Q: Using a 35W constant temperature electric iron, heated iron head black, with rosin, then solder, solder coating is not on, have the ball dropped, where operation mistake, and ask whether the new iron head sanded ah?
The new iron head has an oxide layer, with a file away, exposed copper surface smooth, heating and sticky rosin, to the temperature after hanging tin, usually used frequently with rosin, keep tip oxidation, or tin melting difficult, not easy to stick tin.
Q: Can spring be welded with electric iron?
The spring is made of special steel, like electric iron can only be used for soldering and other low melting point and low intensity, and the spring is also very difficult to weld by other methods
Q: Attention to the general use of electric iron?
First, small power, internal heating type electric iron1, after the purchase, first check the performance: the electric heating core is broken; the internal electric wire and the power input line is connected. Then it is, whether flying thorn; power line meets the requirements, whether the breakage of the power plug is intact;Check the insulation between the power plug and the iron head by the high resistance gear of the meter or multimeter before power on; check the power supply plug with the multimeter resistance file; tighten the thread arm wire on the handle.2 、 electrify test: check whether the temperature rise is qualified.3, in the process of using a power socket must be connected in distribution box with security measures; the operator seat be paved with insulating sheet sufficient area; the power plug to plug the power, do not pull the power line; power line should be avoided hanging; use special spiral casing type iron frame. To prevent the loss caused by bad goods even after hot combustion; non percussion on the body, prevent damage to electric iron, resulting in safety hazards; long time disabled should promptly unplug the power plug or cut off the total power.4, regular regular performance and safety performance inspection, unqualified parts should be replaced in time, and even the electric iron scrap.Two 、 high power and external heating type electric ironIn addition to the above contents, it is forbidden to burn personnel and articles to prevent fire.Three, supplement:1, conditional units and individuals need to configure isolated transformers.2, please use battery electric iron when there are special requirements.There are many kinds of hand electric irons, and the difference is great. In short, the security content is nothing more than personal safety, tool security, product safety and environmental safety.Don't laugh at inappropriate.
Q: Why isn't the electric iron hot? What's the reason for it? Can you fix it? How do you fix it?.
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.
Q: How much can I pay for it? Is there any hardware store?
The pad is a manual tool commonly used in electronic welding processes. It is melted by heating the solder wire, so that the two workpieces are soldered together. Compared with the ordinary electric iron, the thermostat has the following advantages:1, limitations are smallThe iron head has a pointed head, a horseshoe head and a knife first class, and each has its own limitations in its use. For example, the pointed iron is suitable for welding smaller components, and the head iron is suitable for welding the chip and chip. The welding table can change the soldering iron head freely according to the welding requirement.2, high efficiencyThe efficiency of the constant temperature welding table is relatively high, and the thermal efficiency can reach 80% or so, which is much higher than that of a common electric iron3, low energy consumptionWhen the constant temperature welding table reaches the set temperature, the heating is not continued, and the energy consumption is correspondingly reduced. In other words, the same welding effect, welding platform less power, 4, fast temperatureThe temperature of the welding table is faster, the waiting time of the welding is shortened, and the work efficiency is improved by 5, and the service life of the consumables is longThe temperature of the welding table can be controlled and can not rise infinitely, so the life of the iron head and the life of the heating core are longer, 6, and the safety is strongThe handle voltage of the welding table is only 24 volts of AC. It belongs to the safety voltage, so the electric shock will not happen. Besides, the welding table has the function of removing static electricity, and can effectively avoid the damage of the electrostatic component when welding.
Q: I can't solder it. It doesn't stick together. It keeps getting old. It rolls on it, but it doesn't stick
Electric iron temperature should be higher first, power should be large, back to temperature faster. Otherwise, that's your situation,Secondly, the line to tin, welding position should first point tin,If the solder joint is stainless steel or copper plate, the first if iron is put up, to be weld preheating 3~5 seconds, and then on the point of flux, and then the tin, determine the good, wait a few seconds and then cooling, welding line, so there is no problem
Q: When the welding is done, where is the head of the soldering iron, where the original pin is attached to the circuit board or on the original pin? Then the tin bar is placed on the head of the soldering iron. After melting, he rolls onto the circuit board Total sense of mastery skills
The iron head put the position of the connection in the original pin and circuit board and solder wire (preferably used) is placed on the iron head waiting for him to melt after rolling to the circuit board, because solder wire inside rosin flux, solder joint welding end so smoothly, and then cut off the excess pin can be. Two question: how to suck the tin of the interface? Put on tin suctioner ready to use electric iron? Or reverse the order? Should be the one hand iron hand ready to see the soldering tin suctioner, tin suctioner immediately sucked out of solder, both the first of which one will make the solder cooling wash off or suction is not clean
Q: People engaged in the maintenance of electronic factories often contact electric irons and welding. They will smoke a lot of solder wire. What harm do they have to the body? What fruit can be eaten to help rid the body of toxic smoke?
Most importantly, there is rosin in the solder wire, which contains benzene and benzene is a carcinogen
Q: The electric iron should heat the pad. Do the solder wire melt on the pad or solder the solder on the soldering iron to the pad?
If the pad is a workpiece, the pad should not be heated, otherwise the solder will not solidify before the pad cools and will lead to solder lossThe correct way is to should be in soldering iron head melting, welding parts will need to apply the soldering iron head, or soldering iron head and at the same time in the welding position. If the workpiece is too large, the heat is not easy to gather, the occurrence of solder early solidification, must use the power of electric iron more.
Q: Can electric irons weld stainless steel?
The electric iron used for soldering, welding of copper and zinc silver, with hydrochloric acid or zinc chloride flux free soldering iron to do strong, but it is difficult to weld stainless steel.
