Technical Superiority
Key Engineering Features
360° Precision Rotation
High-torque worm reduction gearboxes provide smooth turn-rates without back-lash, ensuring continuous seam quality during circular welding.
VFD Speed Control
Digital AC Variable Frequency Drives allow operators to fine-tune rotation speed precisely to match wire feed speed and process requirements.
Robust Grounding System
Heavy-duty brass current collectors under the faceplate protect rotation bearings and gearboxes from welding current arc damage.
Anti-Backlash Gear Train
Self-locking worm gear drives prevent table drift under eccentric or heavy offset loads, maximizing operator safety during manual or automated operation.
Machined T-Slot Faceplates
Heavy steel faceplates feature concentric alignment rings and radial T-slots to accept standard chucks, fixtures, or custom clamps.
Automation Ready Interface
Includes auxiliary contacts for arc start/stop synchronization with MIG, TIG, SAW power sources, and welding carriages.

Technical FAQ
Frequently Asked Questions
What is an automated welding positioner used for?
An automated welding positioner holds, rotates, and tilts workpieces (such as pipes, flanges, and pressure vessel heads) into an optimal downhand welding position. This increases weld deposition rates, improves bead appearance, minimizes operator fatigue, and reduces defect rates.
What load capacities are available in the APS ATT Series?
APS manufactures ATT Series positioners with load capacities ranging from 50 kg for light workshop components up to 10,000 kg (10 Tons) for heavy industrial fabrication.
How do I calculate the required positioner capacity for my workpiece?
You must evaluate total workpiece weight, center of gravity (CG) distance from the table surface, and eccentricity (offset from the rotation axis). Our engineering team can analyze your drawing to recommend the proper ATT model.
Can APS welding positioners be integrated with automated welding machines?
Yes. APS positioners feature built-in control terminals to interface with MIG/MAG, TIG, SAW power sources, welding column & boom systems, and robotic cells for synchronized arc start/stop and rotation speed triggering.
Are custom table sizes and rotation speeds available for overseas buyers?
Yes. Because we design and manufacture in-house, we can customize faceplate diameter, T-slot arrangements, center heights, rotation RPM ranges, and input supply voltages according to customer specifications.
What quality testing is performed before export delivery?
Every machine is tested for full load capacity, tilting torque limits, VFD speed regulation, emergency stop response, and grounding contact resistance prior to protective export packaging.
