CutAir vs xTool MetalFab vs Gweike M Series vs HeroLaser E700: A Practical Comparison for Small Workshops

Compact metal laser cutters are no longer just scaled-down industrial machines. The newest systems are trying to solve different workshop problems: easier setup, smaller footprints, mixed-material cutting, welding, cleaning, marking, and lower entry cost.

This comparison looks at four compact metalworking systems: SF-CutAir, xTool MetalFab, Gweike M Series, and HeroLaser E700. The goal is not to declare one machine better for everyone. The better question is: which system fits your material thickness, workspace, workflow, and budget?

Fact-check note: prices and specifications were checked against public product pages and support documents on May 29, 2026. Additional hands-on review observations for Gweike M Series and the Alleria DIY references were incorporated on June 2, 2026. Always confirm the final configuration, shipping, accessories, and local electrical requirements before purchase.

Quick Summary

What CutAir Is Designed To Do

SF-CutAir is built around a different philosophy from many all-in-one compact systems. Instead of treating the cutter as an attachment to a handheld welder, CutAir is positioned as a dedicated cutting machine for small workshops, studios, and makers who still want industrial-style motion and assist-gas control.

Our view is simple: for repeatable production, a dedicated machine is usually the more stable path. It is similar to the difference between a dedicated game console and a multi-game novelty device. The all-in-one idea sounds flexible, but the most consistent experience often comes when the hardware, controls, cooling, and software are designed around one primary job. For CutAir, that primary job is cutting.

This is why we position CutAir as a semi-industrial machine rather than a purely home-hobby product. It is still compact enough for a small workshop, but the target user is someone who wants to make parts repeatedly, run small batches, test real materials, and build a more production-oriented workflow.

The current 1200W CutAir configuration supports 2ft x 2ft, 4ft x 2ft, and 4ft x 4ft formats. It uses an air-cooled fiber laser platform, a smart touch-screen control system, USB/network import, and a dual-drive linear motion system. The public product page lists 0.6G acceleration, +/-0.1 mm cutting precision, single-phase 220V 50/60Hz input, and a 2ft x 2ft machine size of 1390 x 1190 x 1520 mm.

The most important correction for technical accuracy is cutting thickness. For public comparison, it is safer to describe CutAir as capable of cutting carbon steel up to 10 mm and stainless steel up to 5 mm, based on the linked 1200W cutting parameter table. The product page also mentions 10 mm cutting power for carbon steel, while the parameter table gives more detailed material-specific values.

How To Understand The Market Levels

One useful way to understand this category is to separate machine levels instead of treating every compact laser as a direct competitor. Traditional industrial sheet-metal cutters sit at the top for heavy production. CutAir is positioned below that as a semi-industrial small-workshop machine. Gweike and xTool-style systems are more integrated and beginner-friendly, while ultra-compact systems such as HeroLaser E700 focus on thin materials and very small workspaces.

This does not mean one category is "good" and another is "bad." It means the buyer should first decide what type of work they are actually trying to do: first-time learning, guided maker projects, light fabrication, or repeatable small-batch production. CutAir is built for the last two more than for casual experimentation.

Why CutAir Is Priced Differently

On upfront price alone, CutAir may look more expensive than xTool MetalFab, Gweike M Series, or HeroLaser E700. The important context is that these machines are not aimed at the exact same level of use. Many compact integrated systems are designed as entry-level or guided machines for learning, home projects, and light fabrication. CutAir is built as a more professional small-format production cutter for users who want to make real parts repeatedly.

That is why the value comparison should not stop at the purchase price. For production work, buyers should also consider cutting stability, work-area options, repeatability, assist-gas control, table durability, service access, and how much time the machine can spend making parts instead of being tuned, cleaned, or reconfigured. If the goal is to experiment at home, a lower-cost entry machine can be the right choice. If the goal is small-batch production, a dedicated cutting platform can justify a higher price because it is designed around output, not only convenience.

Hands-On Video References

For a more practical look beyond specification tables, Travis Mitchell from the @diyfiberlaser channel has published hands-on videos for both CutAir and Gweike's compact machine direction. These videos are useful because they show setup details, workflow impressions, and real cutting context rather than only brochure specifications.

Where CutAir Stands Out

• Dedicated cutting layout: CutAir is not just a handheld welding source placed on a bed. Its frame, motion system, cutting head, controls, and assist-air workflow are arranged around CNC cutting for more repeatable semi-industrial use.
• Dual material direction: The 1200W version is described as using fiber plus blue laser modes, giving it a broader material path than metal-only desktop fiber systems.
• Flexible delivery: Buyers can choose DIY assembly or a completed machine, which matters for cost, learning, and service expectations.
• Optional AirFamily workflow: Users who also need welding and marking can add WeldAir and MarkAir, while keeping each machine specialized instead of forcing every task through one head.
• Workshop support path: Small Laser lists Los Angeles test-cut support, remote sample cutting, and batch shipping to the LA warehouse for selected products.

xTool MetalFab: Strong Software and Ecosystem

xTool MetalFab is one of the most polished compact metalworking systems currently on the market. The CNC cutter has a 610 x 610 mm internal working area and is designed to work with the MetalFab laser welder. xTool's support documentation is clear that the CNC cutter cannot operate without the welder, because the welder supplies the laser while the CNC cutter controls the motion.

