Soldering iron with ON/OFF switch: The soldering iron kit has an ON/OFF switch for easy operation. They can simply save energy and ensure safe welding. You should only turn it off if you don't want to use it. The adjustable temperature of 200~450C is specially designed for welding conditions at different temperatures. Rapid heating heat dissipation: The soldering iron uses ceramic induction technology, which can be quickly heated to the target temperature (adjustable temperature range 200~450C). Improved heat-resistant material and the four openings of the steel tube in the soldering iron design ensure rapid cooling. It accelerates heat dissipation and increases safety and heat resistance. Solder wire + desoldering pump: The soldering wire has a diameter of 0.8 mm and a weight of 50 g. It is harmless to the human body and can be used for various welding purposes and for a long time. The desoldering pump (sucker) is a high-pressure vacuum tube with an aluminum frame that allows easy one-handed operation. It has impact resistance, corrosion resistance and good heat dissipation. This tool set meets all your welding requirements. This sponge iron easily removes stains from the tip and extends its life. There is also a portable bag for easy storage of equipment and easy to carry. Application: Soldering iron sets are the best gift idea for home improvement, various applications electronics and circuit board repair, soldering, jewelry, guitar, watches, wiring, mobile devices, computer hardware, small jobs electronics, TV-capacitors or accessories etc!
