Product Description
LGK-300/400/500 Air Plasma Cutting Machine (CNC Type)
The LGK-300/400/500 series is a professional-grade air plasma cutting machine engineered for integration with portable CNC, gantry CNC, and robotic cutting systems. Built on IGBT module soft-switching technology, it delivers stable, reliable performance across demanding industrial cutting environments.
Models covered: LGK-300 | LGK-400 | LGK-500
Key Features
- IGBT module soft-switching technology for stable and reliable operation
- Designed for portable CNC, gantry CNC, and robotic cutting systems
- High duty cycle, suitable for long continuous cutting
- Non-contact high-frequency pilot arc ignition: high success rate with low interference
- Automatic under-voltage, water-shortage, and over-heating protection to prevent torch damage
- Precise, stepless adjustable cutting current for workpieces of different thicknesses
- Wide mains voltage tolerance: cutting current and plasma arc remain very stable
- Excellent arc stiffness, clean cut edge, and outstanding cutting performance
