How to weld: 1. When the electric iron is first inserted, it will come out from the tip. The smoke will stop in a short time, the smoke will never appear again. 2. Prepare solder and soldering iron. In particular, the tip must be kept clean, where the solder should be coated. 3. When welding, when the tip is covered with oxide and black, you need to rub in the rosin rub and use solder wire to it on the tin to keep the tip of the tip of the 1 / 4-1 / 2 area is bright Of the tin state. 4. Use soldering iron to heat the welding parts, such as PCB wires and pads, and keep the welds evenly heated. 5.60W Adjustable thermo-soldering iron, the temperature should be adjusted to 200 ° C (392 ° F) when welding the patch element, and the temperature is adjusted to 450 ° C (842 ° F) unless a larger discrete element is to be welded. 6. Such as a long time welding patch components of the PCB board, should use 30W of soldering iron, such as welding discrete components of the PCB board, should use 60W electric iron. 7. It is feasible to use two electric soldering iron (60W soldering iron to adjust to the highest temperature) to weld the super-large solder joint. 8. Do not pull out the 30W soldering iron tip and use it in this way, which will shorten the service life of the heating element. 9. High temperature sponge to add water to use. 10. When the temperature is high enough, place the wire at the joint and the solder will melt and flow freely. 11. Electric iron connected to the power supply, should be placed on the electric iron frame, do not mess up, so as to avoid accidents. Double iron can be placed at the same time two electric soldering iron. Electric iron power, should be fully cooled, usually 20 minutes after the collection.
