The best flux-core welder is able to deliver high-quality performance over a wide range of metals and thickness.

This technique does not require as much pre-cleaning unlike MIG welders, but it is still a good idea clear off as much dirt as possible, to give your project great results.

The process of combining several metals with the use of a hot iron and flux core is known as flux core welding. It has been in use for several decades now, though the advantages and disadvantages of it are much debated. This is the reason why this process is widely employed today, especially by industrial welding factories.

Buying Guide For Flux Core Welders 

If you already have an adequate MIG welder, then you probably can utilize flux core wires combined with changed polarity (to positive). You can also invest in a flux core welder if you think it would be beneficial to have an entirely separate unit for this purpose. In the long run, you’ll be saving money.

If you’ll only be using flux core for your welds in the near future, do a little bit of shopping around to see if you can acquire an affordable flux core welder. There are a number of things you should keep an eye out for in your shopping search.

Plate Thickness

Even if you have a standard plate gauge that you typically work with, it’s a good idea to look for a flux core welder that can handle a little bit more than that.

If you don’t, your new machine might have trouble keeping up with your traditional maximum. You also want room to grow. It’s never a good idea to buy a welder that you have already maxed out when you take it out of the box.

Multi Use or Single Use

If you have the potential for using gas to create precision welds, then you should look into a flux core welder that will work with both fluxless and flux-core wire. You’ll still be able to use your unit without gas.

Metal Type

A flux core welder works well with a variety of materials, but it does not work with aluminum. If this is the material that you’re traditionally using, then it’s helpful to have another piece equipment as part of your setup to cover all of your bases.

Frequently Asked Questions About Flux Core Welders

Q: Should I invest in AC or DC?

When looking for a welding unit, pay attention to whether a flux core welder comes with AC or DC output. You actually don’t get great results when you use AC output with a flux core welder. Stainless steel welds will also be a challenge with AC.

Q: Does the Quality of my leads matter?

When it comes to a flux core welder, the quality of your lead matters. The product needs to be thick enough in order to have adequate durability. Otherwise, you may have short life expectancies for your leads.

Look for the longest lead that you can get. Ideally, you want to strive for 10’ to 24’ leads for torch welding guns. Ground leads should be around 10’ to 12’.

Q: Is flux core welding a simple process?

The process of flux core welding is actually pretty simple. Once you’ve purchased a unit and have brought it home, you can have everything set up and in use within the hour.

Compared to some of the other forms of welding, flux core is pretty straightforward. You may need to practice a bit if you want to keep your slag levels low.


For us, the best in show here has to be the Hobart Handler 100. The price is good for what you get, and it’s designed just for the art of flux-core welding, plus the machine is synergistic which makes your welds go by faster AND look great.
