  • FD-B4L


  • FD-B4L by extending the range of the arm, P point movement range of up to 2008mm
  • It can be applied to a relatively large range of operation
  • Long arm structure, higher operating efficiency
  • Coaxial cable built structure, to minimize interference between cables and clamps, easier access to weld attitude
  • Applied to arc welding, spot welding, cutting, gluing, handling and other functions in the field, able to cope with the production and processing of various requirements
