• Prepare solder and soldering iron; It's necessary to keep the tip clean.
• Please wet the sponge before using.
• When the temperature is high enough, put the solder wire close to the joint, the solder will melt and flow freely.Please remove the solder wire when the tin is enough.
• Take away the soldering iron in a direction approximately 45°and power off.
• Don't pull the soldering iron tip outward and use it in that way, which will shorten the heating element life.

Notes:

1. Please be really careful when you are using the tools in avoidance of pricks or other injuries.
2. The iron heats up fast, so please select a suitable temperature. Working for long hours and high temperature may shorten its life.
3. Do not allow the iron to idle at operating temperatures for extended periods, This could burn the soldering iron and even other things.
4. Impurities in the metals are very easy to become oxidations in the process of soldering. And these oxidations will reduce soldering iron tip working efficiency so that requires more professional cleaning. Otherwise, Solder tip will not stick to tin. Please be careful to clean the soldering iron tip.
5. If you do not know how to operate the soldering iron tool, please operate under the guidance of the Professional!
