IGBT Air Compressor with Enhanced Capacitor and Dual Fans - China Suppliers & Factory for Superior Performance
Detailed Information
- The advantages of the plasma cutting machine are that the plasma arc energy is more concentrated, the temperature is more localized, the cutting speed is faster, the deformation is smaller, and it can cut stainless steel, aluminum and other materials. Plasma cutting machine has the advantage of cutting thick plates, because the cutting speed is much higher than laser and flame.
- The plasma arc can cut various metals, such as stainless steel, heat-resistant steel, titanium, molybdenum, tungsten, cast iron, copper, aluminum and aluminum alloy, cutting stainless steel. Aluminum thickness up to 200mm or more.
- The plasma arc cutting speed is faster, and the production is relatively partial.
- When cutting the plasma arc, you can get a relatively narrow radian, clean, tidy, no sticky residue, close to vertical incision, small incision deformation and thermal influence, small change in hardness, and good cutting quality.

Frequently Asked Questions
What materials can be cut using this plasma cutting machine?
The plasma arc can cut a wide variety of metals, including stainless steel, heat-resistant steel, titanium, molybdenum, tungsten, cast iron, copper, aluminum, and aluminum alloys.
What is the maximum cutting thickness of these machines?
The maximum cutting thickness varies by model: LGK-70F cuts up to 20mm, LGK-100F up to 30mm, LGK-130F up to 35mm, and LGK-160F up to 40mm. Some specialized plasma configurations can cut aluminum and stainless steel thicknesses up to 200mm or more.
What input voltage and power settings are required for installation?
For the LGK-70F, it requires AC220V/380V. For LGK-100F, LGK-130F, and LGK-160F, a three-phase AC 380V 50Hz/60Hz supply is required. The installation requires an input cable of ≥6.0mm² and a 63A power switch.
What are the advantages of plasma cutting over laser and flame cutting?
Plasma cutting offers highly concentrated arc energy, faster cutting speeds (especially for thick plates), minimal thermal deformation, and clean, narrow cuts with close-to-vertical incisions and no sticky residue.
What is the benefit of non-contact high-frequency arc ignition?
Non-contact high-frequency (HF) arc ignition ensures a high success rate of starting the arc and minimizes electromagnetic interference with surrounding electronic equipment.
What environmental conditions are necessary for safe operation?
The machine should be operated in ambient temperatures between -10℃ and +40℃. Ensure the air inlets and outlets are unblocked, avoid direct sunlight exposure, and protect the system from excessive dust.
