How to modify the ordinary iron iron into energy saving, anti-oxidation of electric soldering iron ---- electric iron transformation

How to modify the ordinary electric soldering iron into energy-saving, anti-oxidant electric iron, iron iron transformation Keywords: electric iron Be Circuit and Working Principle Introduction Rectifier Diode (1N4007): 220V AC Half Wave Flow into 100 V Pulse DC. Regulatory diode (1 N4727): protect the light-emitting diode to keep the working voltage at both ends of the light emitting diode and normal illumination; if not connected, the working time is long, the light-emitting diode will burn down due to too high voltage. LED (LED): Indicates that the circuit is in a welding state or to be welded. Normally closed switch (SB): The state of the switching circuit, the circuit is in the welding state, and the circuit is in the state in which the circuit is off. Characteristics of the circuit 1, longevity electricity. Welding status, 220V AC electricity is added to the soldering iron core, so that the soldering iron is in a very good welding state; if only half of the voltage is added to the soldering iron, not only avoiding the ironing iron, but also makes the soldering iron are always in pre-pre-previse Thermal state (practice proves that the soldering iron in the preheated state can be in the welding state, does not affect the use effect), both longevity and power saving. 2, simple and affordable. "Energy Saving" electric soldering is required to add four common components on the basis of the original iron (diode 1N4007, light-emitting diode, normally closed switch and regulator diode). The modified cost is low, add up to 0.5 yuan. 3, convenient and safe. The biggest advantage of the "energy saving" soldering iron we have is that the energy saving switch does not need to be controlled. It is "automatic". As long as the soldering iron is inserted on the soldering iron rack, it can realize the switch automatically and disconnect. When you pull out the soldering iron, you can Automatic closure of the switch. In indication with a light-emitting diode, indicating that the soldering iron is in a welding state or to be welded. Simple energy-saving electric soldering iron has solved the problem of easily oxidation of the soldering iron, and reaches the purpose of longevity, energy saving.
