Plasma Cutters

You must know that the plasma is the fourth state of the matter the other three being the solid, liquid and gas. The optimized use of the compressed gas channelized to generate an electric arc and it cuts through the metal sheet.

Industrialization and the allied processes have traversed the good and bad time in equal strides. The demand of the cutting edge technology has really increased in recent times. And one such cutting edge technology is the plasma - arc process. The plasma- arc process is not a new one. The history of the plasma arc goes beyond the time which is as old as the time when we were witnessing the zenith of the Second World War.

It is really well said that the requirements lead to invention and at that time there was a real requirement of the new technology in welding so that the process can be used I joining of the aircraft material. This effort leads to the invention of the method of the welding which used a proactive shield of inert gas. This shield functioned around the electric arc developed and protected the weld from oxidation or the reaction of the oxygen in the atmosphere on the weld.

The technology related to the plasma cutter was taken to the next level in the next two decade. It was soon found that if we restrict the opening through which the gas used to pass then the heat being generated is increased and this was really desirable for the process. It was also found out that the resultant which passed through the opening and in fact the reduction in the size of opening made the compressed gas to move even faster.

The plasma cutter really found the great application in no time. However the process was really very expensive. I do feel that whenever this has happened some new invention has taken place. For example you can take the example of the aluminum and you cannot forget the effort of Clark and it was only because of his effort that the price of the aluminum went on reducing. I do feel that the same thing happens with the plasma cutter technology. The manufacturer found it really very advantageous to burn the ferrous and non- ferrous metals. The plasma cutters which are available today are really very light and I must say that you easily transport them from one place to the other.

The cost of the process has also been reduced to almost nothing. Now this process is quiet affordable and the cost has really been reduced to the normal. These plasma cutters can be mounted on the trucks and we can take it to any site where we like.
