In the work of electromechanics or radio electronics, one of the important tools is a soldering iron. It can be made in the form of a handle. Such devices are sold in specialized stores. If for some reason you can not use an ordinary soldering iron, you can use a portable model. And you can do it yourself.

, собранный своими руками, будет внешне отличаться от покупного инструмента. A battery-powered soldering iron , assembled by one's own hands, will differ from the purchased instrument. However, in terms of functionality, it will not be inferior to the models of equipment presented on the market. How to create such a soldering iron, it will be interesting to know every electrician.

Purpose of portable soldering iron

предназначен для проведения практически всех видов электромеханических работ. Mini-soldering iron on batteries is designed for almost all types of electromechanical work. If other types of such equipment have a clear specialization, this device is capable of performing many different operations. So, with its help it will be possible to solder the wires, perform work with the radiator, restore the function of the network connector, and so on.

Especially convenient is a portable soldering iron for conducting electrical installation operations with small details. These can be microcircuits, small electronic devices (clocks, timers, etc.). Also it is used when creating self-made chargers for phones, tablets and other gadgets. Radio electronics also performs many operations with a small portable soldering iron.

If you produce the equipment yourself, you can achieve a high quality soldering iron. Also the cost of a portable soldering iron will be much less than that of the purchased models.

Features

будет иметь небольшую мощность. The self-made soldering iron on batteries will have a small power. This figure will not exceed 40 watts. However, for full-fledged work this is enough. It can be used in a small workshop, where there is no place for the use of a stationary tool. Such equipment is useful in conditions where it is not possible to connect the soldering iron to the power grid.

Also portable devices are suitable for operations with sensitive parts and elements of various devices. Soldering irons of this type are used in their work by jewelers, watchmakers and even dentists. The battery charge is usually enough for more than 300 rations.

The only drawback of self-made portable soldering irons is their appearance. He will not compete with the stylish design of purchased devices. However, in many functional indicators, such an instrument will win.

Materials and Tools

, потребуется подготовить некоторые инструменты и оборудование. To make a mini-soldering iron on batteries with your own hands , you will need to prepare some tools and equipment. This will be a simple device that will be useful in the process of soldering wires, microcircuits, etc. The power of it will be about 25-40 W. To create a tool yourself, you need the following:

• pliers;
• Stationery knife and scissors;
• Copper wire;
• Foil from copper;
• Nichrome thread ;
• insulating tape;
• Metal cavity for the body of the electric heater;
• Silicate adhesive;
• Handle of wood or plastic, resistant to heat;
• talc;
• 2 finger batteries.

After the preparatory phase, you can start working.

All its stages must be carried out in strict accordance with the instructions of professional masters. In this case, the quality of the soldering iron will be high.

If you can not find a thin sheet of copper, you can do without it. It is replaced with foiled fiberglass. To do this, the text sheet needs to be heated with an iron. The edge of the foil should be screwed onto the rod. As the iron moves along the plane of the sheet, the metal sheet is wound in the form of a tube. The foil needs to be rolled up carefully, not allowing its ruptures.

Creating a stinger

следует начать с изготовления его главного элемента (жала). When creating a soldering iron from batteries with your own hands, you should start with the manufacture of its main element (sting). This requires a fairly thick piece of copper wire. Its end on the one hand must be sharpened to the optimal working angle. This procedure is performed with a clerical knife. The edge of the wire can also be processed with a fine grain file.

The form of sharpening usually has the form of a tip of a screwdriver (like a scapula). The working surface has a dihedral configuration. Its bevel should be about 45 °. Typically, the thickness of the sting is about 5 mm in the area of the working surface.

If you want to create a miniature soldering iron, the thickness of the represented element can be only about 2 mm. Such a needle stinger should be sharpened in the form of a cone. If special work is required, the wire size may be different. Also, the shape of the sting may be different. For example, the point may have any configuration or thickness.

The work surface must be coated with a thin layer of solder. Over time, this layer will have to be applied again during operation.

