Q: Do I need two laser machines to engrave and cut separately?
 A: No, the laser machines are capable of both engraving and cutting. One machine alone can fulfill the two purposes.
 Q: Do the laser machines need to be connected to a laptop or desktop computer to work?
 A: Yes, either is ok. It supports Windows 10, Windows 2000, Windows XP, Win 7, and other operating systems
 Q: What kind of graphic format does it support?
 A: JPG, PNG, BMP, PLT, DST, DXF, CDR, AI, DSB, GIF, MNG, TIF, TGA, PCX, JP2, JPC, PGX, RAS, PNM, SKA, RAW.
 Q: How to distinguish laser tubes with different powers and applications?
 A: 1. Laser tube length (relatively speaking, the longer, the bigger)
     2. Laser tube diameter (relatively speaking, the thicker, the bigger)
     3. The bigger a laser tube power is, the deeper the machine can cut, but its light spot is bigger. So, it is better to use a  machine with a low-power laser tube to engrave, such as 40W, 50W or 60W.
 Q: Is it better to increase blow to improve laser processing performance?
 A: For some thick materials, it works. But, when carving some other materials, you need to blow less.
 Q: How long will it take to learn to operate a laser machine?
 A: If you are able to use some basic graphic design software, it will only take a few hours to master the operation. You just    need to do some simple tests on different processing materials to know how to set the correct speed and laser power.
 Q: Is a laser machine in operation harmful to our bodies?
