KUKA KR 210 R2700 (Quantec)

The KUKA KR 210 R2700 is a heavy six-axis arm from the Quantec line, built for the body-shop end of automotive work. It carries a 210 kg payload out to a 2696 mm reach, so full weld guns and large fixtures stay inside a wide work-envelope. That reach and payload are what put it on spot-welding and heavy-handling stations.

Repeatability of 0.06 mm keeps a heavy tool landing on the same taught point across long production runs. For a station that welds the same joints thousands of times, that repeatability is what holds part quality steady. It has to hold at full extension too, where the payload sits farthest from the base.

At 1068 kg the arm is a large, heavy machine, and the record flags that size as a consideration. It mounts to the floor, so you'll want a rigid, level base and a cell laid out around its footprint. Get the foundation and leveling right before the first fixture arrives.

The KR C4 controller runs the arm, and the body is rated IP65. Continuous-duty construction suits stations that run welding across multiple shifts without long gaps. Size the payload-inertia of the weld tooling into the load setup before the station goes live.

Beyond welding, the 210 kg payload gives headroom for heavy material-handling, moving stampings, castings, or full sub-assemblies between stations. A tool-changer lets one arm swap between a weld gun and a handling gripper as the line reconfigures. Plan the dress-pack routing so cabling clears the fixtures through the full envelope.

Day to day, the listed work stays on spot-welding and heavy handling. At this payload class, a preventive-maintenance rhythm on the reducers and grease points keeps a heavy welding cell running. Watch reducer-wear and hold to the grease-interval as part of that upkeep.
