Input Voltage: AC 90-125V AC180-240V, 50/60Hz Input Power: 105-110W max Temperature: 250°C- 450°C(482°F-842°F) Dimension: 160(L)*110(W)*130(H) Weight: 1.1KG Main Features 1. System utilizes switching power supply to achieve an efficiency rate of near 85% and above; it is set with power factor compensation circuit, Q≥0.85. 2. It is designed with dynamic power, which allows an output of 110W maximum power, when soldering under low and high temperature. 3. It utilizes low-temperature soldering ability, efficient, quality solder joints can be achieved at 320°C, which effectively extends tip?s life. 4. It automatically analyzes the soldering period and returns to stand by status under low temperature to avoid tip oxidation under high temperature 5. It intelligently identifies big and small soldering points and provides different temperature compensations 6. The temperature recovers rapidly and the maximum temperature decline is not more than 30°C 7. It is with reliable power supply system and strong anti-jamming. The products all adopt heating elements and tips with long life, and excellent quality. Special design makes that tip replacement cost is a fraction other brands.
