What is the most powerful laser you can legally own
Unlike CO2 lasers, fiber lasers consume much less energy and operate at a shorter wavelength ranging between 780 nm and 2200 nm, giving a much higher absorption rate.
Plasma working can be complicated. I'll explain the basics as quickly as possible. Plasma cutters heat up gases so that they can melt metal. After the metal melts, it's blown out with gas. The science behind this is complex, but I'll spare you the details. You can either do some research yourself or ask me.
