features of quick heat and constant temperature precisely. It could be supplied by variable frequency power with low voltage 22V. There is 60W power to increase heat. Also, the anti-static constant soldering could be used widely in the world. Features: We could know the temperature of electric soldering iron well through the LED digital screen. The heat of electric soldering iron speed up rapidly, the temperature reach to 350℃ (662℉) only around 6-8 seconds, and it is in constant temperature. There is a p-rotection of overheat for safety operation, and it also extends the using lifespan. It is used T12 series heating core and temperature s-ensor for controlling temperature quick and steady. Light and easy to operate, the working efficiency get improved. There is a setting temperature system which is controlled actual temperature of soldering tip. The soft rubber handle brings more comfortable and safety control during your work time. Stable soldering iron stand, you can wet the sponge and place the soldering iron safely and have a rest. Wide applications, it is suitable for electric maintenance, DIY joints on appliance, circuit board, model making and etc..
