Best MIG Welder In The Market 2020

MIG welding is the most common form of welding and most of the new welders start their work with MIG welding. However, there are other kinds of welding too such as:

  • Flux cored welding
  • TIG welding
  • Stick welding
  • Plasma cutting

As far as MIG is concerned it is acronym for Metal Inert Gas. Well it is a subtype of the GMAW type of welding which stands for Gas Metal Arc Welding. In MIG welding there is an electric arc produced between the wire electrode and the metal sheet that is to be welded.

The wire electrode is used up in the welding process and therefore needs to be supplied continuously as it keeps melting. This supply of the wire can be automatic or manual depending on your preference. The heat that is produced due to the passing of electricity melts the consumable wire as well as the metal sheet so much so that they melt and fuse together to form a joint that is inseparable.

There is another thing that is important in welding and this a shielding gas. This shielding gas protects the whole area from oxidation by consuming all of the oxygen present in the immediate vicinity of the process. This is different from the flux core welder where the wire is hollow and is filled with flux that prevents oxidation.

When the metal and the consumable electrode come in contact an electric is produced which has enough heat to melt the wire as well as the metal that needs to be welded making it possible for the two to join together strongly.

For the process of MIG welding to take place smoothly there is a requirement of a constant voltage and a DC power source that can be replaced by an alternating current. The whole process requires you to transfer metal on to the surface that is at the same temperature and that needs to be joined. There are four different techniques that can be used to transfer metal such as:

  • Globular
  • Short circuiting
  • Spray
  • Pulsed spray

The main importance of MIG welding is in welding non-ferrous metals such as aluminum but now it is also being used to weld steel and stainless steel. Generally the cost of welding used to be very high due to the high cost of the inert gas like Argon that was used.

But, now the cost has come down considerably since the use of carbon dioxide became prevalent and this has made MIG the most used welding process in the world.

Advantages and Drawbacks of MIG welding

There are many benefits of MIG welding and a few of them have been listed below:

  • Learning is easy: MIG welding is the easiest form of welding and the welders who want to learn do that with MIG.
  • Used for variety of metals: MIG welding is capable of welding many types of metals such as aluminum alloys, steel, stainless steel, bronze, silicon, magnesium, copper, nickel and many other alloys. All you need to take care of it is to use the right kind of shielding gas, the right electrode and the right welding conditions and you are good to go.
  • Can weld metals of varied thicknesses: With MIG you can weld wire of 26 gauge on one hand and thick metal sheet on the other hand without any problem.
  • All position welding: MIG welding can be done in any position. Even the overhead welding gives no problems at all.
  • Neat weld: Since the shielding from oxidation is provided by gas there is no need to remove the slag after the welding process is complete. You will get a neat weld at all times.
  • Quick: MIG welding process is faster as compared to any other type of welding.
  • Aesthetic: The welding done with MIG is more aesthetic as compared to flux cored Welding.

Though MIG welding is the most preferred type of welding but it is still not devoid of some drawbacks and they are:

  • If you are to weld thick metal sheets you will have to carry out the welding process in several phases.
  • There is less control when you are dealing with thicker materials.
  • MIG welding more suitable for indoor welding needs. You cannot use it in farms and open spaces because of the use of gas and the risk of porosity.
  • The equipments that are required for this type of welding are expensive to buy and are far more complex than any other welding equipments.


MIG Welder Equipment:

The MIG welder consists of the following equipments:

  • A welding gun for holding all the units in place
  • A power supply
  • A supply of shielding gas for protecting the welding field from oxidation and helping the weld to be free of any bubbles
  • A feeder system for the consumable wire that will be used up in the process of welding and will need to be supplied at a constant speed

The working of MIG welder:

The welding process requires heat that melts the metal which then fuses to make a joint. However, this heat is produced by the short circuit. This heat then causes the metal electrode (consumable wire) to melt and it is placed in the desired location of welding by techniques like globular, short-circuiting, spray or pulsed spray.

When the gun is shut down the metal starts cooling and a joint is created fusing two pieces into one. The consumable wire is fed into the gun automatically or in the semiautomatic machines manually.

