Xlaserlab X1 Pro vs. X1 Base

Same Brand, Very Different Value Propositions

When Xlaserlab launched both the X1 and X1 Pro on Kickstarter in March 2025 — raising over $3 million in days — buyers had an immediate decision to make: the more accessible X1 or the more powerful X1 Pro.

The surface spec comparison looks like a simple wattage question: 460W versus 700W. But the more important difference is the laser technology itself. The X1 uses a semiconductor diode laser with a larger fiber core designed for even energy distribution. The X1 Pro uses a fiber laser with a 14µm fiber core that concentrates energy into a dramatically smaller spot — the same principle behind the Theo MA1's 20µm core advantage, applied at a lower price tier.

This isn't just a marketing distinction. It determines which materials each machine handles reliably, how deep each can weld, and which workflow integrations are possible. The X1 is precision-oriented for thin material. The X1 Pro is the all-around production machine.

For the complete review of the X1 Pro — including real-world user feedback, the Halfass Kustoms independent assessment, and The Maker's Chest's evaluation — see our Xlaserlab X1 Pro review.

Xlaserlab X1: Core Specs and Ideal Use Cases

Power and Weld Capability

The X1 runs a 460W semiconductor diode laser. This technology uses a larger fiber core that distributes energy more evenly across the beam — the result is a wider, gentler energy profile suited to thin, precise work.

Published specs from Xlaserlab:

• Laser type: Semiconductor diode laser, larger fiber core
• Laser power: 460W average
• Weld range: 0.2mm – 2mm (optimal range)
• Weight: 13kg
• Interface: Analog dial controls (no touchscreen)
• Voltage: Standard input
• Functions: Welding, cleaning, rust removal

The X1 welds material from 0.2mm (ultra-thin sheet) to 2mm effectively. At the 0.2mm end, the even energy distribution from the larger diode core is actually an advantage over the X1 Pro's more concentrated fiber beam — it's more forgiving on material that can burn through under high energy density.

Build and Form Factor

At 13kg, the X1 is the lighter machine — meaningfully more portable than the X1 Pro. The analog dial interface is intentional rather than a cost-cut: X1 operators can adjust power and pulse duration without navigating menus, staying in their rhythm on repetitive fine welds.

The X1 also has underwater welding capability — a feature both models share, but practically more useful in the X1's lighter, more compact form factor for on-site and field work.

Who the Base X1 Is Designed For

The X1 excels in dexterity and precision, specifically designed for fine processing of thin materials. The buyer profile it serves:

• Jewellery and fine metalwork — delicate weld work on thin precious metals where the even beam distribution prevents burn-through
• Art and decorative metalwork — high-precision spot welds on thin stainless or carbon steel artistic work
• Repetitive thin-material production — if your workflow is hundreds of identical spot welds on 0.5–1.5mm sheet, the X1's analog simplicity and lighter weight serve this focus better than the X1 Pro's broader feature set
• Buyers who need maximum portability — the 13kg weight and standard voltage input make it the easier machine to move between sites
• Budget-limited buyers who primarily work on thin material and don't need the multi-function capability or thicker material depth of the X1 Pro

Xlaserlab X1 Pro: What the Upgrade Adds

Power and Weld Depth Improvements

The X1 Pro runs a 700W fiber laser with a 14µm fiber core. This smaller core concentrates the 700W into a dramatically smaller spot than the X1's diode core — higher peak energy density at the weld point, faster heat penetration, and the ability to drive fusion deeper into thicker material in a single pass.

Published specs from Xlaserlab:

• Laser type: Fiber laser, 14µm core diameter
• Laser power: 700W average
• Weld range: 0.2mm – 3mm+ (up to 5mm structural stock in Xlaserlab's documentation)
• Interface: 7-inch colour touchscreen
• Voltage: 100V–250V wide voltage (standard household and workshop power worldwide)
• Weight: 17kg (estimated, heavier than X1 due to additional components)
• Price: $3,699–$4,699 direct from Xlaserlab or authorised retailers

The X1 Pro welds stainless steel and carbon steel up to 3mm in a single pass with clean results. Xlaserlab's product page states it handles material from 0.2mm to 5mm structural stock. The 3mm single-pass specification is the more reliable practical benchmark for production work.

Additional Functions and the 6-in-1 Design

The X1 Pro markets itself as 4-in-1 (some configurations describe 6 functions): welding, cutting, laser cleaning, rust removal, and with CNC retrofit, automated operation. The practical daily-use functions are the primary four.

Cutting: The X1 Pro can cut stainless steel and carbon steel up to 3mm thick in a single pass, and aluminum up to 1.8mm. The X1's lower power level limits its cutting capability more significantly.

