Best MIG Welder for The Money 2018 – Reviews and Buying Guide

Looking for the best MIG welder?

With this post, you will discover the best models, learn how to use them correctly and safely, and discover lots of interesting facts about welding.

Getting a high-performing welder always pays off through faster work and more effective joints with minimal scrap.

Whether you intend to purchase a new MIG welder or replace the one you have, I am here to help you get one that suits your needs and goes easy on your pockets.

I will also show you how to seek out the best one but first, for the sake of beginners, let’s define an MIG welder.

What is an MIG Welder Anyway?

Before we dive into that, it’d be good to know a thing or two about arc welders.

Arc welders join different pieces of metal using high-voltage electricity, with enough heat to melt the metals and make a weld.

There are various types of arc welders, such as TIG, stick, MIG, and so on. The difference between these welders is in how the arc (the luminous discharge) is maintained and shielded.

With an MIG welder, the tank is normally filled with a gas mixture dubbed the Metal Inert Gas. Usually, the gas mixture doesn’t react with the metal, and thus it doesn’t add contaminants into your weld.

The gas mixture gets pumped from the tank through the welding cable and emerges through the same nozzle that’s connected to your welding wire. This enables the formation of a protecting cloud around the luminous discharge as you weld.

Note: some welding wires will have flux inside. Though this eliminates the need for an external gas tank and works just fine, it doesn’t deliver the same quality and power you’d get from a separate gas tank. Mary Helped me to knowing this fact.he write an article about essential mechanic tools set on his blog.

Now, let’s look into the best MIG welders in the market.

“What should I look for when buying an MIG welder?” – the section below will help you select the right MIG welder for your needs.

Thing to Consider Before Buying MIG Welder:

Be sure to check for the following qualities when shopping for an MIG welder.


There are 2 factors under power that you ought to consider:

  • Power Output

The foremost factor you should consider is the power output you’re targeting. Do know your ideal power output you need to think about the kind of welding you will be doing and how frequently you will be doing it.

Looking to do small projects with thin metals at home? 100 amps is enough. Nonetheless, who knows if a need will arise that will require you to weld thicker metalspieces? That’s why it’d be better to provide for that possibility and get a welder that can deliver a maximum of 140 amps.

Also, you ought to consider the minimum power output.

The best MIG welder for home use will have minimum power outputs of about 30 amps. This is okay for 19-guage metal but what if you need to weld something extremely thin, say 8 mm? In that case, you should be looking for an MIG welder with minimums of around 20 amp.

  • Power Input

You might want to get something that requires little to deliver a lot. That means that input requirements should be lower than the output. This helps to reduce the electricity costs.

Normally, a 140-amp MIG welder will require 120 volts to power. Input requirements will obviously increase with increase in output.

Duty Cycle

How long can the machine run without overheating?

Duty cycle means the amount of time within a duration of 10 minutes that the welder can run without overheating.

The duty cycle is usually expressed in seconds. For instance, you might find it written “20% @ 100A”. That simply means that the welder can run for 2 minutes at 100 amps before it requires an 8-minutes rest.

Usually, a lower power output allows you to weld for longer without requiring rest. For example, a machine that deliver 80 amps might run for 4 minutes, requiring a rest of 6 minutes only. The vice-versa is true.

The duty cycle aspect is something you should always keep in mind if you want your machine to last a long time.

High-quality MIG welders come with built-in protective systems that shut them off automatically once the duty cycle ends. Of course, such welders will cost you more than ordinary ones.

Feed Speed

Feed speed refers to the speed at which the machine feeds the welding wire to the gun.

If the speed is too low, the wire will disappear when it touches the metal, resulting in an unsightly, uneven, and inadequate weld. 

On the other hand, if the speed is too high, the wire will stretch from the gun. You will be left with too much wire, and this will result in droplets of molten metal at the site of the weld or what welders call spatters.

The ideal feed speed is the one that has the wire going through just quickly enough to deliver a constant arc. In such a situation, a nice sizzling sound is made.

Cheap machines normally come with separate feed speed and power settings, meaning you will have to play around with the values to set the perfect speed. This is easy to do but it will definitely take some practice.

