No matter how long it takes for the solder iron to heat up and perform, it will still be in fine shape.

Turn on the electricity and heat for about 3 minutes, the solder can be melted and it can work. The electric soldering iron cannot be fired empty, it can work continuously.

1. The electric lipire fier is divizat în două tipuri: extern încălzire tip și intern încălzire tip:
(1) The external heating electric solder iron is composed of a solder iron tip, a soldering iron core, a shell, a wooden handle, a power lead, a plug and other parts. Because the solder iron head is installed inside the soldering iron core, it is called an external heating type electric soldering iron. The solder iron core is the key component of the electric soldering iron. It is is the key component of the electric soldering iron. It is format de înfășurare încălzire sârmă în paralel on a gol porțelan tub. A mica foaie în mijloc este izolat% 2c și două fire sunt trase afară la conectați cu 220V AC alimentare alimentare.

(2) The internal heating electric soldering iron is composed of a handle, a connecting rod, a spring clip, a soldering iron core, and a soldering iron tip. Because the soldering iron core is installed inside the soldering iron head, it heats up quickly and has a high heat utilization rate. Therefore, it is called an internal heating type electric soldering iron. The commonly used specifications of internal heating electric soldering iron are 20W and 50W. Due to its high thermal efficiency, a 20W internal heating soldering iron is equivalent to a 40W external heating soldering iron. The rear end of the internal heating type electric soldering iron is hollow, used to be sleeved on the connecting rod, and fixed with a spring clip. When the soldering iron tip needs to be replaced, the spring clip must be withdrawn first, and the front end of the soldering iron tip should be clamped with pliers. Pull it out slowly, remember not to use too much force, so as not to damage the connecting rod.

2. In the maintenance of mobile phones, the components on the circuit board are often replaced, requiring the use of an electric soldering iron, and the requirements for it are also very high. This is because the components of the mobile phone adopt the surface mount process, the components are small in size, highly integrated, the printed circuit is fine, and the pad is small. If the soldering iron is not selected properly, it is easy to cause human faults during the soldering process, such as false soldering, short circuit or even soldering of the circuit board. Therefore, it is necessary to use a high-end soldering iron as much as possible, such as a constant temperature and anti-static soldering iron. In addition, some large devices such as shielding covers need to use high-power electric soldering irons, so an ordinary 60W or more thick-tip electric soldering iron should be prepared.
