An important tool in any metal fabrication industry is called as plasma cutters and they make clean cuts through metal. This welder uses high temperature so the user can cut the metal with accuracy and also it is one of the oldest welding machines that have been used since World War II. Now, this device has been made with some improvements and upgrades and also they remain a very effective tool. A plasma cutter uses a gas called inert gas and through electric current, it creates a powerful torch and it cuts the metal with ease. The gas is generally blown through the nozzle of the machine at a high speed and the gas that gets heated up converts it into hot plasma. The heat that comes out of the welder melts the metals as it cuts and enhances a smooth and clean edges.
This plasma cutting machine was first appeared in the American factories and then used in military aircraft production plants during the time of World War II. The working principle of the plasma cutter is simple and it works through the forcing gas from a narrow opening and then through electric current. Gases such as oxygen, nitrogen or air can be used and the temperature to which it gets heated up converts the superheat fuel into plasma and it is a different state of matter. As i said above, this is used in metal fabrication industry and also used by contractors who are in the outside field and it is easy for them to repair any onsite works and it avoids the use of carrying heavy welding machines. The plasma cutters are designed in such a way that it is portable and convenient to carry to different places. It increases the work speed and the users can finish their work soon.
This plasma cutting machine is used in different conditions and in different industries and especially the auto industries uses this welder for cutting out parts and then to make it into shape. Some of the heavy industries use this machine to slice through large sheets of metal and it is used by auto shops and locksmiths as a hand held tool when they need to make some bore. It is also used in a technological way and the cnc machines which is called as computer numerically controlled machines enhances the workers to use it on computer screen and the plasma cutting device follows the instructions as loaded in the cnc machines and perform the welding process as prescribed by the computers and performs automatic cuts.
This welding machine is also used by artists as a unique part in their metal work and the tip of the plasma cutting machine enhances them to make the intricate patterns in the metal. This welding machine is available in the market in cheap rate with best quality and many manufacturers manufacture it because it in more in demand and also, many welding shops sell this welding machine.
