Flux core welding is easily one of the best welding processes.
It’s not hard to see why; this technique uses a flux that causes metals of different strength and thickness to melt at varying temperatures and requires minimal cooling time. Flux core welders are versatile and suitable for a broad range of projects.
The best flux core welders are easy to use and do not pose the common problems associated with other types of welders. However, finding the right device may become a herculean task owing to the copious amount of research involved.
Fortunately, we’ve moved a step ahead to provide you with this review of the top six flux core welders available on the market today. Enjoy!
Top-rated Flux Core Welder For The Money in 2020
Advantages of The Flux Core Welding Machine
Flux core welding is a semi-automatic welding process. This process requires a continuously fed wire electrode containing flux and a steady current power supply for welding (i.e. it uses a tubular wire filled with a flux). During the entire welding process, the flux inside the electrode melts and shields the welded area.
Some of the advantages of the flux core welder include:
- Versatility: It is suitable for a variety of applications; can be used to weld steel, stainless steel, copper and aluminum etc. This machine also works perfectly on painted, dirty or rusty materials
- Flux core welders can be used under windy weather conditions
- The Continuous wire feed technology makes the flux core welding machines easy to operate, simplifies training and supervisions
- Flux core welding has a relatively high metal deposition rate.
- It also provides you with deeper penetrations for welding relatively thick sections.
Disadvantages of the Flux Core Welding Machine
Even though the advantages of the flux core welding machine cannot be overemphasized, and just like all other electrical devices, the flux core welding machine has its own disadvantages. Some of them include:
- During the welding process, a lot of spatter is produced and this needs to be cleaned up regularly
- Require slag removal after welding
- Inappropriate selection of consumables and parameters leads to a reduced weld toughness

MIG Welder VS Flux Cored Welder
Talking about the comparisons between the MIG welder and the Flux Core Welder, a lot of people are of the opinion that the two is similar. This is true in terms of the welding procedures but the truth of the matter is that they are two different things. A MIG Welder can be said to be another flux-core welding machine. There is hardly any change on the machine except the filler wire that is used. The energy found in both these machines is generally consistent voltage and the electrode is fed by a wire feed system.
The main line differences between these welders are the filler wire and the gasses used. For a MIG Welder, the welding electrode used is with no doubt a good wire that requires a shielding gas to shield the welded area.
On the other hand, the flux-cored wire used in flux core welder is tubular and has a ‘T’ about the designation. Whenever you view a ‘T’ around the filler designation the first thing that will come to your mind is that this is a flux-cored wire.
One important thing about this tubular wire is that it incorporates a flux center that will shield the weld without the need to add any filler metal. The flux core electrodes may be used for welding heavy plate for its deeper penetration ability.
Factors Consideration For Flux Core Welding Machines-Buyer’s Guide
Flux Core Welding is not a new thing, being dated as far back as the 1920s. You may already have a clue on how versatile a flux core welder is, but finding the right machine that will serve your needs can be a tough task. And of course, choosing anyone you come across is not the best decision to make. Below are some of the factors you need to put into consideration when buying the best flux core welder.
Understand your needs
First of all, you need to keep in mind exactly what you need to use the welder for. Whether for small domestic use or for small repairs in the garage. Whether for use in a small fabrication shop or for heavy duty applications. I believe you do not want to buy a welder that has either less power than you need or more power than you surely require.
The cost is by far beyond the price, but what you get from the money you invest. There are welders that are versatile and performs excellently great costing less than the half the cost of a unit with a number of issues here and there. A manufacturer may wish to slash down the price of their product and even give a guarantee. But if the machine doesn’t perform consistently, it will be difficult for you to use it and all you end up having is a cheap guaranteed piece of trash.
I believe the last you would want to observe is seeing your newly bought machine fails or its part breaking during normal use. Some of the times manufacturers choose to take shortcut routes to make their products lightweight or to add to its performance. But as it is with shortcuts, they are only good at falling short but not great. A plastic casing may make the machine easier to carry but will not stand a normal wear-and-tear or a rough use as the case may be.
Power and duty-cycle
A good flux core welder should have a higher duty cycle and a good power rating. The duty cycle determines how efficient the machine will be, and the machine will be great if you have different power options
Whether as a beginner or a professional, performance is very important. It will be a wise decision to practice before tackling the main job. Amidst all circumstances, the welder should perform perfectly as advertised. There reports here and there were some welders had to work with a particular gage of wire to get a consistent good flux core welds, and this is mostly against the actual instructions from the manufacturer.
There are two types of shielding options. One is self-shielding and another is gas shielding. In gas shielding, one will need an extra gas bottle. While in the self-shielding option, one will not need any gas bottle rather an additional jack. This jack is simple to move. For simple mechanism and conveniences, most people prefer self-shielding.
The overheating proof
Overheating is a serious threat and can ultimately cause tremendous damages to the material. Hence, this is a very important factor to consider.
Repair, maintenance and easy to get spare parts
This may seem unimportant but really very crucial. Welding Machine does need repair and maintenance from time to time. Make sure the spare parts of the brand you are going for is easy to get in the market. If not we suggest you go for another MIG welder. Nevertheless, choose the best.
Portability, weight, and size
What you intend to use the machine for determines the size of the machine you need to buy, be it a mobile or a stationary. For a mobile workshop, you will definitely have to consider portability for the purpose of transportation. Amidst all circumstances, the first factor to consider is the quality of the machine then the size and weight. The size is so important for you wouldn’t want to be moving around with such a voluminous welding machine.
From what you have read above I believe you have the basic knowledge on the flux core welders. You have also read the reviews of the six best flux core welders. By this time, you should know exactly what you need.
We hope this review will make it easy for you to make the right decision when choosing the best flux core welder for your needs. For best results, we recommend you try the Hobart Handler 140-MIG Welder. You sure won’t regret your decision.
