Do you know how to troubleshoot the flow alarm in TEYU S&A handheld laser welding chiller? Our engineers specially made a chiller troubleshooting video To help you better solve this chiller error. Let's take a look now~When the flow alarm activates, switch the machine to self-circulation mode, fill the water to the maximum level, disconnect external water pipes, and temporarily connect inlet and outlet ports with pipes. If the alarm persists, the problem might be with external water circuits. After ensuring self-circulation, potential internal water leaks should be examined. Further steps involve checking the water pump for abnormal shaking, noise, or lack of water movement, with instructions on testing pump voltage using a multimeter. If issues persist, troubleshoot the flow switch or sensor, as well as circuit and temperature controller assessments. If you still can't solve the chiller failure, kindly send an email to service@teyuchiller.com to consult TEYU S&A service team.

If your TEYU S&A fiber laser chiller CWFL-2000 triggers an ultrahigh room temperature alarm (E1), follow these steps to resolve the issue. Press the "▶" button on the temperature controller and check the ambient temperature ("t1"). If it exceeds 40℃, consider changing the water chiller's working environment to the optimal 20-30℃. For normal ambient temperature, ensure proper laser chiller placement with good ventilation. Inspect and clean the dust filter and condenser, using an air gun or water if needed. Maintain air pressure below 3.5 Pa while cleaning the condenser and keep a safe distance from the aluminum fins. After cleaning, check the ambient temp sensor for abnormalities. Perform constant temperature testing by placing the sensor in water at around 30℃ and compare the measured temperature with the actual value. If there's an error, it indicates a faulty sensor. If the alarm persists, contact our customer service for assistance.

Robotic laser welding machines offer higher precision and efficiency, greatly improving production efficiency and reducing human errors. These machines consist of a laser generator, fiber optic transmission system, beam control system, and robot system. The working principle involves heating the welding material through a laser beam, melting it, and connecting it. The highly concentrated energy of the laser beam enables fast heating and cooling of the weld, resulting in high-quality welding. The beam control system of the robotic laser welding machine allows for precise adjustment of the laser beam's position, shape, and power to achieve perfect control during the welding process. TEYU S&A fiber laser chiller ensures the reliable temp control of the laser welding equipment, ensuring its stable and continuous operation.

We guide you through the process of reinforcing the water tank in our TEYU S&A 6kW fiber laser chiller CWFL-6000. With clear instructions and expert tips, you'll learn how to ensure the stability of your water tank without obstructing essential pipes and wiring. Don't miss this valuable guide to enhance the performance and longevity of your industrial water chillers. Let’s click the video to watch~Specific Steps: First, remove the dust filters on both sides. Use a 5mm hex key to remove the 4 screws securing the upper sheet metal. Take off the upper sheet metal. The mounting bracket should be installed roughly in the middle of the water tank, ensuring it doesn’t obstruct the water pipes and wiring. Place the two mounting brackets on the inner side of the water tank, paying attention to the orientation. Secure the brackets manually with screws and then tighten them with a wrench. This will securely fix the water tank in place. Finally, reassemble the upper sheet metal and the dust...

The concept of “wastage ” has always been a vexing issue in traditional manufacturing, affecting product costs and carbon reduction efforts. Daily use, normal wear, and tear, oxidation from air exposure, and acid corrosion from rainwater can easily result in a contaminant layer on valuable production equipment and finished surfaces, affecting precision and ultimately impacting their normal usage and lifespan. Laser cleaning, as a new technology replacing traditional cleaning methods, primarily utilizes laser ablation to heat pollutants with laser energy, causing them to instantly evaporate or sublime. As a green cleaning method, it possesses advantages unmatched by traditional approaches. With 21 years of R&D and production of laser chillers, TEYU S&A can provide professional and reliable temperature control for laser cleaning machines. TEYU chiller products are designed in strict accordance with environmental protection. With a large cooling capacity, precise temperature co...

Do you know how to judge the quality of laser processing? Consider the following: airflow and feed rate influence surface patterns, with deeper patterns indicating roughness and shallower patterns indicating smoothness. Lower roughness signifies higher cutting quality, impacting both appearance and friction. Factors like thicker metal sheets, inadequate air pressure, and mismatched feed rates can cause burrs and slag during cooling. These are vital indicators of cutting quality. For metal thicknesses exceeding 10 millimeters, the perpendicularity of the cutting edge becomes crucial for improved quality. The kerf width reflects processing accuracy, determining the minimum contour diameter. Laser cutting offers the advantage of precise contouring and smaller holes over plasma cutting. Besides, a reliable laser chiller also plays an important role. With dual temperature control to cool the fiber laser and the optics simultaneously, stable cooling and high efficiency, TEYU water chiller...

In this video, TEYU S&A guides you in diagnosing the ultrahigh water temperature alarm on the laser chiller CWFL-2000. First, check if the fan is running and blowing hot air when the chiller is in normal cooling mode. If not, it could be due to a lack of voltage or a stuck fan. Next, investigate the cooling system if the fan blows out cold air by removing the side panel. Check for abnormal vibration in the compressor, indicating failure or a blockage. Test the dryer filter and capillary for warmth, as cold temperatures may indicate a blockage or refrigerant leakage. Feel the temperature of the copper pipe at the evaporator inlet, which should be icy cold; if warm, inspect the solenoid valve. Observe temperature changes after removing the solenoid valve: a cold copper pipe indicates a faulty temp controller, while no change suggests a faulty solenoid valve core. Frost on the copper pipe indicates a blockage, while oily leaks suggest refrigerant leakage. Seek a professional welder...
