Types of Plasma Cutters in addition to Gases
1. Mode of Operation (How it works)
a. Influenza A virus subtype H5N1 “plasma arc” is a electrical current of electricity beingness carried past times an ionized gas is stead of a conventional conductor. Plasma is also considered the quaternary solid set down of matter, the offset iii beingness solids, liquids, in addition to gases.
b. Using the plasma arc in addition to a high-pressure gas to direct the arc through a constricted opening, it becomes a really useful cutting tool. The plasma arc melts the metallic in addition to the gas pressure level blows the melted metallic away. Using an inert gas for pressure level volition preclude the cutting areas from oxidizing. For well-nigh ferrous metals, compressed air industrial plant only fine, nonferrous metals the inert gas is essential to preclude oxidation.
2. Types of Plasma Cutters
a. Transferred – In the transferred scheme the arc is completed past times making contact with the workpiece.
b. Non-transferred – In the non-transferred scheme the arc is completed past times making contact with nozzle, it tin create an arc without touching the grounded workpiece in addition to tin live really dangerous.
Types of Gases
a. Primary Plasma Gas – used to create the plasma arc
1) Nitrogen – Is a mixture of 30% hydrogen in addition to 70% argon mixture.
2) Argon
3) Hydrogen
4) Compressed Air (The well-nigh mutual type used inward high schoolhouse silver Mech shops.)
b. Secondary Shielding Gas – used to protect the cutting metals from oxidation.
1) CO2
2) Compressed Air (The well-nigh mutual type used inward high schoolhouse silver Mech shops.)
Safe Use of a Plasma Cutter
1. Safety is a really piece using a plasma cutter, it tin cutting through a person’s clothes, skin, in addition to bones only every bit easily every bit it tin cutting through stainless steel. Influenza A virus subtype H5N1 non-transfer type of plasma cutter does non involve to live grounded to create a plasma arc. Extra security precautions involve to live taken if yous are using this type of plasma cutter. Be certain to read the manufacture security precautions before using their plasma cutter.
Operating a Plasma Cutter
1. Set the amperage in addition to gas pressure level to the manufacture’s specification. The metallic thickness, type, in addition to type of gas beingness used should live considered.
2. When making similar a shot cuts, job a similar a shot border guide. Steady yous elbow or forearm on the worktable or workpiece piece cutting.
3. Use at to the lowest degree a #9 guess or higher welding helmet piece cutting with a plasma cutter. The plasma arc is only every bit brilliant every bit an arc using for TIG, MIG, or Arc welding.
4. To start your cut, motility the plasma torch into position. Cover with your welding helmet in addition to press downwards on the start button. The arc volition appear when yous press downwards on the button, motility the arc along the marked expanse where the cutting is to live made. Keep a working distance at to the lowest degree 1/8" in addition to upwardly to3/16", the distance betwixt the workpiece in addition to the nozzle.
5. After the cutting is made, inspect the cutting for slag, stone oil areas, in addition to uncut areas. Adjust go speed in addition to amperage accordingly.
Activity:
1. Demonstrate the proper laid in addition to shutdown procedures, according to the manufactures’ recommendations.
2. Use the owner’s manual, conduct hold apart the torch in addition to present students the dissimilar parts of a plasma torch.
