Quick verdict
The Gweike M1200 is an air-cooled 1200W handheld fiber laser welder that also cleans and cuts, and it is the same welder unit Gweike pairs with its M3 CNC bed. It costs $4,899 on Gweike's US store, and the 800W M800 is $3,899. Gweike claims welding from 0.2 to 5 mm, handheld cutting from 0.5 to 3 mm, cleaning up to 20 mm wide and a touchscreen with parameters for more than 100 materials. Handheld cuts are freehand and rough next to a CNC bed, and the open Class 4 beam needs a screened work area, eye protection and a heavy 220V circuit.
What you still need
A dedicated 220V circuit (Gweike's M Series FAQ recommends a 32A breaker for this laser source), argon or nitrogen with a regulator (Gweike also lists air), filler wire on 5 kg spools up to 1.2 mm, spare nozzles and protective lenses, a conductive metal work table for the ground clamp, fume extraction, welding screens or curtains, and wavelength-rated laser goggles and gloves for you and anyone nearbyMaterial reality check
Gweike says it welds stainless steel, aluminum, copper, carbon steel, titanium and more from 0.2 to 5 mm, cuts 0.5 to 3 mm sheet by hand and removes rust, paint and residue up to 20 mm wide per pass. The thickness figures are not split by metal; OMTech's published table for its own handheld (4 mm steel, 2 mm aluminum) is a reminder to test before relying on 5 mm in aluminum or copper. It does not engrave and is not for non-metals. Never process PVC or vinyl.Better alternative if
you need repeatable CNC-cut parts, since the M3 Pro mounts this same 1200W source on an enclosed cutting bed and adds a CO2 laser: Gweike M3 Pro 6-in-1 Laser Welder and CNC CutterScores

Pros and cons
Why we like it
- 1200W welder, cleaner and cutter for $4,899
- Air cooled, so there is no chiller to fill or drain
- Gweike publishes a handheld cutting range of 0.5 to 3 mm and welding from 0.2 to 5 mm
- Up to 20 mm cleaning width and a touchscreen with presets for over 100 materials
- The same 620 x 355 x 610 mm welder unit is the laser source in Gweike's M3 CNC system
Watch out for
- Freehand cuts up to 3 mm, not repeatable parts like a CNC bed
- Open Class 4 beam, and eye protection is not clearly included
- Gweike does not split welding or cutting figures by metal
- Warranty, power supply and package contents are not spelled out on the welder's own page
- About 60 kg with the wire feeder, and no independent reviews yet
