How to use the new soldering iron? How to use a new soldering iron correctly the first time

The method of using an electric soldering iron is to plug the electric soldering iron into a power supply, wait for the electric soldering iron to heat up, and then heat the solder joint. When there are many solder joints, auxiliary tools are required. Use a solder extraction device.

The soldering iron heats the solder joint, and after the solder melts, align the suction device at the solder joint and press the button to suck away the solder. Soldering irons are the most commonly used soldering tools. We use a 20w inner hot soldering iron.

Before using the new soldering iron, polish the sonotrode with fine sandpaper, heat it with electricity, dip it in rosin, and then contact the wire with the edge of the sonotrode to evenly coat the sonotrode with a layer of tin. In this way, welding can be facilitated and oxidation of the surface of the sonotrode can be prevented. If the old sonotrode is heavily oxidized and blackened, the surface oxide can be removed with steel to expose the metallic luster, and then tinned before it can be used.

The soldering iron should use a 220V AC power supply, and special attention should be paid to safety when using it. The following points should be done seriously:

It is best to use a three-pole plug for soldering iron plugs. Ground the enclosure properly.

Carefully inspect the power plug and cord for damage before use. And check whether the sonotrode is loose.

When using the soldering iron, do not strike too hard. Prevent falls. When there is too much solder on the sonotron, it can be wiped off with a cloth. Do not litter to avoid burning others.

During the soldering process, the soldering iron should not be left around. When not soldering, it should be placed on a soldering iron holder. Be careful not to put the power cord on the welding head to avoid burning out the insulation and causing an accident.

After use, cut off the power supply and unplug the power plug in time. Once cooled, return the soldering iron to the toolbox.

2.Solders and fluxes.

When soldering, solder and flux are also required.

1) Solder: The solder wire of rosin core is generally used for welding electronic components. This solder wire has a low melting point and contains rosin flux, making it very convenient to use.

2) Flux: The commonly used flux is rosin or rosin perfume (rosin dissolves in alcohol). The use of flux helps to remove oxides from the metal surface, facilitating soldering and protecting the sonotrode head.

Solder paste can also be used when soldering large parts or wires. However, there is a certain corrosiveness, and the residue should be removed in time after welding.

What you need to prepare: solder wire, rosin, soldering iron.

1. First of all, take out the materials and tools shown in the figure below and set aside.

2. Next, power on the soldering iron, and wait until the temperature of the soldering iron reaches the rosin and solder, as shown in the figure below.

3. Next, the thread that needs to be soldered is dotted with rosin and solder, as shown in the figure below.

4. Then quickly solder the wire to the electrical components as shown in the figure below.

Method:

The new electric soldering iron can not be used immediately, you need to coat the soldering iron tip with a layer of solder first, the method is: file the soldering iron tip with a file, press the power supply, and apply rosin to the soldering iron head when the temperature gradually rises; When the rosin is smoking and the soldering iron tip begins to melt the solder, put the soldering iron tip on sandpaper with a small amount of rosin and solder and grind it to all sides, so that the soldering iron tip can be coated with a layer of solder.

The soldering iron should use 220V AC power supply, and special attention should be paid to safety when using it. The following should be done conscientiously:

It is best to use a three-pole plug for the soldering iron plug. Make the enclosure properly grounded.

Before use, the power plug and power cord should be carefully checked for damage. And check if the soldering iron tip is loose.

When using an electric soldering iron, do not strike it too hard. To prevent falls. When there is too much solder on the soldering iron tip, it can be wiped off with a cloth. Do not throw it indiscriminately to prevent burning others.

During the soldering process, the soldering iron should not be left around. When not soldering, it should be placed on a soldering iron holder. Note that the power cord should not be placed on the soldering iron tip to prevent accidents from burning the insulation.

After use, the power should be cut off in time and the power plug should be unplugged. Once cooled, retract the soldering iron into the toolbox.

First of all, when the new electric soldering iron is used for the first time, when it is heated to the point that it can start to melt the solder wire, it is necessary to put the solder wire on the soldering iron tip to melt the solder on the surface of the soldering iron tip to prevent the soldering iron tip from oxidizing and not soldering. You can also apply a little solder paste or rosin. After this treatment, the soldering iron tip is easy to tin, and there will be no "solder ball" falling off in a flash.