If you don’t want to take chances with the quality of your weld, it’d be better to go for higher quality MIG welders, as they come with automatic speed settings. The speed gets adjusted automatically based on the power.


MIG welders range anywhere between 40 and several hundred pounds. Usually, bigger machines have higher power output and more features (and note, I said usually, not always). But -

How much space do I have? Do I need to shift the welder’s location from time to time?

Those are the questions you should be asking yourself.

Got limited space? Then you need to consider the size and weight of the machine carefully.

Don’t be fooled by size. Some small machines will deliver much higher power than bigger ones. For instance, the Millermatic 211 weights less than 40 pounds but delivers 230 amps. The Hobart handler 140, which is heavier, at 57 pounds, delivers 140 amps. See the contrast?

With that said, it’s clear that you can have high power with a small machine. It’s all just about the features.

Safety Features

Great MIG welders have built-in safety features to keep you safe from harm. These features include:

Thermal Overload Protection – helps to keep you from going beyond the appropriate duty cycle. It automatically shuts the machine at the end of the cycle to prevent overheating. Though not all machines come with this feature, it’s super helpful especially if your mind wanders. It also helps to prolong the machine’s life.

Built-in Contactor – instantly cools down the wire till the trigger is pulled. Therefore, you can easily shift positions without worrying about accidental contact with your body.

Shielding Gas

I bet doing high-quality welds is your target, right? That is why it’s crucial for you to select the right shielding gas. Remember, shielding gas is the component that keeps that arc of luminous discharge intact.

Here are the main types of shielding gas:

  • Carbon Dioxide (CO2) – it’s the most inexpensive and common. You can use it in its pure form to weld thicker metals and achieve a deeper weld penetration. Or, you can use CO2 mixed with other gases to make your arc more stable and minimize spatter.
  • Oxygen (O2) – this one is often mixed with other gases, especially argon. It comes in handy to improve the weld pool fluidity. This helps to achieve deeper penetration and eliminate undercutting.
  • Argon (Ar) – argon is denser than air, and thus it’s able to protect the welding spot from contaminants in the air. If you seek a high-quality weld in terms of strength and appearance, it’d be good to go for a mixture of Ar and CO2. That way, you will have a more stable arc with minimal spatters.

If you’re looking to weld non-ferrous metals such as aluminum, copper or titanium, it’d be better to use pure argon.


Some machines will offer you both gas tank and flux options. That way, you can handle your projects confidently, as you have back up. If the gas is finished, the flux backs you up.

Remember, flux-cored welders do not require extra shielding gas as there’s already some gas in the welding wire.

Of course, the dual option will cost you more, but for flexibility, I’d say it’s worth it.


This is pretty straightforward. The MIG welder should have a warranty of at least one year but three to five years would be much better. Go for a model that has a clear return policy so that if there are any problems with the machine (which will normally become apparent in the first few months), you can just return it and get another one or a refund without hassles.

The good thing with buying from Amazon is that you get an automatic 30-day return cover if the order was fulfilled by Amazon.  

Types of MIG Welding

MIG entails the use of heat to transfer metal from the electrode (which is the welding wire) to the metal pieces being welded. That is part of what makes MIG welding unique.

There are 4 main types of transfer that you can make use of to get that weld. Each of these results from the voltage you set and the shielding gas you use. That is why it’s important to know how your choice of voltage and shielding gas affects the transfer type you achieve.

Let’s look into each of them briefly.

  • Short Circuit Transfer

This transfer happens when the welding wire comes into contact with the metals you’re welding. Electric current from the gun flows through the welding wire, creating a short circuit.

As a result, the wire heats up and dribbles onto the metals you’re welding. Multiple drops are released at a very fast pace, creating a crackling sound, more like frying broth in an extremely hot pan.

To achieve a short circuit transfer, what you have to do is set the machine to low voltage and use CO2(carbon dioxide) gas (pure or in mixture form).

One obvious advantage of using short circuit transfer is that the needed shielding gas is relatively inexpensive. However, you can’t use this transfer type to weld thick metals.

Short circuit transfer can only handle thin/sheet metals with a thickness of not more than an inch.

Use it on a metal that’s thicker than an inch and the weld will not penetrate the joint properly.

