How to solder:
1.Prepare solder and soldering iron; Specially, it's necessary to keep the tip clean, which should be coated with solder.
2. Please wet the sponge before using.
3. Use the soldering iron to heat the weldment, such as PCB leads and pads, and keep the weldment heated evenly.
4. When the temperature is high enough, put the solder wire close to the joint, the solder will melt and flow freely.
5. Please remove the solder wire when the tin is enough.
6. Take away the soldering iron in a direction approximately 45°and power off.
7. Don't pull the soldering iron tip outward and use it in that way, which will shorten the heating element life.

ATTENTION:
1. PLEASE keep it away from children. Do NOT allow to be used it as a toy.
2. PLEASE use it in a well ventilated space.
3. When installing or replacing the soldering iron parts, it must be done after disconnecting the power supply. It must be installed or replaced after the soldering iron is cooled.
4. The metal tips will become crisp and easy to break in the high temperature, PLEASE waiting the temperature drop down then change.
5.Under any circumstances, Do NOT touch the metal part of the soldering iron to guard against burns
