OTC DAIHEN FD-B6L Long-Arm Welding Robot

FD-B6L is the extended-reach version of OTC DAIHEN’s FD-B6 series, offering a 2.0m working radius while maintaining 6kg payload and ±0.08mm repeatability. Designed for large-scale fabrication, it features industry-leading speed, embedded J5/J6 motors, and fully internal Synchro-feed cabling for zero interference.

✨ 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.
Embedded J5/J6 motors — Motors completely hidden inside the arm, zero interference with fixtures or workpieces.
Synchro-feed fully internal cabling — All welding cables routed inside the robot body, clean and collision‑free rear area.
High payload capacity — 6kg wrist load, upper arm payload up to 20kg.
Flexible mounting — Floor, ceiling, side wall installation.

🔧 Primary Applications

Arc welding of large structural components, spot welding, material handling, machine tending, dispensing, cutting assistance, assembly. Perfectly pairs with OTC DAIHEN digital welding power sources for superior arc quality.
