Factors to Consider Before Purchasing the Best Flux Core Wielder

A flux core welding machine allows you to quickly join many components together in comparison to most other forms of welding equipment.
One of the greatest solutions for heavy-duty use is its continuously fed flux arc welding method.

As a result, we’ve listed a few of the top flux core welders above.
You might be curious to learn more even though all of these different flux core welders have had their features and options discussed.
If that applies to you as well, be sure to read my comprehensive shopping advice for the top flux core welders:

Current Output

It is crucial to get a powerful welding machine when purchasing one for your garage or workshop so that it may be used for various jobs.
Fortunately, it’s pretty simple to gauge your flux core welder’s performance by looking at its current output.

The majority of the top flux core welders mentioned above have current output ratings of about 120 amps, which are more than enough for the average user.
However, models that give a larger current output of 160 amps or 200 amps are the ones to choose if you want a flux core welder made for heavy-duty use.
This is because thicker metal sheets can be swiftly welded with a higher current output.

Single or multi-purpose usage

MIG equipment can be used for both gas and gasless welding; this is a dual function. A dedicated flux core welder will suffice if you never want to be concerned about using gas when coil welding.

A multi-purpose MIG machine that can weld both flux-cored and fluxless wire is what you should get if you want the option of employing gas to create a cleaner weld. The Lotos MIG140 is an excellent choice because they can weld in both gas and gasless operations.

Material Thickness

When it comes to the thickness of the metal sheets being used, a strong flux core welder with a high current output will only be beneficial if it can be utilized efficiently on thick sheets of metal.
Thankfully, the majority of flux core welders have a support material thickness rating that indicates the maximum thickness of metal that can be successfully welded.

This rating often falls between 1/8 inch and 1/4 inch, with the latter being preferable.
If your flux core welder can handle thicker metal pieces, it can be used for both light-duty projects and heavy-duty jobs that may require working with thicker pieces of metal.


You cannot use a flux core welder effectively unless it provides you with all of the controls required to handle a flux core welder, regardless of how powerful or basic it is.
Regarding the aforementioned flux core welders, almost all of them include a variety of control settings so that you may precisely and accurately weld everything you need to work on within your workshop.

The main controls for altering the current output and flux core feed rate are included here.
You can successfully modify your welding pace by altering both of these, which is crucial if you want to make sure that all of your welds and joints are right and completed correctly.
In addition to dials for modifying these and other settings, many flux core welders have displays that can show you the current output in precise figures to make sure you have selected the proper one.


If you have ever used a welding machine, you are aware that a flux core welder requires a number of accessories before it can be put to use.
Even though you may purchase such accessories separately, many flux core welders come with them already installed.

Accessories such as welding cables, power cables, welding hose, welding flux, carrying bags, tools, and many more may fall under this category.
You can use your flux core welder as soon as it arrives if it also includes all of these.
Not only that, but these flux core welders also give the consumer a greater value for their money because they eliminate the need for additional purchases of these accessories.

Duty Cycle

It is very likely that you will use your flux core welder for a significant amount of time at once if you want to utilize it for heavy-duty work.
However, as it can heat up, you cannot continually use any welding equipment, including flux core welders.

All flux core welders feature a duty cycle rating that can be specified as 25%, 40%, 50%, and other values to avoid these heating problems.
If, for instance, your flux core welder has a 30% duty cycle, that essentially means that you can only utilize the welder for a total of 3 minutes during the course of a 10-minute period.
Your welding machine won’t operate for the remaining 7 minutes after the initial 3 minutes.

However, you will be happy to know that the duty cycle varies at different current output values if you intend to use your flux core welder continuously for a lengthy period of time.
Depending on the model of your flux core welder, it may be only 30% at 140 amps but rise to 50% or 60% if the current output is reduced to 60 amps or 70 amps.


You would want your new flux core welder to endure as long as possible if you were buying one for your garage or workshop.
This is owing to the fact that the majority of welding machines are not inexpensive.
As a result, it is always a wise decision to look over the warranty that came with your flux core welder to determine how reliable it is.
Fortunately, a 1-year guarantee is included with practically all flux core welders.
As a result, you can use your flux core welder for heavy-duty work without any problems for a significant amount of time.

