Xlaserlab X1 Pro vs Gweike 800W: Which Laser Welder Fits?
Short answer: Choose the Xlaserlab X1 Pro when portability, a clearly defined wire-feeder bundle and a well-documented thin-gauge workflow matter most. Choose the Gweike 800W when the additional published power and thickness headroom justify a machine that is more than twice as heavy—and only after confirming the exact North American electrical specification, wire-feeder package and duty expectations. The 100W difference is real, but it is not the whole buying decision.
Research note: This guide uses current manufacturer-published specifications and the configurations sold by The Maker’s Chest as of September 2026. Speed, lifespan, thickness, resolution and output claims are manufacturer ratings, not independent TMC laboratory results. Real performance depends on material, optics, settings, cooling, fit-up, exhaust and job geometry.

Why 800W Does Not Automatically Win
An extra 100W provides more energy and potentially a wider process window, especially near the upper thickness limit. But weld quality also depends on alloy, joint design, fit-up, travel speed, focus, wobble width, shielding gas, wire position and operator consistency. Manufacturer thickness ranges are not standardized test results and should not be read as a promise that every 4 mm Gweike weld will be production-ready while every X1 Pro weld stops at 3 mm.
A machine should be sized around the majority of paid work, not the thickest coupon shown in a demonstration. If most jobs are 0.8–2 mm stainless, mild steel or aluminum, portability and setup may matter more than the last 100W. If the shop repeatedly works near 3–4 mm, validate penetration and duty cycle on the exact joint before deciding.
Portability Is the Largest Practical Difference
The X1 Pro is listed around 21 kg. The Gweike 800W listing states about 49.2 kg for the machine and separately references a 10.8 kg wire feeder. Even before gas, cables and consumables, those are different mobility classes. The X1 Pro can reasonably move between benches or into a service workflow; the Gweike is better treated as a compact stationary system that can be relocated, not carried casually.
Portability also includes electrical and gas logistics. A light chassis does not make the complete welding cell light once the cylinder, regulator, feeder, extraction and laser-control barriers are included.
Wire Feed and Joint Fit-Up
Xlaserlab’s current TMC listing separates a Single Wire Bundle from a Dual Wire Bundle. The dual feeder increases filler delivery and gap-bridging flexibility; it does not increase laser power or the machine’s thickness rating. Most tight-fitting sheet and tube work will not automatically improve with two wires.
The Gweike listing refers to a separate wire feeder but does not provide the same package-level clarity in the current product copy. Confirm whether the feeder, rollers, feed tubes and nozzles for the intended wire diameter are included before comparing total price. An apparently cheaper system can become more expensive once the required filler-delivery hardware is added.
Electrical Requirements Need Written Confirmation
This is an area where generic manufacturer marketing and the current North American retail configuration do not align cleanly. Xlaserlab broadly advertises 100–240V capability, while the current TMC X1 Pro listing instructs U.S. buyers to plan for the supplied NEMA 6-50 connection and a properly installed 240V circuit, typically 50A. For purchase planning, follow the exact shipped configuration and get the electrical requirement in writing.
The current Gweike 800W product copy does not state a complete North American circuit requirement. Do not assume that “air-cooled” means standard household power. Ask for the nameplate input, plug, breaker, conductor and phase requirements before ordering either machine, and have a qualified electrician confirm the installation.
Welding, Cleaning and Cutting
Welding
Both are primarily welding systems. Their strongest economic case is fast, low-distortion joining of suitable thin stainless, mild steel and aluminum with good fit-up. Presets reduce the starting difficulty but do not replace procedure development or destructive validation where joint strength matters.
Cleaning
Localized rust removal and pre-/post-weld cleaning can streamline repair work. Cleaning paint, galvanized coatings or unknown residues can create hazardous fumes, and a narrow welding optic is not the same as a dedicated wide-area production cleaner.
