Are flux core welders any good?

As the process is mostly automatic, you wonder if a flux core welder is good compared to other popular machines. You should know that it is highly reminiscent of MIG and even and stick, which are two of the most popular types.

This method is better known as FCAW. Like the MIG method, you’ll apply filler continuously via the attached filler wire. However, it has a hollowed-out filler wire that contains flux. And just like Stick, no shielding gas is used. Instead, the flux itself does the shielding of the molten pool.

And because of their similarities, both flux core and MIG machines have interchangeable equipment. Certain models allow you to do both. You only need to make adjustments on the machine to switch from one mode to another.

However, TIG welders cannot be said since their processes are completely different. While MIG and TIG are often compared, flux core is a lot different from TIG.

If you are still a beginner, you will find that a flux core is good enough for all your basic needs.

Which is better?

Because of their similarities, people often wonder if MIG is better. After all, it is a favorite of many because you can produce work of good quality with minimal effort on your part. If this is already easy for many craftsmen, flux core arc is even more so. Many consider FCAW to be the easiest method around.

While it is often compared to MIG, its overall result is not as aesthetically pleasing. It produces a slag that you must remove afterward. Not only that, poor preparation and setup will yield unsightly porous results. It is a known issue with FCAW. It is more beginner-friendly than MIG. However, cracking and issues with weld penetration are also common. It is also a bit costlier overall than MIG is.

On the other hand, it is a much more straightforward process than welding. You can even fuse metals without cleaning and preparing the surface first for the weld joint. It also works with thicker metals, unlike MIG. MIG is only suitable for thin to medium-thickness metals. And since it has the highest filler deposit rate, you work on materials a lot faster. No gas involved means you can even work outdoors with FCAW.

In some aspects, MIG is better than flux core. On the other hand, the latter also has advantages over the former. But regarding the work’s quality, MIG is still better overall, particularly in creating a clean result.

Is Flux Core Right For You

Flux core may be right for some, especially for people getting started in the industry. It has some limitations that mean it will easily not be everything you need for it to be. You may soon find yourself asking for more. 

flux core

MIG and TIG are often the two types that pros will use. The specific type depends on the type of work being done. It is more commonly the case that pros use a TIG welder rather than a MIG one. Does that make the technology right for you as well? Not necessarily. It could be the case, depending on your goals. 

If your needs are modest, these flux core welders can be right for you.

Suppose you have started looking around the internet. You will also quickly find out that these types come with very different capabilities. Some of them are barely doing the work that a pro would need to do. In contrast, other machines will cost you thousands of dollars. Other machines may also weigh the same as the average motorcycle.

Let’s start by taking a look at some of the differences between MIG & TIG. Let’s start by looking at some of the different types of material that the two processes can handle. You got that right. Not every single type of process will handle every single type of metal. 

flux core welding

Will you be working on a specific type of metal? The first thing you should be making sure of is that the type you are choosing can handle it. The best reason why you shouldn’t get started with MIG is that you will quickly run into its limitations.

While both types will work on aluminum, you are better off getting TIG if your needs are many. It will easily let you branch into other types of metal.

There are multi-process welders available on the market that can do this. 

Suppose you are looking for an option that can do both flux core and a range of other options. We encourage you to check out the Lincoln Electric POWER 210 MP Multi-Process option. Even if it is more expensive than other models, it’s a great machine.

At a max wire feed speed of 500 ipm, it’s a good machine to get you started if you are willing to spend the money. It’s also very portable, weighing only 40 lbs.

People may be talking about MIG and TIG seemingly interchangeably. That’s wrong. The two are very different processes. They will both use filler metal to melt the various metals together. With TIG, you are holding the filler metal in one hand and the torch in the other hand. With MIG, the filler metal comes out of the torch. It allows for a faster weld, although one of lower quality. 

Besides, one of the main reasons people choose TIG over MIG is because of the increased control you have. It makes TIG preferred when working with vulnerable pieces of metal that require more control. Aluminum is a good example of that. There are various other options we didn’t consider here, including the Forney Easy Weld 261. We hope you purchase the one that works for you as they come at different prices.

Before you proceed, make sure to see if the model comes with a ground clamp and a spool gun so you can have a great welding experience. You may be about to head out and get argon to get started. We know it can be messy to follow the specifications on the products or read a welding chart to figure out your welding needs.

Why you can trust us and how we picked?

You can trust us to pick any of the above-listed best Flux Core Welders and stay worry-free. That is because we have done all the research on your behalf. We have tested and taken inputs from the industry people as to which welder gives the maximum output at minimum cost.

Factors to consider

Types of metal

It’s important to keep in mind the types of metal that you will be working with your flux core welder. For harder metals, a more powerful welder is required.


Smaller flux core welder are not too heavy to carry. They can be easily carried from place to place and get the job done. But if you are planning to get a bigger flux core welder, then the portability will be a challenge.


A very important aspect of flux core welder is pulse welding. It allows the welder to weld the thin sheets of metals that too without making a hole in them. One must look for this feature before buying one.

Foot pedal

Welding is a tiring and complicated process. If the equipment is right, it’s a breeze to complete the job. A foot pedal is that feature that acts as a companion to the person carrying the welding job. Always look for the welder with a foot pedal so that only hands do not get all the stress.

How much does the best best flux core Welder cost?

Flux core welders come in various sizes with different levels of output. But the best ones start at around $400 and will cost you not more than $2000. The welders in this range work well and get the job done without making a hole in your pocket.

What is flux core welding used for?

If you’re thinking of going industrial with welding of thicker metals, flux core welding is the best option. It is most secure and guarantees the best welding of contaminated and even rusted metals. It is also easiest to master in the shortest amount of time. It does not even require a great deal of dexterity. So it’s used by those who want to start in the skill.

Is flux core welding any good?

Flux core welding is appropriate for thicker materials. It offers greater penetration and a more secure joint. Because of the strength of the joint it provides, it is often used for manufacturing and shipbuilding purposes. It’s also great for joining together rusted metals.

How thick can you weld with flux core?

An average flux core welding machine can weld up to 1/4″ inch of metal. Note that this is almost double of 12 gauge steel that MIG can weld.

Is flux welding good for beginners?

Yes. Since it does not require shielding gas, it is easy to use. This makes it great for beginners in welding. It is also portable and more convenient than MIG welding.

Let’s look at the relatively simple process of flux core welding.

How do you weld with flux core?

  1. Make sure the machine is set to DC.

    Since flux core is a gasless process that runs on the direct current, you must switch the settings to DC electronegative. Otherwise, you will have trouble running the machine.

  2. Set the machine to an appropriate voltage

    You’re going to want to set the machine to the right volts. For a simple fillet joint, you’ll need 18 volts on the machine.

  3. Put on your safety gear.

    This includes your welding helmet or goggles. You can use gloves and a lab coat if you have one. Avoid clothes made of synthetic or polyester fiber.

  4. Start the welding

    Keep your eye right behind the protruding wire when you weld along the joint. Keep an eye on the width of the joint. Oscillate slightly along the welding line. It’s normal for the wire to move off track a little bit.

  5. Seal it up

    When you’re done welding along the line, take the machine back an inch and retrace your weld. This seals the weld perfectly for absolute security. And you’re done with your first flux core weld!
