Plasma torches abbreviate metal info using a high-voltage electrical arc in a stream of compressed air. Wait until the green light comes on the main panel.6. Set the nose of the plasma torch squarely at the beginning point of the cut on the aluminum sheet. Public amperage ratings are 25 amps for 1/4-inch-thick information and below. A 50- to 60-ampere machine will intersect up to a 1/2 inch thick. Machines in excess of 80 amperes Testament reduce 1-inch-thick aluminium sheets.
Instructions
1. Connect the compressed air source to the plasma cutting gadget. Locate the plasma torch air regulator as outlined in the manufacturer's directions. In popular, this Testament gamut between 80 and 90 pounds per square inch (PSI) of compressed air.
2. Attach the ground clamp to the aluminium leaf that is to be reduce. Cook a solid mechanical connexion with the clamp to the aluminium parcel.
3. Disinfected the surface of the aluminium stage with the rag. In some cases, where Exorbitant oils are on the aluminium surface, you may annex to clean it down with some acetone. Oils residing on the surface of the aluminium Testament interfere with the electrical connexion of the plasma torch.
4. Wear the catch safety gear on your item. The plasma stream Testament excrete a pleasant shower of sparks below the event aluminum. Wear dark eye protection as the plasma arc is extremely bright and will cause eye irritation.
5. Turn the plasma torch on. The machine will go through a self-check analysis. Plasma torches are rated by the vastness of amperage produced in the cutting stream. The higher the amperage adjudjing, the thicker the metal news that the torch can shorten. In usual, plasma torches can section thicker aluminium than steel.
If at all possible, this should be on the edge of the sheet aluminum.
7. Lift the nose of the plasma torch 1/16 of an inch from the aluminum sheet surface. Press the button on the plasma torch. The plasma stream will begin in less than a quarter second.
8. Drag the torch head across the aluminum sheet, toward you, as the stream is cutting the material. Keep the torch head moving at a consistent speed, not too fast and not too slow. It will take practice to match the thickness of the material with the torch head speed. The goal is to remove the solid aluminum as quickly as possible, but not so fast that you leave any stray material behind.
9. Release the button to shut off the torch head when you reach the end of the cut.
