Why 50W Changes the Fiber Laser Conversation

The G2 series started with 20W and 30W configurations that established Gweike's portable fiber laser approach. The G2 Max is a significant improvement over the original G2 family — it brings the same 50W JPT fiber laser source in a smaller and more compact form, with the main improvement being the electric autofocus capability.

At 50W, the machine enters a different performance category:

Engraving depth: With 50W power, the G2 Max can engrave as deep as 5mm, expanding your creative possibilities. Standard 20W–30W fiber lasers engrave 0.5–1.5mm in comparable pass counts. This opens up dimensional text, relief logos, coin dies, and mold work that lower-wattage machines simply can't achieve.

Color marking: 90+ colors on stainless steel and titanium — a result that requires high enough peak pulse energy to produce controlled thermal oxide layers at specific frequencies and power levels. On a 20W machine, the color range is narrower and less saturated. At 50W, color logos on stainless produce more vivid results — richer greens, deeper blacks, more saturated blues. 

3D carving: The 50W power enables deep engraving, 3D texturing, raised logos, and recessed lettering in metals like brass, copper, and stainless steel — valuable for custom jewelry, coin embossing, and industrial mold marking.

15,000 mm/s Speed — And the Galvo That Delivers It

The rated 15,000 mm/s engraving speed is produced by the industrial-grade fully digital galvo scanning system — not a gantry, not stepper motors, not belts. The galvo redirects the laser beam using high-speed mirrors without physically moving the laser head, which is why galvo fiber lasers produce these speeds without sacrificing precision.

The precision delivered at these speeds: 0.001mm positioning accuracy and 8K HD engraving resolution. Fine serif text at small sizes, intricate circuit-board style patterns on metal, photorealistic grayscale portraits on aluminum — the detail holds at full production speed.

The performance of the G2 Max is hard to beat for users who need deep and precise engravings on metals. The laser's ability to focus tightly ensures clear, detailed designs without blurring.

90+ Colors — What That Actually Means and Why It Matters

Fiber lasers without MOPA source control (standard Q-switched lasers) produce black and white marks on metal — period. Color requires adjustable pulse width and frequency, and the G2 Max's ytterbium fiber source provides that control through the 20–200 kHz frequency range and EZCad/LightBurn parameter settings.

The technical mechanism: varying pulse frequency and power creates different controlled oxide layer thicknesses on stainless steel and titanium surfaces. Different oxide thicknesses refract light differently — producing the visible color. Golds, blues, reds, greens, purples, and gradients between them are all achievable once parameters are dialed in.

Color engraving can make your products stand out in a crowded market. If you're in the business of creating custom items, the G2 Max's color marking capability is a genuine differentiator.

For custom jewelry, branded merchandise, personalized stainless tumblers, and industrial component marking where color adds traceability or aesthetics, this is the capability that increases per-piece price and perceived value.

Electric Autofocus and Dual Red-Light Positioning

Getting the focal distance exactly right between every material change is where less automated fiber lasers cost time. The G2 Max solves this with two features:

Electric Lift Column: The Z-axis adjusts with the push of a button to set the correct focal distance for each material height. No ruler, no manual adjustment, no test burns to confirm focus. Place the material, press the button, start engraving.

Dual Red-Light Positioning: Before the laser fires, two visible red guide lights project onto the material showing exactly where the laser will mark. This allows users to preview the engraving boundaries on the material and adjust placement before committing — ensuring your design lands exactly where you intend it. For irregularly shaped pieces, pre-printed blanks, and precise-placement work, this preview step eliminates misalignment mistakes.

Desktop Machine. Handheld Engraver. Both in One.

The G2 Max's detachable design converts the machine from a desktop engraver to a handheld unit in seconds. Remove it from the base column, reorient it to any angle, and engrave surfaces that can't come to the machine.

The detachable structure extends engraving capabilities beyond traditional workbenches, allowing it to engrave almost anywhere — providing unmatched flexibility and adaptability.

Practical applications: engraving a serial number on a large fabricated part without moving it, marking a vehicle component in place, engraving on the front face of a wall panel, or working at trade shows and markets where bringing the workpiece to a fixed machine isn't practical.

At 6.5kg and 260mm × 440mm × 505mm, the G2 Max is genuinely portable by one person. Available in St. Patrick Blue, Rose Pink, and Gulf Blue — color options that matter for studios where the machine is visible to clients.

Material Range: Metals, Plastics, and More

The G2 Max's 1064nm fiber wavelength is absorbed efficiently by metals and certain non-metals:

Metals (marking, engraving, cutting, color): Stainless steel, aluminum, brass, copper, gold, silver, titanium, and alloys. Deep engraving to 5mm on most metals with appropriate pass counts.

