Head to head
ABB IRB 6640 vs Kawasaki BX200L
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Heavy-payload foundry-proven material handler
Heavy arm dedicated to resistance spot welding
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The ABB IRB 6640 is a 6-axis industrial arm and the Kawasaki BX200L is a spot welding arm, so this comes down to which job you are building the cell around rather than a spec-for-spec race. They run different controllers, the ABB IRB 6640 on the IRC5 and the Kawasaki BX200L on the F02, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Both are aimed at material handling, with the ABB IRB 6640 stretching to machine tending and palletizing and the Kawasaki BX200L to spot welding.
