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.

Arc-Welding Robot Manipulator

• 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
