Self-Shielded vs. Gas-Shielded Flux-Cored Electrodes

All flux-cored wires have some similar characteristics. These include forming a protective slag over the weld, use a drag angle technique, have the ability to weld out-of-position or flat and horizontal only at higher deposition rates (depending on type of wire), ability to handle contaminants on the plate, etc. However, there are two fundamentally different types of flux-cored wires. One type is self-shielded and the other type is gas-shielded.
