Best MIG Welders For Beginners Reviewed

Gas Metal Arc Welding is a process of joining two metals together in a permanent bond. By heating the workpiece and the filler metals, the two melt together to form the weld. Metal Inert Gas welding, or MIG welding, is a subset of the GMAW process and is popular among beginners.

MIG welding is one of the basic welding types that can be picked up easily and mastered quickly. The equipment for MIG welding is relatively less expensive and generally more portable, making MIG welding a highly sought after trait for both career and hobby welders. This article will examine MIG welding and give you the best MIG welders for beginners.

Interested in getting into the craft of welding but unsure of where to begin? You’re looking in the right place. Finding the best welder for beginners can be tricky, as there are so many shapes and sizes out there that it can get a little overwhelming. There are right and wrong types of welders to choose when you are starting from the bottom, so doing your research into the proper option for a beginner is incredibly helpful.

Why Mig Welder Quality Matters

If you are new to this craft, you may be wondering why you should even be looking for the best MIG welder. After all, why invest in a potentially expensive object when you aren’t looking to do the craft professionally – won’t a cheap knockoff work?

The short answer: no.

The reason is because quality matters. A good MIG welder is important for a beginner to practice with. If you’re new to this practice and the first MIG you encounter is a poorly constructed knockoff brand that can barely complete a successful weld, you will probably be turned off to the craft completely.

When you are first learning how to do a MIG weld, you will learn about how the automatically fed spool creates an electrical current that melts and joins wire to the base. A quality MIG will ensure that this process is as simple and clean as possible, and also allow you to experiment with all kinds of metals regardless of how thin or thick the plates are.

Types of Welding: Which is Best for Beginners?

If you are a beginner or are recently showing interest in welding, you may not know that there are many different types of welding. Of all the welding styles and types, the four most common are MIG, TIG, Stick, and Flux Cored Arc welding. Let’s examine the four types and determine if MIG welding is the best for beginners.

MIG Welding

MIG welding is considered a beginners welding style or one for hobbyists. The constant-feed wire and smooth mix of gases allow for a weld that is quick to learn and simple to master. With a MIG welder, you can take on all types of metal, including steel, aluminum, stainless steel, and nickel.

There are instances when MIG welding won’t be ideal such as vertical and overhead welding. The temperatures are less forgiving, and the weld beads will run in these situations. However, because you can select from a variety of gasses, wire thicknesses, and metal types, MIG welding is extremely popular.

With the right equipment, MIG welding doesn’t have a lot of guesswork. You dial in the machine with metal type, thickness, and wire type. Once that is done, the equipment will run itself, providing you the optimal heat and wire-feed speed for the job at hand. Once you learn the different nozzle angles and speeds to use for the best welding bead, you have pretty much mastered MIG welding.

TIG Welding

Tungsten Inert Gas (TIG) welding is a welding process that is different than MIG welding. For starters, there isn’t a filler material or a line feed for TIG welding. Instead of using a different metal to heat and bond the workpieces together, TIG welding heats the two pieces of metal and melts them together.

TIG welding is a more precise welding practice and takes a well-trained operator. To decide which is better, TIG or MIG welding, for beginners, the answer will almost always fall to MIG welding.

The other significant difference is the ability of the welders. TIG welding is generally used for thinner metals and smaller welds. MIG welding can join thicker metals and make larger beads because of the filler material.

Stick Welding

Stick welding, also known as shielded metal arc welding (SMAW), is one of the oldest known methods of welding. It is also one of the most challenging welding types to master. Because the tip angles, electrical current, and setups must be exact, it can be complicated to learn, use, and master.

Stick welding uses a rod, much like the wire feed of a MIG welder. You will need to continually replace this rod as is it consumed. However, because of the versatility of stick welding, it is useful for many types of metal joining that other models cannot accomplish.

The most significant advantage of stick welding is that it can be done in adverse conditions such as rain or wind. To be proficient at stick welding though you must have a lot of experience and studies under your belt and is therefore not recommended for beginners.

Flux Cored Arc Welding

Flux Core welding (FCAW), is a faster alternative to MIG welding. It isn’t for beginners, though, as there are more advantages, but a higher learning curve involved. Flux core doesn’t use gas as MIG welders do. Instead, the constant-feed wire is coated in a flux that provides the anti-contamination that the MIG welder’s gas bubble does.

Like stick welding, flux core can be used in adverse conditions like the wind (not in the rain, though). The biggest advantage is that FCAW can join impure metals together without sacrificing composition.

Arc or TIG welding for beginners isn’t advised. Once you have mastered a more beginner-friendly method, like MIG welding, you can then move on to the more advanced techniques like stick, TIG, and flux-cored arc welding.

