If you are not into construction industry, maybe plasma cutter would be a new thing for you.  But how does the best plasma cutter works? Let’s find out!

Plasma Cutter

A plasma cutter works by sending an electric arc through a gas that is passing through a constricted opening.  Gas can be of many forms such as nitrogen, argon, oxygen, etc. the electric arc elevates the temperature of the gas to the point that it enters 4th state of a matter.  For your benefit, the first three states are liquid, solid, and gas.  The fourth one may not be very familiar but scientist call this Plasma.  When cutting a metal, the metal becomes part of the circuit.  The electrical conductivity then of the plasma causes the arc to transfer the work. 

The restricted opening where the gas passes through causes it to squeeze by at a high speed.  This high speed gas cuts through the molten metal.  The gas then is also directed around the perimeter of the cutting area that shields the cut. If you want to know more about plasma cutter reviews, you can find its details on welderportal.com.

With the best plasma cutters today, a pilot arc between the electrode and nozzle is used to ionize the gas and initially generate the plasma prior to the arc transfer.

Now, in choosing the best plasma cutter, it is not enough that you have known the process of plasma cutting.  There are things to consider such as the type of plasma cutting that you usually do in your shop, cut quality which you may find out in some plasma cutter reviews, and of course its reliability. 

If you plan to move around your shop, or even do some tasks away from your shop, you need also to consider the size and weight in making decision.  Actually, some best plasma cutters are designed as lightweight without compromising power and performance.
