Core Advantages
- Worm gear self-locking tilting structure supports 0°-90° full-angle positioning, firmly fixing flanges, elbows and tank heads without repeated clamping
- 0.1-12rpm VFD stepless rotation with digital display outputs stable torque, smooth low-speed operation for consistent welding seams
- Thick cast iron turntable and stress-relief reinforced steel base eliminate vibration, stable long-term running under full 30kg load
- Dual control system: independent control cabinet + handheld remote, foot switch available as optional accessory
- Complete safety configuration: overload, overcurrent & emergency stop protection, IP54 dust & splash-proof electrical cabinet adapted to harsh welding workshops
- Multiple custom upgrades supported: three-jaw chuck, welding torch stand, wireless remote, electric tilting function
- All machines undergo 12-hour full-load aging test before delivery to guarantee stable quality
Application Scope
- Circular girth welding for standard pipe flanges, thick elbows and mini pressure vessel heads
- Circular seam machining for medium valve bodies, hydraulic connectors and mechanical hardware parts
- Polishing, grinding and surfacing overlay welding for disc-shaped metal workpieces
- Processing small hydraulic cylinder barrels and automobile exhaust pipe fittings

Production & Quality Inspection Standard
Cast iron turntable and base undergo annealing to eliminate deformation risk. Top brand electric parts ensure 24-hour stable running. Every unit gets full function inspection and mandatory aging test to meet international CE safety norms.
