Here are common ways of making a soldering iron via DIY means:

DIY Methods of Making a Soldering Iron

An iron affiliated solder is a necessity when doing soldering works on a project. Making a soldering iron is super easy and most importantly, all needed accessories are easy to reach.

Although making one will differ from purchasing a professionally manufactured one, it will do great work. Why not try one? Saving costs is one of the best thing to do and making your soldering iron is the best deal of the year.

Here are 3 recognized and proven DIY methods of making a soldering iron:

Method 1: Making a Soldering Iron Using 6 V and 12 V Battery

Step 1

Start by placing a clean paper sheet on a stable table. Proceed to place a marker on the already laid paper sheet. When placing, ensure it’s horizontally set-up. Use a sharp blade to cut a slightly on the marker.

Step 2

Remove the marker lead by using your fingers or a suitable tool. Ensure that you discard the already cut-off parts on a trash bin.

Step 3

Start by cutting off the endpoints of the marker using a sharp blade and discard it on a convenient trash bin. Always discard away unwanted substances to make the working setup clean.

Step 4

Since you are using a battery, install the multiple “A” batteries on the paper sheet. Importantly, the positive side should face differently from where you are situated. Link the batteries intact by using the right electrical tape. 

Ensure that everything runs well and conventionally across the center location.

Step 5

Use a pair of scissors or any other great cutting tool to cut multiple 14-inch iron wire. Proceed to twist both ends of the iron wire to make a one unit.

Link the multiple ends of the iron wire on the marker (pencil) and ensure one twisted is placed on the marker’s right side.

Step 6

Pull one of the multiple iron wires starting on the left side of the marker. Run it through the negative sides of the battery. Ensure that you anchor the iron wire with electrical tape.

Repeat this procedure with the other wire contacting the positive battery link.

Step 7

Link the two batteries on the left side of the marker. Use electrical tape to link them.

Step 8

Take the marker pencil and by now it’s already soldered into iron. Insert both twisted ends against a solder. Check if the solder is melting or not.

Step 9

Uninstall the positive link of the batteries. Proceed to uninstall the iron wire from the link points. Finishing this process will give you a DIY soldering iron. A simple DIY method that is easy to accomplish solely.

Method 2: Making a Soldering Iron Using a Pencil

Step 1

Having all required tools close makes it easy to making a soldering iron. Required tools will be outlined in later pages of this review post. Some commonly used tools include:

  • An electrical tape
  • Two extensive iron wires
  • A pencil
  • A 12 V and 6 V battery
  • An iron tube (hollow by design)
  • A sketch marker pen

Step 2

Make iron ends joints by denting them attached. Attach the end of iron to ensure that its installed properly.

Step 3

Link the iron wire and proceed to cover it using a piece of a paper sheet. Using a quality paper ensures that the tape doesn’t burn in case the iron rod becomes hot.

When soldering, extreme heat is prevalent and since the paper is a poor heat insulator, you should always have it by your side.

Step 4

Sketch the body and install it on the tool. When doing this procedure, you might need to make cut adjustments to ensure everything is working right.

Method 3: Making a 12 V Soldering Iron

Step 1

First, start by filling an end of the iron copper rod. Make a conical design and use extreme temperature resistant sleeves. Embark to cover almost 1/3 iron wire by revealing its end.

Step 2

Get a cylindrical affiliated wooden accessory and drill 2 cm deep. Also, ensure the wooden accessory is drilled 3 mm. Use a nose affiliated plier to anchor the iron material.

Step 3

Coil the iron wire approximately 35 cm along the sleeve. Tie these ends using a 1 mm copper wire.

Step 4

Link one iron end to the positive battery clip and also tire the solid iron wire on the other end. To secure the wooden handle, utilize a quality glue agent that complements with electrical appliances.

Step 5

Ensure that the negative lead clip is tied well with the other iron wire. Importantly, ensure that the wires are anchored strongly to the lead clip for proper current flow.

Step 6

Link the lead battery clips onto a 12 V acid based battery source and embark to switch the circuit on. After linking, you might notice smoking incidence as the iron enamel burns. Importantly, protect the tip of already made soldering iron using a quality solder iron material.

Your DIY made soldering iron should be ready now and ensure that wires are installed on the positive side of the battery from the solder. By following all above mentioned methods, it’s easy and convenient to make a soldering iron.

All above mentioned methods are great for making soldering irons tool. In case you get an emergency and lack funds to buy a new soldering tool, you can use one of these methods to get one. All that is required is having the right tools and expertise to make a soldering iron tool.

Required Tools

Before making a soldering iron, it’s vital to be armed with the right tools to accomplish this task. Here are the necessary tools used to make a soldering iron.

A Pencil

A pencil is used to insert the iron wires to make a DIY soldering iron. To do so, remove the lead material at the middle of the pen and fit the iron wire.

A Sketch Marker

Cut this accessory halfway.

Two Iron Wires

Seek for long iron wires and ensure that they are made of 0.75 mm thickness. Wires made of this thickness have great potential for maintaining the current passing.

A Paper Sheet

Go for a durable paper sheet and a newspaper is a robust one to utilize. Avoid using magazine affiliated paper sheets.

Electrical Tapes

Use an electrical made tape to protect and at the same link everything together. You can get the best in electrical appliances shop outlets.

A Pair of Scissors

Scissors are used for cutting the end of iron wires. Use strong scissors to make straight wire cuts. In case you use poor pair of scissors they usually make dull cuts lead into brittle of wires.

All these tools will give you an easy process when making own soldering iron tool. Thankfully, these tools are readily available in the market.

FAQs Related to Making DIY Soldering Irons

Let’s look at some common online asked questions concerning making DIY soldering iron. Information revealed in this section will help you get helpful insights concerning making a soldering iron.

Here are common online asked questions about making soldering irons tools:

Q: How can I increase the durability of the soldering tooltip?

Ans: A common issue technicians’ face when soldering’ is the short life of the tooltip. Since tips are subjected to extreme temperatures, it wise to be devised with these important tips for extended durability.

  • When not soldering, always shut off the heat.
  • Clean the tooltip thoroughly to ensure it lasts longer and also is effective when working.
