Intro: How to Solder Without Electricity (or a Soldering Iron)Soldering is a valuable skill. There are a lot of situations where the ability to repair or modify electronics can really save the day. But most people don't carry a solderingiron around with them. And even if you did have a soldering iron, there is a good chance that you might not have access to electricity.

So today I am going to show you how to solder using random objects that you might find lying around (and a little bit of solder).

Step 1: Watch the VideoHere is a video walkthrough of this project.

Step 2: Obligatory Safety WarningThis project involves working closely with open flame. So be sure to take all the necessary safety precautions. Always closely monitor a fire and never leave itunattended. Keep a responsible adult nearby with a fire extinguishing tool. Make every effort to keep the fire contained and away from other flammable objects. Avoidloose clothing and hair. Be careful to avoid burning yourself, especially when handling objects that are on fire or have been heated by the fire. When possible wear fireresistant gloves.

Seriously, I am not responsible if you set your house on fire.

Step 3: Find a Heat SourceThe first thing that you need is an appropriate heat source. You have a lot of options for this. You can use anything that is able to heat a piece of metal up to the meltingpoint of your solder (between 400F / 200C and 700F / 370C). Butane lighters work the best. But you can also use candles, oil lamps, alcohol burners, or even opencamp fires.

Here is a list of tutorials that show how to make some simple fires.

Step 4: Solder By Heating the Wires DirectlyThe simplest kind of soldering is just connecting two wires together. This can be done by heating the wires directly and doesn't require any kind of a soldering iron.Take two wires and strip the insulation off of the ends. You want there to be about one inch of exposed metal on each wire. Then twist the wires tightly together.

In order to solder the wires together, we will be heating the ends of the wires and applying solder to the opposite side of the exposed section (where the wires first meet).You do not want to try to apply solder to the heated area because soot and other chemical residues can build up on this area and make it difficult for the solder to stickproperly.

So take your heat source (preferably a candle or a lighter) and use it to heat the ends of the wires. Wait about 20 seconds for the wires to heat up. Then slowly applysolder to the other side of the exposed section of wire. If the solder does not readily melt, let the wires heat some more. Be patient. You need the wires to be hot enoughto properly wick the solder. Otherwise you may get a cold solder joint.Once you have a good solder connection, cut off the unsoldered section of exposed wires. This will leave you with just the soldered connection. Whenever possible it is agood idea to insulate any connections with either heat shrink tubing or tape.

Step 5: Find Some Scrap Metal to Use as a Soldering IronWhen soldering on a circuit board, you can't heat the board directly with an open flame. So you need to use something as a soldering iron. You can probably find asuitable piece of metal laying around.

Steel is a good material to use for this. It is strong. It retains heat fairly well. It is also very common. So you can find pretty easily in most places. Copper can work butcopper cools off much more quickly than steel. So if you use copper you will need to work quickly.

Here are some examples of object that can work:steel wire (at least 14 gauge)nails

screw driver

bolts

multi-tool

rebar

The thicker an object is, the more heat it will take to get it to the appropriate temperature. So for small heat sources such as candles and lighters, use thinner solderingirons. For larger heat sources, you can use larger soldering irons.

Step 6: Create a Soldering Iron to Use with Small Heat Sources Such as Candles and LightersWhen working with small heat sources such lighters and candles, you need to use a small soldering iron. The ideal material to use for this is 14 gauge steel wire. This issmall enough that it heats up quickly but larger enough that it can retain the heat long enough to soldering with. It is also easy to bend the wire into any shape that isconvenient for you to work with. But if you can't find steel wire, you can also use nails and screw drivers of the appropriate size.

I bent the end of the wire over. This effectively doubled the thickness of the soldering tip. Then I bent the end of the wire at a 90 degree angle. This "L" shape made iteasier to get a flame under it.

In most cases you will probably hold the soldering tool separate from the heat source. However in the case of a stick lighter, it is relatively easy to attach the wire to theend of the lighter. All you have to do is wrap the wire around metal neck of the lighter and position the soldering tip over the flame.

When using the soldering tool, you want to heat the section of metal that is about 1/2" from the end. This leaves the tip of the tool clean and free from oxidation orchemical residues.

Allow the metal to heat up for 10 to 20 seconds. Then quickly move it to the components that you want to solder. You will usually just have enough time to solder a singleconnection. Then put the tool back over the flame and let it heat up again.

Step 7: Create a Soldering Iron to Use with Large Heat Sources Such as Open FiresIf you are working with a larger heat source such as a fire place or a camp fire, then you need to do a few things differently. First of all, you will need to take many moresafety precautions. Wear fire resistant gloves and whenever possible, use metal tongs or pliers when handling the heated soldering tool.

A wood fire is much hotter than a candle or a lighter. So you will want to use a tool that lets you work at a safe distance. To do this you can either use a long wire or youcan attach your soldering tool to the end of a non-combustible rod such as a piece of steel rebar.

An open fire provides a lot more heat than a lighter but it is much more difficult to precisely control. So you will probably want your soldering tool to be made of thickermetal. This will help it to catch and retain more heat. If you are using a wire as your soldering tool, you can make the tip thicker by folding the end of the wire over severaltimes.

How and where you heat the solder tool will depend on the kind of fire that you are working with. Hot coals will generally be a more steady heat source than leapingflames, but you will need a lot of glowing coals to heat your soldering tool. You will probably have to use some trial and error until you get a feel for what works. To makeit easier, start with a larger fire. This will give you a larger and longer lasting coal bed to work with.

After you have heated your tool, move it quickly to the object that you want to solder. Be careful! Once the soldering tool is no longer able to melt the solder, move it backto the fire to reheat it.
