plasma cutting

one of our family friends eric recently told me he is getting a plasma cutting machine for his business. i didn't have any clue on what the machine really is for. he explained to me that plasma cutting machines are used to cut steel and other metals using a plasma torch. the plasma is sufficiently hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut. Plasma can also be used for plasma arc welding and other things. i was still clueless and then he told me that in short getting the plasma cutting systems can increase quality, productivity, and his profits. see, i don't really need techincal explanations to understand.
