Last Updated on Nov 19, 2022

Who said flux core welders are only for professionals or experts? However, even if you are just a beginner looking forward to getting your hands on some DIY welding or repairing projects, nothing can stop you as long as you follow proper guidelines.

In this content, we offer you the affordable but best flux core welder list in the market.

We are aware that these are heavy-duty machines. So before you get all excited about swiping your card, it is necessary to do some research about the machine’s model, features, or price so that you and your flux core welder-buddy can keeping welding together for more years to come.

But before we give you a peek at our list, let’s understand the dynamics and practicality of flux core welding.

Introduction to flux core welding

Flux core is also known as Flux Cored Arc Welding or FCAW, a welding method that uses a tube-shaped wire conductor containing a flux within the inner core.

In flux core welding, the wire conductor feeds via a wire feed unit and needs coarse rollers for holding the tube-shaped wire without causing any damage. It’s recommended to FCAW outside, simply due to the smoke produced. It’s common to use fans or welding respirators when FCAW welding.

There are two types of FCAW– Self-shielded (FCAW-S) or Innershield, and Gas Shielded (FCAW-G) or Dualshield. FCAW-S consists of a flux that protects the molten weld pool and prevents both nitrogen and oxygen from acting up against hot metal.

In addition, FCAW-S provides great weldability with excellent removal and has a good reputation amongst the mechanical and chemical properties. All these factors make FCAW-S a standard choice for metal-related construction, repair, or erection.

Whereas in FCAW-G, the welding process occurs via shielding gas in which the supply comes directly from the gas nozzle. FCAW-G has a flux coating that quickly hardens compared to molten weld and relies on the repetitively-fed tube-shaped wire, which is essentially filled with metallic and metallic-oxide powders.

Uses of flux core welding

If you think flux core welding is only about fusing different metal parts by heating them, you need to rethink it again. Let’s have a look at the uses-

  • Apart from excellent penetration against dense joints, flux core welder can advance to various metal directions. Due to its simple and easy functioning, anyone can quickly learn it.
  • Another unique quality of FCAW is that it uses a shielding method that requires no gas tank, making it portable-friendly, but the technique releases excess smoke. Hence, it is advisable to use the machine around ventilated space.
  • FCAW has the highest deposit rate and can supply 25 pounds/hr. Therefore, FCAW is an excellent resource for industrial productions and repair, which deals with many requirements.
  • Overall, some regular uses of FCAW include- generic repair, manufacturing, pipeline welding, underwater welding, and shipbuilding.

Factors to consider while purchasing flux core welder

There is no denying that many welding machines are available in the market, which may confuse you. To make things easier, here are few features you should double-check while shopping so that you end up getting the best flux core welder.

Current Output

If you are on the lookout for a powerful machine that can work with any welding project, you might need to check the machine’s current output with at least an average of 120 amps. But if you are more into the big guns, the best flux core welder comes in 160 amps or 200 amps with high current output, and it is faster to weld thick metal.


No matter how excellent your equipment is, if it does not offer all the basic controls which are a must in a flux core welder, your machine is as good as a toy. One of the primary control options should include a feature to alter the feeding rate of both current output and flux core, as it will help you adjust the welding speed and create accurate actions for your welds. Moreover, having a display that gives legit current output status is also a bonus.

Thickness of the material

Even if your welder is powerful unless it can weld thick metal sheets, the whole purpose of getting such equipment is invalid. Therefore, while scanning for welders, keep your eyes on flux core welders, which provide a metal thickness rating. The standard rating starts from 1/8 inch or ¼ inch, and it will inform you how thick a particular metal is, and accordingly, you can do your welding.

Duty cycle

You must be aware that flux core welder works with heat, and there are high heating issues. So to prevent such a scenario, flux core welders provide a duty cycle rating such as 25%, 30%, 40%, and more. These ratings guide you to inform how many duty cycles your machine has covered and how long it can function within a given period. But if you want to use your device for a more extended period, you can get a higher current output as the duty cycle varies according to the current output and the model.


If you managed to pick a welder of your choice, ensure it provides accessories inclusively with the machine as some welding machines in the market sell without including the supplements. But there are also flux core welders, which provide for accessories in the packaging. The additions will consist of welding hoses, power cables, welding cables, and more. So if your find such a welding machine, get your hands immediately as they serve as an excellent deal, and you don’t have to purchase the accessories separately.


The warranty of any product becomes the deciding factor if the product is genuine and worth buying. So, you better watch out! For example, in most high-performance flux core welder, you will find one year warranty which makes the product reliable for usage and an assurance that the machine will last some good years.
