A plasma cutter is one of the most precise cutting machines on the market today. It uses inert gas forced out of a nozzle at very high speeds and through an electrical arc to create plasma. The plasma can be directed to a very specific line through the use of a system that allows a computer to control the movement of the plasma cutter.
This type of computerized plasma cutter is used in all types of manufacturing industries, in fabrication, in the cutting of parts for the machinery, automotive and aerospace industries. It is also commonly found in custom steel services and even in smaller shops around the country that complete any type of custom work for steel or other types of materials where complex cutting is required.
Table or Hand Held Design
There is the option for smaller plasma cutters, typically for home or light-duty use to be a highly portable, hand-held type of cutting tool. However, for industrial and commercial use or where very specific types of cuts are required, the computerized plasma cutter is the best option.
These may also be called CNC plasma table, and they can be designed to handle different sizes of metal plate as well as provide different cutting speed options. The type of application as well the specific demand for the plasma cutter will be critical factors to consider when making a choice.
Duty Cycle
The duty cycle of any type of plasma cutter, including a computerized plasma cutter, is very important, particularly if it is going to be in continual or frequent use. The duty cycle is directly related to the amperage output, which means a higher amerage output is more desirable for continual use.
Generally, increasing in size is the best recommendation, particularly if the shop or manufacturing area has a variety of needs for the plasma cutter. Going too low will simply not provide the cutting ability required.
Cutting Speed
The best plasma cutters that are computer controlled have rated top cutting speed to achieve a precise, quality cut. There are different ratings for cutting based on the type of quality and the cut speed on specific thicknesses of metals.
It is also important to consider the ease of use of the machine. Some of the CNC plasma cutters are complicated to use while others are intuitive and require little in the way of training.
