OTC DAIHEN A2PF Series 2-Axis Servo Welding Positioner System
The OTC DAIHEN A2PF Series (A2PF300, A2PF500, A2PF1000) represents the pinnacle of dynamic motion coordination in robotic welding automation. These high-precision 2-axis (tilt and rotation) servo positioners are controlled directly by the OTC robot controller as synchronized external axes. By continuously manipulating complex workpieces in real time during the arc welding cycle, the A2PF positioner ensures that complex multi-angled joints are always welded in the flat gravity or horizontal ‘boat’ position. This eliminates out-of-position welding defects, boosts deposition rates, and produces visually stacked weld beads on construction machinery, automotive sub-frames, and heavy agricultural equipment.

🔧 Engineering & Operational Guide
- Dynamic Coordinated Motion: When programming synchronized welding paths, utilize the OTC teach pendant’s coordinated motion mode. Ensure the Tool Center Point (TCP) velocity relative to the workpiece remains constant even as the positioner tilts and rotates simultaneously.
- Grounding & Electrical Isolation: Attach the welding ground clamp directly to the positioner’s dedicated rotary grounding terminal. Never allow high-amperage welding current to pass through the precision servo motor bearings or harmonic reduction gears.
- Payload & Center of Gravity: When designing workpiece holding fixtures, ensure the combined weight and center of gravity of the fixture and workpiece stay within the rated allowable torque and tilt moment limits of the specific A2PF model.
