A 8 Watt Soldering Iron is a hand tool used in soldering. It supplies heat to melt the solder so that it can flow into the joint between two work pieces. A soldering iron is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Its fast heating, high quality mica heating unit provides thermal stability for long life. Anti-roll handle is heat- and inpact - resistant, with ribbed design for fingertip control.
