How to Choose the Best MIG Welder?

By now you’ve probably decided that MIG welding is the way to go. The next step is choosing which welder to buy.

When it comes to buying a MIG welder, deciding which one is right for you can seem overwhelming at first. What brand should I get? How much power do I need? What features should I look for? How much money should I spend? These are all factors you need to consider. Below you’ll find everything you need to know about buying a MIG welder but if you don’t want to read all the way to the bottom, take a look at this handy video. He sums it up nicely.

Advantages

Easy to learn – It’s the go-to process for beginner welders. MIG welding uses a consumable wire electrode that is fed from a spool so you just point the gun at the spot you want to weld and pull the trigger. Learning to MIG weld takes just a few hours but to master it you’ll need a bit more time. If you don’t have a lot of time to invest and just want to learn welding as a hobby or for some minor home repairs, this is the way to go.

Produces a uniform weld bead – MIG offers much better weld pool visibility. Coupled with its simplicity and increased control provided by the auto-feeder you’ll get a solid, clean weld every time.

Clean and efficient – Because MIG uses a shielding gas to protect the arc there is very little contamination to the outside elements like oxygen, hydrogen or nitrogen which can cause a variety of problems including holes within the bead and excessive spatter. There is no slag to clean up so time spent chipping and brushing can be spent welding instead.

Versatile – It’s an incredibly versatile process which can be used to weld a variety of metals including aluminum, copper, stainless steel, mild steel, magnesium, nickel and iron. In addition to being the ideal process for at-home projects it’s used in plenty of other industries that depend on strong, clean welds.

 Higher productivity – The continuous wire feed allows for much faster welding and because you don’t have to constantly change rods or chip and brush away slag you’ll be able to get much more done in much less time.

Disadvantages

Cost – The cost associated with MIG welding is higher than other processes. You must consider the initial cost of the machine as well as consumables like shielding gas, electrodes, replacement tips and nozzles. It can add up quickly.

Depends on environment – MIG is not typically suitable for outdoor welding. Because it relies on shielding gas for a nice clean weld. Any hint of wind will blow the gas away and contaminate the puddle.

Unsuitable for thicker materials – It is best suited for thin metals. If you’re welding thicker material you’ll need multiple passes or even a change of process.

What will you be welding?

You need to consider what type of welding you will be doing. Will you be doing mainly small home repairs like fixing bikes or cars or will you be doing big industrial projects? Below is a chart to help you figure out what amperage you’ll need for common welding tasks.

Miller also has a great calculator on their website to help you find the exact amperage you’ll need depending on the material.

Project Average Metal Thickness Required Amperage*
Auto Body 3/16-inch or less 190 or less
Trailer frames and fencing 1/4-inch to 5/16-inch 200-250
Farm, ranch and landscape 5/16-inch to 3/8-inch 250-300
Bicycles and lawnmowers 1/16-inch 100
Boats, cars and motorcycles 1/16-inch to 1/8-inch 100 – 170
General to heavy repair 3/16-inch to 1/4-inch 190 – 200
Thick structural components Over 3/8-inch 300 or more

* These are only rough estimates if you’re welding with steel. Use the calculator for a more accurate number.

What you need to consider:

Power

Output

The first thing you’ll need to look at when buying a MIG welder is the power output so it’s important to know what type of welding you’ll be doing and how often. If you’re just doing small at home projects with thinner metals 100 amps will suffice. Having said that, you never know when you’ll be welding something thicker so it’s better to spend a few extra dollars and get a rig with a maximum 140 amps.

You should also look at the minimum power output. The best MIG welder will have a minimum of around 30 amps which is okay for 18 gauge metal but if you plan to weld extremely thin sheet (22 gauge/ .8mm) look for something with a minimum output of 20 -25.

See the chart above for estimates on common projects.

Input

For a typical 140 amp welder a standard North American 120V outlet will be sufficient enough to power it. If, however, you plan on getting a bigger machine you will likely need to install a more powerful outlet.

Duty Cycle

This refers to the amount of time within a 10 minute period that you can continuously run the welder without it overheating.

For example: above on the Hobart Handler 140 you’ll see 20% @ 90A. That means you can weld for 2 minutes at 90 amps before you need to rest it for 8 minutes. The lower the amperage the more time you’ll be able to weld without stopping and vise versa.

This is extremely important to keep in mind if you want to keep your welder long term. Some of the best MIG welders have a built in protection system that automatically shuts off after reaching the maximum cycle but you’ll also pay a lot more.

Feed Speed

The feed speed is just as important as power. It has to do with the speed at which the wire is fed through the machine to the gun. Too slow and the wire disappears as soon as it touches the metal creating an ugly, uneven and insufficient weld. Too fast and the wire will extend from the gun leaving you will far to much wire and a lot of spatter. The perfect speed will have the wire going just fast enough to give you a constant arc and will make a satisfying sizzle sound.

