A professional quality, self-igniting soldering iron, hot knife, flameless heat tool and torch kit

Compared to other soldering irons on the market, the Master Ultratorch® UT-100Si-TC is a superior heat tool that allows you to quickly and efficiently heat, ignite, solder, desolder, terminate specialty connectors, and do so much more. This professional-grade soldering iron features best-in-class, oxygen-free, and copper-based Ultratip® soldering tips with thick iron and chrome plating to ensure extra-long life and higher thermal connectivity than its competition. Each Master Ultratorch® UT-100Si-TC comes with three soldering tips and a variety of accessories, all packed in a rugged plastic carrying case for your convenience that contains additional slots for storage of optional tips and Ultratane® butane. With a full tank, you can enjoy variable temperature control up to 1,202° F for up to two hours.

When operated as a heat tool, the heated gas flows directly from the end of the heat tip and can be used to heat, dry, or shrink as necessary. Best of all, you can adjust the tip temperature by simply adjusting the gas control lever. When operated as a soldering iron, heat conducts at the tip and applies solder when the tip is touched to the work surface. The multi-function Master Ultratorch® UT-100Si-TC also comes with a one-year warranty in the event of a defect in materials or workmanship, so we can replace any part that shows evidence of a defect without charge.
