How To Make A Soldering Iron
Place the graphite taken from a sharpened broken pencil graphite in the alligator clip on the green cable.
How to make a soldering iron. This video shows how to make a simple soldering iron using easily available materials. The soldering iron is then dipped in flux and then solder is applied on the tip. Pick up the pencil that has now become a soldering iron.
Copper wire for the tip of the soldering iron. Unfortunately there is no set formula for how to make soldering iron without nichrome wire though there are many different ways one can go about it. Soak the sponge using the water squeeze it out a little then use it to clean the tip of the soldering iron.
Normally for soldering iron 2 ampere to 4 ampere current is enough for this. Wrought iron repair can be done using a soldering iron and solder. To make the heater resistor attach one end of the wire near the sharp end and wind it over the insulation.
Get a piece of iron like an old raid road spike. A 12V 20A DC adapter is used as power source here. A small sheet of copper foil.
But if you sold Brass then you need 12v 10 ampere. Grind off the flat head. Before soldering starts the bit is heated slightly and then filed to remove the layer of oxide.
Heat a small amount of solder on the soldering iron tip and apply the solder to the seam running between the metal pieces as it starts to melt. Place the twisted ends of the two copper wires against a piece of solder to see the solder melt. The simplest power control circuit for a soldering iron is shown in Figure 1.
