If you are looking for a MIG welder or information about them, you are in the right place. In this article, we will try to explain the characteristics and factors to consider in regards to MIG welders, and in the same way, help you find the ideal welding machine for you.

Before you begin, you should know that having a MIG welding machine is advantageous, either for a workshop or for personal use, as long as welding is a fairly recurring activity. And it is that with a MIG welding machine, the thickness of the metals that join increases without sacrificing precision.


The best MIG MAG welding machines of 2021

We have classified the best MIG welders on the market in different categories, according to the voltage, and the mode of operation, and in the same way the performance. The purchase of a higher-performance welder is amortized through faster and more efficient joints with cleaner seams.

But, depending on the use that you are going to give it, it is often enough with welding machines with less voltage, and in this way, less price.

The best MIG Inverter welder of 2021

Green cut- MIG / MAG Inverter Welder / Continuous Thread 185

This is the best MIG Inverter welder taking into account the price/quality factor. It is a very versatile welder since you can weld with MAG (active gas) or MIG (inactive gas) in addition to being a normal electrode welder.

It is a totally safe and stable welder. It can be adjusted from 25A to 185A to achieve perfect and precise finishes in any material type. Also, it has the latest technologies in the world of welding, such as IGBT and PWM technology. In this way, we can achieve professional results.

In short, it is versatile, reliable, and powerful equipment that comes with many elements, although it also has some drawbacks. Among them, it can be noted that the mass electrode is too short to do its job well or that the instruction manual is quite disastrous.

The best 110V MIG welder of 2021

The 110-volt welding machines are perfect for smaller jobs and can be found much more affordable than those with higher voltage.

The fact that the voltage is smaller does not mean that the welding power and quality must be sacrificed. I assure you that these MIG machines provide enough power for the price they have :

It is a 110V welding machine, simple and economical, which will do its job extremely well. It works perfectly, and if what you want is a welding machine for your DIY projects, it is enough for you and highly recommended. Always keep in mind that you are not a professional welder.

The most remarkable thing about this welding machine is that it is easy to use, so it is highly recommended for beginners and not experienced people. Also, this system is much easier than welding with an electrode to start. The only thing you have to learn is to control the speed and the power of the thread a little.

The welder comes with a free reel to start the job better and also brings a mask and a pickaxe, which, although they are not of excellent quality, can serve you for the first fudges until you buy higher-quality protections.

The best cheap MIG welding machine of 2021

Buyer Guide

What is a MIG welder?

It is used to weld metals of thicknesses greater than ¼ inch, using inactive gas to protect the atmosphere. The MIG welder maintains an arc of the consumable electrode of solid wire and the piece to be welded. This machine’s use has been increasing due to companies’ requests, as it allows them to lose minimum quantities of materials, increasing productivity levels.

MIG Welding Machine Uses

It can be used to weld various materials, such as carbon steel, stainless metals, aluminum, etc. Its productivity has a high percentage of efficiency, given the continuous electrode’s performance capacity, which does not need to be changed with a higher relief rate than the others, allowing welding to be carried out long and continuously.

Although several types of welding processes, the process most used by industrial and amateur manufacturers is MIG welding, MIG welding is the most basic welding process. It is still considered the standard in industrial welding processes.

While it is not a particularly difficult process to learn, it requires complex equipment and requires practice to master the different MIG welding positions. But with a good welder and desire to learn, anyone can become a good MIG welder.

MIG welding Process

The MIG welding process involves using a consumable cable fed from a reel to the junction on the metal you want to weld.

This is done using a MIG welding gun fed by an inert gas to produce a high-temperature arc to melt the wire feed into a bead in the joint.

There are three basic and distinct processes. We have the “ short circuit ” transfer, “ globular ” transfer and the “ sprayedarc transfer. Let’s see what they consist of:

  • Short circuit transfer: known as a short arc. The change of metal occurs when an electrical short circuit is determined, that is, when the wire makes a joint with the molten junction at the tip of the wire.
  • Globular transfer: it is a process by which the drops of the metal – call it molten – are too large to sink by the force of gravity.
  • Spray arc transfer: occurs when small drops of molten metal are removed from the wire’s tip and projected into the weld.

If you have questions about the type of welding you need, I recommend looking at our article types. Advantages and differences.

Advantages of using the MIG welding machine

  • They are recommended due to their ease of operation, as they produce high manufacturing rates for their performance.
  • Welding instruments such as cables and guns are lightweight, making transport and handling easier for the operator.
  • They are very versatile in terms of the variety of metals and fusions that can be used.

MIG welding Machine Features To Consider

Before buying a MIG welder, there are some factors that you should consider to find your ideal MIG welder according to the use you are going to give it and your needs:


As we have done by showing you the best welders, in terms of voltage, we can classify MIG welders into three groups: 110V, 220V, and multiple voltages. The higher the voltage, the more versatility to perform all kinds of work.


Even if the main type of welding used is MIG, some technologies allow the flow of wire feed for aluminum bonding and rod welding types.

Easy to use

The welding quality is determined in equal parts by the welder’s ability and the welder’s capabilities. Therefore, an amateur welder must choose an easy-to-use machine.


A MIG welder that can be transported is ideal to have at home. In this way, it can be used to repair parts outside or lend them as a favor.


MIG welding machines are not cheap, so if you want a MIG welding machine, you should look for one that allows you to carry out the projects you want to do and that offers you the peace of mind of a 3 or 5-year warranty.

Additional Points

  • Have the safety equipment ready to help you keep your body covered by preventing exposure to ultraviolet rays.
  • Choose a comfortable MIG gun. They can be cooled by water or air.
  • Prepare the area where you will weld, avoid flammable materials nearby and look for a good surface to weld.
  • Get the right thread, making sure it is the same material to be welded. For example, if you are going to assemble stainless steel, use a stainless steel wire.

Today, the MIG welding machine is used in many applications within workshops and factories and many people who have hobbies decorating or maintaining the home and, of course, for all those passionate about welding work.

Differences Between MIG and TIG welders

Many people want to know what the difference between MIG and TIG welders is, and although it is usually a matter of taste, we show you the biggest differences between the two:

  • The welding process is different. MIG welding is carried out using metallic inert gas to feed a wire, while the TIG is a rod that feeds the weld pool.
  • Hands-free or not. These MIG welders leave you a free hand to hold the part or for what you need, while for TIG welding, you need both hands when holding the rod.
  • Speed ​​and finish. MIG welding is fast welding that can cover many surfaces, although the finish is not quite good. In contrast, TIG welding is much slower, but the finishes you achieve are much better.
  • Art vs. Functionality. Continuing with the previous point’s comments, the MIG achieves strong welding for large sections, while the TIG is for small parts and perfect finishes.
