Which FCAW electrode is metal cored?

Explanation:
In flux-cored arc welding, a metal-core electrode is identified by an M in its designation. That M means the core inside the flux is metal, not just flux material. Metal-core wires are designed to deposit more metal quickly and produce stable, smooth beads on carbon steel, which makes them a popular choice for production welding and higher deposition tasks. Among the options, the electrode carrying the metal-core designation is the one that uses a metal tube core inside the flux. The other options are traditional shielded-metal-arc (stick) electrodes or other alloys that do not have a metal-core design.
