How to make a soldering iron on batteries with your own hands?

In the work of electromechanics or radio electronicsA soldering iron is one of the important tools. 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.

Battery powered soldering iron, collected by themselves, will be externallydiffer 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

Mini-soldering iron on batteries is intended for almost allkinds of electromechanical works. 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 forconducting electrical installation operations with small details. These may 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 a variety of 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

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.

Portable devices are also suitable foroperations 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 portablesoldering irons are considered their appearance. He will not compete with the stylish design of purchased devices. However, in many functional indicators such a tool will win.

Materials and Tools

To make mini hand-held soldering iron on batteries, some tools andequipment. It 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 work.

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 a thin sheet of copper was not found, withoutit can be dispensed with. 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. It is necessary to reel the foil carefully, not allowing its ruptures.

Creating a stinger

By creating a soldering iron from the batteries with their own hands, should start with the manufacture of its mainelement (sting). This requires a fairly thick piece of copper wire. Its end on the one hand must be sharpened to the optimum working angle. This procedure is carried out with a clerical knife. The edge of the wire can also be processed with a fine grain file.

The grinding form usually has the form of a screwdriver tip(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 in the process.

Electrical insulating mass

Considering, how to make a mini-soldering iron on batteries, attention should be paid to the manufacturing procedureelectrically 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 a pair of 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, on top of it you should pour a little powder from talcum powder. This will avoid sticking the solution.

The first stage of creating a heating element

Battery powered soldering iron has a special heating element. To make it, a tube prepared from copper foil is prepared on a previously prepared sting. 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 layerprepared in advance electrically insulating mass. The structure must be dried above a gas or electric burner. The temperature should be about 150 ° C. The layer of deposited material will be baked and hardened.

Then the heating elementWind a thin nichrome wire 0.2 mm in diameter. 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

Soldering iron cordless requires the use of a heating element withrequired technical characteristics. 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,the end of the 6 cm long wire must be inserted behind 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 is the procedure for making the heatingelement is almost complete. 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. It must be carefully considered, how to make a soldering iron out of a battery and presented above improvised means.

The ends of the heating element must be connected tobatteries. 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.

User Reviews

Homemade soldering iron on batteries, reviews which is provided by users,is made quickly enough. There are other methods for creating the equipment. The procedure considered above is one of the simplest. Therefore, it is suitable even for a beginner master.

Creating a portable mini soldering iron will costrelatively inexpensive. If all the materials are at hand, it will not be difficult to assemble the instrument. However, for those who do not have enough time or skills, it is recommended to buy a ready-made soldering iron in a specialized store.

Users note that when allpoints of creation of the portable tool, the finished product on an order differs from purchased analogues. The device will not have an elegant appearance, but its functionality, durability and quality will be higher than the average models of the equipment on sale.

Materials for the stand

Homemade battery powered soldering iron will be more comfortable in operation if availablecoasters. 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, as well as a bracket of W-shaped configuration.

Table on which to buildstand, it is necessary to make a bed (it is 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

By creating battery powered soldering iron, it is necessary to properly assemble and support for it. The metal box must be secured with self-tapping screws on narrow slats of plywood. Fastening elements cut into the side walls.

The created design is necessary firmlyfix on a wide strip of plywood. W-shaped staple from 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 a plywood with a bracket it is necessary to mount a number fromwooden 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.

After reviewing how to create battery powered soldering iron, everyone can independently assemblesimilar equipment. If there is enough free time, even a novice wizard will be able to perform this procedure. This will create a high-quality device. It will function long and efficiently.
