Plasma Arc Cutting Diagram

This increases the temperature and velocity of the plasma emanating from the nozzle.

Plasma arc cutting diagram.

The plasma arc formation begins when a gas such as oxygen nitrogen argon or even shop air is forced through a small nozzle orifice inside the torch. Powder wire or rod and propelling the molten material on to a substrate to alter its surface properties such as wear resistance or oxidation protection. So it acts as a cathode. The temperature of the plasma is in excess of 20 000 c and the velocity.

Plasma arc welding is a substitute of tig arc process offering greater welding speed and better weld quality for welding thin metal section current at 0 1a below the range of the tig arc. Parts working principle advantages application and more. The plasma arc cutting process cuts metal by melting a section of metal with a constricted arc. Operating instructions and parts manual plasma cutter description the plasma is an igbt inverter plasma cutter with thermal overload protection a trafimet torch and a built in gas regulator.

This electrode is connected to the negative terminal of a dc power supply. A high velocity jet flow of hot ionized gas melts the metal and then removes the molten material to form a kerf. Plasma arc spraying. The schematic arrangement of plasma arc machining is shown in fig.

The plasma arc cutting torch carries a tungsten electrode fitted in a small chamber. A plasma cutter will use this electrically conductive gas to transfer energy from a power supply to any conductive material resulting in a cleaner faster cutting process than with oxyfuel. The plasma arc cutting process is illustrated in fig. The basic arrangement for a plasma arc cutting torch similar to the plasma arc welding torch is shown in figure 10 71.

Materials and a pilot arc that makes cutting expanded metal possible. A plasma arc cutting machine cutting the internal sections of a metal part. For cutting slotting and profiling materials up to about 40 mm thickness using the keyholing mode of operation. Plasma arc machining is a metal removal process in which the metal is removed by focusing a high velocity jet of high temperature 11 000 c to 30 000 c ionized gas on the workpiece.

Manual plasma welding is operated over a range 0 1 to 100a from thinner foil to 3 4 mm thickness in stainless steel nickel and nickel alloys copper. This easy to use plasma cutter has the power to cut up to 3 8 in. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma typical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as well plasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle.
