Easy-to-Teach and Easy-to-Operate
Arc Welding Robot—Satisfies User’s Needs
              for Saving Space and High Productivity
Arc-Js robot, especially developed for arc welding, incorporates   allows flexibility in the robot’s mounting posture with a large
Kawasaki’s latest technology to meet user needs. Unskilled         working envelope and saves mounting space. Arc-Js’s fast
workers can teach and operate the robot easily, solving the        processing speed considerably reduces air-cut time, resulting in
problem of a shortage of skilled workers. The compact arm          high productivity.
    Features
1. High quality welding                                            3. Flexible mounting
A smooth and accurate focus can be achieved thanks to              The compact arm without dead angles only requires a small
the high resolution position encoders, low-ripple, sine-wave AC    apace for mounting. Floor, ceiling, balcony or wall-hanging
servomotors, high-precision low-ripple reduction units and         mounting is possible, depending on the user’s production
various software servo functions. thus, high quality welding is    facilities. Its large working envelope also provides easy
achieved.                                                          continuous circumferential welding.
2. Reduced cycle time
The maximum tool tip speed of 4 meters/sec and a tool posture
changing speed of 600 degrees/sec in the air-cut motion
provide a high performance welding robot. Consequently, the
work cycle time can be reduced considerably
