Fault 1: laser intensity decreased aluminum laser engraving machine, marking the solution is not clear enough: a laser resonator is change; fine-tune the resonant cavity lenses. The best spot of the output; two acousto-optic crystal sound and light power output offset or low energy; adjust the sound and light crystal position or increase the sound and light power supply current; 3 into the off-center laser galvanometer: adjust the laser; 4. If the current is adjusted to about 20A is still sensitive and strong enough: krypton lamp aging, replacement lamps. Fault 2: krypton lamp can not be triggered (see NTP power usage manual) Shenzhen closed water-cooled laser processing machines, laser power. Open the upper three cavity cover, remove to replace the lamp or crystal, the replacement into the laser engraving machine, mounted on the chamber cover. Open water-cooled machines, laser power, laser power supply current is set (15 ~ 20) A so. Place a small wood or black paper between the diaphragm and the first beam expander, you should see the spot formed by laser ablation. If there are no buttons laser the laser engraving machine, minor adjustments to the front of the diaphragm frame three knobs bottles laser engraving machine, until a spot appears. After three knobs laser commissioning out before adjustment should be repeated so that the diaphragm frame strongest spot, such as a laser is too strong, high brightness can not be observed, can reduce the supply current. Turn off the laser power. Special Note: krypton lamp replacement time.
