What is plasma cutting?

Plasma cutting is a process in which an electric arc ionizes the working gas (most often compressed air, nitrogen, argon, or gas mixtures), creating plasma at a very high temperature. A concentrated plasma stream melts and removes metal, leaving a clean cut edge. Thanks to this, plasma burning is an excellent solution for electrically conductive materials, such as steel, aluminum, or copper.

What are the key plasma cutting parameters?

To achieve the best cutting results, plasma cutting parameters, which have a direct impact on the quality and efficiency of the process, must be set precisely. The most important parameters include:

• Current intensity (A) - determines the power of the plasma arc and affects the ability to cut different material thicknesses. The higher the current, the greater the thickness of the cut sheet.
• Arc voltage (V) - affects arc stability and the quality of the cut edge.
• Cutting speed (mm/min) - too low a speed causes excessive melting of the edges, while too high a speed may lead to inaccurate cutting through.
• Type and pressure of the working gas - proper gas selection is crucial in the process of cutting different metals. For example, nitrogen and argon are used for plasma cutting of aluminum, and air and oxygen work well for processing carbon steel.
• Distance of the torch from the material - affects the shape and quality of the cut. Too great a distance causes energy losses, and too small a distance may lead to nozzle damage.

To achieve the best results, it is worth using high-quality equipment, such as plasma cutting machines available in the offer of the industrial machine manufacturer.

How to cut with plasma correctly?

Are you wondering how to cut with plasma correctly to achieve a satisfactory effect? For the plasma cutting process to run smoothly and ensure high edge quality, several key rules must be followed. How to cut with plasma?

1. Selecting the appropriate parameters - for each type of metal and thickness, optimal current, voltage, and cutting speed settings should be selected.
2. Using the appropriate working gas - depending on the type of material, we choose nitrogen, argon, oxygen, or air.
3. Maintaining a constant torch distance from the material - modern tables for plasma cutting machines make precise cutting guidance easier.
4. Regular machine maintenance - replacing worn parts, such as electrodes and nozzles, ensures process stability.

Cutting different materials with plasma

Plasma cutting technology, parameters, and other guidelines work well for different types of metals. It is worth paying attention to the specifics of processing individual materials:

• Plasma cutting of stainless steel - requires the use of inert gases, such as argon or nitrogen, which minimize oxidation.
• Plasma cutting of sheet metal - selecting the appropriate cutting speed and current intensity is crucial.
• Plasma cutting of aluminum - requires the use of special gases, such as nitrogen or water mixtures, to avoid discoloration.
• Plasma cutting of stainless steel - requires high precision, therefore it is worth using advanced plasma burning machines.
• Plasma cutting of metal - works well in various branches of industry, including automotive, construction, and shipyards.

Thanks to advanced technology available in CNC machines, it is possible to quickly and precisely make complex shapes.
