DuriAuxiliary gas for Fiber Laser Cutting, did you get the right one?
The schematic diagram of laser cutting is shown in the following.
During the process, auxiliary gas is necessary to blow off the slag/dross in the kerf and cool down the cutting surface, also it protects lens and nozzle of laser. Basically there are 3 kinds of gas: Oxygen, Nitrogen and Air, any of them affects directly to the cutting performance, speed, thickness etc. So we really need to think better before action.
1.Oxygen
Oxygen is commonly used to cut thick carbon steel because the chemical reaction between iron element and oxygen helps the metal absorb heat and promotes it melt, which can greatly improve the cutting efficiency.
However, oxygen will cause a marked oxide film on the cut surface and it will have a quenching effect around, increases the hardness which impact on subsequent processing. It also turns kerf to black or dark yellow.
Generally, Oxygen assists carbon steel plates cut, low-pressure punching, and low-pressure cutting. Oxygen is generally vaporized from liquid oxygen which provided by the local supplier, so the quality of the gas source is clean and no need special treatment.
2. Nitrogen
Nitrogen will form around the molten metal as protective atmosphere while it’s assisting the cut, prevent oxidation of the material, avoid the formation of oxide film. However, the cutting speed is not as fast as oxygen, and the nitrogen consumption of the nitrogen is large which means the cost will be higher.
The non-oxidized surface has the characteristics of direct welding, strong corrosion resistance and the kerf turns white.
Generally, nitrogen is used to cut stainless steel, galvanized sheet, aluminum, aluminum alloy, brass and other materials, by low-pressure perforation and high-pressure cutting. When cutting with nitrogen, the change of the gas flow has a great impact on the cutting performance, in this case, make sure the gas flow is sufficient and constant. Nitrogen is usually vaporized from liquid nitrogen provided by supplier, so the quality should be clean.
3. Air
Air, as it’s the most economic medium because it’s much easier to obtain than oxygen and nitrogen, nobody can charge you for air!
Every 1 knows the air contains about 20% oxygen and about 78% nitrogen, so it can make up for both shortage and cutting speed is slower than oxygen but faster than nitrogen. Since the oxygen is involved, the kerf turns a little bit yellow. It’s the most economic option for you as long as you are okay with the color change.
Generally compressed air can be used for cutting sheet-metal parts, aluminum sheet, nonmetal and galvanized sheet etc., air assist can certainly reduce the oxide film and absolutely save your cost, therefore, air assist is more and more equipped in fiber laser cut industry.
Compressed air can be obtained easily with an air compressor, but not any air compressor can be equipped for Fiber Laser Cutter as the Air itself is not clean, especially after compressing, there are plenty of water, oil and particles and any of them sprayed on the lens, the transmission of laser beam will be seriously affected and focus scattered, resulting bad cutting effect such as bottom burrs or rough kerf, even obsolescence.
Situation could be much worse if it is high-power fiber laser, even a tiny particle or a little spray will very possibly burn your entire lens cone.
In order to make the most economic (Air assist) way workable, ensure cutting quality and avoid any damage for your fiber laser, the compressed air must be pure and constant, 100% meet ISO 8573-1-2571 standard.

How does variable speed drive technology improve air compressor efficiency?
Variable Speed Drive (VSD) technology improves air compressor efficiency by allowing the compressor to adjust its motor speed to match the compressed air demand. This technology offers several benefits that contribute to energy savings and enhanced overall system efficiency. Here’s how VSD technology improves air compressor efficiency:
1. Matching Air Demand:
Air compressors equipped with VSD technology can vary the motor speed to precisely match the required compressed air output. Traditional fixed-speed compressors operate at a constant speed regardless of the actual demand, leading to energy wastage during periods of lower air demand. VSD compressors, on the other hand, ramp up or down the motor speed to deliver the necessary amount of compressed air, ensuring optimal energy utilization.
2. Reduced Unloaded Running Time:
Fixed-speed compressors often run unloaded during periods of low demand, where they continue to consume energy without producing compressed air. VSD technology eliminates or significantly reduces this unloaded running time by adjusting the motor speed to closely follow the air demand. As a result, VSD compressors minimize energy wastage during idle periods, leading to improved efficiency.
3. Soft Starting:
Traditional fixed-speed compressors experience high inrush currents during startup, which can strain the electrical system and cause voltage dips. VSD compressors utilize soft starting capabilities, gradually ramping up the motor speed instead of instantly reaching full speed. This soft starting feature reduces mechanical and electrical stress, ensuring a smooth and controlled startup, and minimizing energy spikes.
4. Energy Savings at Partial Load:
In many applications, compressed air demand varies throughout the day or during different production cycles. VSD compressors excel in such scenarios by operating at lower speeds during periods of lower demand. Since power consumption is proportional to motor speed, running the compressor at reduced speeds significantly reduces energy consumption compared to fixed-speed compressors that operate at a constant speed regardless of the demand.
