The laser tube on the voltmeter indicates that ① the light output is abnormal, and the light guide joint is heating up
Commonly seen in loose light guide joints and misaligned laser tubes. Inspection method: Same light correction. Troubleshooting measures: Replace or adjust the light guide section and correct the optical path. ② Laser power decrease
Commonly seen in aging of laser tubes. Inspection: Use a multimeter voltage range to check the voltage regulator, and use a high voltage meter to check the working voltage of the laser tube. Handling: Replace aged laser tubes and replace damaged components.
The laser tube does not light up. ① The voltage meter indicates that there is an open circuit in the power supply line. Poor contact with foot switch or manual switch. Check: Measure with a multimeter. Handling: Repair or replace. ② No indication on the voltmeter
A common cause is a broken fuse or an open circuit in the circuit. Check and measure with a multimeter. Handling: Replace the fuse or connect the circuit. ③ The power indicator light is not on
Common issues include broken fuses, poor contact of incoming wires, poor wiring of indicator lights, or faulty indicator lights. Inspection: Check the fuse, check the power input line, and check the indicator light circuit. Handling: Replace fuses, repair wires, and replace indicator lights. ④ Continuous fuse burning is common in cases of short circuits and severe dirt inside the machine. Inspection: Check the wires step by step, mostly due to short circuits in the high-voltage section. Solution: Repair short circuit and remove dirt. ⑤ There is discharge sound or arc light inside the machine. It is common to see dust, water accumulation, high air humidity, and corrosive gases inside the machine. Inspection: Observe the discharge point in the dark. Treatment: Remove dust, accumulated water, and other objects, and change the working environment. ⑥ Laser output instability
There are poor contact points and slight intermittent short circuits inside the CO2 laser marking machine. Inspection: Check the line step by step. Handling: Replace the wires, re weld the wire ends, and clean them.
