heat-shrink and small welding tasks. Less suited to precision electronics work that needs a fixed, low temperature, since this runs hot and is flame based.
Pros and cons
- Butane not included
- A few buyers needed a warranty replacement before it worked reliably
- One reviewer found performance depends on using purified butane
Performance notes
The flame adjusts from about 1/2 inch to 2 1/2 inches and runs up to 2400 F on its own, or up to 1100 F when fitted with a soldering tip, self-igniting off a trigger with a lock button so it can run hands-free. A full metal tank is rated for up to 75 minutes and refills in about 10 seconds.
