Fault 1: Start (power supply), (cooling), the switch is not powered
Treatment method: Water pressure switch does not work, remove the water supply pipe exhaust, and then plug in the water supply pipe
Fault 2: The laser of the main optical path is offset
Treatment method: Adjust the full and semi-reverse diaphragm of the main optical path, use image paper to view and adjust the spot
Fault 3: Laser welding machine welding penetration is not enough
Treatment method: Lack of laser energy can improve pulse width and current; The focus lens is not the right amount, and the amount of focus should be adjusted to get closer to the focus position.
Fault 4: During the working process, the buzzer buzzes, and soon the power is off, and the cooling water temperature exceeds the upper limit setting temperature
Treatment method: Check whether the external circulating water valve is open and whether the waterway is smooth.
Fault 5: Cooling water pollution or a long time did not replace the cooling water
Treatment method: Replace the cooling water and clean the filter UV glass tube and xenon lamp
Fault 6: Laser welding machine welding flame weakened
Treatment method: the shutter is not completely crowded out, and check the smooth shutter connector, so that the connector can be smoothly mechanical; The main optical path laser deviation, the main optical path full reflection and half reflection stop adjustment, like paper view, dot adjustment; Cooling water pollution or a long time do not replace the cooling water, replace the cooling water and clean the UV glass tube and xenon lamp can be dealt with; The laser is not output from the center of the copper nozzle under the aggregation head, and the 45° reflection stop is adjusted to make the laser output from the center of the nozzle. Aggregation lens or laser resonator film damaged or contaminated, should be replaced or cleaned in time.
Fault 7: Spinning (voltage conditioning) twisting, voltmeter has no indication
Treatment: The intelligent thyristor rectifier module is damaged, the regulator is faulty, the feedback button is closed, and the connection line is loose.
Fault 8: The resonator diaphragm of the laser is damaged or contaminated
Treatment method: Replace or clean the resonator reflection diaphragm.
