Advantages Of MIG Welding

Most experienced users opt for MIG welding over TIG and Stick welding because they can apply it to all kinds of materials including thick carbon steel, aluminum, and alloy. Additionally, the self-shielding does not cost too much, and the machine is quite simple to use. Newbies can also benefit from the auto-feed wire that produces a comfortable and smooth weld.

Unlike other models, you don't have to worry about changing the brush and rods too frequently to remove the slag, which helps you save plenty of time that you can use for other more important tasks to boost productivity.

Also, while TIG welding may not be suitable for beginners, MIG welding can be learned by practically anybody with just a few days of practice, which is the perfect machine for users who are in search of a model for home use.

Reasons To Invest In An MIG Welder

Wondering why you should set all of your savings aside to buy an MIG welder? Here are some benefits of MIG welding:

Higher Productivity

With MIG welding, you don't have to worry about constantly changing chips and rods, which saves more time, allowing you to spend all your time productivity.

Simple To Learn

Another advantage of using an MIG welder is its simplicity. If you are a beginner, you can take up basic training on how to use the machine more efficiently. Pay particular attention to how to clean the weld. TIG welding is a more complicated process and is not suitable for beginners who want to work on home projects.

Smooth Welds

Users can rest assured they will achieve smooth welds using the MIG welders. The simple machine offers superior control and helps amateurs make the perfect weld. MIG provides better weld pool visibility. Add this to the simplicity of the process and better control provided by the auto-feed wire, and MIG makes it simple to produce a great looking weld.


MIG welding incorporates the use of shielding gas that protects the arc, which guarantees there is little loss of alloying elements since the material transfers along the arc. With only a few minutes of clean up, the MIG welder will be all set for the next round. Also, clean up does not require much effort so you can utilize your time more productively.


Compared to other types of welding equipment, the MIG welder is incredibly versatile and is suitable for a variety of alloys and metals. Apart from home welding projects, some industries employ MIG welders. Some common metals that you can work on with this machine include stainless steel, magnesium, nickel, copper and lots more.

Factors To Consider When Purchasing The Best MIG Welder

Here are a couple of factors you should keep in mind while investing in the best MIG welder:

Input Power

MIG welders typically run on 220 V or 110 V while some manufacturers offer units with dual voltage for increased flexibility. Invest in a machine with a higher voltage if you want to perform heavy-duty tasks.

A lower voltage machine is a good option if you want to work on projects around the house and only use thin metal. A high-powered 220V machine is a good choice if you want to weld thicker sheets.

We suggest you play it safe and purchase a welder with a multi-voltage option, which will allow you to adjust the power setting according to your project. Some high-end models automatically alter the voltage according to your needs.

Duty Cycle

10-minute increments define the duty cycle. The span of time you can run the welder during these ten minutes is known as the duty cycle. If the MIG welder you have purchase has a duty cycle of 20%, it means you can weld for 2 minutes out of 10 before the machine has to rest. A higher duty cycle ensures you can get more work done in a short amount of time.


MIG welders offer stress-free welding. Carrying around a heavy machine is not always the most practical choice and can also lead to storage issues in the long run.

Portable MIG welder.

Newbies are especially known to face problems in running the bead on the right welding zone if the machine is too heavy. However, don't compromise on the performance of the device since it is one of the most important factors when investing in an MIG welder.

Heat Overload Protection

You should not overlook this feature when investing in an MIG welder because it guarantees the safety of your home and your workplace. This function automatically shuts off the machine when it's overheating, therefore reducing the risks of accidents and ensuring the longevity of the machine.

If you value the safety of people around you, invest in a welder that has a thermal overload shutoff button.

Material Thickness

The wire size and material thickness are one of the most important factors to consider when investing in an MIG Welder. Fortunately, the material thickness is not much of a problem since most welders allow users to control the amount of power you need thanks to the digital display found in most units.

However, it is crucial you inspect the maximum and minimum thickness of the metal, which will ensure you don't overload the machine or end up breaking it.

If you are a professional welder, you will benefit from a product that offers an auto-set option. This option allows you to dial the thickness of the material and the machine will automatically alter its settings according to your requirements.

Additional Parts

Many manufacturers offer bundle deals so look out for spare parts to accessorize your welder. Don't forget to buy a helmet or any other kind of safety equipment.

Price And Warranty

Buyers need to ensure the particular MIG welder falls in their budget and has an impressive warranty. A guarantee depicts how certain a brand is about their product and shows how committed they are to their customers. Buying a welder may look like a challenging task, but if you follow these instructions, you will have no trouble at all in selecting the best model.

Maintenance Tips For Your MIG Welder

Proper maintenance is necessary if you want to prolong the life of your MIG welder.

Regular touch-ups can prevent the machine from overheating and is crucial for the longevity of the machine.

Replacement parts for MIG welder.

However, it is essential you read the owner's manual first as the type of maintenance can vary from unit to unit. Here are a few basic guidelines you should follow:

Follow The Specifications

The best way to prolong the life of your welding equipment is to use it for its intended purpose. Pay close attention to the duty cycle of the welder as it will keep you from pushing the machine beyond its limits.

You can prevent damage to your machine by selecting projects that will not push the machine far beyond is capabilities and limits. Ensure you purchase the right model according to your projects.

Regular Maintenance

Professional welders know the importance of taking the covers off their MIG welders and blowing compressed air into the unit, which is especially important if you use the same space for woodwork as it would remove all the dirt and debris from the mechanical parts. It also a good idea you cover the machine when it is not in use to prevent it from getting worn out.

For future use, it is recommended you perform woodworking tasks in a separate location away from the welder since sawdust can find its way near the machine and create a spark, resulting in a flame, which is also important for the long-term performance of your machine.

Regularly Cleaning The Machine

After weeks of use, ensure your welding equipment is clean and ready for use. Follow the manufacturer’s guidelines for cleaning the equipment.

Maintain The Piece Of Equipment Regularly

To ensure your welding equipment is in perfect running condition, schedule a regular maintenance. Some shops offer weekly, monthly or yearly services to ensure the machine runs as good as new even after several years of use.

Regular check-ups eliminate the risk of the machine burning or breaking down unexpectedly. However, it is essential you set up routine maintenance according to your usage.

Replace Worn-out Parts

To ensure the machine is in perfect working condition, replace worn out parts as soon as you suspect something's wrong. Certain components of the MIG welder, such as the wire feeder and the brushes may have to be replaced from time to time depending on how often you use the machine. Replace the liner to ensure the wire feeding works smoothly.
