What Is a Soldering Machine Used For?A Full Guide To Know How Does It Work!


A soldering machine is any piece of equipment used for the purpose of soldering, in which a metal alloy - traditionally made from tin and lead - becomes a filler material that is primarily used to create a soldered joint between two components. The most common purposes of this are to build a smooth connection between two different pieces of metal or to support the continuation of electrical conductivity. 


The solder materials market is expected to hit $2,225 million by 2030 while soldering machines are used by a growing number of professional and recreational users. If you are about to step into the world of soldering, this guide will answer your key questions, such as;

  • How does soldering work?

  • What are the most common applications of soldering?

  • Why is soldering important?

  • What are the auxiliary materials of soldering?

  • What are the different types of soldering?

  • Which soldering machines are available?



How does soldering and a soldering machine work?


A soldering machine is a piece of equipment that heats the solder alloy material into a liquid state (at around 600 degrees Fahrenheit) and then applies the melted materials to fill the space between the two target components. The liquid is then allowed to cool and bond, creating a permanent join - although solder material can be removed if reheated back to a liquid state.


While lead was traditionally used for soldering, changing regulations mean that non-lead alternatives are now commonly utilized. They include antimony, bismuth, brass, copper, indium, tin and silver.


The definition of a soldering machine could cover anything from a simple soldering pencil or handheld soldering gun to an industrial soldering machine. The best machinery will include workstations and allow you to benefit from automatic dip solders and angle turns, allowing you to focus only on putting the coil to the fixture and subsequently unloading the finished piece by hand.


Soldering processes also need to use a flux, which removes the oxide films that naturally form on metal surfaces during the soldering process. In turn, the flux increases the wetting ability of the solder metals, which promotes a smoother application. A type R rosin flux is the most basic version although no-clean, water soluble, IPC J standard flux materials are also used in some soldering machine applications.

The common types of soldering

When asking “what is soldering?”, it’s not only important to appreciate the fundamental principles of heating the tip of the iron so that the alloy solder material can be applied. Soldering is commonly split into three main types, they are;


Soft soldering occurs at between 90 °C and 450 °C and causes the least thermal stress on components but also creates the weakest joins of the three types, which does limit its application to items where load-bearing strength is not needed. 


Soft soldering will see the metals that are being bonded heated to a melting point.


Hard soldering is when the solder material is heated to a temperature of more than 450 °C. Brass and silver are the most commonly used solder materials in hard soldering while a blowtorch is required to help them reach the desired temperature.


However, unlike soft soldering, the target materials do not melt - hence the name.


Brazing also occurs at temperatures exceeding 450 °C, although often significantly hotter than hard soldering. The metals that are being bonded will be heated, much like hard soldering, and the soldering metal is melted to become the bonding agent.

The temperatures are the main difference between the metal joining processes.

What is soldering used for?

Soldering machines are an important tool that may be used in a wide range of industries, including automotive repairs, manufacturing,electronics. Essentially, any sector where joining metals together through a melted solder material could be beneficial is likely to utilize a soldering machine.  

While soldering may be used for a range of applications, the most common are;


  • Soldering for electronics. When working with plastic circuit boards, soldering enables the electrical current to pass from one wire to the next. Solder is, therefore, used in a plethora of electronics.

  • Soldering for auto repair. Mechanics may use solder to fill holes, fuse metal panels, ti metal sheet edges and complete body repairs. Soldering may also be used to tighten joints.


The examples above showcase the versatility of soldering, but it should be noted that there are huge contrasts between different applications. For example, the soldering of electronic components requires precision to avoid damage to the circuit boards and wires. So, in this case, soldering technicians will use borax flux to reduce oxidation when applying heat to metal. Conversely, a roofer may use broader soldering tips because the need for accuracy is far smaller. 

Explaining different soldering machine types

Soldering machines are an important tool that may be used in a wide range of industries, including automotive repairs, manufacturing,electronics. Essentially, any sector where joining metals together through a melted solder material could be beneficial is likely to utilize a soldering machine.  

When looking at different types of soldering machine, you need to appreciate the different types of soldering tools. A soldering iron is a relatively light hand tool that features an insulated handle and a heated pointed metal iron tip. Alternatively, a soldering gun has a loop shaped tip that can deliver increased power and flexibility. 


Alternatively, you could use a soldering station like the Teeming 10 station soldering machine, which gives you far greater flexibility and a more professional set-up. Dedicated soldering machine stations allow you to:

  • Dial a variety of temperatures rather than the set temperature as is the case with standard soldering irons.

  • Precise control of rosin concentration

  • Utilize different jig setups, using different soldering tips to suit the specific job that you need to complete.

  • By different jig to make precision soldering

  • Control the volume of your dip flux with far greater accuracy to achieve the best soldering results for each job.

You can also automatically set soldering times,blowing time or bending, giving you a truly comprehensive and professional approach to soldering production.

Understanding different soldering machine tips

In addition to the different soldering machines, it’s important to understand the various tips that may be used. Also known as soldering bits, they can have a telling impact on the results of your soldering activities, which is why selecting the right type is vital.

Here are the most common types, and their primary functions;

  • Bevel tips. Also known as hoof tips, they are cut off at an angle. This allows for accurate drag soldering and small wire soldering because the available surface is larger than the tip itself.

  • Chisel tips. They feature a flattened tip that is also quite broad, making it possible to create an even distribution of the solder material across large surface areas. It can also be used for desoldering.

  • Conical tips. Primarily used for precision soldering, conical tips are characterized by their pointed shape that resembles a pencil tip. They are very common but you must avoid using too much pressure.

  • Knife tips. Designed for reaching slotted cavities or fixing broken solders, they are identifiable by having a sharper edge down one side. They are another good option for desoldering.

  • Blade tips. They are broader and wider than the other options, making them great for saving time when completing rework or pad cleaning duties due to the thinner spreading surface.



Soldering is a valuable process that’s needed for a wide range of metalwork applications. While different jobs require varying equipment and soldering styles, the fundamentals of using a filler alloy metal to create a join between two target metals remain the same. With the right soldering machine and a little experience, it provides the quickest and most effective solution.
