StarBlaze Prime 7010G
AWS A5.5: E7010-G | EN ISO 2560-A: E 42 3 C 21
High Penetration | All Position Use | Minimal Re-drying Requirement
A cellulosic-coated deep penetration electrode designed for welding high-strength pipelines and structural steels in all positions, including vertical-down using conventional and stove-pipe techniques. Provides a forceful arc, fast freezing slag, and excellent performance across root, fill, and cap passes. Commonly used in field welding with minimal need for electrode re-conditioning.
