PCB engraving machine I believe we all know the temperature affects power laser tube, but besides temperature and other factors also affect the power of laser tube, you know what?
1, gas
To the beginning of a PCB laser engraving machine understanding inside a tube of pure carbon dioxide gas is very low, the output power. Then gradually to participate in a number of auxiliary gas, such as helium, makes the power greatly increased laser tube. Helium is present on the laser tube dedicated auxiliary gas largest, is mainly due to helium has a thermal conductivity good rate. After laser tube in helium, can be very good control of temperature in the stop operation, has a very good role in promoting the power of laser tube.
2, temperature
PCB engraving machine understanding to the laser tube high temperature will form the internal carbon dioxide gas synthesis, thereby reducing the concentration of carbon dioxide gas laser tube, so that the laser tube power landing. If no homework when the temperature effective control, power laser tube will be landing soon, until no, serious condition even breakdown of glass shell and tube, forming a loss.
3, the current
A laser tube, current is also a important factor. PCB engraving machine understanding to the power of laser tube and gradually increase as the current increase, but when the power of the laser tube reaches the maximum value of the time, continue to increase the current, but will make the power fall. This is because when reaching the maximum power, continue to increase the current makes the laser tube temperature beyond the range of the laser tube can accept laser tube power began to fall.
