Among various welding methods, MIG welding has established itself as the most popular and widely used method. Time efficiency, ease of use, and versatility make MIG welding superior to any other technique.

Now, the market is full of options due to this popularity, and often it gets overwhelming for beginners to choose the right machine.

So, today, we have rounded up this list of some market best professional Mig welders with in-depth reviews.

So, let’s have a look.

First let’s describe the

Advantages and Disadvantages Of MIG Welding

There are several arc welding methods, and MIG welding is considered the easiest. This technique has several benefits that make it so popular among welders.

But at the same time, there are some limitations that you need to consider before you choose MIG welding. The list of advantages and disadvantages below will help you make the decision.

Advantages of MIG welding

  • The first advantage that will come to a professional welder’s mind is the speed of MIG welding. If you compare MIG welding with other methods (stick, tig, flux core etc.) it will win most of the time because the electrode is continuously fed. Minimum slag removal time also helps with the time efficiency of MIG welding.
  • MIG welding is very easy to perform, which is a big plus point for novice welders. In addition, several steps of the MIG welding are automatic, and the one-handed torch makes the usage super easy. That’s why MIG welding is considered the best method for beginner welders.
  • Versatile welding material is another advantage we need to mention. The penetration is already great for MIG welding. You’ll get exceptional welding results with good penetration, no matter the material. This deep penetration also ensures that the welding goes perfectly.
  • MIG weld is well-known for its clean welding results. There is no flux in MIG welding to contaminate your welding, thanks to the shielding gas. As a result, there are minimum slugs to clean. This clean welding also lets you weld faster instead of cleaning the slug.
  • If you have a small welding project, this might not benefit you. But for longer welding projects, the long-pass welding capability of MIG welding can be a great help. With other welding techniques, you might need to stop and start often, which is not the case for MIG welding.
  • MIG welding is all about efficiency, and it’s clear from the minimum loss of electrode wire and alloying element. The credit again goes to the shielding gas, which protects the arc, and there is almost no loss of alloying element as the arc forms.

Disadvantages of MIG welding

  • The higher cost is the biggest disadvantage of MIG welding. Let us explain why. MIG welding equipment is already pretty expensive, increasing the overall cost for starters. Next up, there is other additional stuff you’ll need shielding gas, extra tips, and electrodes that add up to the cost.
  • MIG welding is not a great option if you plan to weld outside. MIG welding uses gas most of the time, and the wind outside can ruin that gas shield. Therefore, the quality of the welding can be affected. Therefore, it’s best if you don’t choose MIG welding for outdoor welding.
  • Deeper penetration can be a potential issue for MIG welding. In demanding welding jobs, you might need to weld thicker pieces of welding materials. On the other hand, MIG welding is more suitable for delicate welding with thinner materials.
  • The portability can be an issue since many additional accessories are needed to perform MIG welding. For example, you have to carry welding gas, a roll of wire, and the welder itself is pretty heavy to carry around. So, MIG welding might not be a good option if your job requires portability.
  • Burh through and undercutting is very common MIG welding. However, since MIG welding has a constant voltage output, ting welding materials often get burnt if you are not careful. Also, the gas often fails to protect the tungsten, resulting in reduced cross-section thickness.
  • MIG welding takes a longer preparation time. Apart from compiling all the accessories and equipment, you also need to prepare the material by cleaning the rust and dirt, which can be time-consuming. Also check out can you weld rust metal here.

MIG welding process (step by step)

As I mentioned earlier, MIG welding is super easy to perform with the right technique. If you are new to welding and wondering how to MIG weld, the step-by-step guide below will help you.

  • Step 1: The first step to starting MIG welding is to wear safety gear. Every type of danger, including heat, electricity, and bright light, is involved in MIG welding. Without proper gloves, eye gear, and other necessary safety gear, MIG welding can be dangerous.
  • Step 2: After ensuring safety, it’s time to calibrate the MIG welder. If the machine is new, take some time to know the welder thoroughly. Then according to the project, set up different perimeters according to your project.
  • Step 3: MIG welding needs shielding gas, so make sure the regulator and gas cylinder work perfectly. The regulator has an adjustment screw that adjusts the gas pressure. Keep that loose so that rotating it is easier when necessary.
  • Step 4: Before starting, some preparation is necessary for optimum welding results. Weld in a place with enough space and air nearby to avoid the toxic fumes. Preparing the welding materials I also necessary. Make sure there is no rust or blemishes on the surface.
  • Step 5: At this point, you are ready to turn the MIG welder on. So, use the power cord and do it. Most welders have the wire feed speed and voltage setting at the front. Use those controls and set the necessary value. The welder can melt through the material if the value is set high. So, it’s always best to start low.
  • Step 6: Just checking whether the feed wire inside the gun is not enough; also make sure the amount of wire is sufficient. If the wire is too long, cut it to the right size. Press the trigger once to ensure there is no problem, and the wire is through.
  • Step 7: Start welding by lowering your helmet or facemask. You can use the push or pull technique according to your comfortability. It’s usually best to start from the top of the weld and then end at the bottom. After welding is finished, set the wire feed to the lowest setting.
  • Step 8: You need to prepare to turn off the welder in this step. Start by closing the cylinder valve and bleeding the regulator to zero. After all, these are done, turn off the welder and unplug it from the power socket.

