Save Your Welding Time through Plasma Cutter:

Tuesday, December 7th, 2010

If you are going to cut heavy steel or any other kind of industrial-sized material, you could integrate the use of a plasma cutter. This weld technique can slice such thick and complex metals with ease and precision, unlike any other. This technique can slice metals, very smoothly imparting a professional look, overall.

In general plasma cutter has got its name from the plasma that is produced by the heat which comes from the torch. This torch will in turn heat up the gas, to a certain level from where the electrons will begin to separate from their nucleus.

This generates a huge amount of energy, whereby such energy will instigate to ionize the atoms imparting it with the plasma. Plasma cutter can be exploited to slash very large pieces of metal and steel. There are quite a few different types of industries that generally use this type of mechanism or device on daily basis.

You can see this mechanism working in HVAC industry, where individuals are labor with refrigeration and heating/cooling products. You can also spot them in the hands of several plumbers when they are out for their daily duty. With plasma cutter it is for sure that you are going to save your time as well as save your money.

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.

What Is An Air Plasma Cutter?

Thursday, March 26th, 2009

The air plasma cutter uses plasma, a completely different state of matter compared to solids or other gases, to cut material. This form of cutting is very durable and clean. This cutting system is said to be awesome for use within an industrial setting, even if a large amount of repeatability is needed. (more…)

An Overview of Plasma Cutting

Tuesday, January 6th, 2009

Plasma is considered the fourth stage of matter because it happens when high heat is applied to a gas. The first stages of matter include ice, water and steam (gas); when you continue to heat the steam it turns into plasma. Plasma is used to cut metals that need a very high heat.

To do plasma cutting the welder must have a plasma torch and it is often used through a machine. Usually a plasma cutter is used when steel and other metals have to be cut. Within the plasma torch an inert gas is blown out of the nozzle at a very high speed. As this continues it forms an electrical arc that travels through the nozzle to the surface of the steel that the welder is cutting which turns the gas into plasma.

Because plasma is very hot it can easily cut through metal and because of the way the process works it blows any melted metal away from the cut. This makes it very convenient for the welder because they do not have to clear away metal the way they would in other types of welding.

There are two types of plasma cutting:

HF Contact — in some machines to cut overall cost you will find this kind of plasma cutter process. It uses a high voltage spark at a high frequency to ionize air. The process moves through the torch head and then when the torch comes in contact with the material it create an arc. This type of machine is limited and it will not cut any CNC application.

Pilot Arc–this type of plasma cutting uses two cycles that produce plasma for cutting. The body of the torch produces a high voltage, low current circuit that starts a high intensity spark. This generates a small pouch of plasma gas that is referred to as a pilot arc. The head of the torch has an electrical path return built in. With these two mechanisms the pilot arc is held back until it hits the metal to be cut. As the plasma and the metal come together the main plasma arc is ignited and the cutting is done.

New technology has created a plasma torch with a smaller nozzle which makes the plasma arc thinner. This gives the plasma the ability to make a cut that is comparable to a laser.