Frequently Asked Questions

What is Flux Core Welding?

By preventing oxygen from entering the welding process, gas shielded welding enables the creation of clean welds free of oxidation or contaminants. With MIG welding, a hose supplies an inert gas to the welding process, which flows around the metal electrode to create an environment that prevents oxygen from getting into the weld.

When you weld outside in a breeze, the shielding gas may be blown away, leaving your weld open to oxidation and porosity. Engineers have devised a welding wire with a hollow core that is filled with a flux mixture as a solution to this issue. The flux on an arc welding stick electrode functions similarly to this flux core wire. The flux core, which transforms into gas and shields the weld, is melted by the wire as the metal heats up and melts.

Because a breeze won’t destroy your weld the same way it will with a MIG machine, flux core welding is actually superior to MIG welding in several aspects. Of course, when there is too much wind, it is impossible to weld, but flux core welders can produce excellent work in conditions where a gas MIG machine cannot.

Do You Need MIG or Can Flux Core Work?

MIG machines can operate flux core, but not all flux core welders can function as real gas MIG machines. This is one thing about flux core welders.

It can be difficult to understand this point because many flux core machines that simply function as wire feed welders are labeled with the word “MIG” in their model names even though they aren’t technically MIG machines. If you subsequently decide to try MIG welding, this is a crucial point to remember.

Can You Weld Aluminum With A Flux Core?

No. Flux core wire is incompatible with aluminum. Because it doesn’t get hot enough, the weld would be of low quality.

Even though the flux core wire’s package indicates that it can be used with aluminum, there will be a little print stating that “Argon gas suggested with use” in order to protect the weld while welding aluminum.

How thick can you weld with flux core?

As opposed to MIG, flux core welding often only requires one pass. The gauge of the flux core wire and the power being delivered through the welding machine are the two key determinants of thickness. You can weld up to 1/4″ thick steel on 115v house power with.35″ wire, which is the standard setup for at-home welding. You can weld up to 1/2″ steel if you can operate on 220v power.

Do you push or pull flux core welding?

You pull the weld with flux core welding. This is a result of the large amount of slag produced by the flux wire’s intense arc. Additionally, you should lift the welding handle just above the metal’s surface at a 25-degree angle. The weld should then be progressively pulled across the seam of the weld.

What causes wormholes in flux core welding?

Wormholes or worm-tracking in flux core welds can result from a multitude of problems, like other welding failures. Check to determine if the spool of flux core wire has any moisture. Wormholes can also develop in the vicinity of a weld when it is extremely humid or moist. Try recalibrating your ratios as another possible cause could be that your voltage is too high.

Do you need shielding gas with flux core wire?

Flux core wire is naturally self-shielding, hence a shielding gas is not necessary. In actuality, the shielding gas is produced when the flux within the wire burns on the weld surface. For specific FCAW-G flux-cored wire types, shielding gases are available. You won’t be utilizing them with your at-home kits, though. Most inexpensive flux core devices lack a shielding gas input.

Can you use MIG wire in a flux core welder?

Depending on the machine you bought, you may need to change the wire that is utilized in the welder. On my list, I have some welders who can do MIG and FCAW welding. Yes, you may use MIG wire in the flux core gun on these machines. However, as MIG wire needs a shielding gas to weld, you cannot use it if the machine was not configured for inert gas.

Final Verdict

Unquestionably, having a welding machine in your shop brings peace of mind. You have the ability to make whatever needs to be repaired or created.

The simplicity of a flux core welder amplifies its potency. Both a shielding gas and fiddling with a feed pedal are not necessary. Anyone can learn how to use flux core welding. That is its main advantage for you.

I am aware of your desire to learn to weld. With my list, you should be able to choose a machine that meets both your needs for welding and your budget.

If you want my opinion, the Lincoln Electric Easy MIG 180 isn’t the greatest flux core welder on my list. Undoubtedly, a 220-volt breaker is required to operate it. However, it can weld both little and large operations easily and safely provided you have the ability.
