Welding Robots

7-Axis Robots

OTC DAIHEN offers an astounding five models of the 7-axis robot with many advanced capabilities and options for manufacturers. Our 7-axis robots have the ability to “lie down” and reach around parts and obstacles, ideal for applications where part positioning is not available. The 7-axis robot is also able to hold optimal torch angle and attitude on longer parts, without compromise.

OTC DAIHEN FD-B4S robot welder

FD-B4S 7-axis, Through-Arm, Welding Robot (4kg payload, 1.435m reach)

Our FD-B4S, 7-axis, through-arm, arc-welding robot is ideal for short and medium reach tight spaces with crowded welding zones. A through-arm design results in a slim manipulator without exterior cables or conduits to impede movement or snag in hard-to-reach or crowded areas.

  • Rotation of the 7th-axis enables interference avoidance without changing the position and/or attitude of the end-of-arm tool
  • Maintains the optimal angle and attitude of the end-of-arm tool at all times, resulting in enhanced weld quality and ease of programming
  • Offers a wide working range with an independently articulated arm
  • Seamless digital connection with all OTC DAIHEN brand welding power supplies
  • Improved vibration restraining control provides smooth robot movement
  • Built-in mechanical shock sensor
  • Single source technology – all components are manufactured by OTC DAIHEN
  • Highly versatile design supports most welding applications
OTC DAIHEN FD-V6S robot welder

FD-V6S 7-axis Robot (6kg payload, 1.427m reach)

Our FD-V6S 7-axis robot is suitable for arc-welding, air-plasma cutting and material-handling applications.  The additional payload supports additional arm attachments such as laser seam tracking or vision guidance cameras.

OTC DAIHEN FD-B4LS robot welder

FD-B4LS 7-axis, Through-Arm, Long-Reach, Welding Robot (4kg payload, 2.008m reach)

Our FD-B4LS 7-axis welding robot extends the reach of our B4S robot model while incorporating the same through-arm design for tight welding requirements or the need for floor space savings. This long reach (L) robot is perfectly suited for larger, distant or multiple welding zones.
