Best Flux Core Welders For the Money – Top Picks & Reviews

It is a challenge to choose the right welder, right? First, you need to pick what type of welding you will do for your project. Once you pick one, you now have to select the welder you will use. But because there are so many models being sold, this can be such a daunting task.

You don’t have to always rely on what the sales clerk will tell you when looking for the best welder for the money. Choosing a flux core welder suitable for your needs, whether you are a beginner welder or not, can be easy if you let us help you out.

In this article, we will review our top picks and explain why these flux core welders deserve to be part of your workshop.

Need a waste oil heater, engine driven welder or a plasma cutter? We can help you find those, too.

Is a Flux Core Welder Any Good?

Since the process is mostly automatic, you might be wondering if a flux core welder is any good compared to other popular welding machines. What you should know is that flux core welding is highly reminiscent of MIG welding and even and stick welding, which are two of the most popular welding types.

In flux core welding, better known as FCAW, applying filler is also continuously done via the attached filler wire just like in MIG welding. However, it has a hollowed-out filler wire that contains flux. And just like stick welding, no shielding gas is used. Instead, the flux itself does the shielding of the molten weld pool.

And because of their similarities, both flux core and MIG welders even have interchangeable equipment. In fact, certain models of welders allow you to do both. You only need to make adjustments on the machine to switch from one mode to the other.

However, the same cannot be said about TIG welders since their welding processes are completely different. While MIG and TIG welding are often compared to each other, flux core welding is a lot different from TIG welding.

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

Is MIG Welding Better than Flux Core?

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

While it is often compared to MIG welding, its overall result is not as aesthetically pleasing. Flux core welding produces a slag that you must remove after welding. Not only that, poor preparation and setup will yield in unsightly porous welds, which is a known issue with FCAW. And while it is more beginner-friendly than MIG welding, cracking and issues with weld penetration are also common. Flux core welding is also a bit costlier overall than MIG welding.

On the other hand, flux core welding is a much more straightforward process compared to welding, as you can even weld metals without needing to clean and prepare the surface first for the weld joint. It also works with thicker metals, unlike MIG welding that is only suitable for metals that are thin to medium thickness. And since it has the highest filler deposit rate, you weld materials a lot faster. No gas involved means you can even weld outdoors with FCAW.

In some aspects, MIG welding is better than flux core welding. On the other hand, the latter also has its own advantages over the former. But when it comes to the quality of the weld, particularly in terms of creating a clean weld, MIG welding is still better overall than flux core welding.

Super Deal MIG 130 Flux Core Welder

The Super Deal MIG 130 Flux Core Welder is one of the most affordable units around. Because of its low price, it is understandable that it is not as feature-laden as its pricier counterparts. Even the build quality is affected, as it is crafted using PVC and not stainless steel. Despite its flaws, it is still sufficient for your basic welding requirements.

This welder allows you to choose between 4 speed and 10 wire feed settings and is equipped with a safety control. It may not be as powerful as other welders but you can still weld metals up to 1/4 inch. But since it is AC-powered, the resulting weld is not that neat. Do note that you can do both FCAW and MIG welding with it.

Pros:

  • Very affordable
  • Capable of both MIG and flux core welding
  • Compact and lightweight
  • Setting up is effortless
  • Equipped with variable speed settings, including for controlling the speed of wire feeding, and an on/off safety control

Cons:

  • Poor built quality compared to other similar welders since it is made of PVC
  • Resulting weld is not that clean because it is AC-powered
  • Reportedly prone to overheating, despite having protection against it
  • Not ideal for heavy-duty nor frequent use
  • Has only four amperage settings ranging from 50 to 130

Reboot MIG150 Flux Core Welder

For users who also prioritize practicality, the Reboot MIG150 Flux Core Welder is sure to be a hit. Not only is it one of the most reasonably-priced models around, but it is also one of the most energy-efficient because it is an inverter model – DC power is used for an AC output. While it is a bit more expensive than the cheapest models, you end up saving in the long run because of its energy-saving features.

While most of the models can only offer flux core and MIG welding, this model also allows you to stick weld, making it a practical choice for those who want to use different welding types as well. Not only that, but it can also weld metals up to 1/3-inch thick. While users are so far quite satisfied with it, inverter technology in welding is still relatively new so long-term use is still up in the air.

Pros:

  • Most energy-efficient model, being an inverter model
  • Allows you to do three types of welding: FCAW, MIG, and SMAW or stick welding
  • Very portable and lightweight
  • Can be used to weld thicker metals compared to most flux core welders

Cons:

  • Stress test is yet to be done on any inverter-type welder, so its build quality is unknown
  • Risky to use because experts have yet to determine how long it can last on average and any hiccups users may expect when it is in use

While there are other good flux core welders out on the market, the ones we reviewed are our top picks because they give the best value for money, regardless of your budget.

If you plan to also learn MIG welding, you can opt for a welder that offers a dual-mode like most of the flux core welders on our list. That way, you get to save more because you no longer need to buy a separate MIG welder.