  • Globular Transfer

This one is a lot like the short circuit transfer, only that the intensity and speed of the drops of molten wire are different. With globular transfer, the welding wire will melt and collect into a glob at the tip of the wire. Therefore, the molten wire drips onto the joint at a slower pace.

In the process, globular transfer pops are produced, rather than fast crackling sounds.

To achieve this type of transfer, all you have to do is set the machine to high voltage and use argon (pure or in a mixture) as shielding gas.

The good thing about globular transfer is that it can weld thicker metals.

However, it’s not easy to control the drops, and thus spatters can result.

  • Spray Transfer

This one occurs when the wire melts and releases very fine drops and sprays/mists into the joint.

If you’re doing it right, then you will hear a hissing sound as opposed to crackling or popping sounds. Another trait of a good spray transfer is a neat arc (luminous discharge) from the gun to the joint.

To achieve a globular transfer, use high voltage electricity coupled with argon (or argon gas mixture) as shielding gas. Note that if you’re using argon gas mixture, CO2 shouldn’t make up more than 15% of the mixture, as this will result in globular transfer.

Spray transfer is ideal for welding thick metals, as it penetrates deep and doesn’t leave spatters. The only problem is that the shielding gas is quite expensive.

  • Pulsed Spray Transfer

With this transfer, you can set the welder to pulse the voltage rather than allowing the normal steady voltage flow.

The result is that the transfer keeps alternating between globular and spray transfer.

As the voltage is pulsed, it does not need to be as high as the one pure spray transfer would require. The benefit is that much less heat is applied to the weld, thus creating a smaller, cleaner weld pool.

This in turn gives you flexibility with the weld spot, and that’s why it’s perfect for welding difficult objects like pipes. The most notable disadvantage is that the welders that offer you such a function are quite costly.

Advantages of MIG Welding

There’s one thing that you have got to keep in mind. The advantages of MIG welding are determined by the MIG welder you’re using and the nature of the job you’re doing. All in all, here are several upsides to MIG welding that are common to almost all MIG welders and welding job natures.

  • Higher productivity

With MIG welding, you’re able to save time as you don’t have to keep changing the rod or chipping away slags. Also, you don’t have keep brushing the weld.

You’re able to work faster and more neatly.

  • Inexpensive equipment

You only need to make an investment of600 dollars (or less) for buying a good welding machine. Add a few more bucks for the welding wire and the shielding gas and you’re good to go.

You just need invest less than $600 in a welding machine from such reputable manufacturers as Lincoln Electric or ITW. Adding some dollar for shielding gas and Mig wire, you are welding for $700 or less.

As a matter of fact, out of all the welding processes, MIG is the one with the least expensive consumables. The MIG welding wire will cost you $3 or less.

  • Low spatter levels

By using the right mode of metal transfer, you can weld without any sight of spatter. All you have to don is know how to balance voltage and shielding gas type according to the type of metal you’re welding and its thickness.

This advantage is linked to another advantage – unlimited thickness. With short circuit transfer, you can weld thin/sheet metals while with a different mode, say spray transfer, you can weld thick metals.

  • Welds a wide range of metals

By using different types of shielding gas, filler wire, and voltage levels, you can weld just about any metal from stainless steel, to aluminum, to nickel and carbon steel, and more.

  • High deposition rates

Compared to other welding processes, particularly stick welding, MIG is able to makes bigger deposits of weld metal. With MIG, you can deposit around 10 lbs. every hour.

  • Easy to learn

The concept of MIG is easier to grasp than that of stick or TIG welding.

It took me just a few minutes to learn the basics and around 3 hours to learn how to do it; I believe you can do it too. In fact, it’s not a must to have an instructor. You can just watch a few videos on YouTube and you’re good to go.

  • Neat and efficient

The purpose of the shielding gas in MIG welding is to protect the arc. For that, alloying elements are rarely lost during the metal transfer process. Therefore, as opposed to other welding methods, especially stick welding, there is no slag to remove.

Furthermore, only minimal amounts of spatter are produced. This means that you only have to do a little clean up and get back to the job.

  • High electrode efficiency

With MIG, there’s a high electrode efficiency – 93 to 97 percent normally. Therefore, when you purchase a 100-pound MIG welding wire, you’re able to deposit 93 to 97 pounds.

