What are the Functional Properties of Plasma Cutters and Its Advantages?

Metal cutting can be classified into two – mechanical and thermal cutting. Plasma cutting is a thermal cutting process where ionized gas is applied for casting the metal.
It is one of the most popularly used methods to cut thick metal plates but is also available for sheet metal. Before leaping into the benefits and skills of plasma cutting, we should take another issue.

What Is Plasma?

You have heard of the 3 central states of things – solid, fluid, and gas. But there is one additional state as well. Yes, it is plasma.
It is likely to see plasma in nature but chiefly in the upper sections of Earth’s atmosphere. The famed polar lights are an effect of solar winds made of plasma. Lighting and high-temperature fire also hold plasma. And so does our structure.
Altogether, it forms up about 99% of the visible world.
In our daily world, we can see plasma in TVs, fluorescent lamps, neon signs, and, of course, plasma cutters.

How Does a Plasma Cutter Work?

The plasma cutting method is thermal. This intends that it applies heat to melt the metal instead of automatically cutting it.
The overall mechanics of the system is ever the same. Plasma cutters use condensed air or other gases, such as nitrogen. The ionization of these gases takes place to form plasma.

Generally, the compressed gases come into contact with the electrode and then ionize to form more pressure. When the pressure makes up, a stream of plasma is driven towards the cutting head.
The cutting tip tightens the flow to form a stream of plasma. This is then reduced to the workpiece. As plasma is electrically conductive, the working is combined to the ground by the cutting table.
As the plasma arc touches the metal, its extreme temperature melted it. At the very time, the high-speed gases air away from the melted metal.

Benefits of Plasma Cutting


  • Able to cut all conductive materials. Flame cutting, though also fit for cutting thick metals, is defined as ferrous metals only.
  • Best quality for thickness up to 50 mm.
  • Highest thickness up to 150 mm.
  • Almost affordable for medium thickness cuts.
  • Best way to cut average thickness stainless steel and aluminum.
  • Proteus machines are available to give high accuracy and repeatability.
  • Can cut in water, ending in smaller HAZ. It also decreases noise levels.
  • Smaller cutting kerf related to flame cutting.
  • Faster cutting rate than oxy-fuel.

Picking a Cutting Method

Making your selection between distinct cutting systems comes down to the material, density, and use of the parts.
Also, plasma cutting is faster and more affordable, with plates rising from around 15 mm. Then again, the problem comes down to the essential quality. It is, though, always likely to get a fine and even effect with the post method.


These are the advantages of the plasma cutter and a brief description of its working. Here you will get the best plasma cutters that will make your working easier and precise—the best product to ionize by casting the metal.
