What Causes a CO2 Laser Cutter to Lose Power?
The laser cutter, a versatile precision cutting tool, has become an indispensible element of modern businesses operating in the engineering and manufacturing industries. But as with all machines, laser cutters are prone to a range of problems that can require significant troubleshooting efforts. One of the most common problems experienced by operators of laser cutters is a decrease in the cutting power, which can be attributed to a range of different factors and issues. In this article, we’ll explore the most common causes of a loss of power in a CO2 laser cutter, and provide possible remedies and tips for resolving the issue.
1. Insufficient Air Flow
One of the most common reasons a CO2 laser cutter might lose its cutting power is related to air circulation within the unit. The laser cutter produces a beam of laser light, which when focused on a material causes it to be cut. In order for this process to work at optimum levels, the CO2 laser cutter must be properly ventilated to disperse the exhaust air and prevent any build up of heat, smoke or humidity.
If the ventilation within the system is inadequate, this can lead to a decrease in the cutting power of the laser, as the gases emitted during the cutting process will become too concentrated and subsequently reduce the quality of the cut. Poor ventilation can also result in too much heat being generated within the unit, which may cause components to overheat and put the system at risk of a fire.
To prevent a CO2 laser cutter from losing power due to insufficient air flow, ensure that the ventilation system is working properly and is pumping out at least 50 cubic feet of exhaust air per minute. If you are unsure of the ventilation system specifications of your particular model of laser cutter, consult the documentation that came with the machine or contact the manufacturer. Additionally, make sure that the laser cutter is positioned in an area that is free from obstruction, as air flow can be restricted if the unit is installed too close to walls or other equipment.
2. Faulty Electrical Connections or Components
Another possible reason for a CO2 laser cutter losing its cutting power could be due to faulty electrical connections or components. The laser cutter requires a certain amount of electrical power in order to operate, and any discrepancy here can lead to a loss of power output. This could be due to either faulty wiring or components within the system, such as capacitors, fans, transformers and amplifiers, or it could be due to inadequate power supply.
In order to identify and resolve the issue, it is necessary to get a professional to investigate the system’s electrical components and connections. For safety reasons, make sure that all electrical connections are securely tightened and properly insulated, and that all components are functioning correctly. Also, check that the unit is receiving the correct amount of electrical power – if it is not, contact a qualified electrician to have the power supply increased or redistributed.
3. Dirty Laser System Components
Another common cause of a CO2 laser cutter losing its cutting power is due to the build up of dirt and dust particles inside the system. As with any machine, accumulations of dust and dirt within the unit will affect its performance, as the internal components of the laser cutter need to stay clean in order to function correctly.
Therefore, it is important to regularly inspect and clean the system components of the laser cutter. Parts such as the mirrors, lenses and cooling system components should be routinely wiped down with an isopropyl alcohol solution, and other internal components should be kept free from dust to ensure proper air circulation. Additionally, you may need to replace the gas lens in the system, as it is prone to becoming clogged over time, reducing the power of the laser cutter and causing an increase in air consumption.
4. Incorrect Laser Cutter Settings
Finally, incorrect settings on the laser cutter control panel can cause a decrease in the cutting power of the CO2 laser. To ensure that the laser cutter has the correct settings, refer to the laser cutter operating manual and adjust the settings accordingly. If the settings seem to be correct but the laser still isn’t cutting properly, you may need to adjust the beam focus of the cutter, as incorrect beam focus can lead to poor quality cuts.
