What if the laser tube of the laser engraving machine is not bright?

For the problem that the laser tube of the laser engraving machine does not light up, start with the following general solutions and solve and analyze the specific reasons together.

① If the power supply line is broken, the voltmeter display is common. Poor contact with the foot switch or manual switch.

Check: Measure using a multimeter.

Treatment: Repair or replacement.

② There is no indication on the voltmeter The common fuse is broken or the circuit is open.

Check: Measure using a multimeter.

Action: Replace the fuse or connect the circuit.

③The power indicator does not light, the common fuse is blown, the input line connection is defective, the indicator circuit is defective, or the indicator is broken.

Check: Check the fuse, check the power line, check the indicator circuit.

Action: Replace the fuse, repair the wire and replace the indicator light.

④Continuous combustion of the fuse is often seen in short circuits inside the machine or serious dirt inside the machine.

Check: Check the wires step by step, mainly because the high voltage parts are shorted.

Treatment: Repair the short circuit and remove the dirt.

⑤There is a discharge sound and arc light in the machine. It is common for the cabin to be high in dust, water, air humidity and corrosive gases.

Check: Observe the discharge point in a dark place.

Treatment: Remove dust and water, and change the working environment.

⑥Laser output is unstable. Found on machines with poor contact, the machine has slight intermittent short circuits.

Check: Checks the line level for each level.

Treatment: Replace the wire, reweld the ends of the wire and clean.
