Yaskawa Motoman AR900

Yaskawa's Motoman AR900 is a compact six-axis arc welding arm, carrying a 7 kg payload across 927 mm of reach. The 34 kg arm is built for tight work cells and short welds, the spot where a bigger robot would crowd the torch and fixture. That compact envelope is the whole point of the model.

The AR900 supports Floor, Ceiling, Wall, and Tilt mounting, so integrators can orient it to suit whatever space the cell leaves. Overhead and wall positions help when the floor is already crowded with fixtures. Its short reach defines a modest work envelope matched to smaller parts and short welds.

The AR900's hollow wrist keeps the torch cable dress protected, which the record calls out as a headline strength for crowded weld cells. Dependable arc starts with Yaskawa's welding packages round out its case for short-run welding. Both points aim at the same goal: keeping a compact arm welding cleanly in a tight fixture.

The arm runs on Yaskawa's YRC1000 controller and carries an IP67 rating, and it reached the market in 2019. Its six axes hold torch orientation through a seam, the core motion an arc welder repeats all shift.

Teams weighing alternatives can compare Yaskawa AR2010 and KUKA KR 16 R2010. The short reach keeps the AR900 on smaller parts and fixtures, and the record notes it isn't built for heavy handling duty. Read those limits as scope rather than flaws: this is a welding specialist, not a general handler.

Where the AR900 stands out is precision: it holds repeatability to 0.03 mm, tight enough to drop a torch onto the same seam pass after pass.
