Lead-free Soldering Station Intelligent Soldering Station LCD Thermostat Electric Soldering Station Iron Anti-static Adjustable Thermostat YIHUA 939D+ 

   1.Temperature controls utilize core technology, adopting Samsung 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); 

  7. Sleep function ,Auto-OFF Function , Celsius / Celsius/Fahrenheit Display Temperature 

  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 ºC. 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 safeenergy and protect the environment. The auto-off time ranges 

   from: 0~99 minutes, in 1minute intervals.  

  c)Celsius/Fahrenheit Display Temperature Function: To satisfy market demand in different  

  regions, the Company has designed a temperature display mode.  

  8.Three-section storage function: the temperature of each storage section can be preset  

  based on customer needs and the appropriate preset value of CH1/CH2/CH3 can be 

 selected rapidly depending on the soldering environment, making soldering convenient!  

  9.The soldering iron has an iron tip cleaner and internal rosin. The rosin aids in the 

 soldering of circuit boards by removing oxide films on the iron tip, reproduces oxidation, 

 reduces iron tip surface tension, and rapidly removes oxides. 

  10.The 939D+ enclosure is developed exclusively by our company. We have strengthened  

  the enclosure with improved resistance to impact and pressure, enabling more the security  

  of the product during transport.
