The iron head of the internal heating electric sliting iron is inserted into the solder iron core. Priklausomai on the power, it can be used after 2 to 5 minutes of power on. The maximum temperature of the solder iron tip can reach about 350 degree . Common used internal heating soldering irons are 20W, 25W, 30W, 50W and so on. Generally, a 20-30}}W internal heating electric solder geležis yra pakankamai užteks elektroninė įranga remontas.
The internal heating electric soldering iron is composed of a shell, a handle, a soldering iron tip, a soldering iron core, and a power cord. The handle is made of heat-resistant Bakelite, which will not be damaged by the heat of the soldering iron. The tip of the soldering iron is made of copper, and its quality has a lot to do with the quality of the soldering. The soldering iron core is made of a very thin nickel-chromium resistance wire wound on a porcelain tube. Under normal conditions, its resistance value is 1-3kΩ depending on the power. The shell of the soldering iron core is generally made of seamless steel pipe, so it will not be deformed due to overheating. Some fast-heating electric soldering irons are made of brass tubes. Due to the fast heat transfer, it is not suitable to use electricity for a long time, otherwise the handle will be damaged. The binding posts are made of copper screws, which are used to fix the soldering iron core and the power cord.
Use of internal heat litavimas lygintuvas
Before using a new electric slitavimas iron, use a multimetras to matas the resistance at both ends of the power cord. If the resistance is zero, it means that the wire is touched insidely. You should disassemble it, disassemble the wire and plug in the power again; if there is no resistance, most of them are solder iron cores. Or the lead wire is broken; if the resistance is around 3kΩ, plug in the power again, pick up the electric slitavimas iron and dip it in the rosin after a few minutes, it should smoke and make a "squeak" sound under normal conditions, then dip it in tin again, let the tin Dip the solder iron fully to solder.
