This is the use of electronic ionized gas (or plasma) to cut through electrically conductive material. This technique is used to cut through metals like: If speed and precision are important to your work, a plasma cutter may be a good addition to your tool and equipment collection. These products are very affordable, which makes them a good investment for professionals. You will often find a combination unit you can use to weld. This involves creating an electric beam of heated electronically-ionized gas to complete an electrical circuit through the material you are cutting. A ground clamp completes the circuit back to the unit. The plasma can be made depending on what material you are cutting and you can get best plasma cutter under $500 by reading the article. It is created by compressing gases like oxygen, inert and air, and blowing it through an concentrated nozzle.
The plasma cutter blows concentrated gasses onto the metal surface. An electrical arc forms within this gas, which connects an electrode close to the gas and the metal you are cutting. Plasma forms when the electric arc ionizes gas. This causes it to melt. This is because you blow the matter at high velocity towards your work object. It blows away the molten steel and divides it. This allows you to make neat, angular or curved cuts. What consumables are necessary for a successful cut? The typical plasma cutter system uses five consumables: the shield and retaining cap, swirls rings, nozzle and electrode. This shield protects the other consumables from molten metal or sparks. A drag shield is a good option if you are not familiar with these machines.
The amperage rating will determine the duration of the duty cycle. The plasma cutter’s ability under certain loads for a specified time is called the duty cycle. You want to ensure you purchase a high-performing model. A solid unit can make a 1/4″ cut. This is the maximum width you can cut. Pushing for more can compromise precision and neatness. A lower duty cycle means better performance for a shorter time. Your project will be more difficult and performance may drop after this time. A duty cycle of between 50% and 60% is sufficient for heavy-duty projects.
