Parameters Input voltage AC 110~240V, 50~60Hz Rate power 40W (210 Handpiece) Handle 210 Temperature range 90~450 ? / 194~842 ? Main unit dimensions L147*W143*H106±5mm Ambient temperature 0~40 ? / 32~104 ? Display LCD Tip-To-Ground resistance < 2 Ohms QTY 16 PCS/CTN Inner box size 20.8*19.8*12.8 cm Master carton size 43*41*52.5 cm Unit weight 1.2 kg/PCS CTN weight 20 kg/CTN Features 1. In only 3 seconds, the soldering station can heat up to 380?. 2. Easy to disassemble and install heating element. 3. The soldering station features functions up to 5, one Hotkey to Operate. 4. Fahrenheit/Celsius can be easily switched to meet different market demands. 5. Four Programmable Presets Available You can preset temperature in each memory channel for different needs. When soldering, you can quickly select the suitable preset temperature settings in CH1/CH2/CH3/CH4 according to different soldering applications. 6. Digital Temperature Correction Function When temperature deviation happens because of environmental impact or replacing the spare parts such as heating element, soldering iron, you can use this function to correct. 7. Sleep Mode When the soldering iron is placed back into the holder, and if the set temperature higher than 200?/392?, the iron will enter sleep mode, and cool to 200?/392?. If the set temperature is below 200?/392?, it will remain unchanged. You can pick up the soldering iron to wake the station. This extends the lifespan of the heating element, conserves energy, and protects the environment. 8. Automatic Shut-Down When the soldering iron enters sleep mode and not be picked up within approximately 30minutes, the soldering station will automatically shut off, you can pick up the soldering iron to restart the soldering station. This prevents leaving the station ON unsupervised, or forgetting to turn OFF the station. 9. Buzzer Prompt The soldering iron has built-in buzzer to remind.
