Plasma cutting is a cutting process which is used to cut through thin and thick metals. The plasma cutter can cut most types of metal. The reason why plasma cutting is so popular is because the intense heat allows the metal to be cut with precision and very quickly. The plasma torch is also easy to use so workman can be trained quickly. The following article is a list of the 7 most important tips when cutting metal with a plasma cutter. But first I want to give some information as to how the plasma cutting process works.

Plasma cutters can produce such precision cutting because it uses an electrically heated gas stream. The gas stream is heated to such high temperatures in the range of 25, 000°C, that it becomes ionised. This ionised gas is blown out through a nozzle at such high speeds, that an electrical arc is formed through the gas from the nozzle to the metal surface which is going to be cut. Some of the gas is transformed into plasma, this plasma is so hot that it melt the metal and the pressurised air blows the metal fragments away. The nozzle used to narrow the gas stream is made of alloy copper.

As stated before the plasma cutting torch is easy to use, yet there are regulations to be followed to get the best results when performing plasma cutting. Here are the 7 top tips:

1. Assemble the torch properly. It is important that the torch is assembled properly. Torches must be assembled in such a way that each part is fitted together properly and tightly. If not the gas will not flow properly through the torch and the torch will wear out quicker.

2. Check the gas and air flow. You need to do this every day. Gas pressure needs to be at the correct setting to ensure a constant arch. Set your air pressure to the factory recommended pressure, this will ensure that the parts will be cooled properly.

3. Clean work surface. Check that the metal surface where you are going to be cutting is clean and free from any pieces of metal.

4. Position torch the correct distance. Keeping the torch too far away from the metal will result in arc stretching. Arc stretching can damage the torch and should be avoided at all costs.

5. Do not let the torch drop. In order to have a torch which functions properly and delivers precision plasma cutting, care must be taken to nor drop the torch.

6. Clean your torch periodically. Torches must be cleaned to keep them functioning properly. Use cotton wool and hydrogen peroxide to clean the outside and inside threads as well as the nozzle.

7. Proper protection. Always use the proper protection when plasma cutting. You need welding goggles to protect your eyes as well as gloves. Workman protection is very important to prevent serious injury.

The level of quality you get from your plasma cutting is a result of a properly functioning plasma cutter, as well as some know how. Follow these 7 steps to ensure quality results.