Secondly, the part to be welded, first do deoxidation treatment, that is, use a knife to scrape the oxide layer on the surface of the welded surface, apply a little solder paste or rosin, and then put the solder wire and soldering iron tip on the welding part at the same time, and after melting a little solder wire, you can solder very well.

1.Turn on the power switch of the adjustable temperature soldering iron.

2.Set the temperature to between 360-400 (around 350 for new buyers)3After the soldering iron reaches the set temperature (the indicator light will flash), add tin to the soldering iron4

Hold the handle of the soldering iron in your right hand and place the tip of the soldering iron on the foot of the component to be soldered5After the solder is melted, hold the tweezers in your left hand and remove the components of the soldering iron

1.Before use, moisten the sponge so that you don't drip water down by gently picking up the spongeThe temperature is set between 360-400.

3.The soldering iron cannot be bumped, and the heating chip in the handle is easily damaged by knocking4During the heating process, the tip of the soldering iron should not touch the plastic, rubber and other compounds, let alone your own or others' bodies.

5.After each use, add tin to the soldering iron tip, and then put it on the soldering iron rack and turn off the power, which can effectively protect the soldering iron tip from oxidation and prolong the service life of the soldering iron.

Is there a problem with the temperature of the soldering iron, is there a thermostat, and there is a choice of tin wire containing rosin dxt-n5, if it turns black and can't get on the tin, please clean it with a cleaning agent or manually before use.

Prepare a small piece of sandpaper and solder, plug the soldering iron into the power supply, heat it, and hang the tin while sanding on the sandpaper, you can take the tin for sanding until the soldering iron tip is completely coated with tin. Unplug the power supply. It's no problem to use it later.

Of course, when the soldering iron is not in use, it is necessary to unplug the power supply in time, do not heat it for a long time, and it is easy to burn the soldering iron tip to death, and it needs to be reprocessed.

There is an oxide layer on the head of the new soldering iron, file it off with a file, expose the smooth copper surface, stick the rosin while heating, hang the tin after the temperature, dip it in the rosin when you usually use it, and keep the soldering iron tip not oxidized, otherwise it is difficult to melt the tin, and it is not easy to stick to the tin.

The new soldering iron tip needs to be polished.

Flying wires can be used to connect.

How to use an electric soldering iron:

1. Pretreatment of soldering iron tip and components.

Use a small iron sheet to clean up the dirt on the head of the soldering iron, immediately point it in the rosin, the effect is not to let the high-temperature copper head quickly nurture, and then coat it with solder wire to become a shiny finch with a coarse and respectful tin appearance.

2. Pre-welding. Before soldering, the wires and points to be soldered should be pre-tinned, that is, the lead wire of the component to be soldered or the conductive soldering part should be wetted with solder in advance, also known as tinning, tinning, tinning, etc.

3. Soldering iron temperature control.

The temperature of the soldering iron is set to 350, 350 can ensure the temperature required for soldering, and the temperature exceeds 400 It is easy for the soldering iron tip to oxidize.

4. The soldering iron tip is first entered and then sprinkled.

First of all, the angle between the soldering iron tip and the work surface, about 45 degrees, point into the solderment (component), after about 1 second, hold the solder bench empty wire in the left hand, and also point in at a 45-degree angle on the opposite side of the component, wait for the tin on the component to melt, first scatter the tin wire, about 1 second, and then remove the soldering iron tip.

Here's how to use it:1. Plug the soldering iron into the power supply to preheat.

2. Put the soldering iron after the preheating is completed on the rosin and dip it in a little Zhizheng rosin.

3. Put the tin bar on the soldering iron head and apply the solder evenly on the soldering iron head, so that the soldering iron tip is evenly coated with a layer of tomato and tin.

4. At this time, the electric soldering iron can be directly used for welding, and the tin is evenly spread on the welding head with an electric wire while feeding the wire by hand during welding.

5. If you see some soldering impurities on the soldering iron tip, you can put the soldering iron tip on the soaked sponge to clean up.

6. Put the used soldering iron on the shelf and wait for it to cool down before putting it away.