Cutting
Handheld cutting is a supporting function for trimming and field adjustments. It is not a substitute for a guarded CNC cutting table, and freehand cut quality depends heavily on operator control. A buyer whose main goal is cutting should select a cutting system rather than allowing “3-in-1” language to drive the purchase.
Safety Is the Same Class of Problem
Both systems are Class 4 near-infrared fiber lasers. The beam is invisible, and reflections from metal can injure eyes or skin well beyond the immediate weld. Safe use requires wavelength-rated protection, a controlled area, access restriction, reflection management, fire precautions, suitable protective clothing, source-capture ventilation and trained operators. Conventional welding curtains and ordinary shade helmets should not be assumed to control the laser wavelength.
Which One Fits Which Shop?
| Shop profile | Better starting point | Reason |
|---|---|---|
| Mobile repair or work shared across benches | X1 Pro | Much lower published machine weight and a clearer portable workflow. |
| Automotive panels, exhaust and thin fabrication | X1 Pro | Its 700W range aligns with thin-gauge work where distortion control matters. |
| Repeated 3–4 mm work | Gweike 800W, after sample validation | More published power and thickness headroom, but claims need joint-specific proof. |
| Wider gaps and variable fit-up | X1 Pro Dual Wire or verified Gweike feeder package | Filler delivery may matter more than the 100W difference. |
| Fixed fabrication cell | Either | Choose using validated cycle time, electrical service, feeder configuration and support. |
| Primary need is production cutting or wide-area cleaning | Neither by default | A dedicated machine is usually the more appropriate platform. |
Our Recommendation
Choose the Xlaserlab X1 Pro when the work is mainly thin metal and the business benefits from moving the system, using a clearly specified wire-feed package and accessing an established set of presets and accessories. For most buyers, the Single Wire Bundle is the logical start; Dual Wire should be tied to real joint geometry.
Choose the Gweike 800W when it will live in a more permanent cell and the extra 100W can be validated against recurring thicker work. Before ordering, obtain written confirmation of electrical requirements, included feeder hardware, gas setup, duty cycle and application-specific thickness results.
Frequently Asked Questions
Is 800W noticeably stronger than 700W?
It provides additional power and potential process margin, but the practical difference depends on joint, alloy, speed, focus, gas and settings.
Can the Gweike reliably weld 4 mm metal?
The current listing publishes up to 4 mm for the 800W configuration. Treat that as a manufacturer rating and validate your exact joint before sizing production around it.
Can the X1 Pro weld 3 mm metal?
The published range extends to approximately 3 mm, material and process dependent. Routine work at the upper limit should be tested rather than assumed.
Which is easier to move?
The X1 Pro. Its listed machine weight is roughly 21 kg versus about 49.2 kg for the Gweike unit.
Do both use air cooling?
Yes, according to the current product listings.
Does the X1 Pro run on a normal 120V outlet?
Do not assume so. The current TMC U.S. configuration calls for a NEMA 6-50 connection and a properly installed 240V circuit, typically 50A. Confirm the shipped unit.
What power does the Gweike require?
The current product copy does not provide enough North American installation detail. Obtain written nameplate and circuit requirements before purchase.
Is dual wire always better?
No. It helps with greater filler deposition and some wider joints, but it does not increase laser output and adds setup variables.
Can both weld aluminum?
Both list aluminum, but aluminum is reflective and heat-conductive. Validate alloy, thickness, oxide preparation, focus and gas on matching scrap.
Can either replace a CNC laser cutter?
No. Their handheld cutting mode is for limited trimming and adjustments, not guarded, repeatable CNC production.
Are ordinary welding helmets enough?
No. Protection must be rated for the fiber-laser wavelength and form part of a complete Class 4 control plan.
What should I send for a pre-sale recommendation?
Provide metal and alloy, thickness range, joint type, gap tolerance, batch size, daily duty, need for portability, available electrical service and photos or sample drawings.
