Fiber laser cutting machines have many good performance features, but the cutting machine equipment needs to be properly controlled and used to perform its functions stably. If the control is misused, not only will it not be able to perform well, but it will also be damaged.
So, with so many brands and models of fiber laser cutting machines on the market, how do you choose the equipment that best suits you? This article will provide a detailed buying guide to help you easily choose the right laser-cutting machine.
1) The basic principle of laser cutting: Laser cutting irradiates the surface of the material with a high-energy-density laser beam, causing the material to quickly melt, vaporize, or reach the ignition point. At the same time, the melted or burning material is blown away with the help of auxiliary gas, thereby realizing the material of cutting.
2) Characteristics of fiber laser cutting machine: using optical fiber transmission, high precision, fast speed, smooth cutting surface, small heat-affected area, environmental protection, etc.
1) Cutting thickness: Choose the appropriate cutting thickness according to production needs. Generally speaking, the cutting thickness of the laser cutting machine should be greater than the thickness of the cutting material required for production.
2) Power and speed: Power determines the depth and speed of cutting, and cutting speed directly affects production efficiency. Generally speaking, the higher the power, the faster the cutting speed.
3) Machine accuracy and stability: Accuracy and stability are important indicators for measuring laser cutting machines, directly affecting the final cutting effect and product quality.
4) Auxiliary systems: such as dust removal, cooling systems, etc. These systems can protect equipment and improve cutting quality.
5) After-sales service: Choose a brand with good after-sales service to ensure that equipment failures can be resolved promptly.
The laser power of the fiber laser cutting machine has a considerable impact on the cutting speed, slit width, cutting thickness, and cutting quality. The amount of power required depends on the characteristics of the material and the cutting mechanism. For example, materials with good thermal conductivity, high melting point, and high surface reflectivity require larger laser power. Generally, when other conditions are certain, there is a laser power that achieves the best cutting quality in laser cutting processing. If the power is further reduced or increased, slag hanging or over-burning will occur, decreasing processing quality.
In addition, as the discharge voltage of the fiber laser cutting machine increases, the intensity of the laser will increase due to the increase in the input peak power, so the diameter of the spot increases and the width of the slit increases accordingly; as the pulse width increases, the laser The average power will increase, and the width of the laser slit will increase; usually, as the pulse frequency increases, the slit will also become wider. When the frequency exceeds a certain value, the slit width will tend to decrease.
Poor cutting quality: It may be caused by insufficient laser power, too slow cutting speed, too large cutting depth, etc. The solution is to adjust the laser power, cutting speed, and depth, or replace with higher quality cutting materials.
Cutting size exceeds limit: Some laser cutting machines may have maximum cutting size restrictions. The solution is to choose a cutting machine of the right size or to pre-treat the material before cutting, such as cutting it to the right size.
Knife jamming occurs during cutting: it may be caused by blade wear, incorrect blade position, etc. The solution is to replace the blade or adjust the blade position.
The device won’t start or stop working: It could be a power issue, a device failure, etc. The solution is to check the power supply and contact after-sales service for maintenance.
Keep the environment around the equipment clean: avoid dust, debris, etc. from entering the equipment and affecting its normal operation.
Please check the use of wearing parts such as blades and optical fibers, and replace or repair them in time.
Avoid touching hot parts while the equipment is running to avoid burns.
Ensure that operators have appropriate operating skills and knowledge to avoid equipment damage or production safety accidents caused by improper operation.
Follow the safety guidelines in the equipment instruction manual to ensure safe operation of the equipment.
Fiber laser cutting machines have become a powerful tool in the manufacturing industry due to their high efficiency, accuracy and environmental protection. When purchasing, we need to understand the principles and characteristics of the equipment and pay attention to key factors such as cutting thickness, power and speed, accuracy and stability, auxiliary systems, and after-sales service.

Hopefully, this article will provide you with a comprehensive buying guide to help you make an informed choice when purchasing a fiber laser cutting machine.
Handheld laser welding machines have become increasingly popular across industries such as metal fabrication, machinery manufacturing, and automotive repair due to their efficiency, precision, and portability. With so many options available on the market, selecting the right machine can be overwhelming. This guide will walk you through how to choose best laser welder in , helping you make a smart and confident investment.
Here are five steps to follow when choosing a laser welding machine , ensuring you find the right fit for your application, budget, and performance requirements.
1. Identify Your Requirements: The First Step to Choosing the Right Laser Welder
Understanding your specific needs is crucial to selecting the right equipment. Factors such as the type of material to be welded, its thickness, and precision requirements all significantly influence the configuration of the machine. That’s why it’s not possible to quote a price for a laser welding machine directly. Only after fully understanding your specific welding needs can we recommend a suitable configuration and provide an accurate quote.
Common metal materials such as stainless steel and carbon steel typically require W~W;
High-reflective materials like aluminum are best handled with power above W.
2. Understand Welder Performance
When selecting a laser welding machine, welding performance is one of the key factors to consider. The main performance aspects include:
Wanxuan supply professional and honest service.
3. Compare Price and Brand
Generally, well-known brands offer better assurance in terms of product quality, craftsmanship, and operational stability, but they often come with higher price tags. Therefore, it’s advisable to balance your choice based on your budget and actual application needs.
Proper training is essential to ensure effective operation and maintenance of the laser welding machine. Reliable technical support should also be available in case of operational issues. When comparing brands, consider their training programs and service capabilities. Many manufacturers are growing rapidly, but reputable brands typically use higher-quality original components and provide better after-sales service.
High-quality after-sales service is critical to ensure long-term stability and minimize downtime due to equipment failures. Key aspects to evaluate include availability of timely technical support, repair response times, and warranty periods.
If conditions allow, it is strongly recommended to visit the manufacturer or local distributor for an in-person evaluation. Observing the machine in real-world applications and performing a hands-on trial can help you assess ease of operation, welding smoothness, and overall suitability for your use case.
