TL;DR
Gweike G2 Pro 30W Fiber is the 30W SKU on the Gweike gweike g2 line. Gweike G2 packages a 20W fiber galvo in a desktop form factor. Verify optical power on the listing: do not assume combined-watt marketing.

What makes this machine stand out
Hardware and workflow features worth understanding before you buy : not just wattage on a label.
A clear depth step over the 20W
Gweike's comparison shows 3.7 mm in brass after two hours at 1,000 mm/s, against 2.1 mm for the 20W. Coins, dog tags with deep text and slate reach the same result in noticeably fewer passes.
Choice of 110 mm or 150 mm field
The Pro is sold with either lens. The 110 mm lens gives a smaller spot for fine text; the 150 mm lens fits more parts per batch. The G2 Max only ships with the 150 mm lens.
Our verdict
Ideal if you
Gweike G2 Pro Fiber 30W fits shops that mark stainless, aluminum, and tools daily without a CO₂ bay. A solid bench option for jewelry, tags, and small batches.
Skip if you
Skip if wood, leather, or cast acrylic pay your bills. Deep metal cutting and large industrial panels often need more fiber headroom (50W) or a different machine class.
Pros
- Two configurations: 110 mm lens with manual lift at $1,599, or 150 mm lens with electric lift at $1,799 (Gweike, Oct 2026)
- About 75% deeper than the 20W in Gweike's two-hour brass test (3.7 mm vs 2.1 mm)
- Cuts 0.5 mm brass in about 7 passes at 10 mm/s, workable for small jewelry blanks
Cons
- Still a Q-switched source: no MOPA pulse control for consistent colours on stainless
- In the 150 mm electric version, the price gap to the G2 Max is only $700
- Millimetre-deep engraving still takes hours, not minutes

Pro tips
Fix parts firmly; start with low power test squares on scrap metal. Rotary adds complexity: budget time to learn indexing.

Common questions
What does the G2 Pro 30W gain over the 20W in practice?
Mostly depth and fewer passes. In Gweike's comparison the 30W reached about 3.7 mm in brass after two hours at 1,000 mm/s (20W: 2.1 mm) and 2.3 mm in slate after one hour (20W: 1.7 mm). It cut 0.5 mm brass in 7 passes at 10 mm/s, against 11 for the 20W. Surface marks look much the same.
How much does the G2 Pro 30W cost compared with the other G2 models?
On Gweike's US store (October 2026) the G2 Pro is $1,599 with the 110 mm lens and manual lift, or $1,799 with the 150 mm lens and electric lift. That is $300 to $450 more than the 20W in the same configuration, and $700 less than the G2 Max, which only comes with the 150 mm lens and electric lift at $2,499.
G2 Pro or G2 Max: which one for a small engraving business?
The Pro suits a business that mostly marks: tumblers, pet tags, knives, business cards, with some deeper engraving now and then. Pick the Max if coins, deep relief or cutting thin brass and silver blanks are weekly jobs: in Gweike's demo it cuts 0.5 mm brass in 4 passes instead of 7.

ComMarker · Fiber · $1,399 – $1,632
The ComMarker B4 is a popular entry-level fiber galvo engraver for jewelry, tools, and metal gifts. Marks stainless, aluminum, and brass without spray. Small marking field: not a cutter for wood or acrylic.
Monport · Fiber · $2,440 – $2,690
Monport GT 30W brings split-cabinet fiber marking with autofocus: useful for varying part heights. Strong alternative to Gweike G6 in the same class.
Sculpfun · Fiber · $1,499
The Sculpfun G20 is a 20W 1064 nm fiber galvo on an open stand, launched in August 2026. It marks and engraves stainless, aluminium, brass, gold and titanium over a 150 × 150 mm field, with a motorized Z column, dual red-dot focusing and Wi-Fi. Sculpfun claims 10,000 mm/s, a 0.01 mm spot, engraving up to 1.5 mm deep and colour marking on stainless and titanium. No independent review yet; the open frame means you handle 1064 nm safety yourself.