A process like stick welding has just around 65 percent efficiency.

Can you see the difference?

  • Great welds

Looking to achieve a nice-looking weld? Then you’ve to consider using MIG welding. This method gives you a finer visibility of the weld pool and with an auto-feed wire, you have better control.

Consequently, there are also minimal spatters, and thus the results are great.

Wondering how to do proper welds for great results? This is what the next section is about.

How to Use MIG Welders Properly

There are so many ways in which you can use MIG welding. You can use it in your auto shop, garage, or even at home for small repairs and DIY tasks. Following the stepsbelow will help you do great welds.

Step I: Prepare to Weld

There are various preparation steps you need to go through, as follows:

  • Assemble your protective gear.

You’ll need the following safety equipment to ensure you’re well protected during the weld:

  • Gloves
  • Masks
  • Protective suit

Ensure that all your skin is properly covered to avoid getting exposed to UV rays. Your mask should have a dark shade to protect your eyes from that intense light.

Working in an area that is not well ventilated? Then you will need a vapor mask to keep yourself from inhaling hazardous gases.

Wearing gloves protects the skin on your hands from molten metal.

PRO tip: keeping a bucket of sand or a fire extinguisher nearby will help you deal with emergency fires.

  • Get a good MIG gun.

Some are shaped like acetylene torches while others appear like pistols. Also, some are cooled with water while for others, air is enough.

Usually, air-cooled MIG guns are used with machines delivering not more 200 amps. Such guns are easier to control. If you’re doing small welding projects at home, I recommend you go for an air-cooled gun.

  • Prepare the welding area

Get rid of any flammables and find a good surface on which to do the job.

I suggest putting a ground connecting on the material you’re welding to steady it.

Are there people present in the area? If so, use welding curtains to protect them from the UV rays.

Step II: Get the Right Wire

Be sure to use a welding wire that’s of the same material as the item you’re welding. For instance, if you’re welding aluminum, use an aluminum wire.

If you’re welding steel, you can have two wire choices:

  • AWS ER70S-3 – this one is multi-purpose and it’s the most cost-effective option.
  • AWS ER70S-6 – this is high-grade steel wire that’s meant for dirty or rusty steel.

There’s another common welding wire – E71TGX. This one doesn’t need shielding gas and it’s suitable for welding in windy conditions and on rusty or painted objects.

How thick is the object you’re welding? Make sure that the welding wire is relative to the thickness of the material you’re welding. If the metals you’re welding are thin, then use thin welding wire. If, however, they’re thick, then use thick welding wire.

Step III: Prep the Reel

Tighten the reel to prevent the wire from unravelling from its tension. Also, straighten the wire’s first 3 inches to prevent formation of twists or damage to the feeder.

You can utilize a wire cutter to trim the wire appropriately.

Step IV: Feed the Welding Wire

Before you feed the wire, you want to make sure that it’s clean and without grease or rust, as these impurities can cause bad welds. You can clean the wire with a dry piece of cloth before feeding it.

So, insert the welding wire into the wire liner and feed it to the roller.

Having trouble inserting it? Are you having to use force? Chances are, the wire isn’t aligned properly.

As soon as you’ve fed the wire, turn on the welder and utilize the feed mechanism to force it through the welder.

Adjust the tension to the right level. Extreme tension might bend the mountings, thereby ruining the welder. Therefore, keep it at the minimum level that holds the line in place while still allowing it to be fed through.

Tension at both the feeder and the reel should be as low as possible.

Remember, if you leave the wire in the welder in there when you’re not using the machine, it will rust.

Step V: Make the Weld

Time to start welding. As you do this, maintain a constant electrode length. Ideally, the electrode should be kept around a quarter inch from the contact tube.

That way, your weld will be clean and regular.

Here are a few other tips to help you make a great weld:

  • Use proper shielding gas – for details, on this, refer to the part about “types of MIG welding” above.
  • Use the push or drag technique to do the weld –in both techniques, the angle shouldn’t be more than 10°. Be sure to keep the welding wire at your weld pool’s anterior edge. That way, you will have more control.
  • With the drag technique, you pull the bead along with the wire’s tip. That gives you a deep penetration and a narrow bead.
  • With the push technique, you push the bead with the tip. This results in a wide bead.

