Can you provide real laser source and nameplate photos?

Yes, of course. If you need it, please let us know. We can provide real laser source and nameplate photos during production to ensure transparency and authenticity.

Can the machine remove car oil stains and carbon deposits?

Yes, it can effectively remove oil stains and carbon deposits from metal surfaces. The final result depends on the thickness, adhesion level, and oxidation degree of the contamination.

For automotive repair and maintenance, we recommend the Scotle pulsed laser cleaning machine, as it provides higher precision and better surface protection for sensitive components.

What is the cleaning efficiency?

It depends on different application scenarios and handheld operation conditions. The following is laboratory data on rust removal and cleaning efficiency, for reference only. Please refer to actual working conditions for accurate performance.

Continuous Laser Power	Single Cleaning Thickness	Cleaning Efficiency
1500W	1–2 mm	15–20 m²/hour
2000W	2–2.5 mm	20–25 m²/hour
3000W	3–4 mm	35–40 m²/hour

What materials can they clean?

CW laser cleaning machine mainly used for removing metal rust and oil stains. It has also been tested and can remove rubber residues.

Power Supply & Machine Configuration

What are the voltage and current requirements for different power models (e.g., 2500W)

Typically, the required power supply can be estimated at approximately three times the laser power. For water-cooled systems, an industrial chiller is also required, and its power consumption is generally close to that of the laser source.

For the European market, most standard 220V household power supplies are not suitable for high-power laser cleaning systems above 2000W. A 2500W machine typically requires a very high current (over 40A), which exceeds normal residential electrical capacity. In practice, this may lead to circuit overload or breaker tripping during operation.

Therefore, for most European users working in workshops, garages, or on-site maintenance environments, 1500W and 2000W laser cleaning machines are the more practical and stable choices, offering a better balance between performance, power availability, and operational safety without requiring complex electrical upgrades.

What are the requirements for using a generator power supply?

The generator must be equipped with a voltage stabilizing function.

What is the difference between single wobble and dual wobble Cleaning heads?

A single-wobble head can only produce a horizontal line beam. A dual-wobble head currently supports 9 different beam patterns, providing better performance on irregular or uneven surface shapes.

Does the CW laser cleaning machine need gas?

Only clean compressed air is required.
If the ambient air is not clean, it should be filtered into dry and clean compressed air before use.

Maintenance & Cooling System

What is the laser lifetime and continuous working time?

There is no fixed absolute lifespan in terms of working hours. The performance is mainly affected by power degradation, which is closely related to the user’s operating frequency and usage conditions.

For normal industrial use (6 days per week, 8 hours per day), the annual power degradation is approximately 3%–5%.

How to add antifreeze to the water-cooled laser chiller?

The standard mixing ratio for laser equipment antifreeze is:
30% dedicated antifreeze + 70% deionized water (or distilled water), suitable for environments down to approximately -10°C.

For lower temperatures, the ratio can be adjusted accordingly, but generally should not exceed 50% antifreeze. (For extreme low temperatures ≤ -20°C, a 40%–50% mixture may be used.)

Ambient temperature 0°C to -10°C:
20%–30% antifreeze + 70%–80% deionized/distilled water
Ambient temperature -10°C to -20°C:
30%–40% antifreeze + 60%–70% deionized/distilled water
Ambient temperature ≤ -20°C:
40%–50% antifreeze + 50%–60% deionized/distilled water (only in special cases, and equipment compatibility must be confirmed)

⚠️ Important notes:

Tap water is strictly prohibited. Always use deionized or distilled water to prevent scale buildup and blockage in precision water channels.
Do not mix different brands or types of antifreeze. Prefer laser-grade recommended coolants (e.g., Clariant, Ice-type coolant, etc.).
Always mix thoroughly in a separate container before filling into the chiller. Never pour pure antifreeze directly into the system.

What refrigerant is used in the water-cooled Laser Cleaner?

Currently, R32 is used, which complies with EU environmental protection regulations.

What water should be used in the chiller?

It should be filled with purified water or distilled water.

Warranty & After-Sales Support

What certifications does the machine have?

The Scotle laser cleaning machines are certified with international safety and quality standards, including:

CE Certification (EU safety compliance)
RoHS Certification (environmental compliance)
FDA Certification (U.S. compliance for laser equipment)
IEC 60825-1 Certification (laser safety standard)

These certifications ensure that the machine meets strict international requirements for safety, environmental protection, and laser operation reliability.

What warranty does Scotle provide?

The Scotle laser cleaning machines comes with a comprehensive warranty and lifetime support policy:

Complete machine: 1-year warranty
