Exaton 19.9.LSi (GTAW)

Exaton 19.9.LSi GTAW is used for joining stainless steels of the 18Cr/8Ni ELC-type and 18Cr/8Ni/Nb type for service temperatures up to 350°C (660°F). It is also used for overlay welding.

Key Features

• Designed for SAW stainless steel welding in heavy‑duty environments
• Consistent wire chemistry and mechanical properties batch‑to‑batch
• High corrosion‑resistant chemistry with increased Cr and Mo
• Low‑moisture steel drum packaging (20‑25 kg drums)
• ESW flux provides higher speed and reduced cladding layers, lowering operating costs
