• Air-cooled welding torch is fixed while workpiece rotates; welding position is horizontal.
• Welded machine body with longitudinally adjustable pneumatic tail-stock and torch.
• Workpiece positioned by special fixture and pressed by pneumatic thimble for synchronous rotation.
• Japan OMRON PLC control with inverter-based stepless speed adjustment.
• High-performance Japan OTC welding power source for stable arc and uniform seams.
• Touch man-machine interface for presetting parameters: welding length, current, voltage, speed, and oscillating frequency.
• Digital Analog (D/A) control for multi-layer continuous welding without arc stopping.
• Welding oscillating mechanism specifically designed for wide and multi-layer seams in hydraulic cylinders.

Normally we use fumigation plywood cases for packaging. Large machines may use steel pallets with plastic film covers. All machines are treated with anti-rust paint or oil before leaving the factory.
