Flux-Core Arc Welders:

Flux-Core Arc Welders use a wire that, in its core, contains materials that release the shielding gases necessary to be able to protect the molten metal from the environment. There is no need concerning any external shielding agent, and also the shielding gases released by the wire can even withstand powerful breezes.

The drawback to the Flux-Core Arc Welders is that they use a fairly forceful arc, creating a large amount of spatter. Additionally, there can end up being slag on the final welding job, as well as it's going to end up being removed for a neat, clean finish. Extra disadvantages can appear as a result of mechanical troubles, like irregularity in the wire feeding. The filler material will be also a lot more costly than that compared to a Gas-Metal Welders.
