A flux core welder is a type of welding machine that uses a wire electrode that is fed through the center of a hollow, tubular wire. The electrode and the filler metal are combined in an electric arc to create heat, which melts the metals and joins them together. Flux core welding is a popular welding process that is used in a wide range of industries. 

This welding process uses a wire that is coated with flux. The flux helps to create a shield around the weld area, which protects the weld from contamination. This type of welding can be performed with either an automatic or semi-automatic welder. 

Another advantage to the flux-core welder is its portability. This welder can be taken almost anywhere because it doesn’t require a large power source or gas tanks.

We’ll take you through each welder’s key features, what they’re best for, and how they compare to other models on the market. By the end of this guide, you’ll have all the information you need to make an informed decision about which flux core welder is right for you.
