While using a plasma cutter for the first time may seem like a daunting process, the plasma cutting process is actually fairly straightforward, and you will be amazed at the high quality finish that they deliver.
Plasma cutting offers a highly efficient and cost effective way to cut steel and any other metal that conducts electricity. Using DC voltage to heat compressed air to a very high temperature, plasma cutting machines then ionise the atoms to create a pilot arc.
It is this small jet of plasma that pushes through and melts the metal, resulting in a precise cut edge and superior finish.
Using plasma cutting machines is simple and straightforward. All you need to do is follow the below steps.
You can choose to start from the edge of the piece or make a hole in the middle of the metal. Plasma cutting machines are capable of cutting through both thin and thick materials, and you can cut different sizes and shapes using templates.
In terms of ease of use, plasma cutting machines are hand held and have no heavy gas bottles that you need to transport around. They can be easily placed on the cutting table and carried from one work space to another.
Plus, if you have a large work order and need to cut outside of normal working hours, plasma cutters can be computer controlled, so less power is needed, and you can still expect a high quality, precise cut.
If you cut too slow, your plasma arc machine may start to splutter. However, if you cut too fast, you may experience a poor cut quality and a blowback of dross.
Therefore, you need to make sure that you are cutting at the right speed. To determine this, when you are cutting from the edge of the material, you need to ensure that the metal has been fully cut through and that the dross is coming out at a maximum of a 10-20 degree angle.
If the angle starts to increase and gets close to a 45-degree angle, you need to slow down your cutting speed. If you are struggling to get a precise and clean cut, you may need to increase your amperage.