How MIG Welders Work

All MIG welders work in pretty much the same way. The gas creates a bubble to protect the metal from corrosion. The wire heats up and melts, creating a weld puddle and the transfer heat the workpiece metals, creating the welding bond. There are several types of MIG transfers, though, and this is where the difference comes in.

The most common form is known as a short circuit transfer. When the welding wire touches the workpiece metal, it heats up with low voltage and melts to create the puddle that binds the metals together. Carbon dioxide gas is used for the bubble. Because of the low voltage, single gas, and wire transfer, short circuit transfer is the least expensive and most comfortable to use.

Spray and pulsed spray transfers use a mix of CO2 and argon gases for the bubble, and the welding wire is melted and sprayed onto the working surfaces. The welds are generally cleaner, though they produce more spatter. Because of the use of higher voltage and argon gas, these spraying transfers are more expensive. For pulsed spray, the machine must be capable and generally costs a great deal more than other welding machines.

The globular transfer is the fourth standard transfer method. Here the welding wire is melted at the nozzle tip and is dripped onto the working surfaces. It uses argon gas and has a high spatter ratio. Because of the argon gas, the globular transfer method is usually more expensive than short circuit transfer.

Buying Your First MIG Welder (Buyers Guide)

Let’s take a look at the various considerations when deciding which welding machine to purchase. Depending on your specific needs, the following items will hold more or less weight in your final choice.

Simple Controls

For the beginner, having a machine that will automate the electrical output, wire feed and voltage is almost essential. There are plenty of machines that will handle various weld types, transfers, and voltage outputs. However, it is advised to find a machine with the most straightforward controls at least until you master the welding techniques and can move on to more complex welds.

Power Source

Using a welder with a simple and standard power input should be at the top of your list. Because most MIG welding is low voltage, you won't need higher input devices. A welder that has the standard outlet 110-120 volt input should suffice for over 90% of your welding jobs. You won’t have a need, in most cases, to spend more money on a multi-voltage input machine.

Consistent Welds/Quality

To get a consistent weld takes practice. However, having a high-quality welder will go a long way to making that happen sooner. Because you will most likely be using short circuit transfer to begin with, you should find a machine with a consistent voltage output to ensure the wire feed is heated and pushed at the same rate throughout the weld.

Welding Location

Where will you be setting up your workshop? If you cannot answer this question yet, you shouldn’t make a welder purchase. Each machine will vary in abilities in various conditions. If you are working out of your home as a hobby, for example, you will require a smaller, less commercial-grade welder than if you are working in an outdoor workshop. Knowing your primary usage location will be a significant factor in deciding which welder to purchase.

Feed Rate & Duty Cycle

Another feature that is often overlooked is the feed rate and duty cycle of the welder. You should determine the types of welding jobs you will undertake to get a machine that can keep up with you. The wire feed speed is one of the most critical settings. If your speed is too high, the gun will sputter and kick-back in your hand. At the right speed for the voltage, the wire will feed at a constant rate, and the gun won’t buck around.

The duty cycle is the rating at which the machine must rest per ten-minute periods. For example, if you have a duty cycle rating of 60%, then the machine can run for a solid six minutes before needing to rest. The rest time will take up the other 40%, or four minutes before you can rerun it. Longer weld times will require a higher duty cycle percentage.

Wire Size & Material Thickness

You won’t be able to set your feed speed without knowing the wire size (in millimeters or gauge). The size, or thickness, of your feed wire will determine how much voltage and speed the machine needs to operate under.

The thickness of your workpiece metals is also important to know. Thinner pieces need less wire and lower temperatures to prevent burn through. Thicker metals may need a stick weld or a TIG weld since MIG is designed for more lightweight applications.

Weight & Portability

If you are going to mount your welder and bring the work to it, the weight and portability may not matter to you as much. However, if you plan on throwing the welder in the back of the truck and taking it to the worksite, you may want to think about how much the unit weighs.

Some welders will top the scales at over 100 pounds, making them less than ideal to cart around on a whim. The more portable units weigh in at 50 pounds or less, making them better for moving or relocating as the need arises.

Thermal Overload Protection

MIG welders get hot. Constant use can cause overheating and the breakdown of components. Thermal overload protection prevents the machines from overheating and should be included in your final purchase decision. If the machine you are looking at doesn’t come with thermal overload protection, you may want to consider an alternative option.

Easy to Setup & Use

Beginners need to focus on their welding skills and be less concerned with the equipment setup. Spending a little more for a welder that has a minimal and straightforward setup process could be the leg up you need to get your projects going.

