Miller Plasma Cutters As Precision Tools

The working of a plasma cutter involves the application of plasma torch to cut metals such as steel of varying thickness. Traditional metal cutting devices such as saws and shears had serious disadvantages associated with them. The rate of work was slow and the cost of replacements brought down the overall efficiency drastically.

Another type of metal cutter that was in use was oxy fuel cutters. They delivered high performance compared to saws and cutting shears, but the work was never clean. Special labor had to be employed to clean up the metal cutting leftovers.

Miller plasma cutters are based on a novel technique which ensures fast and high quality works. They make use of highly pressurized air or other non-reactive gases. The gas is let out at high velocities through a nozzle and which creates an impact on the metal surface. Simultaneously, an electric arc is produced which is capable of converting this gas under high pressure into plasma. The high temperature plasma formed is capable of melting the metal at the desired point. Since the plasma is a semi-liquid it can clear off the molten metal from the metal surface after the cut.

This type of cutters can be employed for cutting almost any metal which has the ability to conduct electricity. It is to be noted that the efficiency of the work depends on the output power generated. The thermal dynamics causing the cutting effect varies from plasma cutters and the specific metal on which it is used.

Various metals require different quantities of output power. Further it is dependent on the metal thickness and the depth to which it should be cut. The cutting intensity can be manipulated by making suitable adjustments to the nozzle head and regulating the volume of air or gas through the nozzle.

There are three types of cut that can be delivered using Miller plasma cutter. They are known as quality cuts, sever cuts and rated cuts. They differ with the intensity of application and the quality of metal on which they are employed.

Since the power requirement for various metals are different, unique Miller plasma cutters are available for different metals. Using the exact type of plasma cutter recommended yields accurate flow characteristics which increases the cutting speeds and guarantees longer life for the plasma consumable set.

Miller plasma cutters are very user-friendly. They can be easily assembled for use. The basic operation to be performed is connecting the compressed air source and the plasma cutter.

As with all operations involving high temperature products and pressurized gases, proper measures for personal safety as well as protection for the Miller plasma cutter should be strictly adhered to.
