OTC DAIHEN FD-V8L Long-Arm Welding Robot

FD-V8L is the extended-reach version of OTC DAIHEN’s popular FD-V8 series, offering a 2.0m working radius while maintaining 8kg payload and ±0.08mm repeatability. Designed for large-scale fabrication, it combines industry-leading speed with a ultra-slim arm and fully internal cabling.

✨ Key Technology Advantages

2.0m extra-long reach — Covers larger workspaces, reduces repositioning, ideal for large structures.
Industry-leading speed — J6 max. 630°/s, significantly cuts cycle time.
Ultra-slim arm design — Optimized basic axes and return radius, perfect for confined areas.
Synchro-feed fully internal cabling — All welding cables routed inside the arm, zero rear interference, clean cable management.
High payload capacity — 8kg wrist load (30% increase), upper arm payload up to 20kg.
High-power drive — 5000W drive capacity for demanding applications.
Flexible mounting — Floor, ceiling, side wall installation.

🔧 Primary Applications
