This product is a self-shielded flux-cored welding wire designed for MIG welding machines. It is specifically used for welding carbon steel (mild steel).
Unlike solid welding wire, it does not require an external shielding gas cylinder (like Argon or CO2). Instead, the wire has a core filled with flux compound that melts during welding. This chemical reaction creates its own protective gas shield and slag to keep the weld pool clean and free from contamination.
