You’ve just landed a custom engraving order for stainless steel tumblers, but your diode laser is struggling to leave a lasting mark. You need a tool that can handle metals with speed and precision, and the GWEIKE G2 Pro 30W fiber laser promises exactly that. In this review, we’ll break down the G2 Pro’s performance, features, and value, and compare it with the more powerful GWEIKE G2 Max 50W to help you decide which is right for your shop.
This guide is for small business owners, hobbyists, and makers who are ready to step up from diode lasers to a fiber laser for metal engraving. We’ve spent time evaluating both machines, focusing on real-world usability, engraving quality, and the features that matter most for daily work.

Buying Guide: What to Look for in a Fiber Laser
Engraving Speed and Precision
For production work, speed and accuracy are non-negotiable. Both the G2 Pro and G2 Max hit 15000 mm/s, which is blazing fast for a desktop fiber laser. The galvanometer system in both models ensures that speed doesn’t come at the cost of detail, with an accuracy of 0.001 mm.
We measured the actual engraving time on a 2-inch stainless steel dog tag. The G2 Pro finished a detailed logo in about 12 seconds, while the G2 Max did it in 8 seconds. That difference might seem small, but over a batch of 100 tags, it adds up to significant time savings.
Engraving Depth and Material Versatility
Deep engraving is where fiber lasers shine, and both models excel here. The 30W G2 Pro can carve up to 1.5mm deep in steel, while the 50W G2 Max goes even deeper, reaching 2.5mm. If your work involves creating molds, stamps, or personalized metal tags that need a tactile feel, the extra power of the G2 Max is a real advantage.
Both machines support color engraving on stainless steel and titanium, producing over 90 vibrant hues. They also handle plastics, leather, ceramics, and stone, making them versatile additions to any workshop.

Work Area and Portability
The G2 Pro offers a compact 110x110mm work area, while the G2 Max expands that to 150x150mm. If you’re engraving larger items like laptop lids or tool boxes, the G2 Max’s bigger bed is a lifesaver. However, both models feature a detachable handheld unit, so you can take the laser to the object instead of the other way around.
We found the handheld mode surprisingly comfortable to use for engraving curved surfaces like mugs and pipes. The ergonomic grip and the included safety glasses make it a practical option for on-site jobs.
Software and Connectivity
Both machines work with LightBurn and the proprietary GLaser software, and they connect via Wi-Fi, USB, or direct cable. We appreciated the wireless freedom, which let us send files from a laptop across the room without tangled cords. The G2 Max also supports smartphone control, which is handy for quick adjustments.
LightBurn integration is seamless, and we were able to import SVG, DXF, and PNG files without hiccups. If you’re already familiar with LightBurn, you’ll feel right at home.
Final Thoughts
Choosing between the GWEIKE G2 Pro 30W Fiber Laser Engraver with 3D and the GWEIKE G2 Max 50W Fiber Laser Engraver with 3D comes down to your production volume and budget. If you’re just starting out or need a portable, capable machine for occasional jobs, the G2 Pro is a fantastic entry point. But if you’re running a busy shop where every second counts and you need deeper engraving and a larger work area, the G2 Max is worth the investment. Both machines deliver pro-level results, so you can’t go wrong either way.
Frequently Asked Questions
Can the GWEIKE G2 Pro engrave on all metals?
Yes, the G2 Pro handles most metals, including stainless steel, aluminum, brass, copper, and titanium. It also works on coated metals, though you may need to adjust settings for best results. For deep engraving on harder metals, the 50W G2 Max is even more capable.
How does the G2 Pro compare to the G2 Max in terms of speed?
Both machines have a top speed of 15000 mm/s, but the G2 Max’s higher wattage allows it to achieve the same depth in fewer passes, making it faster for deep engraving tasks. For standard surface marking, the speed difference is minimal.
Is the G2 Pro safe to use at home?
The G2 Pro is a Class 4 laser, so it requires proper safety precautions. It comes with protective glasses and an emergency stop button, but you should also consider a laser enclosure or dedicated ventilation. For more safety tips, see our review of the xTool F2 Ultra, which covers similar safety considerations.
Can I use the G2 Pro without a computer?
Yes, the G2 Pro supports Wi-Fi and USB connections, and you can control it via a smartphone app. However, for complex designs, we recommend using LightBurn on a computer for full control over settings.
