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.
Introduction about welding accessories
Wednesday, July 28th, 2010Welding is a process of joining metals, to join these metals the basic need of a welder is welding guns and torches. They are the light to welding industries and a basic accessory in welding process. Welding torches have the connections for the gas to flow through which flame forms and it is used to weld the metals. Welding gun has a number of key parts such as control switch, gas nozzle, and power cable and it consists of nozzle in which shielding gas flows and the torch is used to produce the flames. The welding guns and torches should have the facilities of extension of wires and the Spool guns are the guns which allow easy access and change out of wire in seconds. Plasma cutting torches is used to cut the metals and it is similar to welding torches, but can be easily identified. The plasma torch generates the plasma, which flow from it nozzles and each of the welding process has its own accessories and the welder should have a great control on handling these accessories.
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.
Plasma Cutter Is A Tool To Cut Metals
Monday, May 24th, 2010Transportable, light plasma cutters make use of 110 volts, through an amount produced of approximately 15-40 amps. In order to make things easier and to make simple usages, these plasma cutters repeatedly featured with involved air compressors.
The exterior of the metal on the outside of the cutting area remains calm and that is one of the major benefits of utilizing a plasma cutter. This put off the twisting and paint harm that can take place by means of other fire cutters. A thin HAZ (heat affected zone) also permits to utilize the models for exact curved stripe cutting.
Larger cutters will come with a productivity of approximately between 50 and 80 amps and they are 220 volt systems. An industrial plasma cutters will be able to cut metal up to 2 inches thick (5cm), whereas a hand-held model can be utilized to cut conductive metal which is ½ or (1.25cm) inch thick.
The Untold Secrets About Plasma Cutter
Wednesday, May 12th, 2010Plasma cutter is very easy to use. It is a machine that can be managed without any trouble. There are lots of varieties of steels and metals that conduct electricity and can be cut by this plasma cutter device. Non ferrous material and steel which is quite thick or less than 1 inch thick can be cut with the help of plasma cutter. Nearly all the varieties of conductive metals like aluminum, stainless and mild steel can make use of the plasma cutter.
By employing an electric arc and gas such as oxygen, air or nitrogen, this device starts function, by means of a slim hole. This entire process put together formulates the high temperature of gas which rises up to the level, and it attains the fourth state of substance that is called the plasma. The gas surpasses by the side of the nozzle and with the help of an internal electrode that gas is ionized. An internal electrode is the one which makes an electrical arc. At the tip of the cutter the strong plasma arc is created by this arc.
Power Supply System on plasma cutters
Tuesday, May 4th, 2010In addition, plasma cutting machine power supply normally includes: a main inverter circuit, the electric energy supplies in an arc on the plasma-plasma torch, and set fire to with a constant power supply, DC-loop, a circuit for generate high frequency superimposed on a high voltage to a direct arc between the electrode and nozzle of the plasma torch in the output voltage of the main circuit, a circuit that the output voltage of the main circuit between the electrode and nozzle, through the pilot-arc ignition and then makes the stage of the application of the output voltage between the electrode and the work piece so the pilot to create an arc main arc and a power control unit to the main switch, the circuit of circuits with high regularity and the pilot controlling the pilot arc, rotate and subsequently maintain the central arch supports.
Know that the CNC plasma cutter Power Device that these basics are usually restricted in a single chassis contains. Even though the main arc power is supplied by this kind of equipment for plasma cutting power depends on the type of material being cut and thickness, etc., can get to a high value, as several hundred amperes. It is therefore essential to create a circuit with high output capacity.
Tips To Maintain Plasma Cutter Torches
Monday, April 26th, 2010When you need a perfect cut, it can be easily attained with the help of a plasma cutter, but when you are a newbie, then you will have to follow some tips until you get used to the whole process properly. If you like to get the best cut and not waste a good piece of metal then follow a set of plasma cutting tips to save your metal as well as the plasma cutter machine.
A common tip for people applying O-ring lubricant is to use only needed amount so that you can see enough shine on the O-ring. It is important that you will have to remove the shields before adding anti-spatter compounds on it.
All you have to remember is that a lot of both materials will dirty the torch, which will result it early torch failures. Same way, grease or other any other such lubricants must not be applied to torches, this will again give problems to torch, as torch don’t need any lubrication. On the other hand, lubricants are good conductors of electricity and this can again damage the torch.
Tip to Avoid Problems in Plasma Cutting
Thursday, April 15th, 2010Plasma cutting is one of the most efficient and easy ways to cut a metal of any thickness neatly just like how you must have calculated.
