3 simple ways to make the soldering iron from scrap materials

idea №1 - Using a resistor

The first and most simple technology of manufacture of the electric soldering iron with his own hands - with the use of a resistor.The device is designed to operate at a voltage of 6 to 24 volts. In order to make their own tools, you will need the following materials:

• resistor with characteristics: resistance is 20 ohms, the power of 7 watts.
• Textolite plate for the manufacture of a convenient handle.
• Two copper rods of various sections.One that thicker is selected strictly on the inner diameter of the resistor.The second should be thinner for ease of soldering chips little sting.
• One bitten off ring springs (will serve as a clamp) screw and washer.All accessories you can see in the photo below.

order to make the soldering of the resistor in the home, you must perform the following steps:

1. The end of thick copper rod have to drill a hole and drive a screw thread.It is also necessary to cut a groove under retainer, which in our case is a ring spring.
2. from the second end of the drill hole diameter as that of wire rod, which will act as the tip soldering iron mini.
3. All the elements of the rod you need to collect in one piece, as shown in the photo.
4. resistor is prepared for fixing the soldering tip to be inserted and fixed rear cog hockey.
5. From textolite plate need their own hands to make a comfortable handle with a seat under the resistor and wire.
6. to the conclusion of the heater must be connected to the power cord.
7. Ready homemade twisted soldering and checked.

draw your attention to the fact that such a portable gun can be easily soldered chips and even make a charger for the car battery by hand.Work it can not only from the power supply, but also on the batteries.On the forums, we met a lot of feedback, where the homemade version was connected from the cigarette lighter 12 V, which is also very convenient!

idea №2 - The Second Life of a ballpoint pen

Another unusual, but at the same time a simple idea to make a soldering iron with their hands out of scrap materials.In this case, we again useful resistor, but in this case no longer SEW (as in the previous embodiment), and IFL.

So, first you have to prepare the following materials:

• Pen simplest design.
• resistor with characteristics: resistance is 10 ohms, the power of 0.5 watts.
• double-sided PCB.
• copper wire 1 mm in diameter.
• steel wire with a diameter less than 0.8 mm.Now it should be noted that the steel should take the form and at the same time not to be a soft, further understand why.
• wires to connect to the network.

Make a soldering iron of the handle at home is quite simple, just follow these steps:

1. remove paint from the resistor surface.If the paint is removed bad, connect the product to a regulated power supply and a little heat.
2. From keg leaves 2 wires, one of them cut off and drill the hole with a copper wire (diameter 1 mm).To the wire does not come into contact with a cup (that it is necessary to avoid), make a countersink drill bit thicker, as shown in the photo below.In addition, you need to make a small propyl for tokovoda right on the cup resistor.
3. Arch steel wire shaped handles with fastening in the form of a ring with a diameter like a drunk on a cup.
4. Carefully saw out of the double-sided PCB board with his hands, exactly the same as shown in the example in the picture.
5. Next you need to assemble a homemade soldering of a pen, it should not cause difficulties.
6. remains a delicate thorn in the seat.For copper wire is not burned a resistor, it is necessary to make a protective layer from a piece of mica or ceramics between the rear wall and tip.
7. last thing you want to do - connect to the home-made power supply unit 1 A and voltage up to 15 volts.

That's the technology of creating a homemade mini soldering iron at home.As you can see, nothing complicated, and all the materials can be found at home, dismantling the old equipment.Such a tool can be used for watering smd components on the chips by hand.

idea №3 - A powerful impulse model

And the last option is ideal for those who are already more or less familiar with the radio technology andable to read the relevant scheme.Master-class on making homemade soldering gun will be provided following the example of the scheme:

advantage of a powerful tool that heating of the tip will occur within 5 seconds after turning on the power, and the hot rod can be easily melted tin.At the same time make it possible from the switching power supply of fluorescent lamps, a little improved the cost at home.

• ferrite ring of a pulse converter.The transformer primary winding 100 must consist of a maximum of 120 turns of copper wire and a 0.5 mm diameter.Secondary winding is represented by a single turn of copper bus, a maximum diameter of 3.5 mm.
• Copper wire with a diameter of 1.5 to 2 mm in a sting.

All that you need - to connect to the sting of the secondary coil, which is, in fact, and so is a part of it.After that one of the conclusions of ballast must be connected to a power transformer and all, consider that you have got to make a good soldering gun rapid heating at home!

addition we recommend to view a video that shows how to easily make at home stand for the soldering iron, as well as temperature control:

not want to waste time and createelectrical appliance?Roman Ursu will tell you how to make a simple but effective soldering of lighters without helix and mica:

We still recommend to use either the first or second option, which is more clear and simpleto manufacture.Regarding the transformer embodiment, although it is more powerful, but not so convenient to use.We hope that these photo instructions were helpful for you and finally recommend necessarily see all the video examples in which the assembly process is described in more detail!
