Feature: 1. Various styles of packages to choose from 2. Temperature visualization 3. ABS anti-skid design 4. Smart thermostat chip 5. Safe and fast heat conduction 6. The internal heating type is smaller in size and faster in heat conduction. Equipped with an intelligent constant temperature chip, the efficiency is higher 7. The external heat type has a simple structure, slow heat conduction and instability, no intelligent constant temperature chip, and a shorter service life 8. The ceramic heating iron core is energy-saving and stable, and conducts heat from the inside to the outside. 9. Intelligent constant temperature control, stop heating after the electric iron reaches the specified temperature. If the temperature of the electric soldering iron drops, the chip will be thermostated to the specified temperature again after induction. 10. Digital display screen HD LCD backlight screen, equipped with blue backlight data clear and easy to read temperature Specifications: Item model number: SL103 Material: PVC+Silicone+Stainless Steel Power: 60W Product line length: 1.37 meters Product function: multi-function button to adjust temperature Heating core: ceramic internal heating Adjustable temperature: 180-500& 8451; Specifications: EU Plug and US Plug (optional) Package Included: US Plug : US SL103 24-piece set of electric soldering iron*1+silicon protective cover for soldering iron tip*1+anti-static tweezers*1+digital multimeter*1+soldering iron bracket*1+solder absorber*1+thermocouple*1+electricity test pen *1+Tin wire*1+Soldering iron tip*5+Soldering tool*6+Cut pliers*1+Rosin*1+Maintenance copper wire*1+Multimeter test lead wire*1+Zipper storage bag*1 EU Plug :  EU SL103 24-piece set of electric soldering iron*1+silicon protective cover for soldering iron tip*1+anti-static tweezers*1+digital multimeter*1+soldering iron bracket*1+solder absorber*1+thermocouple*1+electricity measuring pen *1+Tin wire*1+Soldering iron tip*5+Soldering tool*6+Cut pliers*1+Rosin*1+Maintenance copper wire*1+Multimeter test lead wire*1+Zipper storage bag*1
