Features: Adopting automatic PID controlled technology for accurate temperature and stable performance. The heating part has long lifespan. Lead-free welding and soldering, quickly heating up to 450°C within 1 minute, saving up to 70% electricity. The handle is lightweight and non-slip, with long wire for flexible operation and longtime use without fatigue. The product can be used continuously for 24 hours. Copper base structure allows high heat transfer efficiency; the electroplating is dense and corrosion resistant; pre-tinned solder tip can be more effective to uniform solder, and effectively prevent oxidation. This 50W portable soldering station is suitable for mobile phone repair, electronic equipment maintenance, PCB/ circuit board maintenance and so on. Note: Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