For users who want software guidance, camera-assisted workflow, nesting, parameter presets, and a mature support experience, xTool is a serious option. Its 1200W Welder + Cutter package is publicly listed at $15,999, and the 1200W All-in-one Bundle is listed at $18,249.

Technically, xTool documents stainless steel cutting in the 2-5 mm range, aluminum in the 2-4 mm range, brass in the 2-3 mm range, and carbon steel or galvanized sheet up to 10 mm with oxygen. For thicker carbon steel, the support guide specifies oxygen, a double-layer nozzle, and a focus extension tube, so buyers should factor in gas setup and accessories rather than looking only at laser wattage.

Gweike M Series: Integrated and Home-Friendly

The Gweike M Series takes a different path from CutAir. The smaller M2 platform offers a 620 x 620 mm working area, while larger MAX and ULTRA variants reach 1,380 x 920 mm. Gweike lists repeat positioning accuracy of +/-0.02 mm, acceleration up to 0.6G on smaller platforms and 1G on larger ones, and power input of 200-240V AC.

The biggest advantage of the M Series is its integrated concept. It brings metal cutting, non-metal CO2 cutting or engraving on selected M3 models, and optional tube-cutting capability into a compact platform. The tube fixture is also installed as a separate base, which is a smart space-saving direction for users who want laser capability at home rather than in a full fabrication shop.

The M3 models add CO2 laser capability, which is useful for users who want metal cutting plus CO2 cutting and engraving in one system. Public pricing currently ranges from $9,999 to $13,999 for the active M2/M3 variants. The tradeoff is that buyers should evaluate process control, consumables, and fixture precision according to the jobs they actually plan to run.

1. Piercing Focus on Thicker Carbon Steel

For thicker carbon steel, piercing and cutting do not always want the same focus strategy. In many oxygen-assisted carbon-steel workflows, piercing is easier to control with a negative focus, while the cutting pass may use a positive focus. If a compact machine uses a fixed-focus cutting head or cannot change focus behavior between piercing and cutting, 5 mm carbon steel can become harder to tune cleanly. This does not mean the machine cannot cut useful work; it means buyers who expect thicker carbon-steel jobs should ask to see the exact piercing and cutting recipe, not only the maximum thickness claim.

2. CO2 Optics Are Useful, But They Are Consumables

The CO2 option is one of the most attractive parts of the M3 direction because it opens the door to acrylic, wood, leather, and other non-metal work. At the same time, a CO2 focusing lens, commonly a ZnSe lens, is a real maintenance item. Smoke, debris, thermal stress, and poor cleaning can shorten lens life. In many service contexts, a replacement focusing lens can be around $30 each, so buyers should include spare lenses, cleaning habits, and expected downtime in the ownership cost rather than treating the CO2 module as maintenance-free.

3. Tube Cutting Needs Its Own Accuracy Check

The optional tube fixture expands what the M Series can do, especially for decorative tube projects and light fabrication. For functional tube parts, buyers should look closely at rotary-axis precision. Round holes can become slightly oval or offset if the tube is not clamped concentrically, if the rotary axis has backlash, if the diameter parameter is wrong, or if the tube shifts during cutting. The cutoff end may also need inspection if the design requires a clean closed profile. The practical advice is simple: if tube cutting matters, ask for a demo using your tube diameter, wall thickness, hole pattern, and cutoff requirement.

4. Cutting Table and Lower Protection Matter

Fiber laser cutting is tough on the worktable. Thin support slats can wear quickly, collect dross, and lose flatness after repeated exposure to the beam and hot metal slag. If the lower layer is open or not protected with fire-resistant material, the buyer should also evaluate spark control, cleaning access, and what sits below the cutting path. For any compact fiber cutter, it is worth asking whether the slats are easy to replace, whether there is a protected lower tray or fire-resistant layer, and how the machine is cleaned after regular metal cutting.

These points do not remove the appeal of Gweike's design. They simply define the right buyer profile. The M Series is interesting for users who value a compact, modern, multi-material workstation. CutAir is more focused on dedicated metal cutting capacity, repeatability, and small-batch workshop use.

HeroLaser E700: The Compact Specialist

HeroLaser E700 takes the opposite approach from larger workshop systems. Its public product page describes a compact 700W two-machine package: C700 for desktop metal cutting and engraving, plus T700Pro for welding, cutting, and cleaning. The stated working area is 400 x 300 x 40 mm, and the product page says the system weighs about 50 kg.

The public cutting claims are also smaller in scope: up to 3 mm stainless steel and carbon steel, up to 2 mm aluminum, and up to 1.5 mm copper or brass. That makes E700 interesting for jewelry, small parts, thin sheet, and extremely space-constrained workshops. It is not trying to compete with the larger 1200W cutting beds on cutting envelope or thick-sheet capability.

