How to make a soldering iron do it yourself

Soldering iron - for many empty sound, but for most men is an indispensable tool in everyday life. And even no matter whether you are working in the repair of electronics, or simply an inquisitive mind of the hands of peace does not give. In this article, we will talk about creating a soldering iron with your own hands from the primary materials. But immediately make a reservation, which is easier to buy, it will be more reliable and safer for your health.

1) How to make a soldering iron with your own hands - the concept of the soldering iron

As you can see, the soldering iron is very simple in terms of construction and everything you need for its self-assembly at home, it is quite in every home.

How to make a soldering iron with your own hands - what will be needed

Our acting soldering iron model will work from the battery by 12-14 volts. It is much safer than to use 220 volts in a homemade soldering iron.

• Li-ion rechargeable battery (it is quite suitable from the power tools or an old laptop).
• The segment of a single-core copper wire with a diameter of about two millimeters and five to five centimeters long. She will need to winding the spirals.
• Heat-resistant fiberglass tubes with different diameters of 3.8 and 1 millimeter for insulation of the heating element from metal casing (can be taken from the electric kettle).
• The nichrome wire of diameters is 0.3 millimeters (you can take from the old hair dryer). We will sweep the length of the wires by experimentally depending on the power of the soldering iron and the battery.
• The segment of the telescopic antenna from the radio with a diameter of 4 millimeters and a long 3 centimeter.
• Segment of copper single-core wire for sting, with a diameter of 3.8 millimeters.
• Wire for power supply to the soldier.
• Wooden or plastic handle tube.

How to make a soldering iron with your own hands - assembly

• For the beginning, we will make the manufacture of the heating element.
  We wrap a nichrome thread with a segment of the wire and by selecting the length of the spirals, we will achieve heating in the tales of 300 - 450 degrees Celsius.

• Take all the same segment of a single-core copper wire and put a heat-resistant tube on it.
  The cut of the spiral segment we wore the tube.

• On the tips of the spiral we wear thinner tubes and put the entire design inside another, thicker tube. Let's look out the copper wire (he fulfilled his role and we don't need more).

• All, heating element is ready. Now it remains to insert inside the copper tube from the antenna and put our sting in it. Powers fix in the tube with a self-tapping screw.

• Our soldering iron is almost ready. It remains to attach a spiral-feed wire to the ends, insert the entire design into the handle and connect to the power source.

Important: Between the handle and the antenna tube you need to place any non-combustible material to avoid the emergence of the fire. ZMP for this purpose is quite suitable.

Let's summarize all the above. To create a soldering iron, you will not need any special knowledge and expensive components. But such homemakes should be done only in the case when you need to solder something, and the soldering iron is simply not at hand. And elementary there is no time for shopping in order to acquire it. In all other cases it is easier to buy it, especially since he is not great money. But in terms of security, the factory is much more reliable of all kinds of homemade.
