How to Make a Heating Element For a Soldering Iron

Heating Element For a Soldering Iron

Suppose you are using a soldering iron to join two components electrically. In that case, you will know that the heating element is the essential part of the soldering iron, which should be present in good quality to conduct its work correctly.

For this, we will briefly explain how you can make the best heating element for your soldering wire which will help the tool work efficiently.

What is the role of a heating element?heating element and soldering iron

Before getting into the procedure, we should know why the heating element is necessary for a soldering iron and the role of the heating elements in the soldering iron.

The heating element is an important part of the soldering iron, which is made of ribbon, coil or wire. There are 2 parts to a soldering iron.

  • Insulated handle
  • Heating region

Now the heating region has a heating tip that contains a Heater and a Soldering Tip. The heating element is present in this region. So it is clear that all soldering iron functions depend upon the heating element.

Heat is produced when current passes from a resistive material. That heat melts the soldering wire, which helps two components join electrically.

How to make a heating element for a soldering iron?

Making a heating element for a soldering wire requires some important steps. Here we are giving you a general overview of those steps.

  • Manage the appropriate amount of voltage needed.
  • Design a perfect Nickel-Chromium wire according to your choice.
  • Cut the Heating coil from one end.
  • Connect the designed Nickel -Chromium wire with a heating source.
  • Check the Heating source.
  • Fix the Heating Coil.
  • Test your heating element.

Now make the heating element by following the steps given below.

  • Manage the appropriate amount of Voltage needed

When you are going to make a heating element by using a Nickel chromium alloy, then you should know what amount of voltage should be needed by your soldering wire to generate heat.

So for this, first, you have to establish a proper required voltage for your soldering wire so that it can produce the required enough amount of heat.

  • Design a perfect nickel-chromium wire according to yournickel chromium wire choice

Look at the soldering iron space and then give an appropriate shape to your nickel-chromium wire. So start coiling the wire to give it the desired shape.

Keep a measuring gadget with you so that you can measure the diameter of the coil at any time while shaping it.

  • Cut the heating coil from one end

If you want to connect the wires, you first have to cut them but ensure you are cutting the end appropriately because sometimes you need to cut the right side of the wire and then it only remains somewhat usable. So cut the end of the heating coil by taking all the measurements first.

  • Connect the designed Nickel chromium wire with a heating source

In this step, you must join the nickel-chromium wire’s heating ends with a heating source. Use insulation and electrical tapes to join the ends correctly and cover the unjoined ends.

A proper connection is required here; otherwise, the screws will get loose, and your heating element will not be able to do its work correctly.

  • Check the heating source

This is the most important step, telling you if you have installed your heating element perfectly or not. So, you have to connect your soldering iron to a voltage supply.

If wires are not conducting heat, you immediately have to change the power supply connections for your soldering iron.

  • Fix the heating coil

If you are sure that all your power supplies are doing well, then it’s time to fix your heating coil by tightening the screws properly at their place so that it doesn’t move from their position.

  • Test your heating element

Set the soldering iron at maximum temperature and leave it for several minutes. If your soldering iron responds to you perfectly, your heating element is working properly.

If it shows any problems, it means your heating element is not in good condition, so if it goes on smoothly during the test, congratulations, you have made it perfect.


If your soldering iron needs to be fixed better, then you should check out its heating element, as the heating element greatly influences it.

To prepare a perfect heating element, you can follow the above procedure, which will help you make the best heating element for your soldering iron so that it can join two components correctly.
