Plasma Cutting Systems

Let us see how plasma cutting systems work? A gas is released through a very narrow opening, thereby increasing its high pressure. Before the gas escapes, an electrode is placed in its way that passes an electrical current through the gas. The gas atoms on being stimulated by the electric current produce positively and negatively charged ions. These ions collide with each other and the rest of the gas atoms to produce more ions. In no time, the gas reaches a superheated state or plasma.

Plasma cutting systems are nothing but an electrical circuit that have an electrode acting as a negative terminal (cathode), and the metal sheet to cut, acting as the positive terminal (anode). The plasma jet is attracted towards the metal sheet and at this point, in the operation, can focus as much as 30,000 degrees Fahrenheit or 16,648 degrees Celsius of heat on the metal sheet and melts it. The narrow opening of the nozzle increases the pressure exerted by the gas which also blows away the melted metal, thereby aiding the cutting of the metal sheet. The plasma arc is kept thin and controlled with the help of shield gases.


A plasma cutter is provided with channels to release shield gases which exert pressure and control the plasma arc and keep the plasma jet directed on the metal sheet. Inert or semi-inert gases are used as shield gases to shield the area, where the plasma arc or jet touches the metal. The plasma cutter is also known as a plasma torch. Plasma cutting systems are available as manual and computer-controlled. Let's take a brief look at the latter type.

Knowing Plasma Cutters; How They Work

If we look at the modern industry, we see that it mostly depends on the management of heavy metals and alloys. Metal that is used to create tools and transport required for day-to-day business. Devices in daily life, much to do, including cranes, cars, skyscrapers, bridges, robotics, and suspended metal parts that occur precisely This is because the metal is very sturdy and what will be big and strong, metal is the perfect choice.

Because the metal is so strong, it is very difficult to cut and revised it desirably because of the strength of the metal will not be able easily to form a special piece. There are plasma cutter to use great for cutting metal. Plasma cutters work by binding one of the most common state of matter in the visible universe; Plasma Cutting Machine Plasma comes in all shapes and sizes vary. Cutting metal is tremendous as the blade plasma portable.

Cutting Plasma is basically quite simple and easy to use cutting tools, steel and metal conductive with other electrical work of cutting, plasma is made by using high voltage R. and compressed gas, which is usually air. R. concentrations of plasma is created at the tip of the blade as the electric arc ionizes the gas from power through the nozzle. Circuit has been developed into a high arc in contact with the surface of the work is less soluble than 1 / 16 "Wide. The power of plasma, and then blow out of the area on the specimen failed completely. So clear cut that to happen. Without any scale. The speed at which travel through the nozzle, plasma arc will be up to 20,000 feet per second and reach temperatures as high as 30,000 degrees Fahrenheit.

Talk about the energy used by the plasma cutter will be seen that fire plasma cutter, portable 110-volt use in the production of about 12-35 amps in compressed air. Boards are usually found on these machines to simplify the use of them. Blade plasma large are out between 50 and 80 amps and they are a 220-volt system for cutting metal or other conductive up to ½ inch thick, plasma. Mobile devices are available off. However, in a large-scale industrial use of people who can cut through 2 inches of metal.

Very useful to use plasma cutter in Welding Industry. One of the main advantages of the plasma off the surface of the metal cut out of the area is still quite cool. This will help prevent damage and color curve that occurs with other flame cutters for cutting accurate curved lines are hot, some areas are affected (HAZ) also allows the use of templates. Since plasma does not require gas is highly flammable, they have the ability to reduce the period of five to faster than Torches traditional sometimes acts as a cutter, plasma gougers and the ability to cut metal with. accurate and fast.
