E70T-3 and E70T-10 are examples of which welding electrode category?

Explanation:
These are flux-cored arc welding electrodes (FCAW). The E indicates an electrode, the 70 denotes about 70 ksi tensile strength, and the T shows a tubular, flux-cored electrode. The dash-suffix numbers describe shielding conditions and other properties, with some variants using external shielding gas and others being self-shielded. Because the electrode is a hollow wire filled with flux, designed for FCAW, they belong to the flux-cored category rather than SMAW (stick), GMAW (solid or coreless MIG), or GTAW (TIG).
