For home appliance maintenance personnel and electronic enthusiasts, electric soldering iron is one of the necessary welding tools in maintenance work, and its quality and quality directly affect the efficiency of maintenance work. we know. In daily maintenance work, the electric soldering iron is often in a long-term energized working state, and the soldering iron tip is seriously oxidized due to overheating. The lack of tin on the tip of the soldering iron makes soldering difficult and reduces work efficiency. Once the tip of the soldering iron is severely oxidized. No matter what method you use, it is difficult to make it tinned. Although various countermeasures have been introduced in the newspaper, in fact it cannot completely solve the problem. Sometimes it is temporarily resolved. But after a while, the tip of the soldering iron was still oxidized severely. To this end, the author read the information. Hope to find a way to prolong the life of the soldering iron. First of all, the author tried the method introduced by the newspaper, that is, installing a diode and a switch on the power supply of the electric soldering iron. The circuit is shown in Figure 1. When the electric soldering iron is powered on, the switch in Figure 1 is in the normally open position. Due to the connection of the diode, the electric soldering iron works in a half-wave rectification state, and its power is about half of the usual power. overheated oxidation. While working, just press the switch. The electric soldering iron works at the rated power, and its temperature will rise rapidly to facilitate welding. The disadvantage is that the switch needs to be pressed every time it works, so it is always inconvenient to use. If the circuit is changed to the circuit in Figure 2, the effect is slightly better.
The cylched dim ond defnyddiau a tymheredd switsh yn lle o an cyffredin switsh, a y tymheredd switsh yn sefydlog ar t t y hir y soldering haearn yn ar y tenau alwminiwm plate, unwaith tymheredd tymheredd cyrraedd 100 gradd % 2c y tymheredd switsh bydd fod datgysylltiedig. Yn hyn amser, yn unig y deuod yn energized, a y trydanol sodro haearn gwaith yn A hanner ton wladwriaeth. Lleihau y pŵer y y soldering haearn i atal y tip o y sodro haearn o gorboethi. Mae'n hefyd anuniongyrchol prolongs y gwasanaeth bywyd y trydan sodro haearn. Mae yn angen i wasg y newid pan gweithio yn yr un amser.
AlThough y gwasanaeth bywyd y trydan soldering haearn can fod ymestyn ar ôl addas, y anfantais yw mae'n Ni all fod weldio gyflym, gwneud mae'n annerbyniol i y mwyafrif o cartref offer cynnal a chadw personél a electroneg enthusiasts. Can chi dod darganfyddiad a ateb gwell Y awdur cyntaf y egwyddor gweithio y cyson tymheredd trydanol soldering haearn. Mae'n egwyddor gweithio yn yn uchod enghraifft. Ar ôl cyrraedd y set tymheredd, y trydan sodro haearn troi oddi ar y pŵer supply, a unwaith y tymheredd diferion, mae'n troi ar eto. Y pŵer cyflenwad keeps yn yn regulator. Can hyn problem yn datrys gan addasu y foltedd? Ar gyfer hwn rheswm, yr awdur cyntaf meddwl o y electronig foltedd rheoleiddiwr. Ar ôl profi, yr effaith o defnyddio y electronig folt rheoleiddiwr i addasu y trydan sodro haearn yn yn yn wir yn well.
