The numbers on flux core welding wire indicate the wire's classification, such as its tensile strength, welding position suitability, and type of flux. For example, in "E71T-1," "E" stands for electrode, "71" means 71,000 psi tensile strength, "T" means tubular (flux-cored), and the last number indicates the welding position and usability characteristics. These numbers help welders choose the right wire for their specific application.
