The first step: check whether the laser welding machine red light in the middle of the media diaphragm, or should adjust the location of the media diaphragm to make red light in the center of the media diaphragm.

Step 2: Rough the media diaphragm holder to reflect the red light back to the perforation.

The third step: open the badger Leng chu? The, the pulse width is adjusted to about 2ms, the repetition frequency is adjusted to 0Hz, and the foot switch is pressed to make the pulse xenon lamp flash. At this time, full black image paper is placed in front of the output mirror, and laser output can be observed. Adjust the two knobs of the diaphragm so that the output spot is round and uniform, and then gradually reduce the current to about 120A, and further carefully fine-tune the knob, as far as possible to hit the paper like the spot the most round and the strongest part Spot center. In the case of

Step 4: Check whether the laser coincides with the red light, will be fixed in the laser output mirror and try to stay away from the front end of the output mirror, issued a laser pulse to observe if the center of the spot on the paper coincides with the red center, such as Do not coincide, you can fine-tune the output mirror and the whole mirror, so that the spot and red light coincidence, and then fixed as the paper from the laser output mirror 800 ~ 1000mm place, once again check whether the spot coincides with the red light. If you can better coincide, the laser is adjusted to the best condition.

Step 5: lock each adjustment knob, once again check the paper as the spot is good, and with the red coaxial. Otherwise the laser welding machine should be re-adjusted.
