xTool MetalFab 800W vs. 1200W

Same Machine, Different Capabilities — Here's What Changes

The xTool MetalFab is unusual in the laser welding market: it's a fully integrated welding and CNC cutting platform, not just a handheld welder. Both the 800W and 1200W share the same physical CNC cutting table, the same dual 16MP camera system with AI smart nesting, the same XCS software with 100+ preset parameters, and the same 550g detachable laser torch form factor.

The differences are more targeted than the wattage gap suggests. It's not a question of whether one is "better" — it's whether your specific application needs hit the 800W's ceilings.

Understanding those ceilings requires specific numbers, not generalizations. This comparison provides both.

xTool MetalFab 800W: Specs and Strengths

Weld Depth and Material Capability

Confirmed from xTool's published specifications:

• Laser power: 800W
• Maximum weld depth (stainless steel / carbon steel): 4mm
• Maximum weld depth (brass / aluminum): 3mm
• Minimum weld thickness: 0.2mm (thin sheet capability)
• Wire feeder: Built-in wire feeding mechanism (lightweight, in the torch)

Materials: stainless steel, aluminum, brass, carbon steel, galvanized sheet, titanium, nickel alloy, magnesium. The material list is comprehensive — the 800W limitation is depth on specific materials, not material type.

The 4mm stainless/carbon steel ceiling covers: most automotive bodywork (0.8–2mm panels), standard sheet metal fabrication (1–3mm), light structural brackets (2–4mm), and most small shop fabrication work up to that depth. Below 3mm — which represents the majority of real sheet metal and light fabrication work — the 800W is fully adequate.

---

Cutting Capability

The xTool MetalFab's laser head is detachable and converts between welding, handheld cutting, and cleaning modes. For the 800W:

• Handheld cutting (stainless steel / carbon steel): up to 3mm
• CNC cutting (with the MetalFab CNC table): carbon steel up to 8mm, stainless steel up to 3mm at quality cut; thicker gauges possible at reduced quality

The CNC table cutting capability is partially independent of the welding wattage because the cutting head and CNC system have their own optimisation — but the welding torch power does influence what the CNC cutting head can achieve. The 800W CNC table cuts 8mm carbon steel; the 1200W CNC table cuts 10mm carbon steel.

---

Power Requirements and Workshop CompatibilityThis

The 800W model requires a circuit of 15A or higher, with a maximum power output of 3000W. In the US, this means a dedicated 220V/15A circuit — a less invasive electrical requirement than the 1200W's 21A circuit. Many workshops with existing 220V tool circuits (welder outlet, air compressor) may already have 15A 220V available or can add it more easily.

Power input: 200–240V. Standard for professional workshop tools — not standard household 110V, but a common shop circuit voltage.

Weight and Portability

The welding torch (the handheld component): 550g with 5-second quick-release for mode swapping. The CNC table (the stationary component): 150kg, 46.26 × 45.55 × 48.43 inches. The CNC table is not portable and requires shop installation regardless of which power model you choose. The welding torch is handheld and portable.

xTool MetalFab 1200W: What the Extra Power Delivers

Weld Depth Gains

The 1200W model's published specifications:

• Laser power: 1200W
• Maximum weld depth (stainless steel / carbon steel): 5mm
• Maximum weld depth (galvanized sheet): 5mm
• Maximum weld depth (brass / aluminum): 4mm
• Minimum weld thickness: 0.2mm (same as 800W)

The 1mm improvement on steel/stainless (4mm → 5mm) is the primary welding capability gain. For shops whose regular work stays under 4mm, this extra millimetre is unused headroom. For shops regularly welding 4–5mm structural components — thicker brackets, tube wall sections, frame elements — the 1200W's ceiling provides the required coverage.

The 1mm improvement on brass/aluminum (3mm → 4mm) is more meaningful for shops working with these materials, which are more challenging to weld due to high thermal conductivity. The 1200W's additional power improves the process window on these metals.

---

Cutting Capability Upgrade

With the 1200W model:

• Handheld cutting (stainless steel / carbon steel): up to 5mm
• CNC cutting (carbon steel): up to 10mm in a single pass
• CNC cutting (stainless steel): improved capability

The CNC cutting upgrade from 8mm to 10mm carbon steel is the more significant capability jump for shops doing production part cutting. 10mm carbon steel represents genuinely thick structural material — brackets, plate components, structural panels. For a fabrication shop doing CNC production cutting, this is where the 1200W makes its clearest case.

---

Wire Feeder and Additional Accessories

This is where the 1200W package differs most visibly from the 800W: the 1200W welder includes a free wire feeder (the xTool Wire Feeder), while the 800W has a built-in wire feeding mechanism in the torch that is lighter and more compact.

