Why isn't the electric iron hot? What's the reason for it? Can you fix it? How do you fix it?.
What kind of electric iron are you using? It can be repaired. No fever, only the heater core is broken, or the battery is dead
Electric iron is divided into two types of external heat and internal heat, the general power of the external heat is larger.The internal electric iron is smaller and cheaper. In general, electronic production uses 20W-30W's internal heating electric iron. Of course, there is a 50W external hot electric soldering iron can be prepared. The heating electric iron has higher heating efficiency, and the replacement of the soldering iron head is more convenient.The electric iron is used for soldering, for ease of use, usually made of solder wire, solder wire in general contain rosin flux. Solder wire uses about 60% tin and 40% lead to synthesize, melting point is lower. (Bitbaby has a good habit of washing hands every time he finishes. Lead is not a good thing, but rosin is used to it very much. -)Rosin is a kind of soldering flux, which can help welding. The people who play the erhu must have it. They can also be bought at the drugstore. Rosin can be used directly, or can be configured as a rosin solution, that is, to crush the rosin, into a small bottle, and then add alcohol, stir well. Note that alcohol is volatile, after use, remember to tighten the bottle cap. A small piece of cotton can be placed in the bottle and used to be clamped out of the printed board or component.Note that there is a solder paste on the market (with that, it's a kind of welded oil) with corrosive things, is used in industry, is not suitable for making use of electronic. There is also commercially available pine perfume, not the rosin solution we use here.Electric irons are held in the hands, pay attention to safety when using. The new electric iron must first check the resistance between the plug and the metal case with a multimeter. The multimeter indicator should not move. Otherwise, it should be thoroughly checked.
Electric iron: an electronic manufacture and maintenance of electrical tools, usually by the iron head, iron core, shell, wood handle, power lead, plug and other parts, the main purpose is welding components and wires.The working principle of the electric iron: after the power is put on, the heating wire is passed through the resistance wire of the iron core, and is passed to the iron head, and the soldering tin is melted by the iron head.Electric soldering iron is not hot, the main reason may be the iron head in the resistance wire burning, this is the electric irons in the wearing parts, change a soldering iron core can. But also can not rule out the power line, plug fault. Therefore, when the electric iron is not hot, you should check the power plug and power cord with the multimeter, and then check the iron core after removing.
