During World War II, in an effort to improve the joining of aircraft materials, a method of welding was developed that used a barrier of inert gas around an electric arc to protect the weld from oxidation. This new welding method became known as plasma-arc.

Over the next few decades, this new technology underwent refinements, including the restriction of the opening through which the inert gas passed so as to greatly increase the heat produced. It was discovered that the smaller opening dramatically sped up the flow of gas and blew out a channel in the material affected, which resulted in a safer and simpler process for cutting iron and other metals.

Limited commercial use of the expensive plasma-arc cutting technology in the early 1960s eventually gave way to popularity as the units became more compact and affordable even for small businesses. Today, many manufacturers sell portable plasma cutters with built-in air compressors that can be carried easily on a truck to the job site.

Plasma cutters function by sending an electric arc through a gas as it passes through a constricted opening. The gas can be compressed air, nitrogen, argon, oxygen, etc. The arc elevates the temperature of the gas to the point where it enters the fourth state of matter called plasma. It is the electrical conductivity of the plasma that causes the arc to transfer to the work, while the high current causes the metal to melt. The nozzle’s restricted opening causes the gas to squeeze by at a high rate of speed and cut through molten metal. The gas is also directed around the perimeter of the cutting area to shield the cut.

Mistakes are very common in everything but the way to over come those mistakes can be learn with experience or through the experience of others. Now here is a way by which you can easy avoid one common mistake beginners do while using a plasma cutter. Discover how to learn by other’s trial and errors to avoid unnecessary metal cutting troubles using a plasma cutter.

The first best thing that you must do is to understand the nature of your plasma cutter by reading the manual clearly as each and every plasma cutter will have different specialties and performance range. Then you can always carry out a sample cut on same type of a material that you will be working to make sure that the settings and travel speed that you have chosen are just right. As beginners you would not like to see a good material going waste, so better go in for a trial cut to keep things cool.

The next easy thing that you have to do is to carry out and perform the movement that you will be doing over the material before you actually pull the trigger. This will enable you to know that your movement will be smooth without any trouble and your cut will come out just perfect.
