Fairino Ultra Lightweight Collaborative Manufacturing And Welding Robot (FR3(WML))

Fairino Ultra Lightweight Collaborative Manufacturing And Welding Robot (FR3(WML))

Within the FAIRINO FR-series ecosystem, the FR3 platform is generally presented as a 6-DOF collaborative arm with a 3 kg nominal payload, 622 mm reach, and ±0.02 mm pose repeatability (ISO 9283). The FR3(WML) variant is specifically associated with welding-oriented features—most notably extended wrist rotation (±360° on the final axis) to support curved and wrap-around weld paths (for example, pipes and complex shapes).

Design and Features

Ultra-lightweight, portable collaborative arm

Open listings describe FR3(WML) as ultra-lightweight and suitable for single-person handling in compact deployments, emphasizing portability for production cells that must be moved or reconfigured.
The underlying FR3 platform is also described as a collaborative robot intended for flexible “human–robot collaboration” applications across multiple industries.

Six-axis kinematics optimized for welding access

FR3(WML) is presented as a 6-axis cobot designed to combine manufacturing tasks (pick-and-place, tending, light assembly) with welding workflows.
A key differentiator highlighted in multiple sources is full continuous-style wrist rotation on the sixth axis (±360°), enabling tool orientation around cylindrical parts and curved surfaces with fewer repositioning steps.

Collaborative operation and safety-oriented behavior

FR3(WML) is marketed as supporting safe collaboration, with listings explicitly mentioning collision-related safety for human–robot collaboration.
The general FR3 specification pages frame the platform as a collaborative robot designed for shared workspaces and rapid deployment through intuitive programming methods.

FR3(WML) variant characteristics relevant to welding

For FR3(WML), public catalog descriptions emphasize:

• Ultra-lightweight design aimed at easy handling and flexible manufacturing layouts

• High-precision welding positioning paired with collaborative safety claims (collision-related protections)

• ±360° sixth-axis rotation to support curved-surface and pipe welding with fewer compromises in torch orientation

• Published baseline figures in some listings: payload 3 kg, reach 622 mm, repeatability ±0.02 mm

Applications and Use Cases

Collaborative welding and flexible fabrication

FR3(WML) is explicitly positioned for welding tasks, including complex geometries where extended wrist rotation can reduce the need to reposition the workpiece. Typical cobot-welding deployments include:

• TIG/MIG process cells for light-gauge parts

• Small-batch fabrication where programming speed matters

• Pipe or curved-surface welding where tool orientation is constrained

Multi-purpose manufacturing cells

The FR3 family is also described for broader flexible manufacturing scenarios—such as light handling and production support—often cited across electronics/3C, metal processing, and gluing applications in general FR3 descriptions.

Education, prototyping, and integrator development

Where supported, SDK references (C#/C++/Python and ROS/ROS 2) position the platform for integrators and R&D teams building custom applications, including machine vision, path planning, or process monitoring.

Advantages / Benefits

Mobility of deployment in real production environments

An “ultra-lightweight” positioning supports rapid redeployment: moving a cobot between benches or cells can reduce downtime in facilities that run variable product mixes.

Welding access via extended wrist rotation

The frequently cited ±360° sixth-axis capability is a practical advantage for weld paths around cylindrical parts and complex shapes, helping maintain torch angles and travel directions without excessive re-fixturing.

Collaborative design with industrial connectivity

The FR3 platform’s published specs include IP54 (optional IP65) and industrial I/O and networking options, which matter for production integration and shop-floor robustness.
