How to Solder Without Soldering Iron (Step By Step Guide)

In this article, we will learn how to solder without soldering iron. Soldering is an essential skill. Soldering iron is a widespread tool to solder two metal joints with the help of solder. If you work with electronics, you will become aware of soldering iron’s importance.

However, soldering iron is a must-have tool used in soldering electronics. Sometimes you might not have a soldering iron on hand, or you don’t want to invest in buying a new soldering iron Tool to make some simple electronic repairs.

In another scenario, consider the situation when you have the soldering iron but do not access the electricity. So my query is How to Solder Without Soldering Iron? I know that it is more challenging to do soldering without a soldering iron, but it is not impossible.

There are plenty of tricks and tools along with almost every type of heat source you can do soldering jobs. So let us talk about How to Solder Without Soldering Iron in this article.

Obligatory Safety Warning

The process of soldering without solder Iron involves closely working with an open flame to complete your soldering tasks. Such type is a more ancient approach to soldering. So I suggest that it is needs to more carefully doing such tasks with open flame.

It is a good idea to keep the fire contained and not try to make it too large. Suppose it was done by the younger ones disabled by responsible adults nearby this place. I suggest you do not wear loose clothes and avoid long hair. You can tie your long hair with a rubber band if necessary.

Getting a Heat Source

As you do not have a soldering iron, you need an appropriate heat source to heat various metals and solder itself. It is a simple activity because you have a lot of heat sources to consider. In this case, we are going to consider the open flame.

Remember that the heating source needs the solder to its melting point. Otherwise, this process will not work. In a typical scenario, the heating point must provide a temperature between 200 to 370 degrees celsius.

How to Solder Without Soldering Iron

1. Solder by Heating the wires directly

How to Solder Without Soldering Iron

This is the simplest type of soldering without soldering iron. This type of soldering process to connecting wires by heating them directly. It does not require any soldering tool.

Now, take two wires and twists their ends together with a few rotations. Ensure that both wires stripe together to remove their insulation parts and twist tightly. After that, I will heat the ends of the wires for about 20 seconds and apply the solder opposite to the exposed wires. We were careful not to want to try to apply solder to the directly heated area because it would create chemical residue.

Now, The solder should melt and makes a thinner layer slowly. You can use a candle or a lighter as a heat source. If it does not melt, you can increase the heat until it happens. Be patient because the wires are too hot. Also, ensure to heat up sufficiently to more than its melting points. I do not want a cold solder joint because it is a defect.

Once you have good metallic solder joints, scrutinize them and cut off the unsoldered section of exposed solder wire. It is a good idea to insulate the soldered joint with the help of any heatsink tubing or electrical tape.

2. Find some scrap metal to use as a soldering Iron

3. Create a Soldering Iron to use with a small heat source such as a candle or a Lighter

4. Create a soldering Iron to use with a significant heat source, such as an open Fire
