YIHUA-939, YIHUA-939D Constant Temperature Digital Display Soldering Station

1. YIHUA-939D soldering station uses SAMSUNG SCM PID procedures to realize the real-time tracking and correction of soldering iron temperature.
2. It comes with fast temperature compensation speed, which ensures stable temperature with minimum temperature error.
3. This constant temperature digital soldering station suits to all kinds of environmental extremes. It can automatically detect the failures and has alarm function.
4. With the high-power imported heater, it is not only suitable for general small solder joints, but also applicable for desoldering large, complicated solder joints.
5. Our constant temperature digital display soldering station is designed to be anti-static, thus to avoid the damage to the delicate components.
6. Its handle line applies silicone wire of high temperature resistance and good flexibility. Even when exposed to the 300℃ soldering iron, the silicone wire has no damage within 30s.
