    • The color of the Touch-Safe Indicator LED provides information about the status of the soldering iron tip. Note: the soldering iron grip is always safe to touch.

    • The LED only functions when the soldering iron is connected to a power source—so use caution when handling an unplugged iron if you don't know how hot it is.

    • Blue LED: The iron has cooled below 40 °C (100 °F), and the tip is safe to touch.

    • Purple LED: When pulsing, the iron is actively heating up or cooling down. When static, the iron is in Idle Mode. The iron tip is not safe to touch.

    • Orange LED: The iron has reached the set temperature and is ready to solder. The iron tip is not safe to touch.
