FAQ
Can the 600kg welding positioner be operated continuously at full load over extended periods?
+
-
Yes. The entire unit features an industrial-grade, heavy-duty design capable of supporting continuous 24-hour operation. It can stably handle its rated horizontal load of 600kg over the long term without any vibration or structural deformation.
How accurate is the equipment's rotational speed? Will the welding process suffer from inconsistent speeds-sometimes too fast, sometimes too slow?
+
-
The unit comes standard with an industrial Variable Frequency Drive (VFD) system, offering stepless speed regulation. This ensures linear and stable speed control, buffered starts and stops free of inertial drift, and uniform rotational velocity-fully meeting the requirements for precision circumferential welding processes.
How stable is the tilt angle positioning? Is there a risk of the workpiece slipping or shifting during operation?
+
-
It utilizes a mechanical self-locking structure based on a worm gear mechanism. This allows the unit to automatically lock in place at any desired tilt angle, ensuring that the load remains securely positioned without shifting or slipping. It offers high positioning accuracy and robust safety.
Can this unit be integrated and synchronized with an automatic welding machine?
+
-
Yes, it supports synchronized operation with all major types of welding equipment-including TIG, MIG/MAG, and Submerged Arc (SAW) welders. This enables synchronized start/stop functions and rotational movement, facilitating fully automated circumferential welding operations.
