The WIA Austarc 77 E7018 Electrode – 77/25 delivers reliable welding performance for structural fabrication, repair, and maintenance applications. Designed as a low hydrogen iron powder electrode, it provides excellent weld strength, smooth arc stability, and high-quality weld appearance. The 2.5mm electrode size offers excellent control for light to medium fabrication work.
Austarc 77 electrodes produce a smooth and stable arc with low spatter levels during operation. Excellent edge wetting helps reduce undercut while improving weld appearance and slag removal. The smooth running characteristics also support easy striking and reliable restriking for improved productivity on the job.
These E7018 electrodes suit critical welding tasks involving structural steel, pressure vessels, heavy machinery, mining equipment, and maintenance work. The low hydrogen formulation helps minimise the risk of hydrogen cracking while delivering high ductility and strong impact resistance. Welds achieve x-ray quality performance with excellent toughness at temperatures down to -50°C.
The Austarc 77 supports all positional welding except vertical down applications. It operates effectively on both AC and DC welding machines, making it suitable for workshop and on-site welding environments. The stable arc and fluid slag system also improve control during vertical-up welding tasks.
Manufactured by WIA, the Austarc 77 range has built a strong reputation for consistent weld quality and dependable performance across demanding industrial applications. Professional welders value these electrodes for their smooth operation, excellent mechanical properties, and reliable low hydrogen performance.
