As China’s laser technology development, China’s original laser source has good performance and much competitive price now. So, the whole price of fiber laser cutting machines is more and more acceptable for the metalworking industry.

In order to meet the different metal cutting demands, 4000W fiber laser cutting machine also has different types to meet the metal sheet and metal tube cutting demands, Even the shaped tube or automobile spare parts both can cut by a 3D laser cutting machine.

4000w Fiber Laser Cutting Machine Is Out Of Power Cause Of Failure

1. Phase sequence error
2. The voltage is insufficient, the accessories are damaged, and the circuit is not fastened firmly

Solution
Solution 1: Check the phase sequence and change any two live wires to change the phase sequence
Solution 2: Check the main power output , the fire and the live wire voltage, the three live wires and the neutral voltage respectively, check the voltage of the phase sequence protection switch/three relays, the 220 behind the main AC contactor controls the pull-in voltage, and AC contact Whether the main line of the inverter is loose or whether the main AC contactor is burned out

The servo is out of power
Failure reason
1. Emergency stop press
2. The switch is not turned on, the wiring is not fastened firmly, the switch position of different models is different, please judge according to the model
3. Damaged accessories
4. Servo damage

Solution
Solution 1: Check whether the emergency stop switch is turned on (the old G machine also has an emergency stop switch on the left side of the beam)
Solution 2: FL.GMAHM.AM detects whether the electric lock, servo switch, and the relay that controls the servo AC contact pull-in are energized (the wire number is generally 5 and 24V-), whether the upper control line of the AC contact is energized, and whether it is wired If it is not connected properly, whether the relay is on. You can replace it with other 24V relays to determine if it is good or bad, and whether the AC contactor is damaged
Solution 3: H opens the servo circuit breaker and there is electricity, measure whether the circuit breaker has electricity and whether it is normal
Solution 4: Check whether the voltage of the electronic transformer is normal
Solution 5: Replace the servo

No power for laser water cooling

cause of issue
1. The external switch is damaged and the circuit is blocked
2. Internal problems of the water-cooled machine

Solution
Solution : Check the voltage at the terminal, the voltage of the circuit breaker, whether the main power supply of the machine, the voltage stabilizer or the field voltage is normal, whether the switch is damaged, replace the switch recovery circuit

Other common problems when using laser cutting machines are materials discharging from above and lack of precision on the surface area. The solution to this fiber laser cutting problem is simple. Like the other problems previously discussed, reduce the feed rate and increase the power if you encounter this issue. It’s also vital that you choose the right sheet metal for your job.

About 4000w fiber laser cutting machine and advantages
Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns, automatic typesetting, saving materials, smooth cuts, and low processing costs. It will be gradually improved or replaced. Traditional metal cutting process equipment. The mechanical part of the laser cutter head of the laser cutting machine has no contact with the workpiece, and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally does not require subsequent processing; the cutting heat affected zone is small, and the plate deformation is small. The slit is narrow. With the continuous development of laser technology, laser cutting machines have gradually replaced traditional cutting methods with their flexibility and flexibility.

Industry Applications
4000w fiber laser cutting machine as one classic model, widely used in life, such as processing of stainless steel kitchenware, storage cabinet and other cabinets, is closely related to people’s daily life.
Used for cutting a variety of metal plates, mainly used in stainless steel, carbon steel, galvanized sheet, electrolytic plate, brass, aluminum, various alloy plate, rare metal and other metal materials.