Laser cleaning: Pre-weld surface preparation (rust, paint, oxide, grease) and post-weld cleaning (soot, discolouration). For the complete picture of what laser cleaning offers and when it matters, our what is laser cleaning guide covers the process in detail. The X1 also has cleaning capability, but the X1 Pro's higher power makes cleaning faster and more effective on heavier contamination.

CNC integration: The X1 Pro's control system supports integration with numerical control machines for automated, repeatable cutting operations. This is relevant for shops planning to use the machine in a semi-automated production context.

Wire Feeder and Advanced Features

The X1 Pro supports an external wire feeder — a feature the base X1 does not have. This allows operators to add filler material to the molten pool during welding, which enables:

• Gap filling — bridging gaps in poorly fitted joints that would otherwise require precise fit-up
• Material build-up — adding material to worn surfaces or creating fillet welds with material
• MIG-style production welding — the wire feeder makes the X1 Pro a viable high-speed alternative for MIG applications where the laser's cleaner finish and lower heat input are advantages

This is the feature gap that matters most for professional fabricators. Without a wire feeder, laser welding requires tight joint fit-up for consistent results. The wire feeder gives the X1 Pro the tolerance for real-world fitment variation that the X1 lacks.

Underwater Welding and Environmental Range

Both X1 and X1 Pro support underwater welding. The X1 Pro's wide voltage input (100V–250V) and robust build make it more practical for diverse environments. The X1 Pro's waterproofing and environmental tolerance are documented in Xlaserlab's product materials.

The 100V–250V wide voltage input is specifically worth noting for international use and for sites with variable power infrastructure. Standard workshop power anywhere in the world runs the X1 Pro without modification — no industrial electrical requirements.

Comparison: X1 vs. X1 Pro Across Key Criteria

Welding Performance

The performance difference is most significant on three fronts: material above 2mm (X1 Pro only), thermally conductive metals like aluminium and copper (X1 Pro's higher energy density overcomes conductivity), and cutting (X1 Pro handles 3mm stainless; X1 is limited by lower power).

On thin steel and stainless under 1.5mm: both machines perform comparably. The X1 Pro's higher energy density makes its process window on thin material slightly less forgiving than the X1's distributed beam — though with the preset system and pulsed mode, thin material on the X1 Pro is well-managed.

Versatility

The X1 Pro is comprehensively more versatile: wire feeder capability, CNC integration, more effective cutting and cleaning, and wider material and thickness range. The X1 Pro's 7-inch touchscreen with preset system makes it faster to switch between modes, materials, and parameters in a mixed-work environment.

The X1's comparative advantage is precision and simplicity on thin material. For a workflow that is entirely thin-material welding, the X1's focused design may actually be preferable.

Ease of Use

The machines take opposite approaches to the operator interface:

X1 analog dial: Set power and pulse duration once, then weld without menus. Ideal for single-task focused operators who are doing repetitive work and don't want interface friction.

X1 Pro touchscreen (7-inch, presets): Broader parameter control, preset library for different materials and thicknesses, faster onboarding for operators who need to work across multiple configurations. The preset system means beginners can select material and thickness and begin welding without understanding the underlying parameters.

For most buyers: the X1 Pro's touchscreen with preset system is the more accessible starting experience. The X1's analog interface is faster once you've learned it for your specific application.

Price Jump: Is It Justified?

The X1's pricing hasn't been publicly confirmed at a single retail price as clearly as the X1 Pro's — based on Kickstarter early-backer pricing (approximately $1,699 early-bird) and current market positioning, it sits meaningfully below the X1 Pro's $3,699–$4,699 direct price. The price gap between the two models is substantial.

For the X1 Pro price premium to be justified, you need at least one of:

• Regular work on material above 2mm
• Aluminium, copper, or thermally conductive metals as part of your workflow
• Cutting capability as a daily function
• Wire feeder use for gap-bridging or build-up
• The preset system's value for operator onboarding

If your work is exclusively thin steel and stainless under 1.5mm and you don't need cutting capability: the X1's price advantage is real and the X1 Pro's additional capability goes unused.

Who Should Buy the X1?

The X1 is the right choice for:

• Jewellery, fine art, and precision thin-metal work where the diode laser's even beam distribution is actually preferable over the X1 Pro's more concentrated fiber beam on material under 1mm
• Highly focused single-task workflows — if you're welding the same joint on the same material all day, the X1's analog simplicity and lighter weight serve you better than the X1 Pro's feature set
• Maximum portability at minimum weight — at 13kg, the X1 is significantly easier to move and position for on-site or field work
• Budget-limited buyers whose work stays under 2mm — if 2mm is your practical ceiling, the X1 covers the application and the price saving is real
• Underwater welding specialists for whom portability is the priority function

Who Should Buy the X1 Pro?

