Components of a Yaskawa Motoman Welding System

Welding automation often involves using industrial robots to convert a manual welding application into an automatic one. Robotic welding systems have grown in use over the years due to their numerous benefits and the current welder shortage. Yaskawa Motoman has been automating welding applications for over three decades. Their robotic welding systems typically consist of an industrial robot, welding equipment, and a workcell.


The welding robot is one of the main components of any Yaskawa Motoman welding system. Yaskawa Motoman produces robots capable of automating arc welding and spot welding applications, but they are most well-known for their arc welding robots. A Yaskawa Motoman welding system may consist of one or multiple articulated robots depending upon the desired product volume and productivity levels.

A Yaskawa Motoman robotic welding system for arc welding automation will typically consist of a six axis robot or robots from one of their arc welding lines. These include their “Expert Arc” (EA), “Master Arc” (MA), “Versatile Arc” (VA), and “Super Speed Arc” (SSA) series. All Yaskawa Motoman arc welding robots are designed for fast, accurate, and precise operation. The Yaskawa MA1440 and EA1900N are two of their most popular arc welding robots. Yaskawa Motoman’s arc welding robots also feature slender arms/wrists and internal cabling for the most reliable welding.

Robots from Yaskawa Motoman’s ES “Expert Spot” series are designed for spot welding automation. The Motoman ES165D-100 is ideal for integration with a spot welding system as it features a high payload and extended reach for operating heavy tooling in addition to working with large workpieces. Yaskawa Motoman’s spot welding robots feature more compact footprints with collision detection technology making the integration of multiple robots in a spot welding system possible.

Welding Equipment

The welding equipment integrated with a Yaskawa Motoman welding system will vary based upon the exact type of welding application. In general, some of the equipment you can expect includes the EOAT, power supply, positioner, wire feeder, and reamer. For arc welding applications robots will be integrated with either an air-cooled or water-cooled torch for the EOAT. While spot welding robots are integrated with a welding gun for tooling.

A power supply is another component of an arc welding system. Power supplies from both Fronius and Miller Electric are often integrated with Yaskawa Motoman robots. The Miller Auto Continuum 350 is compatible with the Motoman MA1400. A wire feeder may also be needed for arc welding if the application requires filler wire. These can be integrated on the back of the arm of Yaskawa Motoman robots. Positioners are needed to rotate workpieces for Yaskawa Motoman robots during welding. A reamer can be integrated in a Yaskawa Motoman arc welding system to automatically clean the weld torch, preventing spatter buildup.

Weld Cell

For arc welding applications, all welding components can be integrated with a weld cell for a more efficient and optimized operation. Yaskawa Motoman manufacturers their own turnkey cells in their ArcWorld series. These pre-engineered cells include all components needed for an arc welding application, easing the implementation and integration of a Yaskawa Motoman welding system.
