Flux core welding and general MIG welding are similar methods used for both outdoor and indoor welding projects. However, flux core welding has certain advantages, especially when dealing with metals that are prone to galvanization, rusting, and other forms of corrosion. For hobbyists and DIY enthusiasts, a flux core welder is a more suitable choice.
To assist you in making an informed purchase decision, we have compiled reviews of the best flux core welders available for online purchase. Additionally, we have included a detailed buying guide that highlights important parameters to consider before making your final decision.

Why Should You Use Flux Core Welding?
Flux core welding, also known as Flux Core Arc Welding (FCAW), is indeed very similar to MIG welding, which is also known as Gas Metal Arc Welding (GMAW). Both methods involve welding through an arc formed between the electrode wire and the target metal, resulting in a strong and solid bond.
The main difference between FCAW and MIG welding lies in the use of shielding gas. MIG welding uses an inert blend of gases to protect the electrode from contamination and ensure a clean finish. This gas is supplied from a tank, making the MIG setup more complex and challenging to use, as well as more costly.
On the other hand, a flux core welder is more straightforward and convenient to use because it does not require external shielding gas. Instead, it uses the flux from the electrode wire to generate the necessary gases, covering the weld and protecting it from contamination. This eliminates the need for gas bottles and makes the setup more cost-effective and user-friendly.
The advantages of flux core welding, such as its simplicity and cost-effectiveness, make it an appealing choice for many welders, both professionals seeking high productivity and amateurs welding as a hobby. In essence, flux core welding is very similar to MIG welding, with the primary difference being the use of flux to create the required gases instead of relying on external gas connections.

Are They Good For Beginner Welding at Home
Flux core welders are popular in the home use market because of their affordability and convenience, especially for people who don’t weld on a daily basis. These machines are designed with lighter specifications and are not suitable for heavy-duty applications. As a result, their duty cycle, which refers to the percentage of time a welder can operate continuously without overheating, is often lower, typically ranging from twenty to thirty percent. While they may not meet the demands of professional welding, they are a practical choice for home users.
Flux core welding offers certain advantages over MIG setups. It provides a higher penetration factor, which means it can achieve deeper welds compared to MIG welding. Additionally, flux core welders do not always require external shielding gas, making them suitable for outdoor DIY projects where carrying gas bottles may be impractical. The continuous and consistent gas supply generated by the flux allows for high-speed welding. Moreover, the flux helps oxidize and remove impurities like rust, contributing to the welding process’s efficiency. Flux core welders are known for their fast electrode deposition rate, enabling faster completion of welding projects.
If you are a home user and need a cost-effective and efficient welding solution, a flux core welder could be a suitable choice for your needs. It provides good penetration, works well outdoors, and handles dirty metals effectively, all while being more budget-friendly than expensive MIG setups.
