How To Make A Soldering Iron With 9v Battery

Less than a second.

How to make a soldering iron with 9v battery. Tin both both sides of the batteries with a small amount of solder let it cool down before soldering the wires to it. It will heat as long as you keep it in contact with the wire. It is very useful tool.

In this video Im going to show you how to make a simple soldering iron. When the solder starts to melt apply a fair ammount then remove the wires from the soldering iron allow it to cool and youa re good to go. So I made my own Das Neunvoltzensvitcher.

There are at the moment some 9v rechargeable batteries but the capacity is low and the price is quite highso in addition we will make a simple exercise of how to wire some 18650 cells in series to form a 9v battery pack rechargeable with the capacity of 2500mAOne other method is to use rechargeable aa batteries but we have to use morebecause the voltage of a rechargeable AA is around 12v. Current batteries are made of alloys on which soldering is very poorly held. Id like to know if soldering two wires directly on a NiMh battery is considered as safe or not.

A good solder joint will be smooth and shiny. When the surfaces are hot enough the solder will melt and flow into the joint. Hello Guys its time for another amazing video.

Cut the wires from your battery adapter to a shorter length feed the wires from the input of your buck converter through their hole in the enclosure and solder them to the battery wires. Place the wire next to it reheat the solder and slide the wire into the melted solder. This is done with a special brush.

I would suggest holding the iron on one side and the solder on the other side. Using the same process do the same on the other side of the battery holder. The longer you leave your iron on the battery the more heat will build.