The 1200W wire feeder adds:

• Gap bridging capability for joints with fit-up variance
• Fillet weld material addition for stronger joints
• Access to thicker weld beads for build-up and repair applications
• Standard wire diameters: 0.8mm and 1.0mm, stainless and carbon steel

For fabricators who bridge gaps, build up material, or do filler-assisted welds as part of regular work: the included wire feeder on the 1200W is a meaningful value addition.

---

Power Requirements

The 1200W model requires a circuit of 21A or higher, with a maximum power output of up to 4200W. This requires a dedicated 220V/21A circuit — equivalent to a large residential electric range or high-current workshop welder outlet. If your shop doesn't already have a 21A 220V circuit, budget $300–$800 for electrical installation (depending on distance from the panel and whether a new breaker is needed).

Input voltage: 200–240V. The same voltage range as the 800W; the difference is the required amperage.

---

Head-to-Head: 800W vs. 1200W

For Welding

On material under 3mm: both machines produce equivalent weld results. The XR laser series' shared parameters and beam characteristics mean that thin sheet performance is not meaningfully differentiated by the 400W power gap on thin material.

On material 3–4mm: the 1200W is more comfortable; the 800W can weld 4mm stainless but is closer to its ceiling.

On material 4–5mm: 1200W only. The 800W cannot achieve reliable single-pass welds at this thickness.

---

For Cutting

For CNC precision cutting of design-file parts: both machines use the same VibeFreeCut™, FlexiTrack™, ObstacleFree™ system at 400mm/s and 0.1mm precision. The quality of precision cutting from the CNC table is equivalent between models for material within both machines' capability range.

For cutting above 8mm carbon steel: 1200W only.

For handheld cutting above 3mm: 1200W only.

---

For Cleaning

The laser cleaning function (rust removal, pre-weld preparation, post-weld cleaning) uses the same MaxClean accessory across both models. Cleaning mode performance is not meaningfully differentiated between 800W and 1200W — the cleaning process uses specific cleaning nozzles and lower power settings optimised for surface work rather than the full welding power.

The MaxClean accessory achieves 3× wider rust/paint removal width than standard cleaning modes — this performance applies equally to both models.

Price Difference and ROI

xTool MetalFab Kickstarter pricing (campaign currently active at time of writing):

• 800W welder only: $4,999
• 800W + CNC table: $7,999 (Kickstarter); MSRP $10,999
• 1200W + CNC table (standard): $11,999 (Kickstarter); MSRP $14,999
• 1200W + CNC table (extended bundle): $13,999 (Kickstarter)

The full system price gap between 800W and 1200W with CNC table: approximately $3,000–$4,000 at Kickstarter pricing, rising to approximately $4,000 at MSRP.

For the complete pricing framework across the xTool MetalFab and how it compares to other laser welding systems at equivalent price points, our how much does a laser welder cost guide covers the full market.

ROI question: Does the 1200W's additional welding depth (1mm), CNC cutting depth (2mm), and included wire feeder justify $3,000–$4,000 more?

If any of the following are true, yes:

• You regularly weld or cut material in the 4–5mm range for welding, or 8–10mm for CNC cutting
• You use wire feeder capability for gap bridging or filler work and would otherwise purchase the accessory separately
• Your primary CNC production cutting involves carbon steel above 8mm

If none of these apply to your regular work: the 800W provides equivalent performance at lower cost and lower electrical infrastructure requirement.

For the broader question of whether any multi-function laser welding system is worth the integrated-system investment over separate tools, our 3-in-1 laser welder worth it guide covers the all-in-one value proposition in detail.

Who Should Buy the 800W?

The MetalFab 800W is the right choice for:

Standard sheet metal fabrication shops whose regular work stays under 3mm. Automotive bodywork, light structural brackets, metal art, signage fabrication, enclosure work — all under 4mm where the 800W covers the application with margin.

Shops doing production CNC cutting under 8mm carbon steel or under 3mm stainless. The 800W CNC table handles these specifications, and the AI smart nesting and dual 16MP camera system deliver the same production cutting efficiency as the 1200W on material within range.

Workshops with existing 220V/15A circuits — the 800W's lower amperage requirement may allow installation on an existing circuit without electrician upgrades.

Buyers optimising total system cost — the $3,000–$4,000 savings over the 1200W is real money, and for a shop whose material range is under 3–4mm welding and under 8mm CNC cutting, the 800W provides full coverage.

Who Should Buy the 1200W?

