Removing thick, stubborn rust requires smart adjustments to maximize your laser cleaner’s potential.
For severe corrosion, the Chinacnczone 1500W Continuous Handheld Laser Cleaner excels—if optimized properly. Here’s how to set it up:
1️⃣ Boost Power & Focus the Beam
Thick rust demands maximum energy density. Crank the power to 100% (1500W) to blast through dense layers.
Simultaneously, reduce the scanning width (spot size) using the machine’s adjustable optical head.
A tighter beam (e.g., 5–10mm vs. 20mm) concentrates heat, vaporizing rust more aggressively without overheating the base metal. This prevents superficial cleaning and ensures deep ablation.
2️⃣ Slow, Multi-Pass Strategy
Don’t force removal in one sweep. Make 3–5 slower passes over the same area.
-
First pass: Loosens the top crust.
-
Subsequent passes: Penetrate deeper layers.
Pause briefly between passes to let residue dissipate and avoid heat buildup. Adjust speed: 500–1000 mm/min for severe rust (vs. 2000+ mm/min for light cleaning).
⚙️ Pro Tips
-
Frequency: Use higher frequencies (e.g., 80–100 kHz) for fine control on uneven surfaces.
-
Angle: Hold the laser head 70–90° to the surface for optimal energy transfer.
-
Safety: Always wear protective goggles and ensure ventilation—thick rust creates more particulate debris.
