Laser cleaning machines

Laser rust removal: pulsed against continuous, and what each one leaves behind

A laser cleaning machine strips rust, paint and oil by vaporising the layer above the metal, and the specification that decides what it can be used on is whether the source is pulsed or continuous rather than how many watts it has. Laser Oracle records the source type, the power and the scanning width each listing states, and counts the listings that state none of them.

All machines

Of the 13 we currently hold, nine state supply voltage and phase and four do not. Live prices start at $5,399 and refresh every three hours, so no figure on this page is more than 24 hours old.

What Laser Oracle counted hereThe figures above, in full, with what they do and do not prove

Laser Oracle tracks 13 laser cleaning machines on Amazon and measures every listing against the specifications that actually decide the purchase. Of the 13 we currently hold, nine state supply voltage and phase and four do not. That gap is the finding. These are not obscure figures: they are the ones a buyer needs before choosing, and they are missing from the listing that is doing the selling. Prices and category rankings come from the Amazon Product Advertising API and are refreshed every three hours, so no figure here is more than 24 hours old; all 13 carry a live price at the moment this page was built. A listing that omits a specification has not told us the product lacks it.

What is selling on Amazon

Ordered by Amazon’s own category placement weighted by price, not by us.

We may earn a commission from these links, at no extra cost to you.

“Stated in the listing” means the seller printed the figure somewhere in the title or the bullets. It is not a verification, and “not published” is a fact about the listing rather than about the product.

What the listings state, and what they leave out

Counted across every listing we track in this category, when this page was built.

How many laser cleaning machines listings state each specification
SpecificationListings stating itWhy it decides the purchase
Pulsed or continuous source13 of 13A continuous source is faster and hotter and will mark the metal under the rust. A pulsed one lifts the oxide and leaves the substrate, which is why a 300W pulse machine costs more than a 2000W continuous one. Wattage alone does not tell you which you are buying.
Laser power13 of 13Power sets how fast an area is cleared. On these machines it runs from 200W to 2000W at three times the price, and it is the number every listing leads with.
Scanning width11 of 13No scanning width statedThe width the head clears in one sweep is what turns power into a rate of work. A machine quoting 2000W and no scan width has left out half of the throughput figure.
Supply voltage and phase9 of 13No supply voltage statedThese are 220V industrial tools and a standard US general-purpose outlet is 120V. Whether the listing says so decides whether the machine runs on the day it arrives or waits for an electrician.

A count of what the listing says is not a count of what the product does. A seller who omits a figure has told us nothing about the product, only about the listing, and these rows are worded that way on purpose.

What each maker publishes about its own machine

These are sold as portable and the gun is; the maker puts the continuous machine at 170kg and cools it with an industrial chiller. Of the three machines here whose own documentation we have read, one lists a 110 V option, and it is a pulsed machine, at a fraction of the power and under half the scanning width. Every figure below is quoted from the manufacturer’s own documentation, with the date it was read.

How these figures were producedSources, refresh cadence, and what we do not claim

Nothing on this page is a review. Laser Oracle does not test machines and does not claim to. Where a manufacturer publishes a specification document, this page quotes it and names the page and the date it was read; three of the machines here have one. For the rest, the listing doing the selling is the only thing there is to measure. Every claim quoted from a listing is the seller's own wording, and the counts are our measurement of those listings rather than of the products themselves. Prices and category rankings are read from the Amazon Product Advertising API and refreshed every three hours. Listing wording is read on the date shown on each product page, and every count is taken again whenever the catalogue changes.

Questions people ask

How much does a laser cleaning machine cost?
The machines Amazon stocks run $5,399 to $20,599 today, re-read every three hours. Power and source type set the price far more than brand does: a 300W pulsed machine costs more than a 2000W continuous one, because pulsing is what lets it clean without marking the metal underneath. Add a 220V circuit, extraction and rated eye protection to whatever the machine costs.
Do laser cleaning machines really work?
Laser cleaning is established industrial practice and has been for decades; the machines here are that process at a price a small shop can reach. Laser Oracle has not run any of them and does not claim to. What is worth knowing before buying is that the makers publish very little: of the machines on this page, only Triumph publishes a specification sheet we have been able to read, and the rest are white-label listings whose seller wrote the only description that exists.
What are the disadvantages of laser cleaning?
Four, and no listing on Amazon states any of them. The machine is 220V and heavy, so it is portable in the sense that the gun is handheld and not in the sense that you carry it upstairs: Triumph puts its continuous machine at 170kg with an industrial chiller. It is slow on large areas compared with blasting, and the scanning width is what decides that rather than the wattage. It removes the coating as airborne particulate, so old paint may put lead into the air and extraction is not optional. And a continuous source at high power will discolour or warp thin material, which is what the pulsed machines cost more to avoid.
How does a laser remove rust?
The rust absorbs the beam far more readily than the metal beneath it, so the oxide layer heats, breaks its bond and blows off as dust while the steel stays where it is. That difference in absorption is the whole mechanism, and it is why the process cleans without abrasive, chemicals or a blast cabinet to contain them.
Pulsed or continuous: which one do I need?
A continuous source clears an area faster and puts heat into whatever sits under the layer being removed, which is fine on thick structural steel and wrong on thin sheet, plated parts or anything you intend to keep the surface of. A pulsed source delivers the same energy in very short bursts, so the layer lifts before the substrate warms. That is why a 300W pulsed machine costs more than a 2000W continuous one, and why the wattage on its own tells you very little.
Will it damage the metal underneath?
A correctly set pulsed machine should not, and that is the property the process is bought for. A continuous machine at high power on thin material will discolour it, warp it or strip plating, and no setting makes that entirely go away. The honest way to choose is by the thinnest and most delicate thing you intend to point it at rather than by the worst-rusted.
Can you plug one into a normal outlet?
Not a general-purpose US outlet. These are 220V tools and the larger ones want three phase. The electrician fitting a dedicated circuit is part of the purchase price, and it is the step most likely to delay a machine that has already been delivered.
What does the extracted rust do?
It becomes airborne particulate, and on a painted or plated surface it can carry whatever was in the coating. Extraction is not optional the way it sometimes is on a small engraver, and old paint in particular may contain lead. Check what you are removing before deciding what filtration the job needs.
