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.

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
