Long arm with a maximum payload of 8kg The range of welding applications has been expanded. Due to the industry’s fastest speeds, cycle times are reduced. Slimmed lower arm and reduced rotating radius. Avoiding the interference with jigs or workpiece. All cables required for Synchro-feed welding are also built in the lower arm. Avoiding the interference behind the arm. The maximum payload has been increased by 30%, up to 8kg. Enabling the use of a variety of torches and sensors. It is also good for handling application.
