Plasma can be simply defined as the fourth state of matter after the three commonly known ones that is solid liquid and gas. What brings difference between different states of matter is the quantities of energy inform of heat that each holds. In the event that additional heat is added to a certain state of matter, there will be a significance change in its physical appearance and behavior.For instance is energy that is in form of heat is gradually added to ice, it will definitely turn into water with immediate effect. If we continuously add more heat energy to matter in steam form, gases involved get ionized as first as possible and as a consequence of the later process all the ionized gases become electronically conductive which is what is known as plasma.
From the above description, we can then learn that plasma cutting is the process of cutting different metals with varied properties in terms thickness and composition such as steel and iron using a special technology commonly known as plasma touch. During this process, a compressed inert gas is usually blown at very high speed through a small nozzle while at the same time an intensive and very strong electrical arc is formed and pointed at the surface of the metal to be cut. The reason behind be ability of plasma to cut very thick metals very first as it does is because it has very high temperatures that enables it to melt metals and blow away all the melted portions of that metal from that cut. On the other hand, plasma cutting machines are the equipments that do all the above function.
Metals are known to be very strong and durable and that is reason why things that are meant to exist for a long time or do some heavy tasks are made of them. Almost all modern industries and factories today rely solely on the use of heavy metals and their alloys. Metals are much need to manufacture all the relevant tools that propel the economy of the world. For instance, vehicles that are our major means of transportation are entirely made of metals. All the machines used in our industries such as sugar milling machines are all products of heavy metals. Even when it comes to building and construction such as bridges, houses and railways, we still need metals. That is why plasma cutters really play a major role in human industrial development.
The emergence of plasma cutting technology has completely revolutionized metal industry. The plasma arc emphasizes on accuracy, speed and it also offers all the possible cuts metal manufacturers would want. The indispensable plasma arc is a cutting system that comprises of an arc starting circuit, a touch and a power source which basically provides the electrical energy needed to ionize metal atoms during cutting process. Theoretically, we can boldly say that plasma cutting machine is a very simple equipment that get does its job within no minute by using the technology offered by a state of matter that is considered as one of the most rampant in the world.
An air compressor is a flexible tool which converts power into kinetic energy by compressing and pressurising air and is also known as a pneumatic tool. Air tools are more durable, faster and lighter as they have more torque and power than other conventional power tools. A portable air compressor is ideal for the home and job site usage whereas in the case of stationary compressors the high volume of air needed for powering automotive and production air tools are provided.
There are a variety of compressors available in the market according to their needs as they are used to supply high-pressure clean air to fill gas cylinders, moderate-pressure clean air to a submerged surface supplied diver, moderate-pressure clean air for driving some office and school building pneumatic HVAC control system valves, a large amount of moderate-pressure air to power pneumatic tools for filling tires and to produce large volumes of moderate-pressure air for large-scale industrial processes such as oxidation for petroleum cooking or cement plant bag house purge systems.
For a selection of perfect compressor for proper working, some factors should be considered. For example, Portability; Stationary or portable, Power Source; Electric or gas-powered, Performance Ratings; SCFM, PSI and horsepower. Moreover, horsepower is the unit of measurement for the power a compressor’s motor produces. Higher horsepower engines produce greater PSI and are able to carry a heavier workload. Tank Size ; No tank, small tank or large tank, the units with more powerful motors and larger tanks (measured in gallons) can generate higher levels of PSI for longer amounts of time, providing greater power to the air tools, CFM: cubic feet per meter -this is the volume of air that your compressor can pump in one minute, a specific working pressure.
High CRM ratings mean a compressor can provide more air making higher CFM units more practical for larger applications. PSI power per square inch is the measure of air pressure delivered by your compressor. The higher the PSI, the further the air can be compressed – means a larger volume of compressed air can be stored in the tank interconnecting piping. Selecting an air compressor with rigid piping and flexible connections will ensure that there will be no leaks. Pump Type ; Continuous operation, stop/start operation, single stage, two-stage, oil-lubricated and oil-free motor to compare the brake horsepower to nameplate rating.
Motors that go into the service factor are not at all reliable and should be avoided. Electric power source to air compressors is preferred in case of household needs at a voltage between 110;120V because electric air compressor doesn’t emit fumes, it is the best choice for indoor applications.
On the other hand, Gas-poweredair compressors are generally used by builders and re-modelers because they provide high output and convenience at the jobsite and emit exhaust, so should be operated only outdoors, where proper ventilation is available. These generally have horsepower ratings between 1.5;6.5 HP. Stationary oil-lubricated compressors with a rating above 2 HP require a 230/240v power source to supply the high volume of air required for high consumption air tools like sanders, grinders and sandblasters. Air compressors with air cooling system should be preferred as they cool the pumping machinery and extend motor life.The Thermal Overload Switch can be used in a good air compressor to automatically shut off the motor if it overheats, increasing tool life and protecting your investments.
Laser cutting devices are designed for power and precision giving you an economic advantage. CO2 laser cutting machines guarantee optimum results by reducing the total work time.

Moreover, these cutting devices increase production quality. In order to attract customers, quality service delivery is essential. Materials that are cut with laser machines are of the highest standards with no cutting deformities. The cutting is precise, spotless and silent. These machines have beam light that focuses on extremely small surface area of between 0.1 and 1 mm in diameter.
Another aspect with these machines is that the area in proximity to the cut edges is not altered by heat. At times, you need to cut the material in complex shapes and this is where CO2 laser cutting machines come in handy. The machines have the ability to operate in complex profiles and can produce very small rays of curvature. The beam light does not exert mechanical pressure on the material meaning that there is absence of wear.
You can use the machine to cut materials independent of hardness meaning you will obtain almost the best quality in virtually all materials, which you cut. Whether it is coated, surface treated materials or different materials like plastic, wood and metal, you will get satisfactory results. The machine can easily be integrated with other automated systems giving you flexibility in obtaining the results you want.
If there is sudden change in production needs, you can as well adjust the machine to deliver to expectations. There are times when you have increased workloads that you have to accomplish.

CO2 laser cutting machines can reduce the costs of production because of the high-speed cutting.
In addition, since the machine produces finished pieces of materials that do not require further processing like finishing, polishing or de-burring, this certainly reduces the amount of time taken to complete the work. You can achieve greater workloads without necessarily increasing the manpower further maintaining the costs of productions at low levels. Different materials like plastic, wood, and metal can be cut with this machine.
The machine allows for clean cuts of thermoplastic materials with polished edges. The absence of stress and deformation of materials ensures that complex shapes are cut at very high speeds. Polyesters and polycarbonates may also be cut precisely with the tool. Natural synthetic rubber with thickness of up to 20 mm could also be cut with use of medium intensity CO2 laser cutting machines. Woodcutting can be achieved with good results and uniform grooves throughout the entire length of the piece.
The CO2 laser cutting machines can be used in marking and cutting of inlay wood pieces making them ideal for handcrafts, interior wood furnishing, and gift items design. As with paper material, it is easily cut with use of low power laser machine. In spite of the high levels of surface reflectivity in metals, the laser beam causes superficial fusion, which in turn induces a cutting process. However, not all metals are cut with the laser beam.
