VFD Stepless Speed Regulation
Frequency conversion drive, smooth rotation, adjustable speed to match different welding processes.


Self-locking Tilting Mechanism
Worm gear self-locking design, the table can be locked at any angle from 0° to 90°, safe and reliable.
Dual Control System
Equipped with control panel and foot pedal, easy operation, save labor and improve working efficiency.

Quality Control
Raw Material Inspection
All steel materials and core accessories are strictly screened and inspected to ensure qualified basic quality.
Precision Machining
Key parts are processed by CNC equipment to ensure precise assembly and overall structural stability.
Full Load Testing
Each machine undergoes 300kg full-load test and long-time aging test to ensure stable operation.
Electrical System Debugging
Calibrate frequency conversion and circuit system with anti-interference design for stable welding operation.
Angle & Locking Test
Detect 0-90° tilting and self-locking performance to ensure accurate positioning and safe use.
Finished Product Inspection
Comprehensive check on appearance and performance, only qualified products are delivered.
Working Principle
Driven by variable frequency motor and worm gear transmission, the 300kg welding positioner realizes stable 360° uniform rotation. The 0-90° tilting function adjusts workpieces to the optimal welding angle, converting difficult overhead welding into flat welding, which simplifies operation and ensures neat weld beads.