Using the machine should be a natural and comfortable process. Looking for a welder with simple controls, easily followed instructions and the ability for some leniency in the settings is well worth a slightly higher investment price.

Price & Warranty

If you aren’t yet making money from your welding skill, you might be on a tighter budget. Learning the craft while working with a less expensive machine is okay. You can turn your hobby into a paying career and upgrade to more advanced tools as you go along.

Besides the initial price, you should make sure that the welder comes with a warranty. Most of the welders on the list below come with a valuable warranty that you should take advantage of. Even if the warranty comes at an additional cost (most don’t), it is worth it to get the warranty or extend the current warranty. This will save you time, money, and frustration down the road.

Final Thoughts

Here is a helpful YouTube video from Lotos demonstrating the MIG140:

Setting Up a Welding Workshop

A welding workshop is crucial for hobbyist and career welders. When safety is paramount, you need to be able to control the environment as much as possible. TIG welding needs to be done indoors, as windy conditions are not suitable for the gas bubbles. You also need to be able to control the temperature as much as possible.

To set up a shop, you will need a good size room that allows you to house all of your equipment. Use a worktable that will suit your needs plus have enough room to maneuver around all sides. You also need proper ventilation, so make sure you have fans, windows, and air control devices such as air conditioners. On top of all of that, you should have the following equipment.

  • Worktable made of metal with a 40-foot diameter clearance (to avoid fires from slag and sparks).
  • MIG welder with electrical supply and gas tanks (appropriately stored to avoid damage or safety issues).
  • Propane heating torch to properly heat cold metal before welding.
  • Safety screens.
  • Welding fume extractor, or other high-volume air ventilation devices.
  • Concrete flooring and brick or cinder-block walls (or metal coverings to protect wooden walls from fire hazards).
  • Welding accessories stored within easy reach of the workstation. (See below for details).

Using MIG Welders for Beginners

Beginners may not know how to set up a MIG welder properly. The process is straightforward and relatively simple. However, there are often things that overlooked by both beginners and journeymen alike. A refresher is never a bad idea, so we have compiled this list on the proper MIG welder setup.

  • Purchase, store, and use the proper personal protective equipment (PPE). This will include a welding apron, gloves, #10 (or darker) shield mask, long pants, work boots, ventilation mask, etc.
  • Have safety equipment nearby in case of fire. You should have a minimum of a CO2 fire extinguisher and a large bucket of sand to douse any flames quickly.
  • Prep the welding surface and work area by cleaning the metals and removing any flammable materials (at least 25 feet around the area, 40 feet is better as slag and sparks can travel far).
  • Select the proper wire for the job by matching metals, thickness, and type. Spool the wire following the welder's instructions and avoid wire slack.
  • If the option is available, set the polarity of the welder to DCEP (reverse) polarity.
  • Clamp the welder to the grounding bolt or worktable and test the spooler by feeding the wire through the welding nozzle.
  • Use the right shielding gas for the job at hand.
  • Finally, test the welder setup on a scrap piece of metal to ensure the wire feeds properly, the speed is accurate, and the weld bead is smooth and solid.

Safety Tips While MIG Welding

Welding produces high heat, sparks, slag and spatters of molten metal. Fire and personal safety risks are imminent, yet avoidable. Taking the proper precautions before starting work will go a long way to avoiding injury, fire, equipment damage, or worse.

  • Always wear proper-fitting PPE.
  • Have a CO2 fire extinguisher and sand bucket nearby.
  • Properly clean the work station and workpiece metals and ensure all grease, gunk, build-up, and water is removed.
  • Test the equipment on scrap metal before working on the final project pieces.
  • Know the duty cycle of the welder you are using and do not overload the equipment.
  • Ensure your feed wire is taught, under the correct tension and is clean from grease, paint, or water.
  • Stay alert to your surrounding area and other people nearby.

MIG Welders: Common Issues & Fixes

Below are some of the most common issues associated with MIG welders, their output, and the weld beads in general. If you experience any of these issues, the following list should help you diagnose the problem.


Affected Area


Convex Bead

Weld bead or base metal

Heat input is too low, raise the input temperature.

Flat Bead

Weld bead

You are most likely pushing the gun instead of pulling. Pull the gun down and use a 5 to 10-degree angle.

Excess Penetration

Base metal

Input temperature is too high. Lower the temperature.

Welding Spatter

Bead and workpiece metals

Spatter is caused by high wire speed feeding and high voltage. Check your settings and lower the feed speed or voltage as necessary.

Wire Won’t Feed

Welding gun or welder

There is a jam or “birdnesting” with the wire spool. Check nozzle tension and open the welder to check the spool. Re-roll the wire and apply proper tension as needed.

