Laser tube voltmeter include instruction light not working light joint heat

Common in the light of joint mobilization and laser tube installed. Inspection method: optical correction. Remedy: replace or adjust the light guide, calibration light path. II laser power is reduced

Common in laser tube aging. Check: voltage with a multimeter check the voltage regulator with a pressure gauge to check the laser tube operating voltage. Treatment: replace aging laser tube and replace the damaged components.

Laser tube is not lit ① voltage meter indicating common in power supply lines open. And foot pedal or manual switch connection is bad. Check: measured with a multimeter. Address: repair or replacement. ② voltmeter without indication

A common fuse or circuit open circuit. Check with a multimeter measurement. Treatment: replace the fuse, or close the circuit. ③ power led not lit

Common fused, into the line of poor contact, poor light lines or bad led. Check: check for blown fuses, check the power wire and check the led circuit. Treatment: replace the fuse and repair the wires and replace the led. ④ continuous burning fuse is common in short circuit inside the machine, and inside there are serious dirt. Check: step by step check line for HV circuit. Address: fix short circuit, remove dirt. ⑤ machine discharge or arc common dust inside the machine, standing water or excessive humidity and corrosive gases. Check: in the dark discharge points. Treatment: removal of dust, water, and replace the work environment. ⑥ Laser instability

In CO2 laser marking machine has poor contact points, a slight intermittent fault in the machine. Check: check line step by step. Treatment: replace wire, welding head again, cleaned.
