Product Specification

Long-Reach Collaborative Welding Robot OTC DAIHEN® Cobot Series

OTC FD-VC4L – Long-Reach Collaborative Welding Robot

Extended Operational Reach • High Precision • Safe Human-Robot Collaboration

The OTC FD-VC4L is an extended-arm collaborative welding robot precision-engineered to deliver maximum safety, operational flexibility, and high-tier repeatability. Featuring a sleek, slim, and rounded chassis configuration, it enables seamless human-robot workplace interaction without demanding bulky perimeter safety guards, maximizing workspace utility while safeguarding production personnel.

Design & Welding Automation

Extended Workspace Flexibility: Its extended 1,317 mm reach offers wide articulation freedom, making it easy to cover multi-position fixture layouts or larger assemblies. Weighing only 37 kg, it delivers swift factory-floor redeployment capabilities.

Premium Arc Stability: Fully compatible with digital OTC Daihen power sources, it utilizes advanced motion tracking matrices to support high-speed CO₂/MAG, TIG, and proprietary low-spatter wave processes with uniform seam results.

Certified Safety & Ease of Use

Built in absolute accordance with rigorous ISO 10218-1 and ISO 13849-1 PLd Cat. 3 industrial regulations, the FD-VC4L is outfitted with torque-monitoring sensors that instantly trigger automatic stops upon encountering abnormal external force resistances.

Intuitive PhotoTeach Programming: Operators can bypass legacy code scripting by manually hand-guiding the robot arm into position or utilizing tablet-based visual applications to set up multi-axis welding trajectories instantly.

Key Features

  • Extended Reach: Generous 1,317 mm arm span engineered to manage complex, wide structural assemblies.
  • Lightweight Design: Highly agile 37 kg footprint for effortless job-cell relocation.
  • Uncompromising Accuracy: Exceptionally tight ±0.02 mm path repeatability ensures professional weld fusion.
  • Certified Cobot Protections: Out-of-the-box compliance with international ISO safety frameworks.
  • User-Friendly Interfacing: Direct support for fluid hand-guided teaching arrays.
  • IP65 Rated Architecture: Durable exterior shell seals away heavy factory dust, airborne sparks, and harsh gas fumes.
