ATTEN AT989 constant temperature electric soldering iron soldering station knob temperature adjustment 65W with sleep

AT-989 ESD Safe Constant Temperature Controllable Soldering Station  MCU controlled temperature calibration with PID system equipped.  The heater using low voltage AC source to ensure the anti-static and no leakage, no interference.  Steady temperature setting with 200～480℃.  Legerity handle suitable for long time operation.  Unique temperature locks setting to avoid adjusting temperature. Features:   Easy Temperature Setting Set the desired temperature by knob control.   Unique temperature lock Using a hex wrench to tighten the hex nut on the underside of the knob mount.   ℃/℉ is available and exchangeable   Auto-standby function  After 10 minutes when not in use, it will auto-standby, heating element temperature will drop to 200℃. Picking up the soldering iron and it will back to normal working mode.   Auto sleep function In auto standby mode, the soldering station will auto sleep after 20 minutes, heater will drop to 100℃, pick up the soldering iron and back to normal working mode.    The LED indicator light display status when this device is power on. 1.The LED indicator light is steady on means this device is heating up 2.The LED indicator light is off means this device is not heating up (it may mean temperature overshoot, unsuccessfully connecting soldering iron handle or broken heating core). 3.Breathing state (The LED indicator light turn into lighter from dark then turn into darker, loop) means this device is under constant temperature. 4.The LED indicator light is flash means this device enter into sleep or standby status.
