The plasma cutting process started around the 1950s. It uses a plasma torch in the cutting process. The plasma torch creates a hot jet of plasma that can even melt through the hardest materials. When the plasma torch is activated, it projects a mixture of gases, such as nitrogen and hydrogen, through the nozzle, which consequently creates plasma.
Most people believe that plasma uses fire or flame, but, on the contrary, plasma cutting doesn’t. Instead, it uses conductive ionized gas, also known as plasma. It’s an understatement to say plasma is hot. Typically plasma reaches about 40,000 degrees Fahrenheit.
When performing plasma cutting, workers need to wear proper personal protective equipment (PPE) to protect their face from arc eye (also referred to as photokeratitis or ultraviolet keratitis), which occurs as a result of eyes exposure to high levels of radiation.
