7 Best Flux Core Welder Reviews

1. Goplus MIG 130 Flux Core Welder - TOP PICK

Goplus MIG 130 Flux Core WelderGoplus MIG 130 Flux Core Welder

I have put it at the top of the list because of its ability to be used for both MIG welding and flux core welding.

The price is really low and weight is roughly 35 pounds.

This is the most lightweight and less expensive machine in the market.

The small size of it makes it convenient to store and also allows portability. 

Attractive Key Features:

Made of good quality material:

It is made of stainless steel and it is painted by durable yellow paints.

This ensures a long life-span and long-lasting service by the machine. 

Adjustable welding speed features:

There are 4 levels of electricity flow settings.

You can adjust the flow of the current by these 4 buttons and the maximum range is 2 and the minimum range is 1. 

There is also a rotary knob which controls the wire feeding speed.

There are 10 levels of speed and you can feed wire as per your choice. 

Portability with wide application:

Here is good news for you. 

The GoPlus MIG 130 is capable of welding a wide variety of metals.

If you are looking for a welder that can weld steel and iron then it is what you should go for.

The welder fits perfectly with your DIY projects and gives a professional finish.

The carrying handle allows you with the portability of carrying it anywhere you want.

The lightweight of the welder makes it easy to carry and easy to store.  

Other complimentary features:

There is a two-way ventilation system in the machine so that heat can dissipate.

The welding gun has an on/off safety control for your maximum safety. 

The welder also comes with a reel of 0.9 and 0.55lbs welding wire and a brush for chipping. 

Perfect for light use:

As I have mentioned earlier, the welder is of light weight.

Being so, it is not strong enough to handle heavy work.

If you are working on any household works or in any sorts of DIY projects then you should give this welder a try.

You will be amazed at the convenience of the welder. 

Worth the price:

The welder is a complete package of welding.

That you are getting within such a small budget is certainly too many to have. 

You won’t regret investing your money on the welder. 

About warranty:

Goplus offers only 6 months of warranty for their product.

I know this is not an extensive period.

For such an inexpensive machine I think that is worth it.

You will even get a replacement if you send it back within 30 days. 

Consideration:

Not for heavy works:

I have mentioned before already that the welder is not for heavy tasks.

The power output of the welding machine is only 110V which is not that much great if you want to do heavy work. 

Unable to fuse thicker metal:

As the welder is unable to produce high power voltage that is why you won't be able to fuse thicker metals by this welder.

Steel sheet is within the range of this welding machine.

PROS

  • 4 adjustable welding speed features.
  • Perfect for DIY projects.
  • 6 months of warranty.

CONS

  • Not for thicker metals.

As final remarks I would like to tell you that this is a great product with outstanding features.

The performance and the service is more than the price.

So that you can adjust the speed and voltage more precisely. 

Metal welder:

The welder is capable of welding a wide range of metals.

Oh Yes! You have to do it using a spool gun.

Sadly it doesn’t come with the package. You have to buy a separate one.

The welder runs on 110v/60hz single-phase voltage.

The duty cycle is 10% at 105 amp and at 35% when it is at 60amp.

FLux core welder: Buying Guide

There are some MIG welders in the market which you can use to do flux core welding.

You have to change the settings, remove the gas canister, and change polarity to electrode positive. 

On the other hand, there are some welders which are made for only doing flux core welding.

They are cheaper than the MIG welders and do better welding.

If you want to do flux core welding only, then choosing the second option will be a better choice. 

Not only this, but there are also so many other things which you have to decide before making any purchase decision.

Let’s dive right in...

The thickness of the metal:

You would definitely want a welder which will be able to do a little bit more than your regular welder in case of metal welding.

A machine which can weld thicker metals makes your welding easier.

So, look for a welder which can weld up to the maximum gauge of metals. 

There is a traditional belief that the bigger the amperage range, the thicker plate you can weld.

Deal with this belief with caution as some manufacturers buck this tradition.

Check and double-check the manufacturer guideline before making the purchase.

Single or multiple purposes?

You can use multiple welding by using a MIG welder.

That’s because a MIG welder can do welding with or without gas.

This will give you more flexibility of work, but it will cost you more money. 

If you are a good welder of gas and if you are confident that you will be able to do clear welds using gas, then you should invest on a machine that is capable of doing flux core welding.

You can consider Hobert 140 or Lotos MIG 140 if your choice is the above. 

Type of metal used:

There are so many welders in the market which can weld different materials.

Flux core welding machines are not really compatible with aluminum.

You should go for the multi-purpose welders if you want to fuse aluminum. 

Type of electricity:

Remember to check what type of output your welder has.

Is it AC or DC?

If the output is AC then you might not get the best results.

You will be able to fuse metals and join them together.

You might struggle a little bit with stainless steel as well. 

Lead quality:

This might sound trivial but it is a fact which can’t be denied.

If they are not thick, long, and durable enough then you might not get the result which you are expecting. 

You can go for the longest and thickest lead you can get.

This makes a huge difference in your type of welding experience. 

About the wire:

The diameter of the wire and the diameter of the reel in which the wire comes are the two factors which are to be considered. 

A household working generally deals with 0.30 diameter wires and the diameter of the reel is 6 inches.

If you are planning to do some thicker beads, then it would be handy for you to run 0,35’’ flux wire. 

It would be better if your machine can handle 8-inch reels because the reels of 6 inches run out quickly.

It will cost you less money and does not require replacing now and then.


Let's wrap it up:

We have reached the very end of this article for the best flux core welder.

I have given you my top 7 welders which are the best according to my research. 

Now what you have to do is make a decision by considering the buyers guide I have given above.

As with any welding process, a good welder reduces the struggle to half.

All you have to do now is select a welder that matches your skill level, your purpose, and make the deal.

I hope you make the best decision.
