Cold Heat Solder Iron for electronics, think twice

Cold Heat Soldering Iron — better than a traditional iron?

The Coldheat iron requires an non-conventional soldering technique. It is best used for occasional simple DIY electrical or mechanical work, such as soldering a thin wire onto a small bulb, soldering two passive components together or fixing a small broken wire; occasional spot-repairs in difficult places, where you were unable (or couldn’t be bothered) to plug in an ordinary iron and wait for it to heat up; quick, spot-joint repairs where you might want the iron to be cold enough to put away quickly afterwards; isolated electronic repairs where you were satisfied that no surrounding components would be damaged by the voltage present across the tip.