Buying Guide

MIG welders are very complex tools; there is no doubt about it. Moreover, different models often come with different features and controls, making sit confusing for users to choose the right unit.

Below, we have compiled a list of factors you can use to find the best welder for professional MIG.

Power Supply & Power Cord

This is a basic consideration to make since you won’t be able to run the MIG welder properly without a proper power supply. Moreover, it can result in electric accidents too. Different welders utilize different voltages according to their purpose.

So make sure the welder you choose can run with the power socket at your house or workplace. Also, make sure the power cord is long enough to handle your need. Otherwise, it can limit your welding experience.

Live Torches

Torch plays the most crucial role in MIG welding as it does the main job of welding. Now, there are two types of torches available in MIG welding. Either you can use a live torch or opt for a trigger-mounted torch.

  • Save

On the trigger-mounted units, you have the option to pull the trigger to start the weld. But on the other hand, live torches always generate uncomfortable heat and sparks, which can be harmful to the user’s eye.

So the best thing to do here is to avoid live torches for more control.

Duty Cycle

The duty cycle means the duration of the weld at one go. So, if your welding projects need you to keep welding continuously, you need a MIG welder with a higher duty cycle. The duty cycle is normally shown in percentage of 10 minutes.

So, if the duty cycle is 50%, you can operate the welder for 5 minutes straight, and then it’ll need a cool-down time of 5 minutes.

Gas Cylinder

It’s not necessary that MIG welding will always require gas to operate. For example, if you are welding outdoors, you don’t need gas for the optimum welding results. However, things changes if you are welding indoors, where the look of the weld matters.

  • Save

So make sure the MIG welder you are buying has a gas cylinder.

Also Check


Regulators, also known as gas flow meters, are important to overlook the cylinder’s gas flow and control it. Though the welder has a recommended gas flow, you’ll need a regulator for accurate numbers. Different gases have different regulators, so make sure you use the correct regulator according to the gas.

Drive rolls

The importance of drive roll is somewhat the same as contact tip. For optimum welding, you have to keep the drive roll clean. Welders are often sued outside in harsh conditions.

As the wire passes through the drive roll to feed, it often has dust buildup. You can clean the buildup by using a vacuum.

Contact tips

No one wants to weld full of spatter. For that, a clean contact tip plays a very important role. If the contact tip is not enough, you won’t achieve the desired welding result, and it can cause porosity.

Moreover, there is a chance of reducing the gas flow due to the spattered contact tip. So make sure the contact tips are clean. If you want to keep the contact tip clean, using nozzle dip is a great idea.

Feed Speed

Feed speed is just what the name implies; it indicates how fast the welder can feed the wire through the torch. This speed is important because you don’t want to mess up your welding with too much sputter.

For best results, puck a MIG welder that offers both fast and slow feeding with variable speed control.

Safety features of MIG welding

As I mentioned earlier, MIG welding involves every kind of risk. So, you need to consider the safety features carefully to avoid any accident. A safety feature that you must look for is thermal overload protection.

MIG welder often gets overheated, and the protection can help you avoid damage by turning it off. You should also check out the cooling capacity and how the fan performs. An effective fan can easily prevent thermal overload from happening. 

Correct amperage for MIG welding

Again, there is no correct amperage for MIG welding. The question here should be more like this, what’s the correct amperage for a certain thickness and material.

In MIG welding, the general rule of thumb is that every 1 amp of power will weld 0.001 inches of steel. You can have an estimate from there.

How thick can a 90 & 150 amp MIG welder weld?

The amperage mostly decides how thick a MIG welder can weld. Among the wide range of MIG welders, 90 and 150 amp are two of the most common ones. While 90 amps can weld from 1/8 inch to 3/16 inch, the 150 amp welders can do almost double that, depending on the material.

Of course, you can also weld thicker, but that’ll require more than a single pass.

How many amps is a good MIG welder?

There is no straight answer to this question since it’s completely subjective and depends on many factors. A MIG welder can easily go from 60 to 400 amps, and which one will be good for you depends on the material and thickness.

The rule is simple the thicker and stronger the material, the more amperage you’ll need.

FAQs (Frequently Asked Questions)

Q: What’s better, Hobart or Lincoln?

A: Both Hobart and Lincoln are established players in MIG welding. If we take their 140 amp MIG welder, there are many similarities in the feature set. Which one will be better for you depends on your preference.
While Lincoln 140 is better at penetration, Lincoln 140 offers a wider amperage control. Depending on which advantage you prefer, you should choose the better option.

Q: What is better, Lincoln or Miller?

A: Both Lincoln and Miller are equally popular in the welding industry. So, picking a winner might not be an easy job. If you are into MIG welding, Miller seems like the better choice overall. On the other hand, Lincoln is a suitable option for stick welding.
From the cost point of view, Miller is a bit more expensive than Lincoln too. Lastly, Lincoln seems to have the leading in terms of build quality and ease of use. All their welders are made for user-friendliness and longevity.

Last Words

That’s a wrap for today. I hope my review on professional MiG Welders comes in handy to make a decision. See, there are a lot of factors to consider while purchasing a MIG welder, and everyone prioritizes different factors.

So, all you have to do is get your priorities straight and pick the welder most suitable for yourself.
