What is blue light from a plasma cutting arc?
Like any electric arc, a plasma cutting arc has a broad spectrum of electromagnetic radiation—from infrared light to UV (Ultra Violet) light. With plasma cutting, though, you’re exposed to intense “blue light,” which is the most visible light in the spectrum of light emitted by plasma arc cutting and the most dangerous.
