MIG Welders Buyers Guide

You’d be surprised with a wide range of things experts and DIYers can build with metal inert gas welders. From a workbench, tool rack, stool for your garage, to any custom project, a MIG welder can help you do a lot in your workshop.

With a lot of brands, models, and best MIG welder deals on the market, it can be difficult to find an ideal choice for yourself. Therefore, we have reviewed only the best MIG welders carefully selected and tested for you by our experts.

The key difference between a cheap and expensive MIG welder is its ease of use. The usage depends on you – whether you’re a welding professional or a DIY enthusiast.

If you’re worried about all those technical terms like duty cycle, amps, volts that we used above while reviewing these best MIG welders on the market, we’ve got you covered.

Following is your detailed buyer’s guide to buying the ideal MIG welder for your work.


Unfortunately, the quality and prices of the MIG welders are continuously going down over the past few years. With different brands competing to produce a cheaper yet better MIG welding machine, they tend to lack quality and functionalities.

You wouldn’t want to buy a MIG welding machine every few years, would you? A MIG welder is supposed to help you for a lifetime – give or take.

So, what are the best MIG welders to buy in 2021?

Well, the best MIG welder brands are expensive and more forgiving. They have better quality wire feed units, electronics, and most of all accessories that come with MIG welding machines i.e. torch, gas regulator, safety equipment, and more.

The cost cut off from the cheaper MIG welders is done by compromising the quality standards and features. 

In this case, it is not recommended to purchase a MIG welder that is cheaper yet claims to provide high-end welding quality and features.

If you’re a professional welder and come across welding every day, we recommend choosing the most premium MIG welders.

For DIY projects, choose something in between the most premium MIG welders and cheaper ones.

Estimating the MIG Welder’s AMPs

You’ve read this term amps quite a few times on this page only. Do more amps give you better weld quality? What are the minimum and maximum amps limit you should consider?

Well, the number of amps depends on what you are going to weld. Though manufacturers claim varies, here is what our experts have estimated what these MIG welders can.

With butt weld, a 90-amp MIG welder can handle 2.0m steel thickness. Similarly, 110 amp can weld 2.5mm thick steel, 130 amp can weld 3mm thick steel, 150 amp can weld 4mm thick steel, and 180 amp can handle steel thickness of up to 5mm.

Moreover, if you consider the root gap and V, a 90-amp MIG welder can handle 3.0mm thick steel and a 180-amp MIG welder can handle maximum steel thickness of 7.5mm.

Maximum & Minimum Amps That You Need

If you’re working on a hardcore project, let’s say a modern car with a considerably thin chassis, a 130-amp MIG welder will do the job just fine. On the other hand, if you want to weld a range rover or any other heavy-duty vehicle, you will need at least 150 amps.

Similarly, if you’re a DIY enthusiast mostly working on your welding projects, you can get a MIG welder with a minimum of 30 amps. A 30 amps MIG welder can easily weld a 1.00mm sheet. It can also work on thinner sheets up to 0.8mm if you’re being careful and have the technique.

Input Power

The input power is the voltage your MIG welder will consume. It may seem unimportant but note that not every power outlet is compatible with heavy-duty MIG welders.

Moreover, some cheaper and premium welders run at 220 volts. For higher input power, you might need a special power outlet. If you’re a DIYer, a 110 to 140 volts welder will do the job as standard power outlets are about the same range.

Duty Cycle

The duty cycle of MIG welders depends on the model type and manufacturer. It is the time duration that you can weld before your MIG welder overheats.

The duty cycle is one of the most important factors to consider when choosing your MIG welder. It determines the speed and efficiency of your welding machine.

Reading this review, you might have come across phrases “This duty cycle of this MIG welder is 40% at 110 amps” or “this MIG welder has a duty cycle of 20% when operating at 100 amps”.

If you’ve no idea what this means, let me translate it for you.

