Intelligent closed-loop wire feeding
High-frequency back electromotive force control ensures precise and consistent wire feeding even under varying load conditions, critical for maintaining weld quality in submerged arc applications.
Full-Digital Submerged Arc Welding Machine
SA Series
The Megmeet SA Series delivers industrial-grade submerged arc welding with output up to 1250A at 100% duty cycle. Featuring CC/CV modes, intelligent closed-loop wire feeding, and stable performance at 100m cable extension, it is built for the most demanding heavy fabrication environments.
Up to 1250A output
Available in 1000A and 1250A variants, both rated at 100% duty cycle for uninterrupted high-deposition welding on heavy steel structures.
CC/CV welding modes
Constant current and constant voltage welding modes provide flexibility for different joint configurations and wire types in submerged arc applications.
100m cable stability
Maintains stable welding performance with cable extended to 100 meters, essential for large-scale shipbuilding, bridge, and structural steel fabrication.
