500W Pulsed Laser Cleaning Machine
The ApexLase ARC500 delivers 500W average pulsed power with 15mJ peak pulse energy — a significant step up in ablation capability from the 300W ARC300, while maintaining the pulsed technology's substrate-safe characteristics. The choice for heavier rust, thick industrial coatings, marine component cleaning, and structural steel surface preparation.
15mJ — Why Pulse Energy Matters
The ARC500's 15mJ pulse energy is three times that of the ARC300. In pulsed laser cleaning, pulse energy (mJ) is the primary determinant of how aggressively the laser can ablate thick or tenacious contamination. Higher mJ means the laser can tackle heavier rust layers, thicker coatings, and denser oxide deposits that a 5mJ system would require multiple passes to remove. This translates directly to faster cleaning on demanding applications, while still protecting the substrate beneath.
Who the ARC500 is for
Heavy rust on structural steel
Where the ARC300 needs multiple passes, the ARC500's higher pulse energy clears heavy rust more decisively. Suitable for fabricated sections, brackets, frames, and structural components.
Thick coating removal
Epoxy, powder coat, and heavy industrial primers that resist lower energy systems are more efficiently removed at 15mJ. Still substrate-safe for most metals.
Marine component cleaning
Marine environments produce heavy corrosion that demands more energy per pulse. The ARC500 handles anti-fouling, rust, and salt-accelerated corrosion from boat fittings, shaft components, and deck hardware.
Fabrication and workshop
For workshops cleaning a volume of fabricated parts — prep for coating, weld oxide removal, or batch degreasing — the ARC500's throughput advantage over the 300W unit is meaningful.
ARC500 vs ARC300 vs CW — Choosing
If your primary applications involve delicate substrates and light contamination, the ARC300 is sufficient. If you regularly face heavy rust or thick coatings and throughput matters, the ARC500 is the better choice. If you need to clean large areas of heavy industrial contamination as fast as possible and the substrate can tolerate more heat, a CW system (ION1000 or above) will outperform both pulsed units on throughput.
