The Solder Pro 100K is a completely portable multi-function heat tool that can be used as a soldering iron, heat gun, hot knife cutter and blow torch all in one! The soldering iron tip makes this unit comparable to a 100 watt electric soldering iron. The blow torch (use without any tip attachments for temperatures up to 2400°F) is perfect for heavy soldering. With the heat blower or deflector attachments, the unit is ideal for heat shrink tubing. Finally, the hot knife attachment makes this a great way to get a fray resistant braided sleeve.
