As a laser welding machine operator, to operate and maintain the laser welding machine must judge the common faults of the welding machine and solve it in time to reduce losses.

Fault 1: Start (power), (cooling), switch is not supplying power

Solution: The water pressure switch does not work. After the water supply pipe is turned off, plug it in again.

Fault 2: The light does not light on

Solution: Check the 220V of the pre-ignition board; whether the 3A fuse is good or bad, whether the xenon lamp is good or not.

Fault 3: The light is on, and the (auto) state does not light up

Solution: Check whether the 3A fuse on the large printed board is ok; whether the connector is loose and the working voltage is> 200V.

Fault 4: Turn the knob (voltage adjustment), the voltmeter has no indication

Solution: The smart thyristor rectifier module is damaged, the voltage regulator board is faulty, whether the feedback button is closed, and whether the connection line is loose.

Fault 5: During the work, the laser does not appear suddenly

Solution: Check the 3A fuse of the pre-ignition board, check for power failure; check whether the laser cavity is leaking.

Fault 6: During the work, the laser intensity becomes weak

Solution: Check the laser rod end surface for water seepage. If it stops, re-tighten the sealing O-ring and clean and maintain the rod end surface.

Maintenance. Check if the lens is fixed.

Fault 7: During the work, the buzzer beeps, and the power is cut off soon.

Solution: Check whether the external circulating water valve is open and the waterway is open.
