Used Motoman SP225H Hollow‑Arm Spot Welding Robot, 225kg Payload 2702mm 6‑Axis Floor‑Mount Robot

Extra Information:

This used Motoman SP225H is a floor-mount six-axis hollow-arm spot welding robot. It delivers 225 kg payload and 2702 mm horizontal reach, engineered for ultra-heavy-duty spot welding tasks within automotive body assembly workshops.
The hollow-arm internal cable routing fully accommodates spot welding harness, effectively preventing cable twisting, scratching and hooking during complex multi-angle posture adjustment, and lowers mechanical interference with surrounding fixtures and workpieces. Slim-structured arm enables access to narrow-gap working positions and supports high-density multi-robot layout inside welding cells. The wrist features large rotation angle coverage, offering abundant attitude adjustment range for heavy-weight spot welding guns.
Driven by Sigma-7 servo system and paired with YRC1000 controller, the robot maintains powerful dynamic output under full-payload continuous cyclic operation, keeping stable repeat positioning accuracy over long production cycles. Besides spot-welding applications, it can perform heavy-duty material transfer within its payload limit, widely deployed for high-intensity automated welding production lines for vehicle bodies and large structural components
