StarBlaze Prime 7024SS
AWS A5.1: E7024 | ISO 2560-A: E 42 0 RR 73
180% Recovery | Workshop Fillet Specialist | Ultra-Smooth, Flat-Only Fusion
A rutile-coated iron powder electrode engineered for maximum deposition rates—offering up to 180% weld metal recovery. Designed for high-efficiency fillet and butt welds in the flat and horizontal positions, it delivers soft arc transfer, fine ripple bead formation, and virtually spatter-free operation. Perfect for tank fabrication, structural platforms, and bridge girder assembly.
