How to make perfect circles with plasma circle cutter?

History of Plasma cutting

In the 1960s, plasma cutting was known for their growth outside of the plasma welding, and it emerged in a very productive way in to order to cut metal and plate in the late 1980s. The advantage that it had over the traditional equipment was produced with no metal chips also creating a much cleaner outing surface which included fuel cutting.

The earlier plasma circle cutters were much larger and very high priced that it was slow and was known to keep on with cutting patterns in a productive way.

Computer numerical control technology was used for plasma cutting machines from the 1980s through the 1990s which gave the machines the flexibility to slash through shapes based on what was placed into the machine. Only two axes were allowed for these CNC machines and they were limited to a variety of patterns.

What is a plasma cutter?

A plasma circle cutter is the process where something cuts through materials electronically with an accelerated pace of hot plasma.

The materials that are being cut with the plasma includes copper, brass, stainless steel, steel and aluminum.

The process of plasma cutting is known to be used in concoction shops, restoration and automotive repair,construction and operation shops.

Plasma cutting is used rapidly within a large scaled industrial application to small shops due to an increased speed and cuts along with low cost.

Possible starting points

During the start of plasma cutting, they are provided with different ways in which they can begin their arc In many cases, this arc is designed to connect the torch with its work piece.

Sometimes cutters can use a high frequency voltage to start the arc. This process may have a few downsides including the struggle to repair, possibility of electrocution, spark damage and the frequency of radio emissions. When working by delicate technology, plasma cutters tend to start the pilot arc.

The wire and tap then gain a connection with one another. The nozzles blows forward after plasma begins to run down. An extraordinary method is the ejected liquid into the main circuit using the silicon rectifier.

What is the process of plasma cutting?

During the plasma cutting process, it requires one to create a channel from electrical specs of over heated ionized gas,plasma from the plasma circle cutter itself. The work that is placed to be cut forms a completed circuit back to the plasma along with the bottom clamp.

This process is established by air, oxygen and other materials depending on how much is being pierced, which is then focused on the increased amount of speed towards the piece of work being done. Next, an electrical arc forms within the gas.

Within an electrode, it's placed into the gas faucet and also through the work piece. Some of the gas is turned by electrical arc which manufactures an electrical channel plasma. As an electric spec moves down the plasma that's ample enough, heat is then melted and built in that particular work piece.

Most of the velocity from the plasma and the gas, is blown away from hot metal in order to cut through the materials. This specific type of cutting is a way of getting through thin and thick materials.

Equipment that is hand held can cut up too, 1.5 inches of thick steel and is very delicate and strong. Computer torches can cut up to 6 inches thick since plasma can produce a very limited and warm process to cut with. It's very convenient for cutting through sheet metal or even slanted shapes.

The Safety Procedures

Face shield and appropriate eye protection is necessary in order to prevent long-term damage to the eyes along with damage from any debris. A shade of 8 is required when one has the arc current that is below 300 A. In cases where the arc is actually hidden, it would be best to use a filter that is lighter.

Also to prevent heat burns from debris and any sparks, your attire should consist of an apron, jacket and even gloves with leather.

The Inverted cutters

More than 2 kilowatts is required by plasma cutters which uses a much heavier frequency. Inverted cutters resolves the main source of supply that is then given to the inverted transistor from 10 kilowatts to a total of 200 kilowatts.

Frequencies with much more switching assist with a small generator deriving from its size and reduction of weight. Transistors being used were those of MOSFETs, but now have a greater advantage using IGBTs.

If a transistor with MOSFETs operates then it can cause streaming matters of about a quarter in its inverter. IGBTs which are found in higher machines, does not have these failure issues.

Although with the more powerful and lighter switch mode, some plasma cutters, are not able to run a generator, especially those that do not have the correction of a power factor. Much newer models have the circuit that allows units to be used without an actual power factor in order to run on generators with light power.

Another cutting method

CNC cutting is yet another method for plasma cutters that allows an electronic computer to control its torch, which produces a decent and clean cut. CNC is built from certain plasma cutter manufacturers, some can have an actual cutter built in table.

The modern day plasma equipment of CNC have a compatibility of cutting with an axis through thick material that offers opportunities for welding equipment. For those that seek thin material, plasma cutting is in place by laser cutting because of the superior abilities of laser cutters.

The use of CNC cutters has been used in an HVAC industries. The software uses the information and then make a pattern that is cut on the table by a plasma torch. With this new technology, it has given productivity an increase in the early 1980s.

These cutters are also used to create metal work that are designed in workshops.
