Plasma Arc Cutting Torch Diagram

So it acts as a cathode.

Plasma arc cutting torch diagram. The plasma arc cutting torch carries a tungsten electrode fitted in a small chamber. 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 schematic arrangement of plasma arc machining is shown in fig. Further the thickness of the internals at yankee rowe was at the limits of technological experience using plasma arc torch cutting.

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. 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. 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. 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.
