The MOTOMAN AR3120: The Ultra-Long Arm Welding Powerhouse

When it comes to tackling large, flat, or deep workpieces, the MOTOMAN AR3120 is your go-to robot. This six-axis, ultra-long arm welding robot has a reach of over 3 metres, making it perfect for those massive jobs that demand precision and efficiency. 

Whether you’re welding or cutting, the AR3120 combines cutting-edge technology with a design that minimises interference and maximises performance. 

Let’s dive into why this robot is a game-changer for arc welding.

Built for the Big Jobs

The AR3120’s biggest asset is its ultra-long reach. With a motion range of 3124 mm, it can handle those bulky, awkwardly shaped workpieces that most robots struggle with. 

Whether it's large panels or deep-set pieces, the AR3120 can cover all that ground with ease. Plus, it has a payload of up to 20 kg, meaning it can handle heavy-duty welding guns without breaking a sweat.

Precision Meets Power

One of the standout features of the AR3120 is its high path accuracy. You can trust it to deliver precise, consistent welds, even in tricky conditions. 

It’s powered by the YRC1000 controller, which makes programming a breeze and ensures you’re getting the most out of the robot’s capabilities. Whether you're a seasoned pro or new to automation, the AR3120’s ease of use will impress.

Designed to Avoid Hassles

Ever worried about cables getting in the way during a job? The hollow arm design of the AR3120 solves that problem by allowing the welding cables and wire feeder to run through the robot’s arm. 

This smart design not only keeps things tidy but also avoids collisions and interference with jigs and fixtures. The slightly bowed arm structure further reduces the interference area, giving you more freedom to work without worrying about the robot getting in the way.

Cutting-Edge Welding Technology

The AR3120 isn’t just about reach—it’s packed with features that make it a top choice for arc welding. For instance, the wire feeder can be mounted at axis 3, keeping the welding wire supply close and efficient. 

Plus, YASKAWA’s Multi-Robot technology allows you to synchronise up to 8 robots (or 72 axes) with a single controller, making large-scale operations smoother than ever.

Why Choose the MOTOMAN AR3120?

• Massive Reach: With a 3.1m working range, this robot can handle the largest workpieces with ease.

• Precision Welding: Its high path accuracy ensures clean, consistent welds every time.

• User-Friendly: Easy programming and control make it accessible for operators at all levels.

• Less Interference: The smart arm design minimises interference and keeps cables neatly tucked away.

• High-Speed Performance: With speeds up to 630°/s on its axes, the AR3120 isn’t just powerful—it’s fast.

Flexibility and Efficiency

One of the AR3120’s biggest strengths is its flexibility. You can mount it on the ceiling, wall, or floor—whatever works best for your setup. 

Plus, its streamlined design means it can fit into tight spots, working in high-density environments where other robots might struggle. 

And with the option for jigless welding, the AR3120 offers a level of flexibility that makes it adaptable to a wide range of applications.

Ready to Boost Your Productivity?

If you’re looking for a reliable, efficient, and versatile welding robot that can handle the big jobs with precision, the MOTOMAN AR3120 is hard to beat. 

It’s got the reach, power, and technology to take your welding operations to the next level, all while being easy to use and maintain. 

In the world of arc welding, size definitely matters—and the AR3120 is here to prove it.
