Things to Look for When Buying the MIG Welder

Things to Look for When Buying the MIG Welder

Now that you have seen our featured products, you should have a decent idea about the quality you can expect at this price range.

We picked each of the units after extensive research and considering some of its crucial features to ensure it comes with everything a welder might need.

If you want to be fully sure of your investment, you cannot overlook these features. Unless you know exactly which model you want to buy, you must weigh your options critically to assess which one of the products will give you the best performance for the money you spend.

So, without further ado, here are a few things you want to consider when buying a MIG welder under 500 dollars.

Input Power

The first thing you must address when buying your MIG welder is obviously the input voltage. A MIG welder operates at either 110V or 220V of power. The welding capacity of the unit varies depending on its operating voltage.

With 110V, you will get a bit less power. However, most wall sockets in a domestic environment are rated at 110V.So, you will be easily able to find a viable power source for your machine.

On the other hand, a 220V unit might come with more juice in the tank, but unless you are a trade professional, you might not benefit from it too much. Furthermore, you have to convert a wall socket in your workshop into 220V.

Another option you have in selecting a MIG welder is dual-voltage. This type of unit can switch between 110V and 220V, eliminating some of the hassles on your part. However, they can get quite expensive.


This is what helps you measure the power output of a welder. A lot of other factors, such as its duty cycle, how thick of a material it can cut, depend on the amps value of the unit.

So, you must check the total amperage it can give and the adjustability range you get with it before committing to a particular model.

At 500 dollars budget, you have a lot of different options. The best way to proceed is to understand how much amps you need for the type of work you do on a regular basis.

If you plan on doing occasional house repairs, you do not need a high amp unit. But for a professional, the amperage requirement is definitely higher.

Material Selection

Typically, the type of material a MIG welder can work with varies from one model to another. A few materials that are common across the board are mild steel, aluminum, stainless steel, etc.

These are the common material that you would work with as a hobbyist or a DIY enthusiast.
However, there are a few heavy-duty welders you can find that can work with alloys, iron, and even cast iron.

For someone who frequently works with these materials out of pleasure or business, a heavy-duty MIG welder is a necessity. Always weigh your requirements with your options before investing in a product.

Material Thickness

As we mentioned before, the thickness of the material you can work with depends on the amperage of the material.

So, you need to determine what type of work you will be doing. Another thing to keep in mind about MIG welders is that they are typically used for a thinner gauge of metals.

When choosing your welder, make sure you look at how thick of a material it can cut through. If you are a power user, make sure you invest in a unit that allows you to work with materials of up to ½ inch thickness. For domestic use, 18 gauge or ¾ inches of materials should be sufficient.

Duty Cycle

Duty Cycle

To put things simply, the duty cycle is the efficiency of the machine that you want to buy. The value is typically shown as a certain percentage of duty cycle running at a certain amount of amps.

But a beginner might not understand what it fully means, which in turn can lead to bad decisions.

For example, if a unit has a duty cycle of 20% at 50 amps, then what that means is that for an interval of 10 minutes, it can run at 50 amps for two minutes.

After that, you need to shut down and let it cool off for the rest of the eight minutes before you can start using it again.

However, when you reduce the amperage, which you can do typically using a dial on the machine, you can get a longer usage time with the machine.

But it is worth looking for a unit that comes with a higher duty cycle. It means you will get a better uptime without having to push the unit above its limits.

Weight and Portability

Another element you want to check when buying a MIG welder is its weight. The weight of the unit directly affects its portability.

So, if you are someone who needs to move around with the MIG welder, it might be worth investing in a lightweight model to save yourself from a lot of hassle.

Most MIG welders weigh somewhere in the neighborhood of 50 pounds. However, these days some modern models come at a much lighter design.

Another element you could look for is the inclusion of carrying handles at the top. That way, you will have an easier time carrying it around from one place to another.

Safety Features

Apart from the power and efficiency features, you also want the MIG welder to come with a few basic safety features.

These options will ensure that your unit will save itself if something goes wrong in terms of power supply or anything else. Without a few key safety features, the durability of the unit is compromised.

One such feature is thermal overload protection. It ensures that the unit does not overload, and when it detects abnormal amounts of power, it shuts itself down to protect the unit.

There are a few other different cooling solutions that come with different units. It is always worth checking out what safety options you get with your MIG welder.

Frequently Asked Questions

How do I maintain my MIG welder?

One of the best things about a MIG welder is, although it requires a bit of maintenance, the process of taking care of it is simple and straightforward.