Here are the types of weld you’ll be making

  • A level/flat weld

Ensure that you deposit into the joint directly. You can go back and forth to fill larger gaps. For a flat joint, hold the welding gun at an angle of 90°.

  • A horizontal weld

Lower the gun angle a little to prevent sagging of the filler. The amperage for this weld is the same as that of the flat weld.

Here, you can also use the back-forth movement to fill big gaps.

Is the weld pool getting too large? No worries. Just use a somewhat thinner welding wire.

  • A vertical weld

If you’re welding thin metals, begin from the top, moving the weld pool down with the gravity. That way, the arc will not penetrate the metals you’re welding.

If, on the other hand, you’re welding thick metals, begin at the base, going upward. This technique helps to boost penetration.

In this case, you might want to reduce the amperage by about 10 to 15 percent to battle gravity.

  • An overhead weld

Utilize typical welding styles but raise your speed to prevent the filler from dropping out of the joint.

You may also want to increase the gas flow rate.

When making an overhead weld, make sure that the nozzle stays clean, as the spatter will accumulate faster.

Step VI: Finishing the Weld

When you’re done, rub off the excess filler.

In case there’s a critical issue with the weld, just grind it out and weld the joint again.

Safety Issues When Using MIG Welder

Unlike other welding processes, MIG is associated with very specific safety issues.

Don’t worry, this welding method is actually quite safe when you do it right. But, doing it wrong can lead to the user getting burned badly.

Before you starting welding, it’s crucial that you get the following protective equipment:

  • Welding helmet with dark shade to safeguard your eyes against the harmful UV rays.
  • Safety glasses to shield your eyes from spatter and sparks.
  • Leather gloves to insulate your hands against heat and electric shock.
  • Protective suit made from fire-proof materials to protect your body from UV radiation and heat.
  • Leather boots to safeguard your feet against molten metal and sparks
  • Good ventilation to remove the welding gas

Pro tip: use a good sunscreen to protect areas of your skin that aren’t covered by clothing.

There are 2 extra safety concerns regarding MIG welding:

  • The wire feeder
  • The shielding gas

Wire feeder safety concerns

When you’re done welding, a drop of molten metal is normally left on the electrode stick-out. This drop can penetrate your welding gloves easily and come into contact with your skin. Just be vigilant and get rid of it before that happens.

Then, when you’re changing the MIG tips or the welding wire, be careful not to press the trigger, as that can cause the wire feeder to shock you.

Lastly, when you place the MIG gun down, ensure that there’s nothing leaning against the trigger, as that can result in a fire or a short circuit.

Shielding gas issues

Shielding gases are denser than air, and for that, they fill the work spaces like water fills a bucket – from bottom-top.

When they reach your breathing zone, they will make you suffocate unknowingly.

Suddenly, you feel extremely tired and pass out.

However, the risk depends on the type of shielding gas you’re using. For most applications, Argon-based gases are used, and these are denser than air. These are, unfortunately, the most hazardous type of shielding gas.

Welding fumes are bad for your health. The worst ones result from welding aluminum and stainless steel. These are known to cause cancer later on in life.

To protect yourself from shielding gas problems, be sure to weld in a properly-ventilated area.

MIG Welder Vs TIG Welder

When welding, the method you choose is as important as the equipment you use. Using the wrong method can be like trying to saw a log of wood using a kitchen knife. Can that work? Yep, I don’t think so.

If you’re a beginner, there’s something you should know. Different materials will need different welding techniques, and some techniques are a lot more suitable than others.

How do I know which welding method is right for a particular task? Great question!

First, I know you may have heard that there are two main welding methods – TIG and MIG. Of course, there are others, like stick, but we shall center on those two for today.

To help you get a clearer picture of the more beneficial method for your task, I will elaborate each process.

MIG (Metal Inert Gas) Welding

The best thing about MIG is that it’s very easy to learn. You can learn the basics in an hour and master it completely in a week or so.

The complex sides to this process are in choosing the right shielding gas and setting the correct parameters for your task. Nonetheless, once you take care of that, the method is essentially hassle-free.

How it works

You use spool gun to lay the weld. The gun feeds a coiled welding wire at a consistent speed, which you normally have to pre-set. The spool gun emits a shielding gas to protect the arc, the electrode, and the weld area from air.

