LGK-105: Entry CNC plasma model, stable performance, suitable for conventional medium and thick plate cutting, daily industrial processing and maintenance work.
LGK-125: Mid-range upgraded model, stronger cutting power, ideal for batch cutting of steel structures and medium-heavy industrial plates.
LGK-165: High-power heavy-duty model, maximum cutting capacity, specially designed for 50mm ultra-thick plate cutting and long-term CNC automatic production.
Q1: Is this machine compatible with CNC cutting machines?
Yes. The machine features a dedicated external CNC interface, fully compatible with all imported and domestic CNC cutting power supplies on the market, enabling fully automatic cutting production when connected to CNC equipment.
Q2: What is the purpose of the 2T/4T modes?
2T mode is suitable for short-distance, intermittent manual cutting; 4T mode supports long-duration continuous cutting and is compatible with CNC automated operations, significantly reducing labor intensity.
Q3: What are the advantages of the delayed gas shut-off function?
Delayed gas shut-off after cutting provides continuous cooling to the torch, effectively protecting vulnerable parts such as nozzles and electrodes, reducing consumable waste, and extending service life.
Q4: What are the benefits of the external air pump design?
The external air pump structure makes the machine lighter and more flexible, facilitating on-site handling and mobile operation. It is suitable for both fixed workshop production and outdoor construction projects.
