Metal laser cutting machine glass tube is the key to the light

Metal laser cutting machine of the glass tube of the light control mainly has the laser tube, laser power supply, water circulation system and the signal light, the light signal and PWM give out light signals, including interface card water protection signal, door switch signal, etc. Metal laser cutting machine laser tube is not out of the light from the laser tube, laser power supply system of water circulation and the optical signal several aspects, the general first view was made in the laser power supply is normal electricity directly, the laser tube pipe outside if there is a difference, the water cycle system is normal, if not often replace or adjust them accordingly. In the above several aspects to normal circumstances should consider the light signal problems, general first sub signal ( Short of by laser 5 v power supply current and short AIN water conservation P &gnd with no lock switch control L &gnd) Methods to test the laser tube and laser power supply. If this method of light ok then laser diode laser power supply trouble-free, is the water protection switch, relay, switch, boards PWM signal to signal problems, such as, in turn, can be ruled out. If this method is not the laser tube and laser power supply problems alone, in the case of bad judgment with replacement method can be solved.