Advantages of MIG:

  • You can use it to come up with a strong, beautiful joint without requiring much cleaning or sanding.
  • By using a shielding gas, you can weld at a continuous rate, making the process relatively fast.
  • You can use it on any metal surface and you can weld metals as thin as 26-gauge.


  • You can hardly use it outdoors due to the hazardous gases involved.
  • Though you can weld virtually all metals, different metals need different welding wires and shielding gas types.

If you’re looking for the fastest, easiest welding process, MIG is the method for you. Also, if you’re looking to go professional, an MIG welder would be the best choice for you.

TIG (Tungsten Inert Gas) Welding

Looking to do the cleanest weld? Nothing bests TIG.

As far as beauty is concerned, TIG happens to be the best. As a matter of fact, welding professionals normally prefer TIG for the associated precision and overall neat appearance.

How it Works

As opposed to MIG, TIG doesn’t use a metal electrode; it uses a non-consumable tungsten electrode instead.

The electrode normally needs extremely high temperatures to melt, and for that, extra filler is normally required. You normally have to feed the filler into the weld area using one hand as you operate the torch using the other hand.

Also, as you weld, you usually have to utilize one of your feet to operate a control pedal to determines the heat input.


  • Produces very clean and beautiful weld
  • Allows you lots of control


  • Much harder to learn than MIG
  • Demands lots skill and attention, as you have to use both the hands and feet simultaneously
  • A lot slower than MIG
  • The welding surface has to be totally clean and spotless – you have to remove all rust, paint, and debris

Bottom line

Your choice between the two welding processes depends on what you’re targeting. If your goal is speed, cost-effectiveness, and simplicity, go for MIG. But, if aesthetic value is your biggest priority, go for TIG.

Let’s now look at some of the most frequently asked questions and you might just get the answer to something you’ve been wondering about MIG welding.

Frequently Asked Questions (FAQs)

  • What is GMAW?

GMAW (acronym for gas metal arc welding) is a welding method whereby an electric arc is created between the workpieces and a consumable wire electrode. The arc heats up the workpieces, making them melt and consequently join.

  • What gas should I use with a MIG welder?

Go for carbon dioxide (CO2). This gas is the most commonly used shielding gas and the only one that you can use in its pure form. Also, it’s the cheapest one.

  • Do I have to use gas with a MIG welder?

Normally, you have to use a shielding gas, to protect and stabilize the arc. However, if you’re using a flux-cored welding wire, you don’t need a gas tank.

  • What is the difference between a TIG and a MIG welder?

The major distinction is that one process, MIG, uses a continuous wire feeding system, while the other, TIG, uses a long welding rod and slowly feeds it into the weld pool. MIG stands for metal inert gas while TIG stands for tungsten inert gas.

  • How much gas does my MIG welder need?

The gas flow rate is measured in cubic feet per hour (CFH). Contrary to oxyfuel welding, the flow rate for MIG is very low.

While welding, the gas pressure in the hose is around 4 to 8 psi.

  • Should I use MIG or TIG?

That depends on what you’re looking for. If speed, low cost, and simplicity are your main goal, use MIG. On the other hand, if you’re looking for a very clean and attractive weld, go for TIG.

  • How fast can I learn MIG?

MIG is a relatively easy welding process compared to other welding processes. You can learn the basics in minutes and master the art of MIG welding in a week.

  • Can I weld aluminum using MIG?

Yes. MIG is applicable for all sorts of metals, ranging from steel to nickel and even aluminum. However, you need to ensure that the welding wire you’re using is made from the same material as the metal you’re welding. So, if you’re welding aluminum, the welding wire should be made of aluminum.

Final Word

MIG is virtually the easiest welding process on the planet. You can learn the basics in minutes and master the whole art of MIG welding in a few days or a week.

That is what makes MIG the ideal welding process for your DIY projects.

MIG welding machines are not created equal. While some are incredibly good, others are just terrible. To avoid the terrible ones, go through my list of the best MIG welder reviews.

Having tested and used many MIG welders (and listened to what people say), I believe those are the best MIG welders for your money, so go through them and pick the one that suits you best. Fortunately, they’re readily available on Amazon.