5. Elimination of On/Off Cycling:
Fixed-speed compressors often use on/off cycling to adjust the compressed air output. This cycling can result in frequent starts and stops, which consume more energy and cause mechanical wear. VSD compressors eliminate the need for on/off cycling by continuously adjusting the motor speed to meet the demand. By operating at a consistent speed within the required range, VSD compressors minimize energy losses associated with frequent cycling.
6. Enhanced System Control:
VSD compressors offer advanced control capabilities, allowing for precise monitoring and adjustment of the compressed air system. These systems can integrate with sensors and control algorithms to maintain optimal system pressure, minimize pressure fluctuations, and prevent excessive energy consumption. The ability to fine-tune the compressor’s output based on real-time demand contributes to improved overall system efficiency.
By utilizing variable speed drive technology, air compressors can achieve significant energy savings, reduce operational costs, and enhance their environmental sustainability by minimizing energy wastage and optimizing efficiency.
How do you maintain proper air quality in compressed air systems?
Maintaining proper air quality in compressed air systems is essential to ensure the reliability and performance of pneumatic equipment and the safety of downstream processes. Here are some key steps to maintain air quality:
1. Air Filtration:
Install appropriate air filters in the compressed air system to remove contaminants such as dust, dirt, oil, and water. Filters are typically placed at various points in the system, including the compressor intake, aftercoolers, and before point-of-use applications. Regularly inspect and replace filters to ensure their effectiveness.
2. Moisture Control:
Excessive moisture in compressed air can cause corrosion, equipment malfunction, and compromised product quality. Use moisture separators or dryers to remove moisture from the compressed air. Refrigerated dryers, desiccant dryers, or membrane dryers are commonly employed to achieve the desired level of dryness.
3. Oil Removal:
If the compressed air system utilizes oil-lubricated compressors, it is essential to incorporate proper oil removal mechanisms. This can include coalescing filters or adsorption filters to remove oil aerosols and vapors from the air. Oil-free compressors eliminate the need for oil removal.
4. Regular Maintenance:
Perform routine maintenance on the compressed air system, including inspections, cleaning, and servicing of equipment. This helps identify and address any potential issues that may affect air quality, such as leaks, clogged filters, or malfunctioning dryers.
5. Air Receiver Tank Maintenance:
Regularly drain and clean the air receiver tank to remove accumulated contaminants, including water and debris. Proper maintenance of the tank helps prevent contamination from being introduced into the compressed air system.
6. Air Quality Testing:
Periodically test the quality of the compressed air using appropriate instruments and methods. This can include measuring particle concentration, oil content, dew point, and microbial contamination. Air quality testing provides valuable information about the effectiveness of the filtration and drying processes and helps ensure compliance with industry standards.
7. Education and Training:
Educate personnel working with compressed air systems about the importance of air quality and the proper procedures for maintaining it. Provide training on the use and maintenance of filtration and drying equipment, as well as awareness of potential contaminants and their impact on downstream processes.
8. Documentation and Record-Keeping:
Maintain accurate records of maintenance activities, including filter replacements, drying system performance, and air quality test results. Documentation helps track the system’s performance over time and provides a reference for troubleshooting or compliance purposes.
By implementing these practices, compressed air systems can maintain proper air quality, minimize equipment damage, and ensure the integrity of processes that rely on compressed air.

5. Secure Connections: Use proper fittings, hoses, and couplings to ensure secure connections between the air compressor, air tools, and accessories. Inspect all connections before operation to avoid leaks or sudden hose disconnections, which can cause injuries or damage.
6. Inspect and Maintain: Regularly inspect the air compressor for any signs of damage, wear, or leaks. Ensure that all components, including hoses, fittings, and safety devices, are in good working condition. Follow the manufacturer’s recommended maintenance schedule to keep the compressor in optimal shape.
7. Electrical Safety: If the air compressor is electric-powered, take appropriate electrical safety precautions. Use grounded outlets and avoid using extension cords unless approved for the compressor’s power requirements. Protect electrical connections from moisture and avoid operating the compressor in wet or damp environments.
8. Safe Start-Up and Shut-Down: Properly start and shut down the air compressor following the manufacturer’s instructions. Ensure that all air valves are closed before starting the compressor and release all pressure before performing maintenance or repairs.
9. Training and Competence: Ensure that operators are adequately trained and competent in using the air compressor and associated tools. Provide training on safe operating procedures, hazard identification, and emergency response protocols.
10. Emergency Preparedness: Have a clear understanding of emergency procedures and how to respond to potential accidents or malfunctions. Know the location of emergency shut-off valves, fire extinguishers, and first aid kits.
By adhering to these safety considerations and implementing proper safety practices, the risk of accidents and injuries associated with operating an air compressor can be significantly reduced. Prioritizing safety promotes a secure and productive working environment.
