Fairino FR3 Variants Explained: Standard vs. WMS vs. WML

Which Collaborative Robot Is Right for Your Operation?

The Fairino FR3 has established itself as one of the most affordable and versatile collaborative robots on the market. But if you've been researching recent product updates, you may have noticed there are actually three distinct variants to choose from: the standard FR3, the FR3(WMS), and the FR3(WML). Each is optimized for different workflows and precision requirements.

So which one should you add to your production line? Let's break down the differences.

Side-by-Side Comparison

Reach	~500 mm	622 mm	922 mm
Payload	3 kg	3 kg	3 kg
Repeatability	Standard	±0.02 mm	±0.05 mm
Weight	~11 kg	~10.5 kg	~11.25 kg
6th Axis Rotation	Standard	±360°	±360°
Welding-Optimized	No	Yes	Yes
Best For	General automation	Precision welding	Production welding & mfg

Standard FR3: General-Purpose Automation

The standard Fairino FR3 is the jack-of-all-trades. With a 500 mm reach and 3 kg payload, it's designed for the broadest range of collaborative tasks:

• Pick-and-place operations — moving components between workstations

• Basic assembly — inserting parts, fastening, light kitting

• Machine tending — loading and unloading CNC machines or injection molders

• Packaging and palletizing — organizing finished goods

  
  

Why choose it: If you're automating general factory tasks and don't have specialized precision or reach requirements, the standard FR3 is your most economical choice. It's easy to program, safe around human workers, and adaptable to a wide range of applications.

FR3 (WMS): Ultra-Precision Welding for Detail Work

The FR3 (WMS) (Welding, Manufacturing, Smaller) is built for intricate, high-tolerance welding and precision tasks. Its standout feature is exceptional accuracy: ±0.02 mm repeatability — nearly twice as precise as the WML.

Key specs:

• Reach: 622 mm (tight workspace? No problem)

• Wrist rotation: ±360° for complex weld angles

• Lightweight: 10.5 kg, easy for a single technician to reposition

  
  

Best applications:

• Fine welding work — medical devices, electronics enclosures, precision piping

• Intricate detail assembly — where tolerances matter

• High-precision manufacturing — aerospace or automotive sub-components

• Deburring and finishing — where precision prevents rework

  
  

Why choose it: If tight tolerances and flawless detail work are non-negotiable, the WMS's ultra-high precision (±0.02 mm) justifies the investment. It's ideal for makers who ship zero-defect products and can't afford rework.

FR3 (WML): Production Welding with Extended Reach

The FR3 (WML) (Welding, Manufacturing, Longer reach) bridges the gap between compact precision robots and large industrial arms. With a 922 mm reach, it accesses larger work envelopes while maintaining collaborative safety and affordability.

Key specs:

• Reach: 922 mm (50% longer than WMS)

• Repeatability: ±0.05 mm (precision + production speed balance)

• Wrist rotation: ±360° for curved and wrap-around welds

• IP54/IP65 protection — tolerates light splatter and workshop conditions

  
  

Best applications:

• Production-scale welding — complex curves, pipes, assembled frames

• Flexible manufacturing — easily reprogrammed between production runs

• High-volume small-batch automation — cost-effective scaling

• Welding, cutting, polishing, painting — versatile for multi-process cells

Why choose it: If you're automating a production line with moderate precision needs and larger workpieces (pipes, assemblies, complex geometries), the WML's extended reach lets you tackle jobs that would require a much larger (and more expensive) industrial robot. Perfect for small-to-mid-sized manufacturers ready to scale.

How to Choose

Pick the Standard FR3 if:

• You need general automation (picking, placing, assembly, tending)

• Budget is the primary constraint

• Your workpieces are small and workspace is compact

Pick the FR3 (WMS) if:

• Welding quality and precision are critical

• You're working in tight spaces or with intricate components

• Tolerances are tight (aerospace, medical, electronics)

• You can't afford rework due to dimensional errors

Pick the FR3 (WML) if:

• You're automating production-scale welding or multi-process manufacturing

• Your workpieces are larger or geometrically complex (pipes, frames, curves)

• You want flexible, reprogrammable automation for small-batch runs

• You need a cobot that scales with your business without a massive capital investment