Porous Bead

Weld bead

The most common issue with a porous bead is metal contamination. Ensure the workpiece metals are clean, dry and free of contaminates

Welding Accessories

Besides the welder, gas tanks, nozzle, and wire, you will need to have some welding accessories in your shop or work area. Being overly prepared is better than having to stop in the middle of a project because you don’t have the right tool to complete the job. Let’s take a look at other items you will need.

Welding PPE

The idea behind personal protection equipment, or PPE, is to prevent bodily harm while welding. Your entire skin surface should be covered, including hands, feet, arms legs, and torso. When shopping for PPE, you should make sure the equipment is rated for welding or at a minimum for extreme heat.

A welding helmet will cover your head, and along with a #10 or darker eye mask. You will prevent sparks from igniting your hair, landing on your face and neck and prevent arc eye. Welding gloves avoid burns, and a welding apron will protect your clothing a torso.

Other items to consider are a good pair of work boots, long pants designed for working conditions, and long sleeve shirt to protect your upper arms and shoulders. Even a bandana to prevent sweat from getting in your eyes is a good idea.

Tools and Miscellaneous Equipment

Once the PPE is taken care of, you will need other items in your shop to help with the welding process. Chipping hammers and wire brushes are used to clean up the workpiece metals, removing burrs, rust, paint, and other contaminants before welding.

Having a variety of gas nozzles and contact tips will ensure you are ready to weld whatever metal comes your way. A good mix will enable you to perform a weld on all metal types regardless of joining or hole repair size.

Finally, a good set of angle grinders will clean up your beads and smooth out any burs or globs created. The finished metal will be ready for sanding, painting, or application when you are finished with your portion of the job.

Frequently Asked Questions

Let us answer some of the most common questions about MIG welding and welding in general.

How hot is MIG welding?

MIG welding requires the base metal to melt to bind the workpiece metals. The temperature needed for this varies, and MIG welding can range from 3,000 to 20,000 degrees Celsius (5,500 to 36,000 degrees Fahrenheit).

What is arc eye in welding?

Arc eye is when the cornea of your eye is burned due to exposure of UV light. Sometimes called welder’s eye or a flash burn, arc eye can lead to permanent blindness.

How to know when to use MIG vs. TIG welding?

Besides experience and metal type, the primary difference between MIG and TIG welding comes down to the thickness of the metals being joined. TIG welding is superior with thinner metals, while MIG welding is ideal for thicker pieces.

What size MIG welder do I need?

Unfortunately, there isn’t a one-size-fits-all approach to MIG welders. The best option, though, is to find a welder that can handle various sizes of feed wire, and produce a wide range of output amps. Single-pass phases can vary from 20 amps to 300 amps (or more). Buying a welder for general application use is almost impossible. However, with the right set up, choice of nozzles and gases, a welder that offers 30 to 150 amps output should cover most of your beginner needs.

How much does a good MIG welder cost?

The idea of a general price point for a good MIG welder is subjective. What defines a good welder and how much can you spend. In most cases the “you get what you pay for” adage fits, but you can find great deals during Amazon Black Friday MIG Welder specials. The accepted range for beginner MIG welders falls between $400 and $1,500.

How do you MIG weld without gas? Is that possible?

Technically, gasless MIG welding is impossible. The nature of a MIG weld uses gas to create a protective bubble around the weld point. When someone speaks of gasless MIG welding, they are generally using a flux core metal tube in a process called self-shielding.

What are the most popular brands of MIG Welders that are currently in the market?

Currently, the top three brands of MIG welders on the market are Miller, Lincoln, and Hobart. The brands are reliable, affordable, and durable. Many master welders still have their first Miller or Hobart welders that were purchased when they were still beginners.

Is stick welding stronger than MIG welding?

The short answer is no; stick welding is not stronger than MIG welding. However, it all depends on your stick or feed wire being used and the depth of the weld. Stick welding can penetrate deeper than wire fed MIG welding, which can produce a stronger bond. On a level playing field though, using the same tensile stick or wire will produce an equally strong weld.


Beginner welders aren’t limited in their welding choices anymore. You can learn to MIG weld in your spare time without having to go to a technical school. With welders becoming more affordable and more capable, the hobbyist and beginner MIG welder will be up to par quickly.

For the novice looking to hone the craft of welding and to learn on an affordable and highly-capable machine, the Miller Electric Millermatic 211 is the best option. It will not only help you learn how to weld correctly but is versatile and durable enough to last you for years to come. The initial investment will pay for itself, allowing you to maintain the same welder as you progress through the various welding skill levels.
