Laser cutting is accomplished by the application of high power density energy generated from focused laser. Under the control of computer, laser discharges through pulse and a output of high-frequency pulse laser forms light beam of particular frequency and pulse width. After conduction and reflection through optical path and focused by focusing lens group, the pulse laser beam becomes a subtle and high-energy density flare, located near to surface area to be processed and then it melts and gasifies the material in a moment. Every high-energy laser pulse can sputter a fine hole in a second. Under the control of computer, laser head and workpieces will move relatively and positioning according to the graph thus to get the desired shape.
It is quite dangerous if a laser cutting machine malfunctions in working process, so the operator must accept professional training before operate independently.

Below are 13 tips of safe operation details from specialists:
1. Comply with the general safety operation principles of cutting machine. Start laser in strict accordance with laser initialization routine.
2. Operators must have been trained to be familiar with structure and function of equipment and have enough knowledge of operating system.
3. Correctly wear and use labor protection articles; qualified protective glasses is a must when work near a laser beam.
4. Do not processing before making sure whether the material can be irradiated and heated by laser to avoid potential danger of produced smoke and vapors.
5. Do not leave the post when the equipment is running. Halt or switch off electrical power when leaving.
6. Make a fire extinguisher mounted in plain sight; turn off laser or optical shutter when not processing; place no combustibles like paper and cloth near the unprotected laser beam.
7. Halt immediately when any abnormality occur and carry out troubleshooting or report to personnel in charge as soon as possible.
8. Keep laser, lathe bed and the surrounding area clean and orderly; place workpieces, panels and wastes by regulation.
9. When use gas cylinder, avoid pressing the solder wire for fear of leakage accident. Use and transportation of gas cylinder must be abided by supervision regulation. Forbid prolonged sun exposure and source of heat on gas cylinder. Stand on the side of bottle neck when open valve.
10. Comply with high pressure safety procedures when maintain the equipment.
11. After startup, slowly start the machine in X and Y direction by hand to confirm there is no abnormalities.
12. Pilot run after input program on new workpieces and check the running condition.
13. Observe the running condition of machine when processing in order to avoid collision or running beyond the valid range.
