Overview
A butane fuel cell feeds a small burner that heats a soldering tip, blows hot air or runs as a pinpoint torch in this Bernzomatic tool. You adjust the flame for each job and lock it on for continuous use.
Three tools in one cordless body suit electrical repair, jewelry and heat shrink away from outlets. Child-resistant ignition adds safety. Fuel and run time details are missing.
Who it's for
Field repairs, crafts and heat shrinking on the go suit the portable design. Heavy electronics work is better on a corded station.
Pros and cons
- Three functions in one tool
- Cordless and portable
- Flame lock for steady use
- Butane not included
- Run time not listed
Performance notes
Heat output depends on flame setting and gas flow, so small tips heat fast while larger joints need more time. The hot air nozzle shrinks tubing without direct flame. Refilling is needed as fuel runs down.
