SRA series robots and their FD controllers are ideally suited to spot welding applications. The SRA robots are highly rigid and weight less, providing faster motion and less vibration. Advanced motion control from the FD controller provides top acceleration thereby shortening cycle-times. The FD also has 4th generation servo gun control software enabling higher motor speeds while maintaining gentle electrode contact to parts, optimizing spot welding performance. Finally, Nachi together with our welding partners, Obara and Art Hikari, are pushing the envelope in resistance welding with lightweight modular guns and spot welding solutions for aluminum parts.