Let’s say a MIG welder has a 60% duty cycle when it is operated at 100 amps for 10 minutes. It is recommended to estimate the efficiency of welders by taking 10 minutes time intervals.

The above statement means that welder can weld for 6 minutes at 100 amps, and then it will take around 4 minutes break. Sounds good?

Similarly, a MIG welder with 30% efficiency can work for 3 minutes and need a rest of 7 minutes.

In any case, the duty cycle of a MIG welder is the key factor to decide among the best MIG welders to buy in 2021.

Gas Vs. Gasless

As the name suggests, Metal Inert Gas (MIG) welder, you might be wondering the difference between a gas and gasless MIG welders.

Well, a gas MIG welder requires extra gas shielding while a gasless MIG welder uses a flux-cored wire. A gasless welder creates a gas shield with some vapor-forming compounds that prevent oxidation.

Let’s forget the technical terms and science behind this and see what a gas MIG welder and gasless MIG welder can do.

With a gasless welder, you don’t have to clean the surface before welding. It can weld through painted, rusted, or galvanized metal surfaces easily. Moreover, it is portable and easier to carry than a gas MIG welder.

If you have an outdoor workshop, it is better to choose a gasless MIG welder. It can weld easily irrespective of the weather conditions and atmosphere. On the other hand, a gas MIG welder is better suited for indoor welding.

Gasless MIG welders offer enormous strength and penetration for most welding materials. Depending on the techniques used, some can weld even the thinnest metals.

If we talk about the welding position, a gas MIG welder is the better choice as a gas MIG welder can easily handle out of position welding. For example, if you want to weld a vertically upward surface, a gas MIG welder will better serve this purpose.

Gas MIG welders produce less welding fumes as compared to gasless MIG welders. However, with some safety measures and protection, experts can handle gasless MIG welder’s excessive fumes.

Can My Welder Use Flux Core Wiring?

As discussed earlier, MIG welders use a gas cylinder to get the job done. However, the gas cylinder makes the welder heavier and it also becomes difficult to weld outside.

This is where flux core wiring shines.

Fortunately, some of the welders we reviewed above can also use flux core welding. All you need is a flux core wire that has similar elements as that of shielding gas produced when the heat is released from the welder. It will also make the welder lighter and easy to carry around.

MIG Welder Chassis

The Chassis is the case or body of the MIG welder. MIG welders can be heavy and you need to make sure if they have wheels with the chassis. Some MIG welders also come with a gas bottle attached to the rear of the chassis so you need to make sure they are easy to move.

The main things to consider are if the MIG welder has wheels and a gas bottle shelf.

Some 150 amps or below MIG welders don’t come with a bottle shelf but you can easily make a DIY shelf at home. Fortunately, you have a MIG welder now – what can’t be done?


Weight is another small factor to consider while deciding between the above MIG welders list. On average, the MIG welders listed above range from 50-100 pounds.

However, any welder above 50 pounds often comes with wheels to carry around. If not, you can simply purchase a wheeled cart to effortlessly move the welder around.    

Overheating Measures

Modern MIG welders often have cooling systems and on-demand fans that do not let them reach high temperatures.

Moreover, some MIG welders also come with thermal overload protection. This ensures that your welder once reached a temperature, automatically shuts down.

In any case, it is recommended to always use welding helmets and welding suits to prevent any mishaps.   

What Metals Can I Weld with a Metal Inert Gas Welder?

As discussed earlier the steel thickness that MIG welders can weld, the only disadvantage of these welders is that only thin metals can be welded.

Most of the MIG welders on this list can handle half-inch steel at most. MIG welders are often used to weld cars, motorcycles, other types of vehicles, and DIY projects.

The main reason why people prefer metal inert gas welds is its high efficiency, speed, and cost. 


Welding steel with MIG welders is as easy as it gets. However, if you want to weld steel, the welder wire may get jammed in the torch. It is recommended to purchase a spool gun (often sold separately) to prevent these wire jams.
