soldering iron is a hand tool used in soldering. Provides heat to melt the solder so that it can flow into the joint between two work pieces. This tool consists of a heated metal tip and an insulated handle. Heating is often accomplished electrically, by passing an electrical current, supplied through an electrical cable or battery cables, through a resistive heating element.

Cordless irons can be heated by burning gas stored in a small tank, often using a catalytic heater instead of a flame. Simple irons less used today than in the past were simply a large copper drill bit in a handle, heated by a flame.

Soldering iron is most often used for installation, repair, and limited production work in electronic assembly. High-volume production lines use other welding methods. Large plates can be used to weld together sheet metal objects. Less common uses for soldering iron include pyrography, burning wood designs, and plastic welding.

Soldering is a useful skill, whether you plan to use it professionally or for DIY projects. A quality soldering iron is one of the most important tools you will need for your lab projects. Although all soldering irons are based on the same principles, the techniques and tools you use may vary depending on the type of materials you are welding and the type of result you are seeking.

Next, we will talk about one of the best known laboratory tools, along with the beaker . Join us!

What is a soldering iron?

A soldering iron supplies the heat that melts the solder . It consists of a tip, which you apply to the metal parts you want to solder, and an insulated handle so that you can hold the iron. There are several variations of soldering iron. They are often electric and use an electrical cord or battery. Some also use the combustion of a gas such as butane or an open flame. Some irons allow you to adjust the temperature of the iron.

Most electronic soldering irons have interchangeable tips, also known as bits, that vary in size and shape for different types of work.

Pyramid tips with a triangular flat face and chisel tips with a wide flat face are useful for welding sheet metal. Tapered or fine tapered chisel tips are generally used for electronic work. These can be straight or have a curve. Concave or absorbent tips are available with a chisel face with a concave cavity on the flat face to hold a small amount of solder.

How to use the soldering iron

First, determine the right temperature for your soldering iron project. The temperature to use depends on the materials you are joining and the type of solder you are using. As a general rule of thumb, the best temperature to use is the one that is as low as possible and at the same time high enough to get the job done.

In other words, if the temperature needed to do the job is 370 degrees or higher, set the soldering iron temperature to exactly 370. This will help extend the life of your tools and prevent damage to electronic components.

Once your iron has heated up to the proper temperature, grasp the iron by the handle with one hand and hold a piece of solder in the other hand. Keep the hot iron in the place where the two metal components will meet for about a second to heat them up. You want to heat the metal parts, not the solder itself.

Check the quality of the soldering iron joint. A good connection will appear smooth, uniform and shiny. Make sure there are no problem gaps between components or excess solder balloons.

Soldering iron types

Simple iron soldering iron

For electrical and electronic work , a low-power iron is used, a power rating between 15 and 35 watts. Higher ratings are available, but they do not run at higher temperatures. Instead, more heat is available to make soldered connections to things with high thermal capacity, for example a metal chassis.

Some soldering irons have temperature control, they work at a fixed temperature in the same way as a soldering station, with more power available for joints with high thermal capacity. Simple plates operate at an uncontrolled temperature determined by thermal equilibrium.

Cordless Iron Soldering Iron

Small irons heated by a battery, or by the combustion of a gas such as butane in a small, self-contained tank, can be used when electricity is not available or wireless operation is required. The operating temperature of these irons is not directly regulated. The gas soldering iron can change the power by adjusting the gas flow. Gas powered irons can have interchangeable tips including different size solder tips, hot blade for cutting plastics, miniature torch with a hot flame, and small hot air blower for applications such as heat shrink tubing.

Soldering iron with temperature control

The simple soldering iron reaches a temperature determined by the thermal equilibrium, which depends on the energy input and the cooling of the environment and the materials with which it comes into contact. The temperature of the iron will decrease when it comes into contact with a large mass of metal, such as a chassis; a small iron will lose too much temperature to solder a large connection.

The most advanced soldering iron for use in electronics has a mechanism with a temperature sensor and a temperature control method to keep the tip temperature stable. More power is available if the connection is large.

Temperature controlled plates can be stand-alone or can comprise a head with heating element and tip, controlled by a base called a soldering station, with temperature control and adjustment circuits and sometimes a display.

variety of means are used to control the temperature. The simplest of these is a variable wattage control, much like a light dimmer, that changes the equilibrium temperature of the iron without automatically measuring or regulating the temperature.

Station soldering iron

A station is temperature controlled and consists of an electrical power source, a control circuit with provision for temperature adjustment and user display, and a soldering iron or welding head with a tip temperature sensor. The station will normally have a hot iron holder when not in use, and a damp sponge for cleaning.

It is most commonly used for soldering electronic components. Other functions can be combined; for example, a station, primarily for surface mount components, may have a hot air gun, a vacuum tool, and a welding head.

Soldering iron with tweezers

Soldering clamps can be used to solder and desolder small surface mount components with two terminals, such as some links, resistors, capacitors and diodes. They can be independent or controlled from a soldering station . The tweezers have two heated tips mounted on arms whose spacing can be varied manually by gently squeezing against the spring force, like simple tweezers.

Soldering iron stands

soldering iron holder keeps the iron away from flammable materials and often also comes with a cellulose sponge and a flux pot to clean the tip. Some soldering irons for continuous and professional use come as part of a soldering station, which allows you to adjust, hold constant, and sometimes display the exact temperature of the tip.

Soldering iron cleaning

When the iron tip rusts and burnt flux builds up on it, the solder no longer moistens the tip, preventing heat transfer and making soldering difficult or impossible; tips should be cleaned periodically in use. Such problems occur with all types of soldering irons , but are much more serious with lead-free solders that have become widespread in electronic work, which require higher temperatures than lead-containing solders.

Exposed iron plating rusts and if the tip is kept tinned with molten solder, rust is inhibited. A clean, non-oxidized tip is tinned by applying a little solder and flux.

A small damp sponge, often supplied with soldering equipment, can be used to clean the tip. For lead-free soldering, a slightly more aggressive cleaning can be used, with brass shavings. The solder flux will help remove the rust; the more active the flux, the better the cleaning, although acid flux used on circuit boards that is not cleaned carefully will cause corrosion. A tip that is cleaned but not retained is susceptible to oxidation.

The tips of the soldering iron are made of an iron-plated copper core. Copper is used for heat transfer and iron cladding is used for durability. Copper corrodes very easily, gnawing away at the tip, particularly in lead-free work.

Iron is not. Cleaning tips require the removal of rust without damaging the iron coating and exposing the copper to rapid corrosion. Using solder that already contains a small amount of copper can delay the corrosion of the copper tips.
