I finally checked a review:
"Some of the advertising shows people touching the tip immediately after a soldering operation. In reality it does cool quickly, but not exactly instantly. If you've had the iron hot for a couple of minutes while soldering wires or trying to desolder a medium or large sized component, don't touch the tip immediately. It will still be very hot depending on how long you've been powering the unit. Power and heat are power and heat even though the tip does cool incredibly fast compared to traditional soldering guns or irons."
