1.Temperature controls utilize core technology, adopting microprocessor-PID programming for high-speed 100ms real-time tracking of soldering iron tip temperatures, with real-time calibration! Outlet temperatures are extremely stable.

2.The heating element employs an imported high-power heating element for fast temperature compensation, particularly suitable for desoldering crude terminals, large joints, and difficult to reach spots, not to mention general solder joint desoldering.

3.An anti-static design effectively prevents damage to delicate components;

4.Automatic fault detection and alarm functions;

5.Employs new solid-mold manufacturing processes, withstanding voltage and drop damage; employs a blue ferroalloy soldering iron base for durability.

6.YH soldering iron handle wire employs a high-temperature silicone wire (undamaged when 300o soldering tip contacts silicone wire for 30 seconds);

YIHUA939BD+ have above all function,also additional below function:

a)Sleep Function: The soldering iron automatically detects when it is unattended and not in use, pauses for a set duration prior to sleep mode, and automatically cools to 200 ℃. It will then enter sleep mode to prevent soldering iron oxidation and effectively extend soldering iron head service life while retaining energy savings and environmental protection. The sleep time ranges from: 0~99 minutes, in 1 minute intervals. Users can set the time according to personal usage patterns. If the sleep function is not necessary for the soldering iron, the sleep time should be set to 0.

b)Auto-OFF Function: Once the soldering iron enters sleep mode, the program will start to keep track of time. If the soldering iron has not been activated before the set off time, it will automatically shut off to safe energy and protect the environment. The auto-off time ranges from: 0~99 minutes, in 1 minute intervals.

c)Celsius/Fahrenheit Display Temperature Function: To satisfy market demand in different regions, the Company has designed a temperature display mode.
