OTC DAIHEN FD 6-Axis Robots Review: Specs and Uses of the 5 to 130 kg Welding and Handling Lineup
Updated: 7 days ago
OTC DAIHEN builds 6-axis industrial robots mainly for arc welding, along with cutting and material handling. The manufacturer does not publish a price. This review covers its specifications, features and uses.
Quick Verdict
The FD 6-axis lineup runs from the compact FD-H5 with 5 kg and 866 mm reach to the FD-V130 with 130 kg. Welding is the focus: the FD-B6 and FD-B6L have a hollow, through-arm design that routes the torch cable inside the arm, and the V-series models add arc, TIG, plasma cutting and handling. Series II versions of the B6L, V8L and V25 run on the FD-21 controller and, according to DAIHEN, are 13% lighter, up to 15 to 42% faster and 38 to 43% more repeatable than their predecessors. The US page does not give absolute repeatability or arm weights, which limits direct comparison.
