Quick verdict
The Gweike M3 Ultra is the big version of the M3: the same 1200W fiber laser welder, whose source and head also mount on an enclosed CNC cutting bed, but with a 1380 x 920 mm bed, a 130W CO2 laser for non-metals and a faster 800 mm/s gantry. At $13,999 on Gweike's US store it costs $2,500 more than the M3 Pro for more than three times the bed area, and about $2,000 less than the xTool MetalFab welder and cutter, whose bed is 610 x 610 mm. Gweike claims CNC cuts up to 10 mm in metal and 25 mm with the CO2 laser, handheld welding from 0.2 to 5 mm and ±0.02 mm repeatability. It is a 610 kg shop machine that needs a forklift, a hard-wired 220V supply and bottled nitrogen and oxygen, and Gweike publishes less cutting and safety detail than xTool does.
What you still need
A forklift for unloading, a door wide enough for a 1780 mm deep machine, and floor space: Gweike's manual asks for at least 1 m of clearance on every side. We run our M3 Ultra with about 20 cm to the walls; what you really need is room to open the door, feed sheet front and back and reach the service panels; an electrician to hard-wire 210 to 240V single phase (the FAQ says about 5 kW with a 32A breaker for the laser and 16A for the bed, the manual asks for at least 63A total, two switches of at least 30A and 6 sq mm cable); nitrogen at 2.0 MPa and oxygen at 0.8 MPa with regulators, or a compressor for thin stainless and aluminum; 7 L of distilled water (plus antifreeze in winter) for the CO2 chiller; sand, gravel or firebricks for the slag cart; ducting for the exhaust fan; a Windows PC; filler wire; goggles and gloves (the manual lists them as buyer supplied); and screens for handheld weldingMaterial reality check
Gweike's material chart lists stainless steel, carbon steel, alloy steel, aluminum, copper, brass, bronze, titanium, silver, and zinc and magnesium alloys for fiber cutting, welding and cleaning, with a 10 mm CNC cut figure that is not tied to a metal. Its FAQ recommends oxygen for carbon steel, nitrogen for stainless over 4 mm and compressed air for thinner stainless and aluminum. The 130W CO2 laser cuts wood, acrylic, MDF, leather, fabric and paper, with up to 25 mm cutting claimed. Never process PVC or vinyl.Better alternative if

Pros and cons
Why we like it
- One 1200W fiber source welds, cleans, cuts by hand and drives an enclosed 1380 x 920 mm CNC bed
- A 130W CO2 laser in the same bed cuts wood and acrylic, which the xTool MetalFab does not offer
- $13,999 is about $2,000 less than the xTool MetalFab welder and cutter, with more than three times its bed area
- Faster gantry than the M3 Pro: 800 mm/s and 1G acceleration against 600 mm/s and 0.6G (maker claims)
- 2-year machine warranty, 1 year on the laser source and CO2 tube
Watch out for
- 610 kg and 2185 x 1780 mm: it arrives by truck and needs a forklift and a wide door
- Hard-wired 220V with conflicting figures: about 5 kW on 32A and 16A breakers in the FAQ, at least 63A total in the manual
- Gweike does not say which metal the 10 mm figure is for, and publishes no window rating, camera or software name
- Handheld welding is an open Class 4 beam, and eye protection is not clearly included
