The desoldering gun is controlled automatically by the micro-processor. The digital control electronics, high-quality sensor and heat exchange system guarantees precise temperature control of the soldering tip. The highest degree of temperature precision and optimal dynamic thermal behavior under load conditions is obtained by the quick and accurate recording of the measured values in a closed control circuit, and this design is especially for the lead-free production technics. Desoldering gun with a power of 90W (heat up rating 200W) and a wide spectrum of soldering tips（N5 series) can be used anywhere in the electronics field. The high power and gun type design makes this desoldering gun suitable for fine desoldering work. The heating elements are made of PTC and the sensor on the desoldering tip can control the desoldering temperature quickly and accurately.
