Used KUKA KR5 Compact Welding Robot Arm (5kg Payload, 1400mm Reach) with KRC2 Controller

Minimal Interference Contours for Tight Workcells: High Precision with Zero Capex Waste

Deploying robotic arc welding or precision machine tending in crowded workshop floors often poses space constraints, where standard robotic arms collide with fixtures or adjacent CNC machines. The KUKA KR5 (including KR 5 arc series) provides an ultra-compact solution: with an exceptionally small footprint of only 324 × 324 mm and weighing just 127 kg, it easily integrates into confined cells or mounts upside-down to cell gantry frames.

Handling a 5 kg rated payload across an agile 1,400 mm reach, the KR5 delivers high axis speeds (up to 721°/s on Axis 6) and a certified ±0.04 mm repeatability for consistent weld seam penetration. Every pre-owned KR5 unit in Pengju Robotics' inventory undergoes our standardized 45-Item Outgoing Inspection Protocol—checking harmonic gear backlash, verifying KRC2 electronic safety circuits, and running continuous multi-hour loop cycles before export packaging.
