China IGBT Inverter ARC Plasma Cutter 220V/380V - Upgraded Fans & Auxiliary from Leading Suppliers & Factory
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. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.

Frequently Asked Questions
What materials can this plasma cutting machine cut?
The plasma cutting machine is highly effective at cutting all kinds of metals that are difficult to cut by oxygen cutting. It is particularly suitable for non-ferrous metals such as aluminum, copper, titanium, and nickel.
What are the main advantages of plasma cutting over traditional oxygen cutting?
When cutting metals with small thicknesses, the plasma cutting speed is exceptionally fast. For instance, when cutting ordinary carbon steel sheets, the speed can reach 5 to 6 times that of the oxygen cutting method. Additionally, it ensures a smooth cutting surface, minimal thermal deformation, and almost no heat-affected zone.
Which working gases are compatible with this machine?
Commonly used plasma arc working gases include argon, hydrogen, nitrogen, oxygen, air, water vapor, and certain mixed gases. The choice of gas directly affects the cutting characteristics, quality, and speed.
What are the installation power requirements for the LGK-80S and LGK-100S models?
Both models require an input voltage of AC 220V/380V (50/60Hz). The input cable must be ≥6.0mm² with a 63A power switch, and the output cable length should not exceed 25 meters.
What is the maximum cutting thickness for these models?
The LGK-80S has a maximum cutting thickness of 25mm, while the more powerful LGK-100S model can cut metals with a thickness of up to 35mm.
What environmental conditions are required for operating this machine?
The machine should be operated in ambient temperatures ranging from -10°C to +40°C. Ensure that the air inlet and outlet are not blocked, avoid direct sunlight exposure, and pay close attention to dust prevention to maintain stable operations.