Non-metals (marking and surface engraving): Leather, hard plastics (ABS, PC), dark glass, colored ceramics, acrylic, stone, rubber.

Thin metal cutting: The 50W output enables cutting thin metal sheet — stainless steel, aluminum, and brass in the 0.3–0.8mm range depending on material and parameters.

What the G2 Max does not do: wood, clear acrylic at depth, fabric, or organic non-metals — those require a CO₂ or UV laser. For mixed-material shops, the G2 Max handles the metal work that CO₂ machines can't.

LightBurn Compatible. GLaser Ready. WiFi and USB.

The G2 Max connects via USB and WiFi and is fully compatible with LightBurn galvo mode on Windows and macOS — the same software used across CO₂ and UV laser machines. It works great in LightBurn. For users who already own a LightBurn license for other machines, the G2 Max integrates into the same workflow immediately. 

GLaser (Gweike's proprietary software) is also supported for operators who want a machine-specific environment with preset material libraries. Supported file formats include SVG, DXF, AI, BMP, JPG, PNG, and others.

The machine carries CE and FDA certifications (FDA Accession: 2211667-002) and is equipped with an emergency stop button, protective glasses, and a radiation-filtering protective cover.

Frequently Asked Questions (FAQs) About Gweike G2 Max Fiber Laser:

Q: What's the difference between the G2 Max (50W) and the G2 Pro (30W)?

A: Power and depth are the primary differences. The G2 Max at 50W engraves up to 5mm deep on metal and produces more vivid color results with higher saturation. The G2 Pro at 30W is suited for lighter production work and surface marking with less need for deep engraving depth. Both use the same galvo system and detachable portable design. If deep engraving, coin embossing, or maximum color vibrancy are part of your work, the 50W is worth the step up. If surface marking and moderate depth is the daily workflow, the 30W is a cost-effective choice.

Q: Can it really engrave 5mm deep?

A: With 50W power, the G2 Max can engrave as deep as 5mm on metal. This is achieved through multiple passes with optimized speed, frequency, and power settings — not a single pass. Depth per pass varies by material hardness. Brass and aluminum reach significant depth relatively quickly. Hardened steel requires more passes. For production coin dies, dimensional logos, and mold work, this depth capability is the key differentiator over 20W–30W machines. 

Q: How does color marking work?

A: The fiber laser creates controlled thermal oxide layers of varying thickness on the metal surface by precisely varying pulse frequency and power. Different oxide thicknesses reflect light at different wavelengths, producing visible colors. Specific frequency and power combinations produce specific colors — once parameters are established for a material and color, they're saved and recalled. The G2 Max supports over 90 distinct colors on stainless steel and titanium through the full available frequency and power range.

Q: Can it be used as a handheld engraver?

A: Yes. The machine detaches from its base column and can be held or positioned at any angle for engraving surfaces that can't come to the machine. At 6.5kg, one person carries it comfortably. This is particularly useful for on-site work, large fabricated parts, automotive components, and field marking applications.

Q: What software does it use, and is LightBurn included?

A: The machine is compatible with both GLaser (Gweike's proprietary software, included) and LightBurn galvo mode (requires a LightBurn galvo license, purchased separately from Lightburn). It works great in LightBurn. GLaser provides machine-specific presets and is the recommended starting point. LightBurn is the preferred choice for users who already work in that environment for other machines.

Q: Does it need a water chiller?

A: No. The G2 Max is air-cooled — no water chiller, no plumbing, no coolant management. The < 120W power consumption runs on standard 110–240V household and workshop power. Setup is plug-and-go.

Q: Can I engrave tumblers and cylindrical objects?

A: Yes, with compatible rotary accessories (available as optional add-ons). The G2 Chuck Rotary handles rings, bracelets, and small cylindrical items. The G2 Roller Rotary handles mugs, cups, tumblers, and bottles. Either connects to the machine's rotary port.

Q: What materials can't it mark?

A: Wood, clear acrylic, fabric, leather at production cutting scale, and most organic materials are better suited to CO₂ or UV lasers. The G2 Max's 1064nm fiber wavelength is optimized for metals and specific non-metals (hard plastics, dark glass, ceramics, stone). For a mixed-material shop, the G2 Max handles metal and the CO₂ or UV laser handles everything else.

Q: What's the warranty?

A: 2-year warranty on the machine, 1 year on the laser source. CE and FDA certified.

Q: Why buy from The Maker's Chest instead of directly from Gweike?

A: Our 75-day return window gives you real production evaluation time — more than double Gweike's direct 30-day policy. Our USA-based expert support team is reachable by phone and email and available for parameter guidance, LightBurn and GLaser setup, and production optimization throughout your ownership. If the machine isn't performing as expected after delivery, we're the call that gets it resolved.
