Flux core welder is very similar to MIG welder, and in most cases, you can use one machine for both MIG and flux core welding. However, instead of using a shielding gas to protect the weld area, a flux core welder uses the flux core to generate the necessary protection from the atmosphere.
Flux core welders are powerful machines, and they are often used in the construction industry because of their high-speed welding capacity. There are also widely used in DIY and small shops, and they let you do anything from welding thin auto body sheet to thick sheet plate.
With so many machines out there, it is easy to miss out on the best flux core welder or pay too much for features that don’t meet your needs. We’ve done the research for you to provide you with some of the best options.
Let’s get started

How to choose the best flux core welder for the money
Flux core welders come in different designs, from true gasless welders to multi-purpose models that support more than one welding process. With so many options to choose from, how do you decide which is the best welder for your needs?
Here are some important factors you need to keep in mind when choosing a flux core welder for your welding needs;
Scope of application
One of the most important things that will determine the size and quality of the machine you buy is your welding needs and skill level. If you are a hobby welder or looking for something to enhance your DIY skills, you can go for a budget, entry-level machine to help you grow as a welder.
On the other hand, if you are looking to become a professional welder with one eye on the future, you can focus on the multi-process and high-end models that your budget can allow.
Ideally, the more the functions, the better quality of the welding machine, and this is a good thing, especially if you are looking for something that you can’t outgrow as you advance your skill level.
Flux core welder vs. MIG
One thing to note is that some MIG welders can accommodate flux core wire, making them ideal for flux core welding. However, you cannot use a true flux core machine for MIG welding because it is only designed to run a flux core wire. You’ll want to pay close attention to this detail, especially if you intend to add a shielding gas or try MIG welding in the future.
MIG welder uses inert gas fed through a hose into the weld, forming a shield that doesn’t allow contaminates, especially oxygen, into the weld. On the other hand, a flux core welder uses the flux to produce self-release gas used to shield the weld.
Flux core welding is often preferred to MIG when you need to weld outside, where the wind can blow away the shielding gas, hence increasing the chances of porosity.
The plate thickness is often one of the most important considerations when choosing a flux core welding machine. For instance, if you only intend to weld materials that do not exceed 1/4 of an inch, then you only need a device that can deliver about 130-140 amps. Anything thicker than that will require a more powerful machine like LOTOS MIG 175 with up to 175 amps of output.
Input power is also a major consideration, and it is mainly guided by the type of materials you need to weld. For instance, if you only intend to weld thin sheet metal most of the time, then 120 volts or less will be a good starting point.
On the other hand, if you need more power for your heavy-duty projects like equipment repairs, you may want to consider a 240-powered machine.
However, the best thing is to get a dual input welder that runs on both 120 and 240 volts to ensure that you have enough power for the type of project.
Flux core welders give you the opportunity of producing cleaner welders without using shielding gas. Investing in the best flux core welder will help you weld optimally regardless of your welding experience or level. We choose Forney Easy Weld 261 as our top-rated machine because of its compact design, outstanding weld quality, and ease of use. However, if you need something that you can use as either flux core or MIG welder, consider a multi-process like Weldpro 200 Amp multi-process Welder that can be used in both gasless and gas operations.
