This butane-powered tool functions as a flameless heat tool, soldering iron, and torch. When used as a soldering iron, the UT-50 can be used for both boat design and repair as well as jewelry making, sculpting, soldering thermoplastics, and so much more. When used as a butane torch, the UT-50 is a valuable choice for home improvement projects and plumbing applications. When used as a flameless heat tool, the Ultratorch® UT-50 soldering iron is perfect for embossing powders and special inks as well as softening adhesives, removing surface mount components, and spot drying.

With a full tank of Ultratane® butane, you can operate this pen-sized torch for up to 20 minutes of continuous use. This high-quality heat tool uses a patented gas catalyst reaction system that produces 20 to 60 watts of power equivalent to an electric iron.