Electrical insulating mass

следует уделить внимание процедуре изготовления электроизолирующей смеси. Considering how to make a mini-soldering iron on batteries, you should pay attention to the procedure for manufacturing an electrically insulating mixture. This requires glue (silicate). It is mixed with talc powder. Must be a mass with a viscosity similar to liquid sour cream. This solution must be applied using tweezers to the cylindrical part of the tip. This action can also be performed with an inert plate of sufficient rigidity.

A mixture of talcum powder with a silicate adhesive is very sticky. This complicates the work a little. Therefore, it is necessary to pour a little of talc powder on top of it. This will avoid sticking the solution.

The first stage of creating a heating element

обладает особым нагревательным элементом. A soldering iron from the batteries with its own hands has a special heating element. To produce it, a copper foil tube is put on a previously prepared stinger. Its length should be 3 cm. A sting should leave the tube. Its open part should not be more than 1 cm.

This construction should be covered with a thin layer of pre-prepared electrically insulating mass. The structure must be dried over a gas or electric burner. The temperature should be about 150 ° C. The layer of deposited material will be baked and hardened.

Then a thin nichrome wire 0.2 mm in diameter must be wound on the heating element. It will take about 35 cm. A spiral of wire is wound very carefully. The coils must fit tightly together.

The straight ends of the wire are outside the heating element. One of them should have a length of 3 cm, and the other - 6 cm.

The second stage of creating a heating element

нуждается в применении нагревательного элемента с требуемыми техническими характеристиками. A wireless soldering iron on batteries requires the use of a heating element with the required specifications. The quality of this part will depend on the work of the equipment. After winding, it is covered with an electrically insulating mass. The drying process over the burner is repeated.

When the solution of the glue with talc will dry, leave the end of the wire 6 cm long by the body of the heating element. It is tightly attached to the body of the tube. Then again an electrically insulating layer is applied. The drying procedure is repeated.

This completes the procedure for manufacturing the heating element. The only thing else the master has to do is cover the outgoing ends of the wire with an electrically insulating mixture. It is applied to the wire half the length. The solution is then dried over a burner.

Assembling the instrument

There is a certain sequence of assembly of pre-fabricated portable equipment. и представленных выше подручных средств. It must be carefully considered before making a soldering iron out of a battery and the above improvised means.

The ends of the heating element must be connected to the batteries. This can be done with two small wires of copper. Place joints with tape. The connected batteries should be placed in a prepared housing. It can be wooden or plastic.

To work with such a tool it was more convenient, you can make a stand for it yourself. Before you start, you need to check the build quality. This model can be done with a power cord. In this case, a 220 / 12V step-down transformer is required.

To produce it, you need a metal box or lid, as well as pieces of rectangular plywood. It is necessary to prepare wooden beads, screws, nails, and also a bracket of W-shaped configuration.

The table on which the stand will be assembled must be covered (recommended by the newspaper). From the plywood you need to cut the slats. One of them will be wide, and the other two narrow. The first bar will serve as the base of the stand. Two narrow strips of plywood are necessary for fixing the box.

If desired, you can drill holes in one of the slats. In them jars with improvised materials (flux for soldering, rosin, solder) are inserted.

Assembling the stand

, следует правильно собрать и подставку для него. When creating a soldering iron on batteries , it is necessary to properly assemble a stand for it. The metal box must be secured with self-tapping screws on narrow slats of plywood. Fixing elements cut into the side walls.

The created design must be firmly fixed on a wide strip of plywood. W-shaped staple of the tin is attached opposite the holes for jars with improvised materials. Here in the process of work you can put a soldering iron.

Under the plywood with a bracket, you should mount a row of wooden beads. These are the stiffeners. In the iron lid should put a sponge of special cellulose material. It is required during the soldering process to clean the sting.

Stand for the soldering iron is ready. It can be installed jars with rosin and solder. In this case, using a self-made soldering iron will be much more convenient.
