THEO Welders
Laser Welders
Handheld laser welders for fabricators who measure the day in finished parts — up to 8.5 mm penetration, trained in hours.

Why THEO
Weld up to 8.5 mm in one pass
The MA1 ULTRA drives 8.5 mm of penetration in stainless. Across the range, weld steel, aluminium, titanium and nickel alloys with low heat input — flat parts, clean seams, no post-processing.
Learn it in hours
A 7″ LED touchscreen with factory presets for every material and thickness. Seasoned and first-time welders alike produce consistent welds from day one — no costly training.
Up to 80% less energy
Single-mode fibre technology concentrates energy for high-speed welds without excessive power — up to 80% lower electricity costs than traditional welding.
Advantages of laser welding
Traditional Welding
THEO Laser Welding
Welding Speed
Average
Up to 10 times faster than TIG.
Welding Quality
Highly dependent on user experience. Welding seams can be rough or irregular, requiring rework and polishing.
Consistent high-quality results. Beautiful and neat welding seams, deep molten pool, and high strength. No cleaning necessary.
Training & Learning Curve
Average
Easy — Train in hours. Proficiency in 1–2 weeks.
Heat-Affected Zone
Large
Small
Material Distortion & Deformation
High
Very Low
Welding Seam Damage
Potential for porosity, lack of consistency.
Uniform melt pool and great consistency.
Energy Consumption
High
Low — up to 80% reduction in electricity costs.
Consumables
High welding wire and gas consumption.
Precise wire consumption supported by wire feeding system.

Easy to operate
Master handheld laser welding in an afternoon
The THEO MA1 takes the learning curve out of welding. A 7-inch touchscreen with built-in presets and a multi-language operating system guides operators through every joint, so experienced welders and complete beginners produce clean, repeatable seams from day one — no costly certification, no weeks of practice.

Ergonomic by design
The industry’s lightest laser welding torch — 680 g
At just 680 g (1.5 lb), the MA1 torch is built for full shifts without fatigue. A laser-controlled wobble lays weld beads up to 4 mm wide for smooth, consistent seams, while a double-secured contact sensor only fires when the trigger is in your hand and touching the workpiece.
Explore the MA1 range
One machine, every metal
Weld steel, aluminium and titanium up to 6.5 mm
From stainless, mild and galvanised steel to aluminium, nickel alloys and titanium, the MA1 welds a full range of metals up to 6.5 mm thick at high speed. Low heat input keeps parts flat and distortion-free, and factory presets for every material and thickness deliver strong, clean seams that need no grinding.

Lower running costs
Cut welding energy costs by up to 80%
The MA1’s single-mode fibre source concentrates energy precisely where it’s needed, reaching high welding speeds without drawing excessive power. That’s up to 80% less electricity than conventional welding — measurable savings on every shift that flow straight to your bottom line.

Engineered in-house
Powered by Maxphotonics fibre-laser technology
Every core component of the MA1 is developed in-house by Maxphotonics, a global leader in fibre-laser sources. A proprietary 20 µm fibre core focuses energy into a finer spot for faster throughput at the same power — driving weld penetration as deep as 6.5 mm at 1500 W.

Common questions
What thickness can the MA1 weld?
The MA1 ULTRA welds up to 8.5 mm of stainless in a single pass. The range runs from 3.5 mm (MA1-35) through 4.5 mm (MA1-45) to 6.5 mm (MA1-65) — across steel, aluminium, titanium and nickel alloys.
Do operators need special training?
No welding ticket required. With the 7″ touchscreen and factory presets, most operators are productive within hours and fully proficient in one to two weeks.
Is laser welding safe on the shop floor?
Yes. Every MA1 has a double-secured contact sensor, an emergency-off, an optional door interlock and a safety key lock. With laser-safety glasses and curtains — or a dedicated room — it fits safely into any workshop.
What certifications does the MA1 hold?
The MA1 series is certified to EN 60204-1, EN 60825-1, ISO 11553-2, ISO 12100, EN IEC 61000-6-2 and EN IEC 61000-6-4.
