The SA12/2000H is a high-performance 6-axis industrial welding robot from STEP, specifically designed for automated welding of medium-to-large workpieces.
With a compact and agile design that supports full-position installation, it is ideal for automated production lines in industries including steel structure fabrication, construction machinery, shipbuilding, and automotive parts manufacturing.
Its large-aperture hollow wrist design minimizes interference with built-in welding torch cables, significantly extending cable service life and reducing maintenance costs. Boasting an ultra-high repeat positioning accuracy of ±0.03mm and a maximum end linear speed of 2.5m/s, it delivers both precision and efficiency.
Equipped with full-parameter compensation and a high-order dynamic algorithm, it effectively improves motion trajectory accuracy to ensure consistent welding quality. The robust gear transmission structure provides excellent impact resistance, making it suitable for complex and harsh working environments.
Supporting multiple industrial communication protocols, it features easy integration and simple operation, making it the perfect choice for automated welding of medium-to-large workpieces.
