Another very common thermal cutting technique is plasma arc cutting This process is based on an electrical arc between an electrode inside a torch and the workpiece A gas such as argon nitrogen hydrogen or air is injected into the arc inside the torch turning it into a plasma with a temperature of more than 10 °C

The confirmation test results indicate a reduction in Plasma Arc Cutting PAC process is a widely used machining process in several fabrication construction and repair work applications

Water Injection Plasma Arc Cutting – in this form of plasma arc cutting water is injected into the plasma arc giving it a substantial temperature boost via the gas nozzle to about 30 degrees centigrade and this can improve the quality of the cut provided Image shows the handheld plasma cutter Image by Tim Drivas on wikipedia

Plasma arc cutting can be characterized in terms of two different speeds At higher cutting speeds the plasma jet does not cut through metal plate At lower speeds the molten metal from the kerf sticks to the bottom of the plate so we have to optimize proper parameters Air pressure current flow rate

The plasma arc cutting process a can be used only on materials 6 4 mm W quot thick or less b can be used only on mild steel and stainless steel c is used on metals that are electrically conductive d is used mainly to clean up foundry spills

Plasma Arc Cutting Revision 2 0 September 1 2 Plasma Arc Cutting Accurate cuts can be made in stainless steel and non ferrous metals such as aluminium by plasma arc cutting The cuts are made by a high temperature high velocity gas jet generated by constricting an arc between a tungsten electrode and the component

INTRODUCTION TO CNC PLASMA ARC CUTTING Chapter 1 13 EARLY PLASMA CUTTING The plasma arc cutting process saw its first commercial application in the early s Early plasma cutters were large slow and expensive Consequently common applications for PAC consisted of repeating cutting patterns in a mass production mode

Plasma arc may be used for either cutting or welding and is the most widely used thermal process for cutting of aluminium alloys in manual mechanised or fully automated modes Fig 4 1 In the latter case cuts of excellent quality can be achieved in material of up to mm thickness at high cutting speeds

Plasma arc cutting PAC What cutting process uses a stiff highly ionized extremely hot column of gas to almost instantly vaporize metal being cut List 3 factors that can help determine which welding process to select for a certain job

plasma arc cutting PAC Most cases faster and more efficient than any other cutting method PAC Advantages cuts ferrous and nonferrous produces minimal dross minimal heat affected zone little or no distortion possesses high cutting speeds produces very narrow kerf safety

The term for advisable state of plasma arc is called stability of arc too The stability of arc is keeping the plasma jet in desired form It is possible to be provided by 4 Fig 2 The principle of the plasma cutting shape of plasma torch streaming jet water We must monitor these parameters temperature and electrical

During plasma cutting the range of cutting speed – mm min arc voltage – V plasma gas flow rate – l h shield gas flow rate – l h is selected for HTPAC process From analysis it is found that arc voltage is the major influencing parameter for controlling the plasma cut quality

Mar 18 Main Arc Generation – the next step is to ignite the arc and ensure that the electric arc is formed between the electrode within the plasma cutting machine and the workpiece itself and at this point cutting begins and at the same time if two plasma gases are required the shield gas will start to flow to hone the cutting flame

Aug 07 A plasma arc is a much bigger version of the same thing with a gas such as oxygen nitrogen or argon blowing through it to create a kind of super hot plasma torch like a giant welding torch Artwork How a simple plasma torch plant works

1 0 0 PLASMA ARC CUTTING PROCESS Plasma arc cutting is such a simple process you could almost take it out of the box and start using it However as with any piece of equipment you need to know how and why it does what it does and the necessary precautions to do the job safely

Plasma arc cutting is based on the establishment of a direct current arc between a tungsten electrode and the surface of a conducting metal The arc is created by ionizing a gas plasma gas and then blowing the ionized plasma towards the surface of the workpiece in order to form a conductive pathway down which the main plasma current passes

Mar 30 Plasma arc cutting is a high precision method of metal cutting using the ionized state of plasma gas Plasma is capable of conducting both energy and heat and when it is combined with compressed air and shot through a small orifice such as a nozzle it performs top quality and precision cutting

8 Avoid cutting with the plasma arc cutter in damp or wet locations The hazards of electrical stock greatly increased 9 If plasma arc cutting over an open barrel with a grate be aware that the fume plume will be directed back toward the operator Avoid this condition if at all possible otherwise limit the exposure to fumes to short

Apr 18 April 18 Business Plasma technology has so many spheres of usage today However it is the industry where we can most often see its application Plasma cutting is one of the most used laser cutting techniques today It finds particular use in smaller workshops and with the development of technology – systems that allow for

An electrical power supply and a cutting gas What are two sources of power are required for a plasma arc cutting process By passing the gas through an electric arc inside the torch How does a PAC plasma arc cutting torch convert the cutting gas into plasma 30 degrees F or higher

Educational information and quizzes covering a variety of welding topics – basic electricity welding processes and filler metal selection

Plasma Arc Cutting PAC Cutting process that melts a localized area with high velocity gas Plasma A fourth state of matter distinct from solid or liquid or gas and present in stars and fusion reactors In plasma cutting is formed when an electric arc heats and ionizes a stream of high pressure gas Slag

Apr 08 The principle of plasma arc machining is shown in the figure In a plasma torch known as the gun or plasmatron a volume of gas such as H2 N2 02 etc is passed through a small chamber in which a high frequency spark arc is maintained between the tungsten electrode cathode and the copper nozzle anode both of which are water cooled
