10 Best Flux Core Welders in 2021 Reviews & Buying Guide


If you are in the market to buy a new welding machine for your garage, workshop, or any other industrial usage, then you will come across a wide range of options where different welding machines offer different functions. Out of all these various options, the best flux core welders mentioned in this article can be a great option for heavy-duty usage where you may have to make a lot of welds thanks to these features:

  • Current Output: Whether you are buying a flux core welder or any other type of welding machine, it is quite important to check its current output as a higher current output of 160 amps or 200 amps is going to offer much better performance than a current output of 100 amps or 120 amps in most cases.
  • Material Thickness: Even if you are getting a flux core welder that offers a high current output, it is not going to be useful for you if it cannot weld thick sheets of metal. Fortunately, most flux core welders mention a material thickness rating as ⅛ inch or ¼ inch where the higher latter rating is much better for heavy-duty usage.
  • Controls: Before you go ahead and start using your high-performance flux core welder for your workshop projects, it is quite important to check the controls offered by it. Without proper controls for the current output and the flux core feeding rate, you will not be able to make accurate and precise welds using your flux core welder.

Apart from these features and factors, you still need to consider much more before buying flux core welders. Hence, to help you in picking the right one, all the various flux core welders stated here also have their important specifications and options explained along with a comprehensive “Buying Guide” so that by the time you reach to the end of this article, you can easily buy the best flux core welder for you.

Buying Guide for the Best Flux Core Welders

In comparison to most other types of welding machines, a flux core welding machine allows you to weld a lot of pieces together in a short period of time. Thanks to its continuously fed flux arc welding process, it is one of the best options for heavy-duty usage.

And hence, we have already provided a few of the best flux core welders up above. Even though all these various flux core welders have been explained along with their features and options, you might be interested in learning more. If that is also the case with you, then make sure to check out this detailed buying guide for the best flux core welders:

Current Output

While buying a welding machine for your garage or workshop, it is highly important to ensure that it is a powerful one to ensure that it can be used for all kinds of projects. Thankfully, it is quite easy to get an idea of the performance offered by your flux core welder by simply checking its current output.

Talking about the best flux core welders stated above, most of them include current output ratings of around 120 amps which should be ample for the average user. However, if you want a flux core welder designed for heavy-duty usage, then you should go with models that offer a higher current output of 160 amps or 200 amps. This is due to the reason that a higher current output can quickly weld even thicker sheets of metal.

Material Thickness

Speaking of the thickness of the metal sheets on which you are using a given welding machine, a powerful flux core welder with a high current output is only going to be useful when it can be effectively used on thick sheets of metal. Thankfully, almost all flux core welders include a support material thickness rating that tells you about the thickness of the metal that you can effectively weld with.

Generally, this rating ranges between ⅛ inch and ¼ inch out of which the latter one is better. If your flux core welder supports a high material thickness, then it can be easily used on both simpler as well as heavy-duty projects where you may have to work on thicker pieces of metal.

Controls

Whether you have a powerful flux core welder or an entry-level made for basic usage, you cannot use it properly unless it offers you all of the necessary controls needed to handle a flux core welder. As for the flux core welders stated above, almost all of them offer versatile control options so that you can precisely and accurately weld everything that you need to work on inside your workshop.

This primarily includes the control options for changing the current output and the flux core feed rate. By adjusting both of these, you can effectively adjust your welding speed which is highly important if you want to ensure that all of your welds and joints are correct and done properly. Other than the dials for adjusting such settings and others, you can also find displays on a lot of flux core welders that can show you the current output in precise values to ensure that you have chosen the right one.

Accessories

If you have ever used a welding machine in the past, then you must know that you need a lot of accessories along with your flux core welder before you can start using it. And while you can buy such accessories separately, many flux core welders include them in the box.

This can include accessories like welding cables, power cables, welding hose, welding flux, carrying bag, tools, and much more. If your flux core welder also comes along with all these, then you can start using your welder right away. Not only that but such flux core welders also offer a better value for money to the user since you will not need to buy these accessories later on.

Duty Cycle

In case you wish to use your flux core welder for heavy-duty usage, then it is highly likely that you will be using your welder for a long time at one go. Although, you cannot use any welding machine including flux core welder continuously since it can heat up.

To prevent such heating issues, all flux core welders have a duty cycle rating which can be given as 25%, 40%, 50%, and others. Taking as an example, if your flux core welder has a duty cycle of 30%, then it more or less means that you can only use your welder for a total of 3 minutes in a span of 10 minutes. This means that other than the 3 minutes, your welding machine will not work for the rest of the next 7 minutes. However, if you wish to use your flux core welder for a long period of time continuously, then you will be glad to know that the duty cycle varies at different current output values. While it might be at only 30% at 140 amps, it can increase to 50% or 60% as you drop the current output to 60 amps or 70 amps depending on your flux core welder model.

Warranty

Those of you who are getting a brand new flux core welder for their garage or workshop would want it to last for as long as possible. This is due to a simple reason that most welding machines do not come in cheap. As a result, it is always a great idea to check the warranty included with your flux core welder to get an idea of its reliability. Fortunately, almost all flux core welders come backed by a 1-year long warranty. Due to this, you can rely on your flux core welder for heavy-duty usage for a fairly long time without any issues.

Conclusion

Just as you can tell by the name, a flux core welder uses a continuously fed flux core that is used for welding resulting in almost an automated welding process. Because of this, it can be a great option for large-scale projects where you might have to make a lot of welds.

Therefore, some of the best flux core welders have been stated up above alongside their details like features and factors. This is combined along with an extensive buying guide regarding flux core welders. And based on all this detailed information, here are some of our favorite recommendations for the best flux core welders:

  • Out of all the various flux core welders present up above, the Tooliom 200A flux core welder is one of the most powerful options thanks to its excellent current output rating of 200 amps.