The MetalFab 1200W is the right choice for:

Shops regularly welding 4–5mm steel or stainless — structural brackets, heavier tube, thicker plate work. If this material range appears in your shop weekly, the 1200W's ceiling provides the required coverage.

Production CNC cutting shops working with 8–10mm carbon steel — the 1200W's CNC cutting depth handles thicker structural plate that the 800W can't clean-cut. For shops whose production parts frequently involve 8–10mm carbon steel plate, this is the governing specification.

Fabricators who need wire feeder capability — the free included wire feeder on the 1200W (versus the built-in compact mechanism on the 800W) provides gap bridging and filler-assisted welding that repair shops and structural fabricators use regularly.

Shops already running 220V/21A circuits — the higher electrical requirement is a barrier only if you don't already have it. Many professional welding shops have 220V/21A or 30A circuits already for TIG or MIG welders; the MetalFab 1200W can replace those on the same circuit.

Higher-volume production operations where the maximum capability headroom is commercially valuable — consistently working near the 800W's ceiling creates quality risk; the 1200W's additional power provides margin.

Verdict

Both MetalFab models represent the same fundamental product: a first-of-kind integrated laser welding and CNC cutting system with AI smart nesting, dual cameras, and multi-function capability. The platform is identical; the capability difference is specific.

Choose the 800W if: your regular work is under 4mm steel/stainless, under 8mm CNC carbon steel cutting, and you don't need the external wire feeder for filler work. The 800W covers this range completely and saves $3,000–$4,000 upfront with a lower electrical infrastructure requirement.

Choose the 1200W if: you regularly weld 4–5mm material, need CNC cutting above 8mm carbon steel, or rely on wire feeder capability for your fabrication work. The free wire feeder alone may justify a portion of the price gap for shops that would otherwise purchase it separately.

One practical note: the MetalFab is still a relatively new product (launched on Kickstarter mid-2025). Long-term reliability data doesn't yet exist in the way it does for established brands. xTool provides CE, FCC, and FDA certification, a US support team, and demo room access — useful signals for a significant capital equipment purchase.

Frequently Asked Questions

What is the difference between the xTool MetalFab 800W and 1200W?

The primary differences are weld depth, cutting depth, wire feeder, and power requirements. The 800W welds stainless/carbon steel up to 4mm and cuts handheld up to 3mm; the 1200W welds up to 5mm and cuts handheld up to 5mm. Both use the same CNC table, cameras, and software — but the 1200W cuts carbon steel up to 10mm on the CNC table vs 8mm for the 800W. The 1200W includes a free external wire feeder (the 800W has a built-in compact mechanism). The 800W requires a 220V/15A circuit; the 1200W requires 220V/21A. Price difference at Kickstarter: approximately $3,000–$4,000 for the full CNC system.

Is the xTool MetalFab 800W good enough for most welding jobs?

Yes, for most small-to-medium shop fabrication work. The 800W welds steel and stainless steel from 0.2mm up to 4mm — covering automotive bodywork, sheet metal fabrication, light structural brackets, metal art, furniture, and most production welding under 4mm. For brass and aluminum, the ceiling is 3mm. If your regular work stays under these thicknesses (which represents the majority of small shop work), the 800W performs equivalently to the 1200W on material within range.

Does the xTool MetalFab 1200W come with a wire feeder?

Yes — the 1200W welder includes a free wire feeder (xTool Wire Feeder), while the 800W model has a built-in wire feeding mechanism in the torch that is more compact and lightweight. The included 1200W wire feeder supports 0.8mm and 1.0mm wire diameters in stainless and carbon steel, enabling gap bridging, filler weld beads, and build-up applications. This is one of the meaningful non-power differences between the two configurations.

What electrical circuit does the xTool MetalFab require?

The MetalFab operates on 200–240V (not standard US 110V). The 800W model requires a circuit of 15A or higher with a maximum power draw of 3000W. The 1200W model requires a circuit of 21A or higher with a maximum power draw of 4200W. In the US, xTool provides NEMA 6-50P or NEMA 6-30P plugs for different circuit configurations. If your shop doesn't have a compatible 220V circuit, budget for electrical installation ($300–$800 typical) before purchase.

Can the xTool MetalFab 800W cut thick metal on the CNC table?

Yes — the 800W CNC table cuts carbon steel up to 8mm and stainless steel up to 3mm at quality cut specification. CNC cutting at 400mm/s with 0.1mm precision using VibeFreeCut™ and FlexiTrack™ technology applies equally to both models on material within their capability range. For material above 8mm carbon steel or above 3mm stainless on the CNC table, the 1200W is required. For most production CNC part cutting under 8mm carbon steel, the 800W CNC system delivers the full smart nesting, camera, and precision cutting capability.
