Similar to MIG, flux-cored arc welding (FCAW)* is a wire-feed process but differs in that self-shielded FCAW does not require shielding gas. Instead, flux-cored wire shields the arc from contamination. This is a simple and efficient approach, especially when welding outdoors, in windy conditions or on dirty materials. FCAW is widely used in construction because of its high welding speed and portability.
MIG and flux-cored welding are easy to learn and can create extremely clean welds on steel, aluminum and stainless. Both processes have the capability to weld materials as thin as 26 gauge.
