What is it?
The OTC Daihen FD-B4 is the smallest robot in OTC's FD welding series, optimised for short-reach precision arc welding in confined workspaces. It is designed to be integrated directly with OTC's welding power sources for a fully matched welding system.
Who is it for?
Sheet metal fabricators, electronics enclosure manufacturers, and precision component welders requiring a compact arc welding robot for short-reach, thin-material applications. Integrators building compact welding cells where access and minimal footprint matter.

FAQ
What welding processes does the FD-B4 support?
The FD-B4 supports MIG, MAG, and TIG arc welding processes when paired with compatible OTC Daihen welding power sources.
Why is the FD-B4's reach so short at 551mm?
The FD-B4 is designed for confined workspace welding where a compact robot arm is needed to access tight geometries — thin-material components, small enclosures, and precision fabrication fixtures that larger welding robots cannot reach.
What controller does the OTC FD-B4 use?
The FD-B4 uses OTC Daihen's AX controller, which provides integrated welding process control and motion programming.
