Our air compressor built in plasma cutting machine is designed with advanced inverter technology and is suitable for plasma cutting systems that use compressed air to cut. The emergence of variable welding and cutting equipment benefits from the appearance of inverter power supply theory and devices:
1) CUT-40/60/80/100/160 inverter cutting power supply uses high-power device IGBT to convert 50/60Hz power frequency to medium frequency. Subsequently, the voltage is reduced and the current is adjusted. At the same time, pulse bandwidth modulation technology (PWM) is used. Can produce a powerful large power supply that can be used for cutting.
Compared with traditional rectification and conversion technology, the advantages of inverter technology are mainly in the obvious low energy consumption, lighter weight, and the structure is smaller and more compact, and the performance is better. Built-in air compressor plasma cutting machine, you can work anytime and anywhere.
Our series of plasma cutting power supplies can provide a stronger, more concentrated and more stable arc. The air in the arc is almost all electric the arc temperature can reach 10000-16000°C, reaching a high degree of ionization, forming a powerful plasma arc. This means the plasma arc can be used to cut metal quickly, and the heat affected zone can be reduced as much as possible, and the energy can be effectively used.
It can be used and can obtain an extremely smooth cutting surface, which brings convenience for subsequent processing.
Compared with other cutting power supplies, our series of inverter plasma cutting power supplies can provide fast electricity through advanced electronic circuits.
Source adjustment and control, with first-class cutting operation characteristics and extremely high conversion efficiency.
Our series of plasma cutting power supplies have many uses.
It can be used when the equipment cannot be cut, and can be used for various metal materials with different properties, including stainless steel, alloy steel, carbon steel, copper and other non-ferrous metal materials. This machine can cut the plate into complex shapes as required.

Internal components
Possible problems and analysis when cutting The phenomena listed here may be related to the accessories, gas supply, environmental factors, and power supply conditions you use. Please try to improve the conditions of use to avoid such situations.
1. The cutting surface is rough and uneven, and the cutting effect is not ideal.
Such conditions indicate that the performance of the cutting machine has not been effectively used. You can check the following:
A. Confirm that the compressed air source is stable and has sufficient pressure, and usually enters the cutting machine The gas pressure should not be lower than 0.3 MPa (approximately 3 Kg/cm 2 ), the variation range should be within ±0.05 Mpa.
B. The diameter of the electrode and nozzle does not match the cutting current. The matching relationship between cutting current and nozzle is as follows:
| Current range |
10-30A |
30-40A |
60-100A |
| Nozzle diameter |
1.0mm |
1.2mm |
1.3mm |
2, it is difficult to start the arc, and the arc is easy to break:
A. Confirm that the electrode you are using is of good quality. The discharge capacity of poor quality electrodes may not meet the requirements.
B. When the cutting current is too small and the air flow is too large, the arc will break due to excessive cooling.
C. The voltage of the power grid is too low or the primary input line is too long, resulting in excessive voltage drop on the line.
3. The output current cannot reach the rated value
The deviation of the power supply voltage from the rated value will cause the output current value to be inconsistent with the set value. When the power supply voltage is lower than the rated value, the maximum output current of the unit may also be lower than the rated value.
4, the current cannot remain stable during the use of the cutting machine. This situation may be related to the following factors:
A. The voltage of the power grid changes;
B. Serious interference from the power grid or other electrical equipment.
5. The electrode or nozzle burns out too quickly
A. The current may be adjusted too much and the nozzle diameter used is too small.
B. The air pressure is too low to reach the required flow rate, the cooling effect is weakened, and the nozzle electrode is overheated.
6, the arc cannot penetrate the steel plate completely, or the incision sticks severely and cannot cut smoothly
A. It is possible that the current of this machine cannot reach the required cutting thickness, please use a cutting power supply with a larger current.
B. The electrode or nozzle has burnt out and needs to be replaced.
