There is no universal soldering iron, which can be equally high quality and convenient to solder both twists and SMD components. For each task, there is a perfect device. Some of them can be literally made with their own hands.
1. Simple welding machine for twists
For this homemade, you need to remove a graphite rod from the battery. Then it will be necessary to install 2 wires on the battery terminals. The rod is connected to the edge of one of them.
This device can be used to welding twists. The wire from the minus terminal is applied at its beginning, and the electrode presses the edge for several moments. As a result, the twist is welded.
2. Infrared soldering iron from cigarette lighter
Car cigarette lighter can be used to make an infrared soldering iron for SMD components. For this, it breaks out the outer casing. Then one wire is primed to a cup of heating element, and the second to the remaining contact.
Such a soldering iron is connected to the battery or 12V power supply, you can even from PC. The heat-out of the heating element is enough to perform the SMD component soldering.
3. Powered for a pulse soldering iron
A homemade sting from copper wire can be installed in a pulse soldering iron. It differs from the standard availability of turns before the twin tip. Due to the massiveness, such a sting is better keeping the temperature. In addition, it holds more solder.
4. Double sting for SMD components
For simultaneous soldering of the two legs of the SMD components, you can wind on the tip of the soldering iron a thick copper wire. Her edges are bred to the side at the desired distance. We get 2 sting for soldering.
You can also form a frame from wire. This will allow you to heat evenly all the legs of the complex component.
5. Pulse soldering iron do it yourself
Two halves of the soldering iron housing with a pistol handle are peeling from plywood or boards. Then the bracket is beaten from the copper tire. For her you need to cut into the package of the groove.
The bracket is inserted into the housing, and the round ferrite core for the inductor coil is put on it. On the latter wreath 2 mm copper wire 2 mm.
The coil nutrition is summarized by the proposed scheme using the IRF3205 field transistors and 470 ohm resistors, 100 ohms. The contact button is installed on the handle, and the sting on the tires. As a result, we obtain a powerful soldering iron on 12V with instant warming up.
6. Soldering iron for a mezzanium from the field transistor
It is necessary to climb the wire to the third leg of the IRF3205 field transistor. Legs 1 and 2 are twisted by the second wiring.
Between them stacked the isolator and primed. Now when power is applied 12V DC, the transistor will be heated.
Due to its width, it is convenient to browse the fees and various planes.
