Frequently Asked Questions
Q: Can this machine cut stainless steel and aluminum?
A: Yes. Using compressed air, quality cut range is 3–14 mm for stainless steel and 3–10 mm for aluminum.
Q: Is the packaging suitable for sea freight?
A: Yes. Fumigation-free wooden crate. Stacking and vibration tested before shipment.
Q: Does high altitude or high ambient temperature affect the duty cycle?
A: The duty cycle is rated at 40°C / below 1000m altitude. Above these conditions, a 15-minute natural cooling period every 2 hours is recommended.
Q: Do you offer OEM or customization?
A: Yes. Panel labeling, packaging, and signal interfaces can be customized. Minimum order quantity discussed upon request.
Q: Is the LGK-65A Inverter Air Plasma Cutting Machine suitable for both handheld and CNC use?
A: Yes. The same unit supports handheld cutting now and can integrate with a CNC gantry system later when you scale up.
