IGBT Inverter ARC Plasma Cutter 220V/380V - High-Performance Factory Suppliers in China with Enhanced Features
Detailed Information
Plasma cutting machine can cut all kinds of metals that are difficult to cut by oxygen cutting with different working gases, especially for non-ferrous metals (aluminum, copper, titanium, nickel) cutting effect is better; its main advantage is that when cutting metals with small thickness, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat-affected zone.
Plasma cutting machine, the working gas that can be used (the working gas is the conductive medium of the plasma arc and the heat carrier, and the molten metal in the incision should be excluded at the same time) has obvious effects on the cutting characteristics, cutting quality and speed of the plasma arc influences. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.

Frequently Asked Questions
What metals can this plasma cutting machine cut?
The plasma cutting machine can cut all kinds of metals that are difficult to cut by oxygen cutting, especially non-ferrous metals such as aluminum, copper, titanium, and nickel.
What are the main advantages of plasma cutting over oxygen cutting?
For thin metal sheets, plasma cutting is significantly faster—reaching up to 5-6 times the speed of oxygen cutting. It also yields a smooth cutting surface, minimizes thermal deformation, and creates almost no heat-affected zone.
Which working gases are recommended for this machine?
Commonly used gases include argon, hydrogen, nitrogen, oxygen, compressed air, water vapor, and specific mixed gases. The choice of gas directly affects the cutting quality, speed, and overall characteristics of the arc.
What cutting thickness can the LGK-80S and LGK-100S handle?
The LGK-80S model supports a cutting thickness of up to 25mm, whereas the LGK-100S model supports a cutting thickness of up to 35mm.
What are the requirements for installation and power connection?
The machine requires an input voltage of AC 220V/380V (50/60Hz), an input cable size of ≥6.0mm², and a 63A power switch. Ensure the output cable does not exceed 25 meters and that there is no blockage on the air inlets and outlets.
What is the benefit of the IGBT inverter technology used in these machines?
IGBT inverter technology provides high load endurance, making the machine suitable for long-time cutting operations. It ensures a stable cutting current, a consistent plasma arc, and high-frequency non-contact arc ignition with minimal interference.
