What is MIG Welder Used For?
A MIG welding machine (metal inert gas) is used for metal welding devoid of trapped slag in the metal. MIG welding is a unique process that makes use of inert gases or gas mixtures for shielding.
Common shielding gases or mixtures used are helium, argon, oxygen and carbon dioxide. Helium and argon are usually used for welding non-ferrous metals like aluminium.
The process makes the realization of high-quality weld possible because there is no flux is used. The shielding gas helps in protecting the arc so that there won’t be major alloying loss elements loss or weld spatter.
You can carry out the process in many ways, inclusive of fully and semi-automatically, and you can use it for joining various metallic objects along with alloys. That is why both beginners as well as experts are very fond of the process.
However, you can’t perform MIG welding in an overhead or vertical position because the weld pool features a high level of fluid and heat. Moreover, it makes use of complex equipment for the process.

How to Choose a MIG Welder
If you are a beginner, and you want to MIG weld steel or aluminium, getting a MIG welder is not a bad idea. It is an ideal tool for hobby welding, farm/garden equipment maintenance, automotive welding, and so on.
It is easy to learn and produces good looking welds at all times. You don’t need to break the bank to get one, and it is the easiest way to start welding, especially if you are a newbie in this game.
What To Look For: When choosing a MIG welder, you should go for a machine with the provision for fixing a gas cylinder on it. You should avoid machines that can only weld with flux core welding wire. The issue with flux core is that it produces a slag coating on the weld
Power: The amperage produced by welders at a specific duty cycle is used for their classification. The duty cycle is the duration a welder can work within a 10-minute time period without overheating if operated at a certain amperage.
Hence, if you will weld at a high amperage for long periods of time without stopping, you need a machine that comes with a high-duty cycle. This will make it possible for you to get the most satisfactory results at all times.
110 Volt or 220 Volt: You need to be sure of the voltage of your installed electric outlet before making a purchase. However, it is important for you to note that 220-volt welders are more powerful than their 110-volt counterparts.
Ideally, a machine with 110 volts may not be able to weld metals thicker than ⅛ inch in a single pass. It is ideal for hobby welding, and when you are just new to the game.
If you require more power to weld ½-inch thick metal in one pass, you need to go for a 220-volt machine. This means that your installed outlet should support 220 volts.
Spool Gun Capability: A welding machine with spool gun capability enables you to weld aluminium with so much ease. Some machines have this feature while others don’t. With this feature, you only need to purchase an optional aluminium spool gun, connect it, and you are good to go when it comes to welding aluminium.
How To Discover A Great Deal: A good warranty is an indication that you may be in for a great deal. It is important for you to note that welders with low amperage units may only have flux core wire welding capabilities.
The majority of low amperage units do not come with gas cylinder hooking capabilities. This feature is very important if you will need to attach a gas cylinder in the future.
Other Things To Look Out For: The wire speed of the machine you want to buy is very important. The majority of the machines in the market right now come with variable speed so that you can be more flexible with your operations.
Also, you need to check out the safety features of the welder. Features like thermal overload protection, arc force stabilisation, and so on are very helpful in making you safe during operations.
Also, a good product should have accessories that will make your job easier. Some of the popular accessories are clipping hammer, earth clamp, mask, wire brush, just to mention a few.
You should work hard in the aspect of comparing features so that you will be able to discover a perfect product for you. This will make it possible for you to get the most satisfactory results at all times.
Frequently Asked Question
What is a good MIG welder for a beginner?
A good MIG welder for a beginner should come with rich features for effective operations. Features like sleek on/off control power, dynamic wire drive motor, wire feed and gas, amongst others.
Is MIG welding strong?
MIG welding is strong. If you make use of a single pass, you can get a thickness of ¼ at 250 amps. By using the right wire, you can use as many passes as possible so as to get the thickness of your choice.
What equipment is needed for MIG welding?
It requires a perfect wire feed system so that you will be able to get the most satisfactory result. There are three types of wire feed system – add-on, suitcase and spool feed guns.
What is the difference between MIG and TIG welding?
MIG welding makes use of a feed wire that moves steadily through the gun so as to produce the spark, which dissolves to bring about the weld. On the other hand, TIG welding makes use of a long rod for fusing two metals straightly together.
What gas do you use for MIG welding?
The most common gases used for MIG welding are helium, argon, oxygen, and carbon dioxide. For welding, non-ferrous metals such as aluminium, argon and helium are commonly used.
When searching for the best MIG welder under £300, you should digest this piece properly. You need to make a wise investment for the future, hence, you should work towards choosing a machine with enough power for your type of jobs.
