Features: Lead-free tins wire will be achieved 8seconds melt of tins when STM32 soldering station is used at its power between 110-240V; Auto-sleep function: to set sleepng times,its setting range is 0-60 mins,default sleep setting times is 30 mins; Default sleeping times is 30 mins,it means soldering Station will go into stand still after 30 mins.and simultaneously,the soldering station will entry to Sleep state,temperature will drop to 150C.After press encoder,the soldering station will wakeand temperature wil be up to previouis temperature before sleeping; Description of display:After conflirming the installation of component is right.The newiron tip is inserted into the handleand the display screen will be fash or ERROR,it is normal.After heating 5-20minutes.it will retum to normal gradually.Temperature control range is 150-480.The common welding temperature is 300-380.So in order to protect the working life of the soldering iron tip,recommended that the temperature be not more than 380.
