2 0 Gas Selection for Plasma Arc Cutting 2 1 Plasma Cutting Gas Selection Selecting the proper gas for the material you are cutting is critical to get a quality cut Functions of gas in Plasma Arc cutting Plasma gas is also called the cutting gas This is the gas that is ionised in the plasma process and exits through the nozzle orifice See why people prefer PlasmaCAM& 39 s affordable CNC Plasma Cutting Table This is the best plasma cutting machine for creating metal art custom auto parts or any other metal shape you may need!Nov 16 The plasma arc is now widely used in the steel chemical and mechanical engineering industries As market leader in this sector Oerlikon has turned it into a powerful cutting and welding tool It is generally accepted that the plasma welding process is the major technological advance from inert gas shielded free arc welding the TIG process Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot ical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as well Some of the plasma arc cutting options available include In conventional plasma arc cutting the plasma cutting equipment includes the plasma torch assembly which utilizes a single plasma gas serving as both the ignition gas and the cutting gas Typically the standard process employs nitrogen oxygen or a hydrogen argon mixture Arc Cut Pro Overview Take your shop& 39 s production to the next level with an Arc Cut Pro Plasma Cutting Machine Our machines combine an advanced controller with an industrial quality platform to meet the toughest demands of steel shops across the country We offer water and downdraft table options as well as custom table sizes Swirling gas improves cut quality If the plasma gas is not swirled results would be a bevel on both sides of the cut By swirling the gas the arc is distributed evenly along one side of the cut If the swirl is reversed direction CW to CCW the square side will switch 1 Plasma Arc Cutting Torch 2 Tool & Workpiece 3 Gas supply unit 4 Cooling Mechanism 5 Power Supply unit 1 Plasma Arc Cutting Torch A plasma cutting torch consists of tungsten electrode fitted in small chamber The electrode is given to negative terminal There is small converging nozzle at the end of torch 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

Cut Direction must be considered when programming the plasma cutter Like a router the direc tion of travel the plasma torch takes will affect the cut quality This is because the holes in the swirl ring produce a swirl in the plasma jet The finish side of the plasma cut is the right side of the cut when facing the direction of travel 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 AMICO POWER 50 Amp Non Touch Pilot Arc Plasma Cutter 4/5 in Clean Cut 80% Duty Cycle 90 Volt to Volt Wide VoltagePlasma Cutting PAC Plasma Cutting PAC is an electric arc cutting process that severs metal by melting a localized area with a constricted arc of super heated gas which melts the base material at high velocity The plasma torch has a recessed electrode which uses electrical energy to heat the gas which may be air nitrogen or oxygen Since plasma cutters produce a very hot and very localized " cone" to cut with they are extremely useful for cutting sheet metal in curved or angled shapes How are the arcs generated It usually starts the arc without contact with the workpiece in a three step process A high voltage spark briefly ionizes the air within the torch head During the arc initiating period of plasma cutting an inert gas or compressed air was blown out of the torch nozzle toward the workpiece A pilot electrical arc forms and ionizes some gas thereby creating a plasma channel capable of conducting electricity and providing a circuit As plasma gas i e the monatomic argon and/or the bi atomic gases hydrogen nitrogen oxygen and air are used These plasma gases ionize and dissociate by the energy of the plasma arc By recombination of the atoms and molecules outside the nozzle cathode system the received energy is suddenly set free and intensifies the thermal impact of the Feb 02 Argon hydrogen is the gas of choice for thick stainless and aluminum cutting > 1/2" The mixture typically used is 35% hydrogen 65% argon H 35 Argon hydrogen is the hottest burning plasma gas and provides the maximum cutting capability Argon hydrogen is used in water injection torches up to amps for cutting up to 6" stainless