How To Choose

Choose CutAir if you want a dedicated 1200W cutting platform for semi-industrial small-batch production, need 2ft x 2ft or larger formats, want metal plus selected non-metal capability, and like the option of DIY assembly or adding separate welding and marking machines later.

Choose xTool MetalFab if software experience, guided workflow, camera support, and maker-friendly ecosystem matter more than maximizing work area or keeping cutting separate from welding.

Choose Gweike M Series if you want an integrated, beginner-friendly system with camera support, a lifting table, larger format options, optional CO2 capability, and occasional tube-cutting flexibility, and your work is mainly light fabrication, learning, home workshop use, or mixed creative projects rather than thick-sheet production.

Choose HeroLaser E700 if compact size is the top priority and your projects are mostly thin sheet, jewelry, small signage, or small custom metal parts.

Simple Buying Direction

Two DIY Routes Beyond Finished Machines

DIY Path 1: Lower-Budget Small-Format Metal Laser Cutter

The first DIY option is worth mentioning because Sky Fire also started from the DIY fiber laser community. If you mainly want to learn, experiment, and build your own compact metal laser cutter, a DIY route can cost less than buying a finished xTool, Gweike, or HeroLaser-style compact system. The tradeoff is that you become the integrator: you need to understand the laser source, motion system, control board, electrical safety, enclosure, assist gas, and cutting parameters.

For technically curious users, that tradeoff can be part of the fun. You can keep the footprint small, choose your own components, and learn how the machine really works. For business users who need repeatable output right away, CutAir is the more direct production path. For builders who want the lowest-cost hands-on learning path, see this Sky Fire guide: DIY Small-Format Metal Laser Cutter: Compact & Efficient.

Linked DIY Component Price Breakdown

Prices below were checked from the linked Alleria Store product pages on June 2, 2026. They are component prices, not a complete ready-to-run machine price. Raycus and Maxphotonics are listed as alternative fiber laser source brands, not as separate machine categories. Frame, enclosure, worktable, wiring, electrical cabinet, air compressor, shipping, tax, duties, labor, and local safety compliance may still need to be budgeted separately.

Using the lowest linked Raycus 800W pure-fiber core example, even after adding the NNT gas module, K2 smoke purifier, and the low-cost linked consumables set, the listed component subtotal is about $4,537.57 before the unlisted mechanical structure, enclosure, electrical cabinet, air compressor, shipping, tax, and labor. That is why the DIY path can sit far below finished compact machines in upfront cost, while still requiring more technical work from the builder.

DIY Path 2: WeldAir + Cobot Conversion

A second DIY direction is not a cutter build at all, but a way to turn a handheld laser welder into a robot-guided process tool. In the WeldAir Cobot DIY guide, a WeldAir handheld laser welding head is mounted to the end of a collaborative robot, then the basic process signals are connected so the robot can repeat a taught welding or light cutting path.

This is useful for a different buyer than a dedicated cutting machine. A handheld laser welder is flexible, but the final weld still depends on operator angle, travel speed, hand stability, posture, and fatigue. A cobot conversion keeps the familiar handheld welding system for laser output, gas, wire feeding, and welding control, while the collaborative robot provides the repeatable motion.

Linked WeldAir + Cobot Component Price Breakdown

Prices below were checked from linked Alleria Store product pages on June 2, 2026. They are component references, not a finished robot welding cell quote. Custom mounting brackets, robot flange adapters, fixtures, I/O wiring, signal conversion, laser shielding, interlocks, commissioning, shipping, tax, duties, and local safety compliance may need to be budgeted separately.

The core cobot conversion work is mechanical mounting, signal matching, path teaching, and process tuning. Buyers should check robot payload and wrist torque, bracket weight, cable routing, fiber and gas line protection, laser/gas/wire sequencing, fume extraction, interlocks, PPE, emergency stop, and local laser safety requirements before trying this type of build.

Final Takeaway

The compact metal laser market is splitting into clear categories. xTool is strong in software and workflow. Gweike is strong in integrated features, home-friendly packaging, and multi-material flexibility. HeroLaser is focused on ultra-compact thin-metal work. CutAir's advantage is its dedicated cutting-machine approach: it keeps the cutter focused on cutting for more stable small-batch production, while still allowing a broader AirFamily workflow through separate WeldAir and MarkAir machines.

The DIY routes are useful context, but they should be read as learning and exploration paths rather than direct substitutes for every finished machine. A DIY small-format cutter can lower the entry cost for hands-on builders. A WeldAir + cobot conversion can give handheld laser users a way to explore repeatable robot-guided welding and light cutting. CutAir remains the more direct choice when the job is repeatable flat-sheet cutting and small-batch part production.

For buyers, the smartest next step is not only comparing wattage. Ask for a test cut using your own material, confirm assist-gas requirements, check piercing and focus control, inspect tube-cutting samples if you need rotary work, and make sure the worktable and lower protection match the kind of cutting you plan to do.
