Advantages and Disadvantages of Metal Cored Wires

In those days, the 3/32” (2.4 mm) diameter was a “small diameter” flux cored wire. Flux cored wires provided better metal penetration, smoother arc transfers, lower spatter levels and were overall easier to use than solid MIG wires, but they were limited to flat and horizontal positions and the equipment to use them was heavy and cuersome.
