Specifications: 1: The 80W soldering iron adopts internal heated ceramic technology, heats up quickly and has high temperature stability. 2: The soldering iron with high-resolution LCD screen allows you to see the temperature more clearly. 3: There is a power switch and an independent temperature adjustment button on the soldering iron, so you can easily and freely turn it on/off or adjust the desired temperature. 4:Unique non-slip soft rubber handle for safe soldering and maximum comfort Scope of delivery: Soldering iron x 1 Assorted soldering iron tips x 5 Solder wire x 1 Y soldering iron stand x 1 Sponge x 1 Soldering steps: 1: Depending on the materials you are joining and the type of solder you are using, set your soldering iron to the correct temperature 2: Once your iron is heated to the correct temperature, grasp the iron by the handle in one hand and hold a piece of solder in the other hand. Hold the hot iron where the two metal pieces meet for about a second to heat them. You want to heat the metal parts, not the solder itself. 3: Touch the heated components with the solder. As the solder melts, it flows into the gaps it needs to fill. Continue to introduce solder until a sufficient amount has melted. While you need enough solder to make a solid connection, you also don't want to have too much solder. 4: Allow the solder to cool down on its own without any action. 5: Check the quality of the solder joint. A good bond appears smooth, even and shiny. Make sure there are no problematic gaps between components or excess solder. Tips: 1. Please be careful when using the tools and better store them in a place where children cannot reach. 2. Please switch to 392 model when not using the iron. And please do not let the soldering iron work at high temperatures. 3. Do not apply too much pressure when welding. As long as the iron tip completely touches the solder joint, heat can be transferred. 4. To avoid oxidation, please clean the soldering iron tip and tin all surfaces of the tip with a layer of solder after use. If there are black oxides on the iron tip, please clean it with a WET sponge first.
