This is a Yihua 939D+ Iv Temperature Adjustable Soldering Station.

939D+ Iv has a great new feature that will keep it in the ranks of one of the best soldering iron stations. The model 939D+ Iv is digitally controlled by a Dual Core Microcomputer Processor which helps give much more stability, durability, and reliability to this unit. This unit now also features Magic Temperature Compensation technology which is the result of incorporating PID(Proportional, Integral, Derivative) Technology into our product. This allows for quick temperature correction ( in milliseconds ) to maintain tip temperature stability on any IC board you are working on. (Magic Temperature Technology sometimes known as Programmable Control Technology is one of the most sophisticated types of heat control systems in the world today. ) This model also has 3 Preset Memory Functions that can be used in soldering iron stations. You can also program the soldering iron to go into a Sleep Mode after your desired minutes of non-use (0 99 minutes), which is very convenient and energy save.

Features:

1. Rapid heating from room temperatures of 30 up to 300
2. The stations performance, precision and stability satisfy the work standards of professional hand soldering, micro- soldering, mobile phone repair, laptop repair, circuit board repair, test lab usage, educational usage and other fields of application.
3. Rotatable display screen. It is convenient to adjust the display screen position via slight press
4. Equipped with a ground wire to remove static electricity
5. X2 type solder holder include a cleaning kit (rosin + brass wool ball), a cleaning sponge, a residue tray with protective edge, a solder spool holder, a row of tip storage slots in a single holder package. It can store, clean, and protect soldering iron.
