DXTECH Portable Hand Held Laser Cleaning Machine Care and Maintenance Instructions

Portable handheld laser cleaners have become a revolutionary solution in modern industrial cleaning. Their ability to efficiently and accurately remove rust, paint, oil and coatings from a wide range of surfaces has made them a staple in many industries. Laser cleaners offer a non-contact cleaning method that not only ensures the integrity of the substrate being cleaned, but also the speed and quality of the cleaning. However, proper maintenance is critical to ensure that these machines continue to perform at their best. This article will take an in-depth look at the maintenance requirements for portable handheld laser cleaners, as well as other important aspects such as product construction and selection criteria.

Laser cleaning vs. conventional chemical cleaning

From the point of view of cleaning efficiency, in the automotive parts cleaning scenario, the traditional manual chemical cleaning method, cleaning a medium-sized engine block, it takes about 3 – 4 hours, and due to the differences in manual operation, the cleaning effect is uneven. The use of portable handheld laser cleaner, only 30 – 40 minutes, can achieve or even exceed the traditional cleaning method of cleaning results, efficiency increased by 5 – 7 times.

In terms of protecting the cleaned substrate, traditional chemical cleaning may cause a certain degree of corrosion on the substrate. According to relevant research data, after 5 times of traditional chemical cleaning, the thickness of the metal substrate will be reduced by 0.05 – 0.1 mm on average. The portable handheld laser cleaner adopts the principle of non-contact cleaning, avoiding direct physical contact with the substrate, fundamentally eliminating the mechanical damage to the substrate, to maintain the original structure and performance of the substrate intact.

At the environmental level, the traditional chemical cleaning of every 100 square meters of metal surface treatment, will produce about 80 – 100 liters of chemical wastewater, which contains a large number of heavy metal ions and organic pollutants, treatment costs are high. If discharged directly without effective treatment, it will cause serious pollution to the soil, water and so on. In contrast, portable handheld laser cleaner in the cleaning process without the use of chemicals, does not produce any chemical wastewater, from the source to reduce the pollution of the environment, the real realization of green cleaning.

Product Structure

DXTECH typical portable handheld laser cleaning machine, consists of several key components. The oscillating mirror motor module plays a vital role in controlling the direction of the laser beam, allowing for precise cleaning in different areas. The collimation modules are responsible for aligning the laser beam, ensuring it travels in a parallel and focused manner. The QBH and QBS joints are used for connecting different parts of the optical system, enabling seamless transmission of the laser energy.

The spotlight module focuses the laser beam onto the target surface, increasing its intensity for effective cleaning. The dual protective lens module safeguards the internal optical components from dust, debris, and other contaminants. Switch buttons are provided for easy operation, allowing users to start, stop, and adjust the machine’s settings. Additionally, there are cooling water and gas protection joints. The cooling water, flowing through the 6mm water pipes (in and out), forms a circulation system that cools the internal components, especially those that generate heat during the laser – emitting process. The gas protection joints are connected to a source of protective gas, such as argon, nitrogen, or filtered compressed air, which is used to protect the cleaning area from oxidation and other environmental factors.

Working Principle

The working principle of a portable handheld laser cleaning machine is based on the interaction between the laser beam and the contaminants on the surface. When the laser beam is emitted, it is absorbed by the coatings, rust, or other unwanted materials. The energy of the laser causes these materials to heat up rapidly, vaporize, or break into small particles. The high – pressure protective gas then blows away these vaporized or fragmented contaminants, leaving the surface clean. This non – contact process ensures that the underlying substrate remains undamaged, making it suitable for cleaning delicate or valuable items.

Connection Checks

• Periodically check the water and air connections of your portable handheld laser cleaner to ensure that they are properly connected and free of leaks. This is because leaks in the water system can not only damage internal components, but can also affect cooling efficiency and cause the machine to overheat.
• In addition, the external protective gas pressure should be monitored regularly to ensure that it meets the requirements (typically between 0.5 – 0.8MPa). This is because if the pressure is too low, it may not provide sufficient protection during the cleaning process, while too high a pressure can lead to unstable cleaning operations.

Cleaning of the Gun Body

• Keep the body of the portable handheld laser cleaner clean. The surface can be wiped with a special dust-free cotton swab or a rag moistened with anhydrous ethanol. This not only keeps the machine looking clean, but also helps to prevent dust and debris from accumulating so that it does not get into the internal components.
• You should also check the red light emitted by the machine. If you notice black spots when observing the red light, it may indicate that the lens is contaminated. In this case, check the protective lens for damage. If the lens is damaged, the damaged protective lens should be replaced immediately to ensure proper operation of the machine.

Working Environment Considerations

Take care to avoid using the Portable Handheld Laser Cleaner in high temperature and high humidity environments. Excessive temperatures can cause internal components to expand, which may result in misalignment or damage, while high humidity environments can cause condensation inside the machine, which can short-circuit electrical components or damage the optical system. If the user must use the machine in such an environment, appropriate measures should be taken, such as using a dehumidifier or providing additional means of cooling.

Cooling System Maintenance

• The cooling system is a critical part of the portable handheld laser cleaner.
• Care needs to be taken to use only pure water as the coolant.
• Before starting the cooling system, carefully inspect the entire water system and fittings for any signs of leakage.
• It is important to ensure that the cooling system is working properly and that the water temperature should be at least 18 degrees Celsius before turning on the laser.
• Check the water level regularly and add water as needed. It is recommended to change the water every three months to maintain cooling efficiency.
• In addition, clean the cooling fan regularly to prevent dust from clogging the fan and reducing its ability to dissipate heat.

Critical Maintenance Intervals

Power and Cleaning Capacity

Consider the power of the laser cleaner. Commonly used laser cleaners typically range from 1000W to 3000W.

For light duty cleaning tasks, such as cleaning small parts or removing thin layers of paint, a lower power machine (around 1000 – 1500W) may be sufficient. But for heavy-duty applications, such as removing thick rust or stubborn coatings, a higher-powered machine (2,000 – 3,000 Watts) is more suitable.
In addition the cleaning capacity is also related to the power and the size of the cleaning area that can be covered by the machine in a given time.
