The ColdHeat Soldering Pen is the most popular cordless soldering tool in North America and the only product that uses Cool Touch technology to safely and effectively tackle all types of light duty electronic, home, and craft projects. It features an advanced ceramic tip that has been designed to improve durability and is 15 times stronger than its predecessors. The ceramic tip will heat up in less than a second to 700°F but will also safely cool down in seconds, for most applications. It has a built-in project light and an automatic shut-off. It is completely cordless, so it can go anywhere you go, because it uses 4 AA batteries (not included). The package includes a ceramic tip and bit of solder and it comes in a durable hard-sided storage case.
