OTC FD-B4S Welding robot
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
FD11 ROBOT CONTROLLER
• Windows XP based open architecture
• Large memory capacity and 40 Input / 40 Output control signals
• Advanced PLC functions allow for ladder diagram editing directly through the teach pendant
• Network capabilities – connects to Ethernet, DeviceNet, and PROFIBUS connections (may require additional hardware)
TEACH PENDANT
• Icon displays assist in quick & easy teaching
• 640×480 VGA color screen with LED backlight 65536 color display
• 3 position enable switch provides increased safety
• Multi-screen function allows user to view up to 4 screens simultaneously
