Overview • The SA6-1440H 6kg Payload 1440mm Welding Robot Arm Multi Pass Arc Tracking Cell is configured for thicker sections that need several weld runs on the same joint. • A 1440mm reach covers a fixture table plus the weld zone, and the hollow wrist keeps the torch cable clear when the torch rotates for vertical and overhead passes. • The arc tracking function follows gap and mismatch variation along the joint, which matters when fit up quality changes between parts. •
