Plasma Cutting (řezání plazmou): A Modern and Efficient Method for Metal Cutting

High-quality metal cutting is the foundation of many jobs – from repairs of agricultural machinery to steel structures and custom metal fabrication. Today, we'll look at plasma cutting, what it exactly is, how it works, its advantages and disadvantages, and why it could be a great addition to your services.

How does plasma cutting work? The plasma beam is created by ionizing gas (most often compressed air or nitrogen) with an electric arc. The temperature reaches up to 20–30 thousand °C, melting the metal and blowing it away from the cut at high speed. The result? A clean and fast cut with minimal heat impact on the surrounding area.

Advantages of plasma cutting:

• Speed – Several times faster than traditional flame cutting or grinding.
• Versatility – Cuts conductive metals: steel, stainless steel, aluminum, copper, brass... Ideal for sheets up to 30–50 mm thick.
• Precision – With CNC machines, you can achieve complex shapes with minimal waste.
• Mobility – Hand-held plasma cutters are lightweight and portable – perfect for mobile services in the field (e.g., repairs of excavators or trailers).
• Low costs – Only needs electricity and compressed air, no expensive gases.

Disadvantages:

• Wider kerf (2–5 mm) than laser → less precise on very thin materials.
• Higher noise and smoke → requires good ventilation and protection.
• Does not cut non-conductive materials (wood, plastic).

In Třebíč and the Vysočina region, there are plenty of farmers, construction companies, and transport firms that need quick cutting of sheets for repairs of excavator buckets, trailers, gates, or steel structures.  Svářeč Třebíč offer a complete package: cutting + welding + repair right on site.
