Fiber Lasers Machinery Locations
Plasma's workings can seem complicated. This is why I will try to explain plasma as clearly and quickly as possible. Plasma cutters heat up gas until it is hot enough to melt metal. When the metal is sufficiently heated to melt it, it is then blown off with gas to make the cut. It's complicated science but it's not what I will be focusing on. (Or you can do your own research if necessary).
Fiber lasers are very popular in engraving applications. They have wavelengths ranging from 780nm up to 2200nm.
