The first step to repairing your soldering iron is establishing whether the heating element is indeed spoilt. Below are the steps to determine the problem: Connect your soldering iron correctly to the receptacle to observe the readings. The heating element connects to pins 1 and 2 of your soldering iron receptacle.

What is the best temperature for soldering iron?
Here’s a look at what you can expect from irons with different wattage rates:
- The cheapest soldering irons are typically rated between 10 and 35 watts and have a fixed output. ...
- The next step up is a powerful-yet-basic soldering iron of up to 60 watts. ...
- Some entry-level soldering stations of 5 to 60 watts offer variable power with two or more presets. ...
What is the function of soldering iron?
Soldering irons are simple devices, with the primary function being to heat solder enough to melt it and move it to the needed place using the sharp tip. Most soldering irons consist of an electrically (and in some cases, direct heat from a flame) driven heating element which supplies continuous heat to a sharp tip, where solder is melted.
How to build a simple soldering iron?
Things You Would Need
- You can use the glue gun on the side of the wooden piece so that it would be possible for you attach the syringe needles to it.
- Next, you have to connect one end of the wires to the needles while the other to a battery (step 4).
- With the help of a plier you can bend the needles so that when you work, it would be easy for you. ...

Can you solder a heating element?
Heating elements should never be soldered, as solder melts at around 180 to 190 degrees C, depending on the alloy; this is much too low for heating elements. The manufacturer probably spot welded or crimped the connection (or both).

Can you use steel wool to clean a soldering iron?
Take a steel wool pad and dampen it slightly, then scrub it over the iron's tip to remove rust and any other heavy staining. Steel wool is the only cleaning item safe to remove rust or stains with. Avoid sandpaper, which is too corrosive for solder iron tips.
Can you use alcohol to clean soldering iron?
So using a piece of cotton or tissue with an isopropyl alcohol to clean your PCB before using is a good idea. Clean the soldering iron tip by getting it to temperature and cleaning it with a damp wipe.
Can soldering iron be fixed?
It is very easy to repair a Soldering Iron. A soldering Iron has a Heating Element and a Control Circuit for Adjusting the Temperature.
What do you do if solder won't melt?
Solder has a very low melting point (compared to other metals/alloys). Even a weak 40W iron should melt it almost instantly. If it's not melting the solder, then the iron is not hot enough or even working. Try poking the tip through a piece of paper.
Why is my solder not flowing?
Heat is the number one reason that solder flows. Without it, you'll unsuccessfully try to solder a piece for a very long time. Heat is a tricky thing to figure out, especially if you're just starting out.
Why is my solder turning black?
When oxidation occurs, the tip becomes covered with a black or brown scale, which will not wet with solder – greatly reducing heat transfer. This is commonly known as “burn-out”. Burned out tips are usually discarded, though they may often be cleaned carefully with a fine abrasive and retinned.
Do soldering irons go bad?
Soldering Iron tips do not last forever. Eventually they wear out. Common signs that the tip needs replacing are: a hollow forming in the end of the tip, cleaning and re-tinning has no effect, or needs frequent repeating.

How Do You Make A Heating Element For Your Soldering Iron?
They’re essential for many appliances, including furnaces, dryers as well as coffee makers. Here’s an outline of the steps to follow when making a heating element for your soldering iron.
Where is the heating element located on a soldering iron?
One of the most vital parts of the soldering iron is the heating element. This component is located at the tip of your soldering iron and comes with heat insulation. It’s usually either powered with a battery or the mains electricity.
What to do if your heating element doesn't heat up?
If these wires don’t heat up, you need to disconnect the soldering iron and change all the power source connections.
How does a heating element work?
The heating element usually functions through resistive material, which entails electrical current passing through it. This process is similar to that of the electric bar fire, albeit not being as hot or aggressive.
How to position a heating coil?
After confirming every connection is working correctly, proceed to position the heating coil by fastening the surrounding screws. Subsequently, follow this up by installing it into the space allotted inside the soldering iron and get new covers if necessary.
What is a heating element?
Heating elements are generally made from a strip of wire, ribbon, or coil that offers heat, such as a lamp filament. Most of these heating elements comprise an electric current that flows through the wire, ribbon, or coil, thereby making it very hot. Consequently, this electrical energy is converted into heat that’s spread in all the directions.
Why use a soldering iron?
You should ideally opt for a lead-free solder to prevent exposure to any harmful materials.
