The Basic learning of Plasma Cutting

The basics of plasma cutting are not so intricate, but not so simple as well. You have to have some basic requirement or knowledge for plasma cutting. Plasma cutting is the best for occasional repair and maintenance work. From higher cutting volumes to lower cutting, all these circumstances serve great reasons to investigate plasma cutting.

Some basic learning of Plasma Cutting

Plasma Cutting Technology​

​Technological advancement is covering up the entire world. Today the entire world is tied upon with technology. Machine cost is getting lower, machines are getting smaller sized than before, portable machines haveprevailedthe market and technology is offering increased favors and easier usage. It is time to take a serious look at plasma for cutting applications. The advantage of plasma cutting comprises ease of use, higher quality cuts and quicker travel speeds. Plasma cutting is being used in the cutting of conductive materials like metals, steels and copper. It utilizes electrically conductive gas to convey energy from an electrical power source during a cutting torch for cutting the material.

How Plasma Cuts through Conductive Materials

The fundamental plasma arc cutting process comprises of an electricity supply, an arc starting circuit and a torch. This system providesthe power energy, ionization capacity and process regulate that is essential to generate high quality, immaculate quality efficient cuts on a diversity of different conductive materials. Steady current DC power source is the power supply. The circuit voltage is generally maintaining the range between 240 to 400 VDC. The amperage of the power supply decides the speed and cut thickness capacity of the system. The prime role of the power supply is to deliver the right energy to sustain the plasma arc after ionization. The circuit of arc starting can generate an AC voltage of 5,000 to 10,000 volts at approximately 2 megahertzbecause it’s an elevated frequency generator circuit. The voltage is being used to make a high acute arc inside the torch to ionize the gas, by this means generating the plasma. The torch disseminates as the holder for the consumable nozzle and electrode and serves to cool either gas or water to these parts. The plasma jet is maintained by the nozzle and electrode constrict.​

Comparison between Plasma Cutting with Oxy-fuel Cutting

Plasma Cutting can be practiced on any type of conductive materials. Examples can be- mild steel, aluminum and stainless are to be counted as conductive materials. Mild steel can be cut smoothly and fast than with alloys. The metal or steel which is severing or oxidizing or Oxy-fuel cuts by burning. So, in this case, it is limiting the ferrous and non-ferrous metals which assist the oxidizing process. Aluminum and stainless steel are needed to be further oxidization. For working, plasma cutting does not depend on oxidation, and so that it can cut stainless steel,aluminumor any kind of conductive material. Various gases can be used for plasma cutting for conductive material. Compressed air is the best fitted for plasma cutting. Many users have used compressed air for the plasma gas. In many shops compressed air is available, so alternate fuel gas and compressed oxygen are not required for operation.Plasma cutting is generally much easier fromapprentice to expert people to operate, but it needs sometimes cope up with in that process. Oxy-fuel cutting is not faster or quicker than plasma cutting. So, plasma cutting is better than oxy-fuel cutting.For massive or gigantic sections of steel like 1 inch or greater, oxy-fuel fits well, since oxy-fuel is generally faster and for weighty plate application. The power supply needs to be highly capable for plasma cutting operation because it needs more energy to cut massive conductive materials.

Ideal Plasma Cutting Of Steel

1-inch thick and less than 1 inch conductive materials are fit for plasma cutting. This is basically the perfect size for plasma cutting. The operator needs to be carefully regulating the cutting speed so as to maintain the oxidizing process for oxy-fuel cutting. Plasma cutting is more forgiving in this regard. Plasma cutting really glows in some niche applications, such as cutting enlarged metal, which will not have happened in oxy-fuel. Comparison to a mechanical mean of cutting, plasma cutting is frequently faster and more accurate and can promptly make non-linear cuts.

Obstacles to Plasma Cutting

This apparatus of plasma cutting is comparatively expensive than oxyacetylene. Oxyacetylene does not need any access to electrical energy or power or any compressed air, which is preferable for some users. Oxy-fuel can cut thicker sections (greater than 1 inch) of conductive material. It cuts more easily and promptly than plasma cutting.

Swirling Gas Enhances Cut Quality

Plasma gas needs to be swirled, if it is not then, consequences would be slant from both sides of the cut. Gas swirl can make the arc disseminate evenly along one side of the cut. If the swirl is inverted direction, the square side will switch. Ionized gas is swirled, so the electrical arc will automatically attach itself. Multiple attachment sections more even a power disseminate through the workpiece. Basically, there are three major ingredients inside a torch body which are: Electrode, gas baffle, nozzle.


The basic of plasma cutting is very easy, simple and convenient.

The user needs to have a little bit of understanding the apparatus of using it properly.

Plasma cutter is very advanced and portable products for cutting conductive materials effectively and efficiently.
