YIHUA-939D+/937BD+/939BD+ Constant Temperature Soldering Station

1. YIHUA-937BD+/939BD+ constant temperature soldering station makes full use of SAMSUNG SCM. The PID procedure helps realizing the real-time tracking, correction of soldering iron temperature. And the PID temperature correction cycle is 100ms.
2. With amazing temperature compensation speed, it comes with stable temperature with minimum temperature error. Therefore, this soldering station adapts to all sorts of hostile environment.
3. Equipped with the high-power Hakko heater, it is suitable for all the desoldering applications, especially those large, complicated solder joints. This anti-static soldering station will cause no damage to the delicate components.
4. The product is manufactured with new solid mold. In this regard, it withstands pressure and has impact resistance. It is more durable and pretty with the blue ferroalloy holder.

In addition to the design of energy saving and environmental protection, YIHUA-939BD+ constant temperature soldering station is added with the follower functions.

1. Sleep Function
The soldering iron of YIHUA-939BD+ constant temperature soldering station automatically detects its own working status. When not in use, it will be in a quiescent state. When arriving to the set sleep time, the iron will be lowered to 200 ° C in temperature, so as to enter into the sleep state.

This function can avoid the oxidation of iron head, thereby prolonging the iron tip service life. Also, it is beneficial for energy conservation and environmental protection. The sleep time range is from 0 to 99 minutes. You can set the sleep time according to the use conditions. If you do not need the sleep function, you can set the sleep time to zero.

2. Automatic Shutdown Function
After the soldering iron enter into the sleep state, the program starts timing. If the soldering iron is still in the sleep state within the set shutdown time, the equipment will be automatic power off, thus to save energy. The automatic shutdown time range is from 0 to 99 minutes.

3. Celsius / Fahrenheit Temperature Display Function
This temperature display mode is designed to meet the requirements of different regions.

939D+ has all above features of 939BD+, in addition below 2 functions:
1. Three storage sections: CH1/CH2/CH3, each storage segment can store all the features of the current machine (eg: temperature, all function values on display can be stored), you can quickly switch between each storage segment.
2. -50 °C to +50 °C temperature compensation function.
