Buying Guide

How to choose

Pulsed 200–300W: low-heat, precise removal for sensitive substrates and thin layers (molds, restoration, selective coating removal).

Water-cooled CW 1000–6000W: highest throughput for large areas and heavy rust/paint; supports 4-in-1 / 3-in-1 multi-functions.

Frequently Asked Questions

Answers from the perspective of a factory manufacturer of fiber laser cleaning systems.

  • Q Will laser cleaning damage the substrate?

    Pulsed 200–300W delivers high peak power with short pulses so energy couples mainly with contaminants rather than base metal—keeping the heat-affected zone minimal. With water-cooled CW 1–6kW, we tune spot size, scan speed and wobble amplitude; with correct parameters the substrate stays intact while removal rate is high.

    We recommend quick coupon tests on your actual material to lock safe parameters.

  • Q Which contaminants and layers can be removed efficiently?

    Typical cases: rust/oxide, paint and coatings, oil/grease, weld-prep oxides, adhesives, and mold residues. Pulsed units suit thin, delicate layers and precision areas; CW excels on thick rust, heavy paint, and large surfaces.

  • Q How do I choose between 200–300W pulsed and 1–6kW CW?

    Pick 200–300W pulsed for sensitive substrates, small parts or selective cleaning. Choose 1–6kW CW for high throughput on large parts or thick coatings. If you also need welding/cutting/polishing, our CW platform supports 4-in-1 / 3-in-1 with quick-change heads.

  • Q What safety and environmental controls are required?

    Systems are Class 4 lasers. Use wavelength-rated eyewear, interlocked enclosures or safe zones, SOPs and operator training. Provide effective fume extraction and filtration to capture particulates and vapors; never operate unattended.

  • Q What maintenance and consumables are involved?

    Fiber lasers have few wear parts. Routine tasks: nozzle care, protective window cleaning/replacement, lens inspection; for CW models, chiller water maintenance. No chemical consumables—main costs are electricity and filter media.

  • Q How does laser cleaning compare with chemicals, dry-ice, or sandblasting?

    Laser is precise, dry, and consumable-free with minimal substrate impact; chemicals require handling/disposal; dry-ice has logistics/noise limits; sandblasting is aggressive and can damage surfaces. Many factories use laser for critical areas and keep other methods for secondary work.
