How to Choose 30W, 40W or 60W CO2 Laser Power
The correct laser power should be selected according to the marking material, expected contrast, engraving depth and production speed. Higher power is not always necessary for every application. For fine surface marking, stable parameter control and proper focusing are often more important than simply increasing wattage.
- 30W CO2 laser marking machine: suitable for light surface marking on paper, cardboard, leather, thin wood, garment labels and small packaging items.
- 40W CO2 laser marking machine: a balanced choice for acrylic, wood, leather, packaging boxes and batch marking where better speed and contrast are required.
- 60W CO2 laser marking machine: suitable for deeper engraving, higher-speed production and larger marking areas on thicker or more demanding non-metal materials.
CO2 Laser Marking Machine vs Fiber Laser Marking Machine
CO2 and fiber laser marking machines are used for different materials. A CO2 laser marker is usually selected for wood, acrylic, leather, paper, glass, ceramic and other non-metal materials. A fiber laser marking machine is normally better for stainless steel, aluminum, brass, copper, tools, nameplates and many metal parts.
If the workpiece is bare metal, fiber laser is usually the better choice. If the workpiece is wood, acrylic, leather, paper packaging or glass, CO2 laser is normally more suitable. For coated metal surfaces, CO2 laser can sometimes remove the paint or coating layer, but the final result should be confirmed by sample testing.
Core Parts of CO2 Laser Marking System
EZCAD2 Control System and File Compatibility
The machine can be equipped with a BJJCZ control board and EZCAD2 software for stable galvo laser marking control. Operators can import vector files and image files from common design software such as AutoCAD, CorelDRAW, Adobe Illustrator and Photoshop. The system supports text, logos, serial numbers, barcodes, QR codes, automatic numbering and batch coding.
For production use, Vank Laser can provide basic parameter guidance according to the buyer’s marking material, marking content and expected output. Proper parameter setting helps improve marking contrast, reduce burning marks and maintain consistent results during repeated batch production.
Preview Box Mode
Four red-light lines form a preview box on the workpiece, allowing the operator to check marking position and content size before processing. This helps reduce positioning errors and unnecessary material waste.
Outer Contour Mode
The red-light outline shows the external contour of the marking content, helping operators confirm whether the logo, code or text fits within the product surface before marking starts.
CO2 Laser Source
The CO2 laser source works at 10.6 μm wavelength and is suitable for many organic and non-metal materials. Different power options are available for surface marking, shallow engraving and higher-speed production.
BJJCZ Laser Control Card
The control card supports stable marking control, file import, parameter adjustment and production operation. It is widely used in galvo laser marking systems for repeatable marking quality.
