Plasma cutting of metal is a modern method of processing rolled metal and finished products, allowing in a short period of time to produce a high-quality cut with smooth edges, without deformation and with minimal waste. That is why this technology is widely in demand in many fields of activity: shipbuilding, utilities, mechanical engineering, enterprises producing steel structures and metal products, etc.
Plasma cutting technology is based on the interaction of electricity and working gas, when a stream of compressed air passing through an electric arc reaches a temperature of +30000°C and is ionized. Ionized gas is called plasma. A directed plasma jet is used to cut metal, alloy steel, and various alloys.
The components of plasma cutting are:
- Plasma unit (plasma torch)
- Compressor
- Power supply
- Ground clamps
- Hoses.

How to choose a plasma cutter
Before purchasing this device, evaluate the following characteristics:
- Versatility. Some devices are suitable for both metal cutting and stick electrode welding, argon arc welding. However, you need to understand that multifunctionality often has a negative impact on the quality of operations and productivity levels. Universal plasma cutting devices rarely cope with material whose thickness exceeds 11 mm.
- Current strength. With a higher current, the arc heats up more, which means cutting takes less time.
In addition, you can cut parts of greater thickness. Therefore, before purchasing, it is important to understand what you are going to do with this device, what parts to work with. For processing steel no thicker than 20 mm, a device with a current of 20 A is suitable. For thicker sheets, more power is needed - in the range of 40–60 A. For devices used in industry, this parameter is 200 A and higher. - Electrical network type. Household devices even operate on a 220 V network, but you need to be prepared for the fact that the current in them rarely exceeds 40 A. Industrial devices require a 380 V network.
- Duration of switching on (DS). This indicator is set as a percentage and records the time during which the plasma cutter can operate. A working cycle of 10 minutes is taken as a basis. That is, if the PV is 70%, it means that after 7 minutes of operation the device should cool down for 3 minutes. At 40%, the device can work for up to 4 minutes, and then it will need a 6-minute break. You can also find devices with a duty cycle of 100%; they are able to work without stopping, since they use water cooling.
- Compressor. This element of the system can be built-in or separately connected. For home use, devices with a built-in compressor are more convenient. However, they have a drawback - low power. For professional work you will have to purchase a separate compressor. Its task is to provide the plasmatron with constant pressure of dry air. Pulsations are not allowed, and the pressure level must be adjusted to the requirements of the device.
- Convenience. The sufficient length of the cable and hose package is responsible for this property. If the device will be used only at home, it is better to choose a small model to simplify the work.

Types and benefits
Based on their functions, there are two types of compressors for plasma cutting:
- Piston;
- Screw.
Models with a piston are more common due to their low cost and practicality, they are reliable, do not require special maintenance and high-cost repairs in case of unexpected breakdowns. But for industrial production, where metal cutting is a continuous process, it is worth choosing screw compressors, which are characterized by high efficiency and low power consumption.
For household use of a plasma cutter, it is enough to purchase an inexpensive oil-free compressor. Such a compressor will provide the minimum need for compressed air, which is necessary for low-intensity operation of the plasma cutter. Another advantage of oil-free compressors is the low noise level, which is an important factor when you are close to the compressor. Specialists will need a professional compressor for plasma cutting when working in production.
