FAQ
Q: Do I need two laser machines to engrave and cut separately?
A: No, the laser machines we provide 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 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 , etc.
 
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 65W.
 
Q: What are the applications for laser tubes with different powers? For example, what is the maximum thickness of PMMA that laser machine can cut?
A:
40W laser tube   5mm  PMMA
65W laser tube   10mm PMMA
80W laser tube   15mm PMMA
100W laser tube 20mm PMMA
130W laser tube   25mm PMMA
150W laser tube   30mm PMMA
Q: In general, how long is the service life of a laser tube?
A: Generally, a laser tube’s service life can reach 3500 hours to 9000 hours depending on the specific usage. For example, if it works 8 hours per day, the detailed data is as follows:
1. If you set the power at 20-30% of the total power, the service life is about 1-2 years.
2. If you set the power at 40-50% of the total power, the service life is about 1 year.
3. If you set the power at 70-80% of the total power, the service life is about 6-8 months.
Q: How can I tell the power of a laser tube has been exhausted?
A: The beam color of a new laser tube in operation is purple. When the power is gradually depleted, the color will become white.
 
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?
A: It is not harmful as long as the laser is not exposed directly to skin and eyes.
