Servo Rotary Positioning ARC Welding Robot System 720B

The OTC SERVO-ARC 720B servo-controlled turntable positioning cell is designed for medium and large size parts with minimal operator movement required. The operator can prepare the work on side A while the robot is welding on side B.

This basic cell provides cost savings with a smaller base and floor mounted safety fencing.

The SERVO-ARC 720 series can be supplied with either a standard or long arm robot manipulator to accommodate customer part needs.
