Key Advantages:

• Advanced water cooling system for superior heat dissipation

• Supports higher laser source power

• Higher single-pulse energy

• Suitable for long continuous operation

• Industrial cabinet structure for stability

Why Water Cooling?

Air cooling laser cleaning machines have power limitations due to heat dissipation constraints. A water cooling pulse laser cleaning machine overcomes this limitation, enabling:

• Faster cleaning speed

• Removal of thick rust and heavy coatings

• Large-area industrial surface treatment

Typical Applications:

• Automotive manufacturing

• Heavy machinery industry

• Steel plants and shipyards

• Production lines and automation systems

This high-power water cooling cabinet laser cleaning machine is the preferred solution for industrial and large-scale cleaning tasks.

4. Handheld CW Air Cooling Laser Cleaning Machine

The handheld CW air cooling laser cleaning machine adopts a continuous wave (CW) laser source, which is fundamentally different from pulse laser cleaning technology in both energy output mode and cleaning behavior. This type of laser cleaning machine is mainly designed for high-efficiency, continuous surface treatment, especially where cleaning speed is a priority.

CW Laser vs Pulse Laser Cleaning – Technical Differences

1. Laser Output Mode

• CW (Continuous Wave) Laser Cleaning
  The CW laser outputs continuous and uninterrupted laser energy, allowing nonstop scanning across the surface. This makes CW laser cleaning machines highly efficient for large-area and fast cleaning applications.

• Pulse Laser Cleaning
  Pulse laser cleaning delivers high-energy laser bursts in extremely short durations. Energy is precisely controlled in each pulse, enabling accurate material removal with minimal heat accumulation.

2. Thermal Impact on the Base Material

• Pulse Laser Cleaning Machine
  Pulse laser cleaning is non-thermal or low-thermal in nature. Because the laser energy is released in ultra-short pulses, heat does not have enough time to transfer into the base material.
  ✅ Result: No deformation, no micro-cracks, and no damage to the substrate.

• CW Laser Cleaning Machine
  CW laser cleaning involves continuous thermal input. While this enables faster cleaning, it also introduces higher heat accumulation on the surface.
  ⚠️ Result: Cleaning parameters must be carefully controlled to avoid overheating or affecting sensitive base materials.

3. Cleaning Efficiency & Working Speed

• CW Air Cooling Laser Cleaning Machine
  Continuous laser output enables high-speed surface scanning, making CW laser cleaning machines ideal for:

• Fast production lines

• Large-area cleaning

• High-efficiency surface pretreatment

• Pulse Laser Cleaning Machine
  Pulse laser cleaning focuses on precision rather than speed, offering controlled material removal and superior cleaning quality for demanding applications.

4. Base Material Protection Capability

• Pulse Laser Cleaning
  Designed specifically for base material protection, pulse laser cleaning is suitable for:

• Precision metal surfaces

• Thin materials

• Molds and tools

• Heritage and restoration work

• CW Laser Cleaning
  CW laser cleaning prioritizes efficiency over precision, and is best suited for robust materials where slight thermal influence is acceptable.

Key Advantages of Handheld CW Air Cooling Laser Cleaning Machine

1. Continuous Laser Output for High Efficiency
   Enables uninterrupted cleaning, significantly improving productivity for large surfaces.

2. Higher Cleaning Speed
   Ideal for applications requiring fast surface preparation and short processing time.

3. Simple System Structure
   CW laser systems have fewer control parameters, resulting in easier operation and lower learning costs.

4. Air Cooling Design

• Compact and lightweight structure

• No water chiller required

• Lower maintenance cost

5. Handheld Operation
   Provides flexibility for on-site, manual, and mobile laser cleaning applications.

Typical Applications of CW Air Cooling Laser Cleaning Machine

• Oil and grease removal

• Light rust and oxide layer cleaning

• Surface pretreatment before welding

• Surface preparation before coating or painting

• Production-line auxiliary cleaning

When to Choose CW Laser Cleaning vs Pulse Laser Cleaning

Summary

The handheld CW air cooling laser cleaning machine is a powerful solution for high-efficiency, continuous surface cleaning. While CW laser cleaning delivers faster processing speed through continuous laser output, it introduces higher thermal input and therefore requires proper parameter control.

In contrast, pulse laser cleaning machines excel in non-damaging, precision cleaning, making them the preferred choice when base material protection is critical.

By understanding the fundamental differences between CW and pulse laser cleaning technologies, users can select the most suitable laser cleaning machine for their specific application, balancing efficiency, safety, and cleaning quality.

5. Handheld CW Water Cooling Laser Cleaning Machine

The handheld CW water cooling laser cleaning machine combines continuous wave laser technology with a water cooling system, allowing higher power levels and improved thermal control.

Key Advantages:

• Higher CW laser power capability

• Water cooling ensures stable continuous output

• Faster cleaning speed on large surfaces

• Suitable for heavy industrial environments

Typical Applications:

• Large steel structures

• Thick coatings removal

• Continuous production cleaning lines

Compared with air-cooled CW systems, the water cooling CW laser cleaning machine offers better stability, longer working time, and higher efficiency.
