Plasma cutting machines versus oxyfuel cutting
Monday, August 9th, 2010Plasma cutting has constantly been compared to the oxyfuel cutting. The plasma cutting method is usually performed on any type of conductive metal like mild steel, aluminum and stainless steel are some examples. The welders are able to experience faster, thicker cuts with mild steel than with alloys. On the other hand the oxyfuel cutting is done by burning or oxidizing the metal it is serving. Hence it is limited to steel and other ferrous metals which supports the oxidizing process.
Oxyfuel cutting is not possible for metals like aluminum and stainless steel because they form an oxide that inhibits further oxidization. Here plasma cutting works since it does not rely on oxidation to work and thus it can effectively cut aluminum, stainless steel and any other conductive material. Usually air plasma cutter uses compressed air even though different gases can be used for the process. Compressed air is readily available in most of the stores so there is no requirement of fuel gas and compressed oxygen for operation.
Yet another advantage of plasma cutting machines is that it can be easily mastered and is typically easy for the novice to the experts. On thinner materials the plasma cutters have proved to be faster than the oxyfuel cutters. However for cutting heavy sections of steel say one inch and greater, oxyfuel cutting is still preferred as it is typically faster. Moreover very high capacity power supplies are required for plasma cutting applications which are not always available.
Short information on CNC plasma cutter:
Thursday, July 22nd, 2010Plasma cutters are known for cutting metals which are seen from a long time. Now with technology the CNC plasma cutter uses computer coding for cutting. This cutter uses a special program called G code for coding commands. Therefore, the productivity increases by 100 %. These are inexpensive and are more advanced than before. These are the most efficient cutters and can supply the metals to the distributor on time. These are considered to be the most powerful tool among the welding equipments.
These have the ability of cutting the whole metal in one shot. Since these are computerized the performance and productivity of a company increases. These are also used for cutting broad and thick metals. The maintenance cost is also less than the other plasma cutter. The cut of the metal by CNC plasma cutter is flawless and efficient. These come in many varieties and shapes which are used for cutting different size of metals.
Five tips to avoid problems in plasma cutting
Monday, July 12th, 2010For alleviating many troubles during plasma cutting, it is essential to take careful preparation, setup, and maintenance. Following are five things that would help you to avoid some of the common problems while handling plasma cutters.
Replace consumable parts regularly: it is much more effective to replace the consumables regularly than replacing the torch. Torch failure may happen if you are using severely worn consumables which can lead to uncontrolled arcing in the plasma chamber.
Assemble the torch properly: with correct care, torches would last for a long time. A properly assembled torch would ensure that the parts are in alignment and fit together snugly.
Use parts for the job correctly: check the operator’s manual that defines which consumables are appropriate for various types of cutting. If you use incorrect consumables, the life would be less and cut quality would be reduced.
Ensure coolant flow and gas accurately: it is important to check the flow and pressure of gas and coolant every day. For maintaining the cutting arc, constant gas pressure is important.
Avoid excessive application of lubricant: use just enough O-ring lubricant to put a shine and not more. Make sure to remove shields before putting antispatter compounds on them.
How are plasma cutters useful?
Tuesday, July 6th, 2010Plasma cutters are seen from more than 40 years which useful for cutting metals. It is said that these are very easy to work with and cuts metals better than other welding equipments. These are very effective for cutting due to the latest technologies. These are bit expensive and are easy enough to understand at one time. The benefits of these cutters are essential and enhancing tool for productivity. These are also known for high cutting speed and for good quality. Due to the speed it saves lot of time and money but gives double production. Once the metal is cut it doesn’t require preheating of metal again.
These are used for cutting any kind of metal with any thickness. But these need high voltage power for cutting metals. These can cut, pierce and bevel all kind of metal in different shapes and size. You can change the function of this cutter from hand to automate. The main advantage of plasma cutter is the inner part of metal remains cool. Just because they don’t relay on any high flammable gas these tend to cut the metal more than 5 times faster than other cutting or welding equipments.

Plasma cutters the child of modern invention
Thursday, June 17th, 2010Plasma cutter is one of the modern inventions in welding equipments. Plasma arc process has its origin 50 years ago its properties are it can ionize the materials and uses the inert gas to protect weld from oxidation; it works by sending an electric arc through a gas. Plasma cutting machines exists in different sizes and it is also called as a shape cutting machine. These plasma cutters used to cut different types of metals in different shapes. cnc plasma cutter is used to cut artistic metal shapes and parts. Plasma cutter uses consumables such as arc tig and mig welders. Plasma cutter has a special feature of torch operation in it. Plasma cutters are cheap and portable. Air plasma cutting has the special feature of cutting ferrous and non ferrous metals with no heat effect and no adjustments of oxygen or time required. Many types of plasma cutters are there and an online shop offers best plasma cutters with affordable prize.
Affordable Plasma Cutters for Private Use
Monday, June 14th, 2010It was not very long ago that plasma cutters were also expensive to buy for your own fun and activity. These days you can find a plasma cutter that will do almost any of your workshop cutting for approximately $1,000. Of course, the more money you spend on your plasma cutter then superior the unit will be.
The Firepower 12 amp plasma cutter, which comes by its own air compressor (compressed air is used to create the plasma for cutting) will run you $998.75. This part will cut through an eight of inch thick steel at a rate of nine inches per minute. You will not break any records at that speed, but it is still quite good.
If you desire to expend a little more coin you can pocket a Lincoln Electric Welders Century 25 Amp Plasma Cutter for $1,350.00. This plasma cutter was planned for auto body repairs and its arc is fully earthed so that high regularity harmonics that can damage car electronics are filtered out. Keep in mind, plasma cutters are not the gentlest machines in the world. They have a tough job to do and they are not troubled to let you know that they are doing it. Plasma cutters can generate sounds waves to the tune of 120dB; by evaluation, the engine of the 747 at liftoff is 140-160dB.
What are the usages of plasma cutting machines?
Wednesday, June 9th, 2010
The plasma cutters are mainly utilized by the construction people for cutting metals. The plasma cutting works only with electricity and some gases. These are used and seen from World War II. They can also cut heavy metals in lesser time. These are highly conductive than any other gas. The metal is cut when a high temperature of stream melts the metal and it is separated with high velocity.
The plasma cutting machines are used major in manufacturing car and other vehicles. They are also used by Construction Company for cutting metal sheets and large beams. One of the biggest advantages of plasma cutting machine is that the surface of the metal remains cool which prevent from damaging while wrapping. It can cut metals in different shapes and also used for penetrating holes.
Now you can get fully automatic cutter known as CNC. The full form of CNC is computerized numerically controlled cutters. These are generally seen at large scale industries and can cut thick metals. You can now cut the metal vertical with help of this machine.
