SL402 Electric Soldering Irons 220V Welding Repair Mica Heating Core 40W Temperature Adjustable Solder Tip Tools

Electric soldering iron is a commonly used tool in electronic and electrical maintenance and production, used for soldering electronic components, circuit boards, etc, This product is made of high-quality materials and has the characteristics of efficient heating, adjustable temperature, safety and reliability.Specifications:Temperature range:60W power 440C~450C/40W power 380C~400C/30W power 320C~330CHeating core:Mica heating core. Operating:1.Power preheatingHold the electric soldering iron in your hand and keep the soldering iron head perpendicular or slightly tilted to the ground for easy operation.2.Tin SolderingBring the soldering iron head close to the solder joint and gently heat the solder joint and the surrounding metal parts to enable the solder wire to melt smoothly.3.Supplement SolderAdd an appropriate amount of solder wire to the solder joint to fully melt and wrap the solder joint.4.Solder Joint CoolingWhen the solder is completely melted and wraps the solder joint, quicky remove the soldering iron tip and let the solder joint cool naturally.
