Description

GEMINI 680 is a high-performance stainless steel welding electrode developed for welding dissimilar steels and materials that are difficult to weld. Engineered for demanding industrial applications, it provides excellent weld strength, stable arc characteristics, and dependable welding performance across a wide range of steel grades.

The electrode is particularly suitable for welding high nickel alloys without becoming fully austenitic due to nickel pick-up, making it ideal for maintenance, repair, fabrication, and heat-resisting steel applications. Its reliable mechanical properties and crack-resistant weld structure help ensure strong and durable weld joints in critical environments.

GEMINI 680 delivers smooth welding performance with consistent weld quality, making it suitable for industrial fabrication, repair work, and specialized stainless steel applications. The product complies with AWS SFA5.4 E312-16 classification standards and is approved under Thai Industrial Standard (TIS) 730-2558.
