Features: After the plates are adsorbed on the working face, the splicing of the plates is adjusted at a stable speed. If the working face is large, two splicing machines should be used to splice at the same time. If the vacuum cleaner cannot be operated at the same time, each device must be fine-tuned to prevent the suction cup and the working surface from moving laterally at the same time. When connecting small plates, make sure that they are on a horizontal surface and do not block each other. When connecting for the first time, press and hold for one minute, check it, and then turn it on after one minute. Repeat 2 times to repeat the pairing board.