Cheaper MIG welders will have separate power and feed speed settings so you’ll have to play around on a piece of scrap to get the ideal speed. This takes some practice but once you figure it out it’s easy to do.

The best MIG welder will have an automatic speed setting which adjusts the speed relative to the power. There’s often a manual override in case you need to make some small tweaks.

Portability, Size and Weight

This is really an afterthought compared to the welders performance but if you have limited space available take note of the size and weight. They can range anywhere from around 40 lbs to several hundred pounds depending on the the power and features.

But don’t let the size fool you. Many smaller welders can pack a huge punch. Just take a look at the Millermatic 211: it weighs under 40 lbs and has a power output of 230 amps. Compare that to the Hobart Handler 140 at 57 lbs with an output of  140 amps. It all depends on what kind of welding you will be doing.

If you plan on moving it around regularly, carts are available to make your life a bit easier so you don’t have to strain yourself before you even start to weld. This is especially useful for auto body work and need to move around the car easily.

Safety Features

The best MIG welder will come with built in safety features to protect you from harm so you can keep welding for years to come.

Thermal Overload Protection – This is so you don’t go over the recommended duty cycle limit. If your welder has a duty cycle of 40% at 150A, after 4 minutes the welder will automatically shut off to prevent overheating. Not all welders have this feature but it’s incredibly useful if your mind tends to wander. This feature will protect your investment and increase the life cycle of your machine.

Built-in Contactor – This makes it easier to change position without having to worry about making accidental contact. The contactor keeps the wire electrically cold until you pull the trigger.

Shielding Gas

Choosing the right type of shielding gas is vital for a high-quality weld. It’s what puts the G in MIG. There are several different types of gas depending on the material you’re welding. The 4 most common are:

Carbon Dioxide (CO2) – is the cheapest and most common of the MIG welding gases. It can be used in its pure form when welding thicker materials for deep weld penetration but is often mixed with other gases to produce a more stable arc and less spatter.

Oxygen (O2) – is mixed with other gases in small amounts  – around 5% or less. It improves weld pool fluidity for better penetration, a nicer weld bead and no undercutting. It’s typically mixed with argon for carbon steel, low alloy steel and stainless steel.

Argon (Ar) – is heavier than air so it protects the weld from the air which would otherwise contaminate it. For a high quality weld in both appearance and strength a mixture of argon and carbon dioxide is recommended. It offers better arc stability, puddle control and less spatter. For non-ferrous metals like titanium, copper, nickel or aluminum 100% argon is used.

Helium (He) – is the least common and most expensive of the gases and is better used for TIG welding. For MIG welding it provides a wide bead with poor penetration.  It is always mixed with other gases and is commonly used on non-ferrous metals. If welding with stainless steel it is usually mixed with argon and carbon dioxide.

Multipurpose

Some of the best MIG welders offer both MIG and flux-cored options so you can tackle any project with confidence knowing you have the right tools for the job. With flux-cored welding you don’t need addition shielding gas because the gas is embedded in the wire. You’ll pay a bit more for the dual option but for the versatility it offers it’s well worth it.

Warranty

Buying the best MIG welder is a pretty hefty investment so a solid warranty is key. At the very least you should look for a warranty of 1 year but preferably 3-5 years. Usually any flaws in the welder will become apparent within the first few months but it’s always nice to know that you’re protected in anything goes wrong further down the line. Also keep in mind of the return policy so if it breaks within the first few weeks you can return it hassle-free. Amazon offers a 30 day return policy on all items shipped from their warehouse.

Tips for Choosing the Best MIG Welder

What Will you be Welding? – You should know exactly what kind of work you’ll be doing regularly and then look for a welder with a bit more power than you’d typically need (see chart above.) You’ll feel pretty lousy if you buy a welder that’s under powered and wont give you a proper weld for the task at hand. More power costs a bit more but it’s better than having to buy another one after you realize the one you bought is under powered.

Budget – It’s easy to get carried away with more power and the latest features when choosing a welder but the price quickly adds up. Before you even think about buying a welder you should know how much you’re willing to spend and stick with that budget.

Brand – Besides the 3 best MIG welder brands – Hobart, Lincoln Electric and Miller – there are a few lesser known brands out there that are cheaper and produce outstanding quality welds. Some standouts include: Forney, GoPlus, Lotos, Everlast, AHP and Lotos.

Read Amazon Reviews – Amazon reviews are a tremendous resource for researching the pros and cons of the best MIG welder. You should always look for the welder with the most positive reviews. If it’s rated 4+ stars from hundreds of people it’s going to be a solid machine. But don’t just look at the positives, look at the negative reviews as well to see what are some of the common issues and if you can live with them.

Buy Used – Craigslist and Kijiji are goldmines for people who don’t mind buying used. People upgrade their welders and need to make room for their new rig so they put their old, perfectly good machine up for sale at awesome prices for a quick sale. There are obvious downsides to this like lack of warranty or shady sellers who sell you broken welders. This is the best option if budget is a major concern.
