Arc Welding Robot Manipulator


Extended Reach Through-Arm Cable Arc Welding Robot


For extended reach with a through-arm, the FD-B6L is your best-in-class solution from Daihen. Similar to its sibling robot, the FD-B6, the through-arm coaxial cable design of the FD-B6L gives you maximum mobility in tight workspaces. The FD-B6L makes welding large pieces in confined spaces or complicated fixtures a snap.

For large parts and fixtures, the FD-B6L’s streamlined coaxial cable improves wire feeding, giving you better overall weld quality.
