LGK-630HD Inverter air plasma cutting machine
Classification: High frequency plasma cutting machine
The LGK-630HD is a high-power air plasma cutter specifically designed for cutting thick metal plates, with a rated output current of >630A and a handheld cutting capacity of up to 170mm. Compared to high-power plasma cutters using power-frequency transformers, this power source is lighter, more compact, more efficient, and more energy-efficient. It also features robust control, monitoring, and protection functions, ensuring stable and reliable operation. Optional analog and RS485 digital communication interfaces are available for integration with automated cutting equipment, making it suitable for machine-based cutting applications.
