When using lead-free solder wire, you must be careful not to touch the road surface with your hand, and feel that the battery is charged, including the solder pen cover, which may cause an electric shock accident. Professional technicians should also wear protective clothing as much as possible during the operation, mainly because liquid organic solvents will be generated during the whole process of electric welding, and it is very easy to burn and blister without wearing protective clothing. Second, when using lead-free solder wire in the work area, do not let children get close to it, nor let people around who do not know the type of lead-free solder wire touch the solder wire. Whether it is electric welding or disassembly, it must be carried out by the professional staff of product development.

Secondly, after applying lead-free solder wire, it is necessary to cut off the main power switch in a timely manner. After the main power switch is turned on, the waterproof casing and other equipment cannot be quickly stored until they are cooled. When storing, you must also pay attention to the storage and dry space environment. Finally, the thick smoke formed by the lead-free solder wire during the whole process of electric welding is caused by the fusion of the solder wire in the flux paste and the high-temperature electric soldering iron. The solder wire additive contains rosin and chemical materials, which adhere to the human body for a long time. The fuselage will pose a safety hazard. It is strongly recommended to use an exhaust fan as much as possible to maintain air circulation.

When using lead-free solder wire in the work area, children should not be allowed to get close to it, and people around who do not know the type of lead-free solder wire should not touch the solder wire. Whether it is arc welding or disassembly, it must be carried out by the normative staff of product development. In addition to understanding this, welding process staff must also pay attention to the following aspects:

One of the common problems: the melting point of lead-free tin bars is very important, and there are many common melting points to pay attention to. The melting point is related to the metal composition of the solder bar. The melting point of the solder bar of tin alloy copper is 227 degrees, and the ambient temperature in electric welding is between 270 and 300 degrees.

The second common problem: lead-free solder bars are generally applied together with flux. Therefore, pay attention to the purchase of lead-free flux. It is necessary to choose a flux with good vitality, heat resistance, and no rubbing, which can also improve the efficiency of electric welding in electric welding work.

The third common problem: green lead-free solder wire furnace should be used. In the case of using lead-free tin wire, whether it is a solder wire furnace or a solder wire flux, it is necessary to choose lead-free, so that it can meet the requirements of environmental protection, and it is not necessary to use it together with a lead-containing furnace.

Secondly, after applying lead-free solder wire, it is necessary to cut off the main power switch in a timely manner. After the main power switch is turned on, the waterproof casing and other equipment cannot be quickly stored until they are cooled. When storing, you must also pay attention to the storage and dry space environment. The thick smoke formed by the lead-free solder wire in the whole process of arc welding is caused by the fusion of the solder wire in the flux and the high-temperature electric soldering iron. The solder wire additive contains rosin and chemical materials, which adhere to the human body for a long time. It will cause a safety hazard. It is strongly recommended to use an exhaust fan as much as possible to maintain air circulation.
