Long-Reach Precision Arc Manipulator OTC DAIHEN® Automation

OTC DAIHEN FD-V8L – Extended Long-Reach 6-Axis Industrial Arc Welding Robot

8 kg Wrist Payload • 2,006mm Extended Horizontal Reach • Through-Arm Coaxial Cable Design

The OTC DAIHEN FD-V8L is an advanced long-reach variant of the high-performance 6-axis industrial robotic arm family, specifically optimized for high-precision arc welding operations and extended material handling across expansive work envelopes. Built with a specialized elongated structural profile, the FD-V8L delivers a vast horizontal reach of 2,006 mm, enabling it to access hard-to-reach seams, handle wide workpieces, and operate smoothly over large, complex fixtures. By routing the welding torch's coaxial cables directly through the center of the upper arm axis, this through-arm design minimizes structural whipping, eliminates external utility snags, and prevents torch cable interference during complicated multi-angle motion profiles. Running on synchronized high-speed digital drives, it effectively slashes production cycle times while providing superior weld bead consistency for demanding high-density manufacturing systems.

Key Features & Design Advantages

Extended 2.0-Meter Working Range
Features a broad horizontal reach of 2,006 mm, significantly expanding the workspace envelope and reducing the need for expensive multi-axis external positioners.
Through-Arm Cable Protection
Integrated coaxial cable routing guides essential torch lines through the hollow arm structure, shielding them from abrasive mechanical wear and simplifying manual software teaching.
High Precision Repeatability
Maintains an exceptional positional repeatability rating of ±0.08 mm, securing consistent track tracking for clean, spatter-free weld finishes.
Dual Load Support Capacity
Accommodates an 8 kg payload on the main wrist alongside a separate 10 kg auxiliary equipment load capacity on Axis 3 to easily carry wire feeders or vision hardware.

Target Applications

• Extended-Reach Arc Welding: Optimized for high-speed MIG, TIG, and CO2 processes on oversized sub-assemblies and large metal plates.
• Large Area Material Handling: Manages component loads up to 8 kg over large distances, streamlining part sorting and palletizing loops.
• Multi-Station Machine Tending: Reaches multiple manufacturing jigs or workstations sequentially from a single fixed mounting spot.

System Benefits

✓ High joint velocities speed up motion tracking paths, shrinking takt times to maximize plant productivity.
✓ The hollow wrist design allows smooth wire feed action, ensuring exceptional weld profile uniformity.
✓ Slim structural architecture allows trouble-free configuration inside restricted workspaces next to adjacent cells.
