MIG welding can be costly, especially when you have to purchase a gas cylinder and other accompanying accessories. But does it have to be? The truth is MIG welding can still be achieved even without a gas cylinder.
This is what is called gasless MIG welding. Gasless MIG welding involves the use of a self-shielding wire. The latter wire comes with a flux-core coating that releases a shielding gas when burnt.
Now that we know a little bit about what gasless MIG welding is, the next question is, which is the best gasless MIG welder? We have compiled a list of four gasless MIG welders that you should consider.
At the top of the list is the SUNGOLDPOWER welder. This is the most versatile and powerful on the list. With its current range, it can weld thicker sheets of metal.
In second place is the YESWELDER Digital MIG-205DS MIG Welder, which also delivers 205 amps of max power output. All the same, all the welders on the list are worth the money.

What is gasless MIG welding?
A gasless MIG welder is a type of MIG welding that does not require the use of a separate gas tank to supply shielding gas. In a no gas MIG welder, the shielding gas is generated when the electrode burns and releases a gas.
The gasless MIG wire has a flux core coating that releases a shielding gas when burnt.
Advantages of gasless MIG welding
- Gasless MIG welders are lightweight and convenient to use since you do not need a separate gas tank to operate them.
- Unlike gas MIG welding, gasless MIG welding can be done on dirty or rusted surfaces.
- Gasless MIG welding can be done outdoors as opposed to gas MIG welding that can only be done indoors.
- Generally, it is easier to work with gasless mig welders than with gas MIG welders.
- Gasless MIG welding has greater deposition efficiency, which translates to faster welding.
Disadvantages of gasless MIG welding
- Overhead or vertical welding with a gasless MIG welder is not all that easy.
- Has a higher likelihood of producing toxic fumes that contain Argon, nitrogen, carbon monoxide, carbon dioxide, and hydrogen fluoride
Gas vs. gasless MIG welding
So should you go for gasless or gas MIG welding? This is an important question, whose answer depends on several things. That being said, let’s look at how these two MIG welding processes compare and contrast.
Ease of use
With gas MIG welding, you have to clean the surface of all and any surface contaminants. With gasless MIG welding, this is not a necessity. As such, gasless MIG welding is more suited for industrial projects. Gas MIG welding is better for fabrication purposes, where the aesthetics of the finished product matter.
If you plan on welding outdoors, then we recommend going with a gasless MIG welder. But if your welding is restricted indoors, then gas MIG welder can be an option. Gasless MIG welding can be done outdoors in different weather conditions.
Where gasless MIG welding lags behind gas, MIG welding is in regards to welding position. It is easier to weld vertically with gas MIG welding than welding with gasless MIG welding.
In regards to fumes, the gas MIG welder again comes out on top. Gas MIG welding does not produce as many fumes as gasless MIG welding. Nonetheless, there is protection equipment you can use to protect yourself from these fumes.
what you need to think about before Switching to Gasless MIG Welding
Before switching to gasless MIG welding, there are a couple of things you will need to consider;
Choosing the right welder
Gasless MIG welding requires a constant voltage power source. As such, you need a welder that can maintain the right voltage throughout the welding process. If the welder is incapable of maintaining the voltage, it will lead to mistakes.
Selecting the wire
Flux core wires used for gasless MIG welding comes in different sizes. The wire you choose has to be perfectly suited to your welding needs.
There is cleaning involved
While gasless MIG welding can be done on dirty metal surfaces, there is still some cleaning to be done. It is recommended to clean the metal surface between passes. This helps get rid of any contaminants that can cause fusion issues.
Gasless MIG welding is great for beginners and is friendly on your pocket. However, it does not suit every welding project. Therefore it is important to consider this. Nonetheless, for industrial projects, gasless MIG welding is a great option.
