And the safety lock of laser pointer equips with two keys. 
The maximum speed can reach 750mmin. Laser welding system, the role of the computer software is the trajectory and speed of the laser head, the process parameters of laser power and general digital control to improve the processing speed and accuracy, and the purpose to improve processing quality, traditional laser processing software control is no different, but because of the special role of absorbers in the laser welding of plastics, plastic laser welding control system and processing system has its own characteristics. The British TWI Institute of ClearWeld plastic welding process, design and development of software that calculate the forecast absorbent dosage and According to the thickness of different materials, colors, absorption ratio, combined with the laser power, light wave transmittance parameters. The hand strap of laser pointer  can avoid the green laser pointer falling down or sliding away accidentally.
Software to calculate the amount of absorbent and add before welding, then add the forecast amount of absorbent. Input data to the software include: plastic material properties: type, thickness, color; welding data: welding the complexity of the area shape, width, welding speed; Lasers: power, infrared light transmittance. Calculation and filtering the output of software gives the results include: absorbent type, dosage, and requirements to add a list of ways, welding laser light waves in the energy loss in the upper material. Software calculation results very close to the actual welding measurement results, Figure 6 is generated after welding heat affected zone (HAZ) size of the calculated value and the actual measurement value comparison, the plastic material of PMMA. The laser color of laser pointer is more suitable to the practical use of the customer.The color of the laser beam light of laser pointer should also be stated clearly
Open the machine check, you can see the sheet-fed successfully by feeding parts of the two jam roll, but paper is no longer move forward under the tray card to multiple sheets of paper in the feed components before the jam roll at and stops there. Reasons, there is a gap between the jam roll and the feed roller of the feed components, paper not the friction between the jam roll and the feed roller, cause the media to stop this phenomenon is due to the long a paper jam occurs, resulting in feeding parts to jam roller shelves spring deformation and lose their elasticity, resulting in a jam roll jam is not enough friction between the paper feed roller, paper, although able to pass the jam roll but can not move on.