The quality of the joints:

The joins formed by MIG welding are more supple and smooth. Their strength is also more as compared to other forms of welding. There is little or no distortion caused when you use MIG welding. Since the joint is smooth you need not do a lot of polishing.

You can even join two dissimilar metals but you must select the electrode metal such that it has properties close to both the metals being welded. The speed of welding is greater with MIG welding as compared to other welding methods because of many reasons such as there is a constant feeding of wire during the process. This will not require you to stop your welding every now and then making it more efficient and time saving.


What Features Should a Good Metal Inert Gas Welder Have?

You will find a lot many models of MIG welders in the market that you can choose from and all of them claim to be the best. But, it is important for you to get your hands on the best MIG welder for your needs. For this you need to do a little home work and need to read about the best MIG welders available in the market and their reviews. This will help you make the informed decision and choose the best MIG welderone for you.

When you want to buy Best MIG Welder in the market 2018 you must know something about what a good welding machine must have. These are:

Input Power:

The welding machine works on power. The more power the machine uses the more voltage it will require. Generally the machines come in a voltage range of 110-120. If you are sure that you will need the machine for minor repairs and welding of thin metals sheets then you can go for low voltage welding machine.

But, it is always better to choose a machine that can deliver in low as well as high voltage because you never know what work you may require to do. For this you will need a machine that has a feature of adjustable voltage. Such machines give you a lot of freedom of choosing the thickness of metal that you want to weld.

Heat Overload Protection:

This is a very important feature that you must seek in your machine.  Though this feature is very important, you will encounter many welding machines that do not have this feature. The overheating of a machine could be dangerous not only for the machine but also for you and the place where it is kept. There should be an auto shut off mechanism so that in case of overheating the machine shuts off by itself.

Duty cycle:

This is also an important feature that you must look out for because it will tell you about the time that you can operate the machine for, continuously. This is measured in an increment of ten minutes. If your machine has duty cycle of 30%, it means that you can use the machine continuously for 2 minutes and then you need to give it rest.

Higher the duty cycle faster you will be able to complete your work. This also means that you must not work longer than the recommended duty cycle of the machine at a stretch because that may lead to unnecessary heating up of the machine and therefore damage to the important parts reducing the durability of the welder.

Material Thickness that can be Welded:

When you buy a welding machine you do not expect it to weld only a certain thickness of metal. This is why most of the welders are given with settings that can be adjusted for a particular metal thickness.

However, knowing about the maximum and minimum thickness of metal that can be welded will only help you keep your machine working for long without repairs. Being able to adjust the machine to weld a wide variety of metal thickness will only help you in expanding your work. After all you cannot buy different machines for welding different metal thickness:

The weight:

Whether it is your business or your hobby if your Best MIG Welder in the market 2018 is so heavy that it cannot be lifted or carried anywhere else then it is just a waste of money. But, if you just want to keep the welding machine in your garage and work with it occasionally then it would not be much of a problem whether or not it is heavy. However, if the machine has one handle and is modest in weight so that it can be carried by two people, it would just be an added advantage.

Wire size and wire type:

When you buy a welding machine you must keep in mind that the welding machine will determine your choice of wire. There are two most commonly used types of wire that you can work with while welding and they are:

  • ER70S-3
  • ER70S-6

ER70S-3 is used in conditions when the metal surface that is being welded is dirty or has rusted. This wire is designed to give out more of the deoxidizing substances and hence results in a joint that is strong and supple.

ER70S-6 is more of an all purpose wire and is used in all kinds of welding needs. It has moderate amount of deoxidizers and it is better to be used on surfaces that are clean and fresh.

However, when you buy a welding machine you must make sure that you can use both kind of wire for welding or the kind that will more aptly suit your needs.

Easy to use:

The welding process is not very complicated one but if the machine has not too many buttons it would be easier to use. The coloured knobs, digital displays and a handy-gun would make your work easier and more fun. When you are busy welding, you will not want to get confused with too many buttons or knobs that are similar looking. This is definitely going to affect your efficiency and cause delay in work.

When you are out in the market to buy a welding machine you must read through the MIG welder reviews.These reviews will help you find the Best MIG Welder in the market 2018.
