When want to use laser cleaner for rust removal or clean, one critical decision arises: Chinacnczone handheld pulse laser cleaner vs. continuous laser cleaner.
Both excel at removing rust, paint, oxides, and contaminants without chemicals or abrasives, but their core technologies suit different needs.
Let’s break down the key differences to help you choose wisely.
⚡️ Core Technology & Cleaning Mechanism
-
Chinacnczone Handheld Continuous Laser Cleaner:
Emits a steady, high-power laser beam (e.g., 1500W, 2000W, 3000W). Heat builds up rapidly on the surface, causing thick contaminants (rust, heavy paint) to vaporize or thermally peel off. Best for fast removal of thick layers (up to 2.5mm rust with 2000W). -
Chinacnczone Handheld Pulse Laser Cleaning Machine:
Delivers ultra-short, high-peak-power bursts (nanosecond pulses). Energy is absorbed instantly by the contaminant layer, causing rapid expansion/vaporization with minimal heat transfer to the substrate. Excels at precision cleaning, delicate surfaces, and thin/fragile contaminants without damaging the base material.

⚖️ Key Comparison Table
Feature | Continuous Wave (CW) Laser Cleaner | Pulse Laser Cleaner |
---|---|---|
Laser Output | Steady, high-power beam | Short, high-peak-power bursts |
Best For | Thick rust, paint, oxides (1-4mm) | Precision work, thin layers, delicate surfaces (art, electronics, stone) |
Thermal Impact | Higher (managed via scanning speed) | Very Low (minimal substrate heating) |
Cleaning Speed | High (15-40 m²/hr depending on power) | Moderate (adjustable via parameters) |
Precision & Control | Good for large areas | Excellent (fine spot control, less base damage risk) |
Beam Profile | Multi-mode (broader, flatter energy dist.) | Single-mode Gaussian (central energy peak) or optional Flat-top |
Cooling | Water Chiller Required (critical system) | Typically Air-Cooled (simpler setup) |
System Complexity | Higher (laser source + chiller) | Lower (more compact) |
Example Models | 1500W/2000W/3000W Mini Handheld | FW-200 (200W), FW-300 (300W) Pulse |
🎯 When to Choose a Continuous Laser Cleaner
-
You need maximum speed on heavy contamination: Removing thick rust, mill scale, or heavy paint coatings from large metal structures (ship hulls, tanks, structural steel).
-
Efficiency is paramount: Projects requiring high throughput (e.g., 20-25 m²/hr with 2000W).
-
The substrate is robust: Base materials like thick carbon steel can tolerate the higher thermal input.
-
Infrastructure allows for water cooling: You have space/power for the integrated water chiller system (requires distilled water + antifreeze in cold temps).
Chinacnczone Conituous Laser Cleaner Strengths: High power (up to 3000W), excellent efficiency for thick layers, robust industrial design.
🎯 When to Choose a Pulse Laser Cleaner
-
Precision and substrate protection are critical: Cleaning delicate artifacts, electronics, aerospace components, welds, or thin materials where heat damage is unacceptable.
-
Dealing with thin or loosely bonded contaminants: Light rust (yellow rust), oils, greases, soot, thin paints, or surface oxidation.
-
Working on sensitive materials: Stone, wood, glass, composites, or polished metals.
-
Mobility/Simplicity is key: Air-cooled systems are lighter, quieter, and don't require chillers or complex coolant maintenance.
-
Flexibility in spot profile needed (if Flat-top option): Truly uniform energy distribution for flawless cleaning on sensitive surfaces.
Chinacnczone Pulse Laser Cleaner Strengths: Minimal thermal impact, high precision, air-cooled convenience, ideal for restoration & fine work. Gaussian beam standard; Flat-top superior for zero-damage applications.
⚠️ Critical Safety Note (Applies to Both)
Both Continuous and Pulse cleaners from Chinacnczone are Class 4 Laser Products. This demands strict safety protocols:
-
Mandatory PPE: Laser safety goggles (OD 7+ for 1080nm), face shields, protective clothing, gloves.
-
Controlled Environment: Use laser safety curtains/barriers. Post warning signs. Restrict access.
-
Ventilation: Both generate fumes/particulates. Use extraction systems, especially indoors.
-
Fire Hazard: Remove flammables. Have fire extinguishers ready.
-
Training: Only trained personnel should operate the equipment.
-
Follow Start/Stop Sequences: Especially critical for Continuous systems (Chiller ON first/OFF last).
