Continuous Wave Laser Cleaning Machines

Stripping heavy rust, mill scale, or thick paint from structural steel, trailers, or equipment frames? A continuous wave laser cleaning machine holds a steady fiber laser beam on the surface instead of firing short pulses, so it clears large, heavily corroded areas much faster than a pulsed unit. That makes a CW laser cleaner the production tool for robust metal, where throughput matters more than a delicate finish.

At The Maker's Chest, we carry continuous wave laser rust removal machines from 1500W to 6000W by Herolaser, Hanten, and DenaliWeld. Hanten rates its 1500W cleaners at 25–30 m² per hour on rust up to 50 µm thick, and its 6000W at 100–120 m². Because continuous sources cost far less per watt, a 1500W or 2000W unit can cost less than a 300W pulsed cleaner, and our team offers expert help matching power, cooling, and voltage to your shop.

Choose the Right Continuous Wave Laser Cleaning Machine for Heavy-Duty Jobs

Frequently Asked Questions

Will a continuous wave laser cleaner damage or warp thin metal?

It can. A continuous wave laser cleaner delivers steady heat rather than short pulses, so long dwell times on thin sheet, aluminum panels, or polished stainless can warp, discolor, or roughen the surface. On thicker structural steel, castings, frames, and heavy plate, that heat is absorbed without visible damage when speed and power are set correctly. If the part is thin, finished, or irreplaceable, choose a pulsed cleaner instead; a CW machine is built for robust metal where cleaning speed is the priority.

How many square meters per hour can a CW laser cleaning machine clean?

It depends on wattage and rust thickness. Hanten's laboratory data rates its 1500W continuous cleaners at 25–30 m² per hour on rust up to 50 µm, its 2000W at 35–40 m², its 3000W at 50–60 m², and its 6000W at 100–120 m² per hour. Throughput drops sharply as rust gets thicker: on rust over 100 µm, the same 1500W machine falls to about 8 m² per hour and the 3000W to about 20 m². Treat these as best-case figures for flat, accessible steel.

Do continuous wave laser cleaners need a water chiller?

Not always. The Herolaser 1500W and 2000W and the DenaliWeld Jet 2000 in this collection are air-cooled and run without any chiller, which keeps them lighter and simpler to move between jobs. Hanten's SEAL2 and 6000W machines use water cooling, but the water-cooling system is built into the cabinet, so there is no separate chiller to buy or plumb in. Water-cooled continuous wave laser cleaners are better suited to long industrial shifts, while air-cooled units suit mobile and intermittent work.

What power supply does a continuous wave laser cleaning machine need?

Most 1500W and 2000W continuous wave machines in this collection run on 220V single-phase power, including the DenaliWeld Jet 2000 and the Hanten SEAL2 1500W and 2000W. Hanten specifies 380V industrial power for its 3000W SEAL2, so confirm three-phase service before ordering a 3000W or 6000W system. Check your shop's voltage before choosing a wattage tier. For heavy-dust or continuous work, Hanten also recommends an air compressor with an oil-water separator, and every laser cleaning setup needs fume extraction and laser-rated safety eyewear.

Which CW laser cleaner wattage should I choose: 1500W, 2000W, 3000W, or 6000W?

Choose 1500W for maintenance, restoration, and intermittent rust and paint removal in a smaller shop. Step to 2000W when you clean often enough that speed matters; it runs about a third faster than 1500W and is the most power available on 220V in Hanten's SEAL2 range. Choose 3000W for large frames and daily production cleaning, and 6000W for ship hulls, storage tanks, bridges, and steel structures measured in hundreds of square meters.
