Do you own a construction company, or want to do the welding projects on your own? Then having a Flux Core Welder is a must for you.
A flux core welder is far better than general MIG welding as it operates on Flux Core Arc Welding (FCAW). Unlike MIG welding, FCAW is gasless, it means that it doesn’t require a shielding gas, like argon and it is the easiest welder to set up. These are user friendly and you can learn to weld just after an hour of practice.
Want to know the best part?
Flux core welding is the most affordable form of welding that you can do and it’s great for beginners and for those who are learning the art of welding.
The market is flooded with a vast collection of flux core welding machines and we know that it’s a very tough decision for you to choose between them. So, we are here to guide you by giving all the positive and negative aspects of the top flux core welder available in the market.
So, without wasting much time, let’s have you a quick glance over the list of best flux core welder that we have collected after doing lots of research and testing:

Q: Is flux core welding any good?
Ans: Yes, flux-core welding offers greater penetration, which is great for working with thicker joints. It also allows the welder to travel in different directions and hold the torch in a number of directions.
Q: What can a flux core welder weld?
Ans: A flux core welder can weld thicker metal; thus, it is ideal for heavy-duty or industrial applications.
Q: How much do Flux Core Welders make?
Ans: It all depends on the experience of a Welder. A mid-career Welder with 5-9 years of experience can earn an average total compensation of $18.84 based on 726 salaries and an experienced Welder with 10-19 years of experience can earn an average total compensation of $20.03 based on 720 salaries.
Q: What flux core welding and what is it used for?
Ans: A flux core Welding is a process of welding that operates on Flux Core Arc Welding (FCAW). Unlike MIG welding, FCAW is gasless, it means that it doesn’t require a shielding gas, like argon. Flux Core Welding is used for welding structural steel, heavy equipment repair, shipbuilding, bridge construction, and many other applications.
Q: How to practice flux core welding?
Ans: To practice flux core welding, firstly you must gather Flux Core Welding Supplies and Equipment, then prepare the workshop. Secondly, prepare the metal and wire and set the voltage and amperage according to the thickness of metal you want to weld and then use the Pull Technique to weld and finally clean up your piece.
Q: Flux core welding settings
Ans: The basic Flux core welding settings for Horizontal welding is given below:
Basic Parameters for Vertical welding are given below:
Problem with welder sputtering
Excessive resistance anywhere along the circuit of the welder can lead to a wide range of problems, including a sputtering. This problem occurs because resistance in the circuit reduces the amount of current that can flow to the welding arc and when the power source senses the reduced current at the arc it sends a stream of voltage in order to overcome the restricted current flow. Due to the increased voltage, sputtering occurs which leads to poor and inconsistent weld quality.
Flux core welding polarity
Flux-cored welding needs DC electrode negative or straight polarity. The polarity connections are usually present on the inside of the machine near the drive rolls.
Flux core welding aluminum
Aluminum is an exotic metal and most flux core welders cannot weld it. In order to weld aluminum, a better option would be to braze/solder aluminum together with a cheap propane torch. For aluminum welding, gas is the best way and you will often need a spool gun.
A Comprehensive Buying Guide for You
Have you decided which flux core welder you want to buy? If not, then please look at our buying guide which will help you to decide the best flux core welder for you.
The thickness of the metal you want to Weld:
Before buying a flux core welder, you must decide the purpose of using it that is whether you want it for your personal use like for light fabrication, farm, home, and auto projects or you need it for heavy industrial projects to weld thicker metals.
One thumb rule for deciding this is to check the amperage of the welder. If it has higher amperage, then it means that you’ll be able to weld much thicker materials. Welders with 30-40 amps are generally suitable to weld a 1.00mm sheet and are usable in 0.8mm sheets.
This is also one of the important factors that you must take into consideration before buying a flux core welder. The duty cycle shows the time period for which you can continuously use the welding machine before it needs a rest.
For example, if the duty cycle of the Welder is 30% at 90 Amp, it means that the welder can be used continuously for 3 minutes at 90 amp and after that, it needs 7 minutes to break time.
Portability (Weight and Size):
The flux core welder that you are going to buy should be compact and portable which means its size and weight should be reasonable so that you can carry it easily along with you anywhere you want.
Thermal Overload Protection:
This feature of the welder decides its durability. Thermal Overload Protection plays a very vital role in preventing the overheating of a welding gun. The welder having this feature automatically get shut down as soon as it starts getting overheated and restarts itself after it gets cool down. As a result of this, your welding machine will continue working properly without any trouble.
The welders having this type of feature are relatively higher in price then the others, but if you can afford to pay more then it is highly recommended.
This is also an important aspect to decide whether you want to go with some reputed brands or with some less-known company and want to take a risk.
Before deciding this, just keep in mind that you are not going to buy any welder every day. The famous brand gives you a great after-sales service, trust, warranty, and another extra service, this means you don’t need to bear the repairing cost if your welder will face any technical issue. This also reduces your maintenance and repair costs.
The quality of the lead used in your welder makes a huge difference in its use over the whole period. Moreover, it will make your welding experience more enjoyable and gives you higher confidence.
More precisely, we can say that the length of ground leads should be from 10′ to 12′ and that of torch leads should be from 10′ to 24′. Not all leads come at this length, but the more the length of the lead the more you will feel freedom in moving your welder.
