StarBlaze Prime 7024S
AWS A5.1: E7024 | ISO 2560-A: E 42 0 RR 73 | EN 499: E 42 0 RR 73
165% Recovery | Heavy Plate Build-Up | Soft Arc, Low Spatter
A rutile-based heavy-coated iron powder electrode engineered for maximum deposition efficiency in flat and horizontal fillet welding. With an output recovery of ~165%, STARBLAZE 7024S offers smooth bead profiles, soft arc fusion, and minimal slag cleanup—ideal for high-speed welding of tanks, platforms, and other large structural assemblies. Excellent for long weld passes on thick materials where high productivity is critical.
