Thank you for your feedback — and we’re sorry to hear the warning label arrived oriented incorrectly. We understand how frustrating that can be, especially when you followed the width x height format as listed on our site.
You can find more information on our web, so please take a look.
While most of our laser window coverings are larger (making orientation more apparent), we recognize that in more compact configurations, it can be less intuitive. For any future orders, you're always welcome to submit a photo or drawing if you’d like the warning label placed in a specific position — we’re happy to accommodate.
We want to make this right. Our team is reaching out to you privately and would be happy to send a corrected version so it’s to your satisfaction.
We do appreciate your note that the fit was perfect and that the magnetic mounting is working well — and we truly value your feedback as it helps us continue to improve.

Hi Gideon,
Thank you for sharing your experience. We’re sorry the Shade 5 filter didn’t work out for your setup.
Shade 5 is our most protective welding plate—it’s designed to block the intense white-light from the weld arc and a broad range of laser wavelengths. The trade-off is very low visible-light transmission, which can dim or completely block the low-power preview or alignment beams on many handheld welders.
If seeing the alignment beam while you work is critical, Shade 3 offers a better balance between visibility and protection. Just keep in mind that it does let in more light overall, so it provides less protection than Shade 5. Choosing Shade 3 is a matter of accepting that trade-off to maintain a clear view of the aiming beam.
We’d be happy to:
Exchange your Shade 5 plate for a Shade 3 at no cost, or
Refund your purchase in full if you’d prefer to return it.
We’ve also added a note to our product documentation clarifying how each shade affects preview-laser visibility so future buyers can pick the right option from the start.
Please let us know which solution you’d like (or if there’s anything else we can do) and we’ll make it right.
Thank you again for helping us improve.

Laser Ablation and Its Applications
Laser ablation is the process of removing material from a surface using the concentrated power of a laser beam. It is used in various industrial applications like:
- Surface cleaning
- Laser paint removal, or coating removal
- Laser oxide and rust removal
- Laser marking for traceability, or logo engraving
- Laser texturing (also known as structuring or roughening) to improve adhesion before processes like thermal spray coating and adhesive bonding
- Laser cutting and drilling
- Laser welding
5 Considerations to Choose the Right Laser Ablation Machine
Before choosing a laser ablation machine, you should go over the following considerations. They will guide you in choosing the right type of equipment for your application.
1. Continuous vs. Pulsed Laser Beams
Laser beams can either be pulsed at a set repetition rate to reach high energy peaks, or continuous to release the same energy level all the time. Pulsed lasers are generally better for the ablation process because of their higher peak power.
The heat affected zone of pulsed lasers is also much lower, which makes the process easier to control to prevent damaging parts. Continuous-wave lasers can also be used for ablation and material removal, but only if the laser intensity is high enough.
- Pulsed lasers are used for laser marking, laser cleaning, laser texturing, and laser welding.
- Continuous lasers are used for laser welding and laser cutting.
For welding applications (which is where there is an overlap), thin or sensitive parts usually require a pulsed laser, as they generate a lower heat affected zone and shallower welds. For deep welds, continuous-wave lasers are better.
2. Laser Power that Meets Your Cycle Time
The laser power is the average amount of energy that can be released during one second by the laser. Higher power lasers can ablate more material over the same time. In the case of pulsed lasers, this often means that more laser pulses are released during the same time, but the pulses themselves are not necessarily more powerful.
Laserax offers pulsed lasers that range between 10W and 3,000W of average power. Here’s how each power level is used:

3. Laser Source Based on Your Material
The type of material you will be processing determines the laser source needed in your machine. This is because different types of laser sources generate different wavelengths, and different materials absorb wavelengths differently. Examples of laser sources include CO2 lasers and fiber lasers.
The graph below shows how different metals absorb wavelengths and will help you understand if the laser you’re looking at is appropriate for your application:
At Laserax, our fiber lasers are doped with ytterbium to generate a wavelength of nm. This wavelength can effectively process most metals and is used in all our laser ablation machines to engrave, clean, texture, and weld metals.
4. Multimode Lasers for Ultra-High-Speed Cleaning
The optical cable in fiber laser machines can either be multimode or single mode. Each type offers different advantages and is used for different applications.
- Single mode lasers have a smaller spot size, allowing them to focus more energy in a smaller area. They can therefore etch and ablate substrates more effectively. They are used for laser marking, laser texturing, laser cleaning, and laser welding. Most of our turnkey solutions for laser ablation use single mode lasers.
- Multimode lasers have a larger spot size. This allows them to remove material from large surfaces faster. The fiber cable core is also larger, which allows more energy to pass through without overheating the laser. This makes it possible to reach higher power levels. Our ultra-high-power laser cleaning system is an example of a multimode laser.
5. The Right Laser Options and Automation Features
Laser ablation machines need to have the right options and automation features for your needs. Common features include:
- Laser safety to protect operators on the shop floor
- Dust and fume management to keep a clean air and prevent dust accumulation
- Gantry systems to cover larger areas
- Rotary tables to minimize idle time
- Vision systems to account for positioning variations
