How Does Plasma Cut Metal

Plasma cutters are the industrial-leading machine that works dedicatedly for metal fabrication and its cutting. However, this is not as simple as you would slice off the bread. Since it’s a proper machine with lots of technical aspects, chances are you don’t know who does plasma cut metals.

Since we are living in this age where the work of metal and its fabrication is not a new thing anymore, the innovation in the process is always welcoming. Plasma cutters are making worthwhile performances in building cranes, robots, sky-highly building cars, suspension bridges, and whatnot.

But if you are an aspiring metal worker, things can be somewhat strange to get a fuller understanding. But the best of it is you have landed here; on this page. Today we shall take a look at how plasma cutters cut metal and what process they follow to let out such precise, accurate, and smooth final results.

How Does Plasma Cut Metal?

Plasma cutters cut through the metal using the hottest and fast jet of plasma through the conductive metals. Plasma cutters only work for conductive metals. It works to make the plasma using the electrically charged arc that is passed through a gas (gas can be nitrogen or oxygen).

It shoots the electric arc using compressed air and then ionizes it with the power increased flow of electrons. It then generates a flame that is highly powerful to cut through the heavy-duty industrial metals. The flam initiated by the arc is capable enough to melt the workpiece material hence the final cutting result becomes pretty smoother for its edges with the sleek polished contour.

When the plasma state is achieved it is then introduced through a smaller opening in the nozzle and then it’s ready to cut through the conductive metal. The torch of the plasma cutters is made with copper as a rule of thumb. It constricts the gas stream with the arc that flows through it.

To understand its working a bit deeper, the heat melts down the metal and the gas flow readily excludes it from the cut. We know plasma uses gasses that have hydrogen, nitrogen, or argon however you can also replace it with air. With the compressed air usage, the plasma cutters are highly competitive with the oxy-fuel process when it comes to cutting carbon-manganese and stainless steels up to 20mm thick.

The plasma cutting process works with ever so smoothness and the highlighted part is pretty safe and sounds too unlike the saw cutting.

The Plasma Cutting Process Is Ideal For

Plasma cutters work well for all kinds of electrically charged conductive metals. However, the metal thickness should be from 1 to 2 mm up to 1-2 inches. Mainly it cuts mild steel, stainless steel, carbon steel, copper, brass, aluminum, and expanded steel.


Plasma cutters work pretty smoothly and efficiently for cutting heavy-duty industrial metals. Mainly it works with such efficiency due to the gasses and other things that aid the arc. However, depending on the type of work
