The first and most obvious advantage is that plasma cutting can be done on practically all types of metals. Using oxygen to burn the metal is possible only if the metal supports burning. If the metal is burn resistant, that is to say it does not support easy oxidization, using oxyfuel will be counter productive. This is true in case of stainless steel etc. If you use oxyfuel to burn and cut the metal, you will have to spend a lot of time on the job and it will be the most inefficient way to cut the metal.
On the other hand, plasma cutting machine is not dependent on the affinity of the metal to oxygen. It will work irrespective of whether the metal supports oxidization or not. This is because the cutting is not done by a flame. Rather, it is done super heated air which has turned into plasma. Since plasma will cut all metals irrespective of their characteristics, this method is perfect for cutting all types of metals.
The second advantage that plasma cutting machine help you get your job done a lot faster than any other method. This method can help you cut a lot faster than oxyfuel or even laser cutting methods. You will enjoy a big advantage if you opt for a plasma cutting machine to cut metals up to 2 inches thick. As thickness increases, the benefits of opting for a plasma cutting machine increases. If the thickness is above 1/8th an inch, then this system is better than even laser cutting. If you use the right technique, you can go up to 500 inches per minute on a metal that is one gauge thick. Good speed means you can get more done in less and can earn more profits from your projects.
A Plasma cutting machine requires very little training. Provide the basic minimum training to your employee and he or she is ready to operate the machine. Unlike other methods, it is not very difficult to complete the cut as required for the project. The working environment too does not need any major overhaul. On the other hand, installation of a laser cutting system will require investment in setting up the necessary infrastructure as well.
A Plasma cutting machine works a lot cheaper than any other cutting method. In some cases, the cost of cutting is less than even half of the cost of using oxyfuel.
