Air plasma cutting, MMA manual arc welding, support built-in & external air source, 2T/4T trigger mode
Low-carbon steel, stainless steel, aluminum, cast iron and other non-ferrous & alloy metals. Widely used in shipbuilding, steel structure fabrication, metal processing and heavy-duty workshop operation.
The arc energy is concentrated and stable with powerful cutting capacity, delivering smooth and neat cutting surfaces.
Fast cutting speed, 3‑5 times faster than traditional flame cutting, with low operating cost.
High‑frequency non‑contact arc ignition, high arc‑striking success rate and no high‑frequency interference.
Accurate display of cutting current; pre‑gas and post‑gas delay time can be precisely adjusted.
Built‑in air compressor with self‑cooling function, independent operation without external air source.
Maximum cutting thickness up to 30 mm with uniform cutting surface.
External air source is optional to flexibly meet various working requirements.
Equipped with 2T/4T trigger modes for long‑time cutting operation, effectively reducing operator fatigue.
Easy installation and operation, ready for use once powered on to improve working efficiency.
Widely used in multiple industries, especially suitable for processing large structural components such as ship‑building parts.

LGK-80NK: Heavy-duty entry-level unit. Suitable for small-medium workshops, site maintenance and intermittent heavy-duty work, max cutting thickness 30mm. Not recommended for non-stop 24-hour full-load production.
LGK-100N: Mid-power heavy-duty model. Perfect for standard heavy-industry workshops, medium-heavy steel-structure batch processing with long-time continuous operation.
LGK-130Y: Top-tier heavy-duty model for large heavy-industry workshops. Ideal for shipbuilding and large structural components, supports high-frequency full-load long-time cutting tasks.
Q1: What working modes does the machine support?
A1: It supports two working modes: air plasma cutting and MMA manual arc welding. One-key switching realizes dual functions with one machine.
Q2: Does it support external air source? How to solve the air supply?
A2: The machine is equipped with a built-in air compressor with self-cooling function, which can work independently without external air source. It also reserves an external air interface for flexible switching according to site conditions.
Q3: What is the maximum cutting thickness?
A3: LGK-80NK max cutting thickness is 30mm carbon steel with smooth and uniform cutting surface. LGK-100N and LGK-130Y support thicker plates to meet heavy-duty industrial cutting requirements.
Q4: What are the 2T/4T functions for?
A4: 2T mode is suitable for short and intermittent cutting. 4T mode is designed for long-time continuous cutting without holding the trigger, greatly reducing operator fatigue.
Q5: Is plasma cutting faster than flame cutting?
A5: Yes. Its cutting speed is 3 to 5 times faster than traditional flame cutting, with smaller heat-affected zone, less workpiece deformation and lower operating cost.
