Flux Cored Self Shielded Wire

Flux Cored Self Shielded Wire

Why Flux Core Self Shielded Wire?  This flux core wire (FCAW) is a wire feed process but differs in that self-shielded flux cored welding does not require a shielding gas. The flux contains ingredients to generate its own shielding gas for protecting the arc. This type of flux core welding is attractive because it is portable and generally has good penetration into the base metal.
