Benefits of Dual Voltage MIG Welder

Benefits of Dual Voltage MIG Welder

Even though these versions of the tool did not pop out recently, the market is still oversaturated with the single voltage ones. The reason behind this would be that not many are aware of the benefits that they are capable of bringing to the table. That being said, the main benefits that you are likely to enjoy with one of these are:


In theory, these units are capable of working in two different voltages. And for you to work with two individual voltage flows, there will be no added expense of buying two different machines with a particular voltage rating. This feature is the main selling point of these devices.

Basically, with one of these, you can work with two different voltage inputs. Whether you are working in a 120 volts area or a 240 volts one, one of these puppies should be more than enough.


Power and Efficiency

By design, most of these devices should be more powerful than the regular single voltage ones. They should have a theoretically higher amount of efficiency as well. And for excelling in both of these factors, these are not only ideal for the professionals but also for hobbyists and the people operating small-scale projects.


What to Look for Before Buying?

Features of Dual Voltage MIG Welder

Going through the reviews is not going to be enough if you want to get your hands on something that is actually worth buying. For that, you must keep some of the crucial points in mind. And the points that we are basically referring to here are as stated:

Build Quality

Before anything else, you should consider the build quality. This one is not an average tool that you would take to a construction site. It is meant for heavy-duty tasks in heavy-duty work environments. So, the build quality should be adequate to withstand the pressure of such works and workspaces.

For that reason, you should check the quality of the materials. Usually, the ones that use high-quality materials for the overall construction are the ones that have a praiseworthy build quality. Those have a high level of durability as well. You would be able to expect to get extended use out of them.



Considering the use case of these tools, you need to move them around from one place to another. And when it comes to carrying anything, the more compact the unit, the easier it becomes. Considering that, we would recommend you to pick up the reasonably small and compact ones. Those will be easy to carry.



The weight is another crucial factor that you should consider when you are purchasing one of these. This factor is also going to play a significant role in making it easier for you to carry it around. Also, the lighter ones are easy to move around as well. For that reason, you should pick the ones that are lightweight.



As these are dual voltage capable, the power is something that you will not have to worry about that much. These are going to be highly capable. However, the thing that you need to check is the welding capacity. Some of these will be capable of working with materials that are 3/8 inches thick.

On the other hand, there will be many that can work with ½ inches thick materials. Depending on your work case and the type of material you mostly handle, you should choose one. However, to be on the safe side, we suggest picking the ones that are capable of working with reasonably thick materials.


Display or Meter

One of the important factors that you must consider when buying one of these is the meter or the display on the front. Make sure that it can offer you all the required information. Without having proper knowledge about the gas level, line speed, and other criteria, it would be impossible for you to maneuver it properly.


Protection Features

Another thing that you should check is whether the unit that you are picking up has safety features or not. We would highly suggest not picking the ones that do not have any protection features. Those will not only be unsafe, but the chances of them being capable of offering consistent performance will also be pretty low too.


How MIG Differs from Other Welding Methods?

Dual Voltage MIG Welder

Both the metal inert gas and the tungsten inert gas weldings belong to the arc welding family. That means the operational process for both of these will be pretty much the same. However, there will be scenarios in which one will shine over the other one.

Highly Forgiving

To start with, MIG is a bit forgiving than the other welding methods. This one continuously feeds metal wire. And for the continuous flow, you can rely on the wire or the filler agent to be there when you are working on any intricate projects.

On the other hand, the other methods do not always have a filler agent flowing. For that reason, when you are handling those, you need to be extremely accurate, or else the connections you will make will not be that secure. Considering that, MIG is more catered towards beginners.


Can Make Strong Bonds

The MIG units are known to be capable of making a stronger hold. Because of having that capability, they can work with thicker items properly. The bond that you are going to get will be much stronger, and you can rely on it fully to hold against the test of time.

On that note, the metal filler that is used for the MIG is highly capable of making a strong bond between thick materials. So even if you are working with a higher gauge material, the possibility of the bond breaking will be pretty low.


Spatter Control

One of the factors that the MIG does not shine that much is in controlling the spatter. On that note, the spatter does not weaken the bond by any means, but it does make the workpiece look a bit unsightly. Nevertheless, if you were shooting for something that can offer you smooth finishes, you should choose the TIG.


Frequently Asked Questions

1. What is the actual benefit of having a dual voltage tool?

As you can guess from reading the label, these tools are going to capable of working in two different voltage levels. That means if you stumble into a scenario where you require exceptionally high voltage or extremely low voltage, there will be no need to switch your tool with something new.


2. What types of steel can the MIG welder weld?

MIG welders are known for being capable of working with a vast number of metals. You can work with stainless steel, aluminum, copper, carbon steel, silicon bronze, and nickels. Aside from all of these common metals, you can also use them to work with different types of alloys.


3. Is the bond created by MIG stronger than TIG?

Yes, the bond that the MIG can create is considerably stronger than the TIG. The reason behind the strong bond is the continuous flow capability that the tool has. As a result, if you were planning to bond two thick metal workpieces together, you should pick the MIG over the TIG.


4. Does MIG create more spatter than TIG?

Compared to TIG, MIG tends to produce a bit more spatter when it is used to bond metals. However, the spatter does not weaken the strength of the bond by any means. All it does is ruin the overall outlooks of the workpiece. Nevertheless, if smooth finishes are what you look for, you need to consider TIG.


5. Do MIG welders come with any sort of built-in protection?

You will find plenty of these welders having different sort of built-in protection circuits. Starting from temperature control to overload, some will have them all. However, there will be a few that will not have any sort of protection. Those are the ones that you would want to stay clear of.


Final Words

Now that you have a proper idea regarding the best dual voltage MIG welder that various brands are offering in the market, hopefully, it will not be a difficult task for you to choose one. However, if you want the best possible results, we recommend checking the Weldpro 200 Amp Inverter before any other ones.
