FAQ

Safety and equipment longevity are the most critical factors when operating a laser system. While lasers are incredibly versatile, certain substrates can release lethal gases, catch fire instantly, or permanently corrode your machine’s optics. To ensure a safe workspace, every operator must be able to answer: Which materials are not suitable for laser cutting and engraving?

When expanding an industrial workshop or refining a product line, the most critical technical question is often: Can a ETL laser machine engrave and mark metal? The short answer is yes. ETL systems are designed to handle a vast array of metallic substrates, though the specific results depend on whether you are utilizing Fiber, CO2, or UV laser technology.

This guide breaks down the technical requirements for Fiber, CO2, and UV systems to help you answer the question: Which laser power of laser machine do I need for my application?

While both processes fall under the umbrella of “laser processing,” the short answer is no. The equipment used for FPC (Flexible Printed Circuit) processing is significantly different from the machinery used for laser cutting stainless steel in terms of wavelength, power, and thermal impact.

Your 7W Artilume T1 is more than sufficient for making foam inserts for Altoids tins. As long as you keep the foam thickness between 2–4mm and use low power, high speed, and air assist, you will get clean, full cuts without melting or messy edges. If the foam is thicker than 5mm, you will need a more powerful laser or switch to thinner foam—7W is not enough to cut thick foam cleanly.

How to disassemble and install the vibrating mirror of the laser marking machine，the “Vibrating Mirror” (Galvanometer or Galvo Head) is the precision heart of the machine. It contains two high-speed mirrors that direct the laser beam. Because these are sensitive optical and electronic components, you must handle them with extreme care.

What are the precautions for fiber laser cutting of rusty plates？Understanding the precautions for fiber laser cutting of rusty plates is essential for maintaining sheet metal processing quality. This guide analyzes how iron oxide affects laser absorption and addresses risks such as reduced cutting speeds, rough edge finishes, and back-reflection damage to optics. We recommend pre-treatment via grinding or laser cleaning, optimizing piercing parameters, and fine-tuning focal position and gas pressure based on thickness. By applying these technical adjustments, you can effectively reduce scrap rates, protect critical laser head components, and maximize the utility of rusted metal materials.

How to solve the problem of edge burning in fiber laser cutting machines?Edge burning (over-burning) is a common challenge in fiber laser cutting, particularly when dealing with carbon steel or sharp corners. It occurs when excessive heat accumulates in a small area, causing a runaway exothermic reaction with the oxygen assist gas.

Yes, a laser cutting machine emits radiation, but it is important to distinguish between the type of radiation it emits and the “ionizing” radiation associated with X-rays or nuclear material.

How to quickly solve the malfunction of a handheld laser welding machine? Solving the malfunction of a handheld laser welding machine usually involves a process of elimination starting with the most common “safety interlock” issues before moving to complex hardware faults.

To choose the right CO2 laser marking machine, you need to match the machine’s specific configuration to your business needs. The term “CO2 Laser” covers a wide range of machines, but for marking applications, the most critical choice is between the Laser Source Type (Glass vs. Metal) and the Machine Structure (Galvo vs. Gantry).

Proper maintenance is critical for extending the lifespan of a CO2 laser marking machine, which can last for over 10 years if well-maintained.

Here is an introduction to the three most common classifications: Fiber, CO2 Laser Marking Machines, and UV Laser Marking Machines.