The X1 Pro is the right choice for:

• General fabrication shops doing mixed work across steel, stainless, and aluminum in the 0.5–3mm range — the X1 Pro's broader capability serves a mixed workflow far better
• Automotive restoration and bodywork — the combination of 700W fiber power, pulsed mode for thin aluminum, continuous mode for longer steel seams, and cleaning/rust removal makes the X1 Pro a complete automotive fabrication tool
• Anyone who needs wire feeder capability for gap bridging, build-up, or MIG-replacement work
• Buyers expecting to cut metal regularly — the X1 Pro's 3mm stainless/1.8mm aluminium cutting capability is production-usable; the X1's lower power limits this
• Buyers who want a single all-purpose machine covering welding, cutting, cleaning, and rust removal in one unit
• Operators new to laser welding who will benefit from the preset system's guided parameter selection for different materials
• Any application involving aluminium or copper where the X1 Pro's higher energy density from the 14µm fiber core manages thermal conductivity more effectively

Verdict

The X1 and X1 Pro are not simply the same machine at different power levels — they use different laser technologies with different energy profiles, and these differences drive real application differences.

Buy the X1 if: your work is precision thin-material welding under 2mm, you value the analog simplicity and light weight, and you don't need cutting capability, wire feeder, or the versatility to move across materials and thicknesses.

Buy the X1 Pro if: you do any work above 2mm, need aluminium or copper capability, want integrated cutting and cleaning, or benefit from the preset system's operator accessibility. For most fabrication shops doing mixed work across real automotive, structural, and sheet metal applications — the X1 Pro is the correct machine.

The price gap is real. But for anyone whose work regularly touches the X1 Pro's specific advantages — depth, cutting, copper, wire feeder — the capability difference justifies the cost.

Frequently Asked Questions

What is the difference between the Xlaserlab X1 and X1 Pro?

The primary difference is laser technology. The X1 uses a semiconductor diode laser with a larger fiber core providing even energy distribution — optimised for thin, precise work on 0.2–2mm material. The X1 Pro uses a fiber laser with a 14µm fiber core that concentrates 700W into a smaller spot, providing higher energy density for deeper penetration, better thermally-conductive metal capability, and effective cutting. The X1 Pro also adds a 7-inch touchscreen with preset system, wire feeder support, stronger cutting capability (up to 3mm stainless), and the full 4-in-1 function set including cleaning, rust removal, and CNC integration.

Is the Xlaserlab X1 Pro worth it over the X1?

For mixed fabrication work on steel, stainless, and aluminum across 0.5–3mm: yes. For exclusively thin precision work under 1.5mm where you don't need cutting capability or wire feeder: the X1's price advantage is meaningful. The X1 Pro's wire feeder support is the most significant practical advantage for professional fabricators — it allows gap bridging and fillet work that requires tight fit-up without filler on the X1. If any of the following apply to your work: material above 2mm, aluminum or copper, cutting, wire feeder use — the X1 Pro is the correct machine.

What can the Xlaserlab X1 Pro weld that the X1 cannot?

The X1 Pro handles material up to 3mm in a single pass; the X1's optimal range tops out at 2mm. The X1 Pro welds aluminium, copper, and thermally conductive metals more effectively due to its higher energy density from the 14µm fiber core. The X1 Pro supports external wire feeder for gap bridging and build-up welding that the X1 cannot do. The X1 Pro also cuts stainless and carbon steel up to 3mm effectively; the X1's 460W limits cutting performance more significantly.

Can the Xlaserlab X1 Pro weld aluminum?

Yes — the X1 Pro welds aluminum 3 and 5 series effectively, handling material from thin sheet up to approximately 1.8mm in regular fabrication use. The 14µm fiber core's higher energy density is specifically relevant for aluminum because aluminium's high thermal conductivity rapidly disperses heat from the weld zone — higher energy density per unit area is needed to achieve fusion before the heat dissipates. The X1's lower power and larger core makes aluminium welding more challenging. For detailed guidance on aluminium-specific laser welding parameters and challenges, see our why aluminum is tricky to laser weld guide.

How much does the Xlaserlab X1 Pro cost?

The Xlaserlab X1 Pro is priced at $3,699–$4,699 when purchased directly from Xlaserlab or through authorised retailers like The Maker's Chest. Third-party Amazon and reseller listings typically run $6,999–$7,899, reflecting retailer margin above the direct price. Financing options are available through some retailers. The X1 (base model) was available at early-backer Kickstarter pricing of approximately $1,699, with current retail pricing significantly below the X1 Pro — the exact retail gap depends on current availability through Xlaserlab's direct and retail channels.
