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: 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: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 , 60W or 80W. Q: In general, how long is the service life of a laser tube? A: Generally, a laser tube's service life can reach 5000 hours to 10000 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: 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.
