Motoman Arc Welding Robots

Motoman MA-series arc welding robot

Yaskawa Motoman continues to lead welding robot design innovation, with industry-first features that make Motoman welding robots the preferred choice for precision, durability and flexibility.

The integrated through-the-arm cabling in the MA-series robots improves weld accuracy, torch access and uptime.  Yaskawa Motoman backs the performance of the MA-series arc welding robots with the industry’s first two-year torch cable warranty.  Yaskawa Motoman offers extended-reach (>3.0-m) welding robotis including the MA3120. and MA50-20 models.

The first 7-axis robotic welder

In response to customers’ needs for more efficient space utilization, Yaskawa Motoman developed the first 7-axis robot welder – the VA1400. The flexibility of the Motoman VA series arc welding robot reduces floor space and accommodates multiple welding robots in a single cell. The unique “elbow” axis of the welding arm reaches around tall parts, into boxy parts, and other places an external axis would normally be needed.

Motoman Spot Welding Robots

Motoman MS210 spot welding robot with external cablingYaskawa Motoman innovations in the robotic spot welding market include ES-series “Expert Spot” robots with an integrated spot harness.  With spot utilities (power, water, air, motor and signal lines) integrated into the profile of the robot arm, automotive OEMs and Tier 1 suppliers realize increased flexibility and higher uptime.  Motoman’s patented multiple robot control technology allows close interaction of several arms working on a car body without fear of collision.

Motoman’s latest innovation is the VS100 spot welding robot.  This 7-axis spot welding robot is designed to take full advantage of proven Direct Current (DC) weld timers and servo controlled actuators, Motoman is introducing a series of light weight “mini-guns.”  These powerful, compact spot guns weigh less than 50 kg, but deliver high performance with 600 kgf clamping pressure and 15,000 Amps of welding current.  The low profile and “elbow” on the VS100 robot allow it to be positioned close to the vehicle.  It can reach underneath or inside confined spaces.

The 6-axis MS80 robot has a slim profile and longer reach for windshields and pillars.  These smaller, faster spot welding robots are designed to be used with full-size ES165D/ES200D model with larger guns to maximize robot density in a welding station.  This “high-density” approach reduces takt time and shortens the production line with fewer re-spot stations.
