The UV laser marking machine utilizes a 355nm laser wavelength and operates as a cold light source, often referred to as a “cold light laser marker.” Its extremely small focused spot and minimal heat-affected zone make it ideal for fine processing of heat-sensitive materials, enabling ultra-fine marking, engraving, and marking on specialized materials. The UV laser marking machine’s wide material applicability effectively addresses the challenges encountered when using fiber, green, CO2, and MOPA laser marking machines on certain materials, where achieving delicate and satisfactory results can be difficult. To ensure your UV laser marking machine operates efficiently and has a long service life, consider the following important points during operation:
1.Working Environment Requirements:
While the processing results of the UV laser marking machine are generally not affected by environmental factors, maintaining a suitable working environment is crucial. The ideal processing environment should adhere to these guidelines:
- Temperature: 10℃ – 35℃ (50°F – 95°F)
- Humidity: Within standard limits.
- Cleanliness: Clean and tidy, with a work surface free from contaminants.
2.Power Supply Requirements:
- Provide a dedicated AC single-phase power supply with a minimum capacity of 2500W.
- The machine’s main power cord must be connected to a circuit breaker for protection.
- The use of three-prong plugs is strictly prohibited.
- Ensure the main power supply has a reliable ground connection, avoiding any loose connections.
3.Pre-Operation Inspection:
Before each processing session, conduct a thorough inspection of the UV laser marking machine, including:
- Cooling System: Verify proper operation.
- Optical Path System: Ensure the optical path is unobstructed and in good condition.
- Field Lens (Scanning Lens): Clean and inspect for any damage.
4.Cooling System Maintenance:
- It is recommended to use deionized water in the circulating water tank. If deionized water is unavailable, distilled water can be used as a substitute.
- Replace the circulating cooling water regularly (at least every two weeks is recommended) to maintain optimal laser output efficiency.
Important Note:
UV laser marking machines are generally more expensive than other types of marking machines and have lower power output. Therefore, they are not recommended for marking metal hardware or other materials that require high power. Consequently, paying close attention to daily operation and equipment maintenance is essential to maximize your return on investment in your UV laser marking machine.
