Video
See Lampert in action
See for yourself how our micro-TIG technology generates an arc pulse lasting just a few milliseconds, thereby welding the workpiece with virtually no distortion – across a wide range of applications, from traditional metal joints
to electrical connections for sensitive sensor systems.
The video shows seven example applications performed using the Micro Arc Welder: 0.5 mm-thick stainless steel tubes are joined without any rework; a 0.5 mm nickel-chromium thermocouple (Type K) is welded; and 0.3 mm copper connectors are welded to 21700 battery cells. Next, fender panels are welded as part of a classic car restoration, a leak in an aluminum cylinder head is repaired, a damaged ski edge is welded on with steel welding wire (GS2), and a 0.8 mm repair patch is fitted into a fender.

Four devices, one technology
In what ways does micro-TIG welding
make a decisive difference?
Goldsmiths, dental laboratories, developers, prototype builders, and model makers all work according to the same principle, each tailored specifically to their needs. Whenever thin and delicate components need to be welded quickly, precisely, and reliably – with a small heat-affected zone and without warping – micro-TIG welding demonstrates its unbeatable strengths.

What is precision welding?
Precise, accurately metered energy input
Precision welding, technically known as micro-TIG welding or micro-pulse welding, joins metal using individual energy pulses ranging from 0.1 to 34 milliseconds directly at the joint, with filler wire if necessary. Depending on the component, the heat-affected zone remains less than one millimeter, and the workpiece does not warp. This allows for the joining of parts with a material thickness as thin as 0.1 mm—parts that would be damaged by conventional TIG welding.
Pooling energy
The tungsten electrode touches the workpiece, argon flows, and the arc is ignited (pulse duration between 0.1 and 34 milliseconds).
Precision joining
The material fuses together precisely at the joint, and the weld spot measures approximately 0.2 to 4.0 mm.
Continue working immediately
Without the need for a plumb line or curing time, the otherwise time-consuming post-processing is eliminated. The joint is uniform and can bear loads immediately.
Micro-TIG welding or laser?
| Criterion | Micro-TIG Welding (Lampert) | Laser |
|---|---|---|
| Results and quality | High reproducibility and high-quality results, even with highly reflective alloys | High reproducibility and high-quality results; challenges with reflective alloys; advantages for high-speed applications |
| Space requirements | Can be quickly set up at any workstation and used anywhere, even on the go | Requires a large amount of space; enclosure is always required |
| Safety precautions | Eye protection required; for Lampert, use an optical unit or microscope with an integrated protective filter | Comprehensive enclosure required; strict legal requirements depending on national regulations (e.g., laser safety officer) |
| Costs | Lower purchase price, minimal maintenance requirements | Usually more expensive to purchase than micro-TIG welders for comparable quality and results; requires more maintenance |
For repairs, individual parts, prototypes, and small-batch production, micro-TIG welding is almost always the better choice. The additional investment in a laser welding machine is only worthwhile when producing several thousand identical workpieces or when the material thickness is less than 0.1 mm.

5.0 out of 5 stars from 14 reviews on Google
Ich bin mit dem Schweißgerät von Lampert sehr zufrieden. Es erleichtert viele Arbeitsschritte im Goldschmiedealltag deutlich und ermöglicht präzises und effizientes Arbeiten. Besonders schätze ich die zusätzlichen gestalterischen Möglichkeiten, die sich dadurch bei der Anfertigung und Reparatur von Schmuckstücken ergeben. Für meine Werkstatt ist das Gerät eine echte Bereicherung.
The PUK welding machine from Lampert was the starting point for launching my ELIZA WEISS linked Permanent Bracelet Service in early 2020. It has been an absolutely reliable companion ever since, making the precise and delicate work directly on the customer possible when fitting a 'Forever Bracelet'.
I also wouldn’t want to miss it for fine jewelry work in my studio. A great tool and a trusted partner for many years. Thx
great people much information
Das PUK ist einfach genial! 5+ Sterne
A user friendly dental lab or Ortho welding machine
Produziert Schweissgeräte auf höchstem Niveau mit TOP Preis/Leistungsverhältnis. Vom hauchdünnen Blech bis hin zu Konstruktionen im grossen Maßstab ist alles möglich. Der grösste Vorteil: Selbst als ungeübter Einsteiger erlernt man mittels dem PUK Verfahren sehr schnell die Technik und kommt zu perfekten Ergebnissen, für die man mit einem konventionellen WIG Schweissgerät eine langjährige Ausbildung benötigt.

Frequently Asked Questions
What you should know about precision welding
Below, you’ll find answers to the seven questions we’re asked most often over the phone and via email.
You can find more detailed answers to 28 additional questions on our comprehensive FAQ page.
A micro-TIG welder joins metal using individual current pulses ranging from 0.1 to 34 milliseconds instead of a continuous arc. This process is technically known as micro-TIG welding or micro-pulse welding. The tungsten electrode contacts the workpiece, argon flows from the nozzle, the arc ignites, and a weld spot measuring 0.2 to 4.0 mm is formed. Welding is possible on materials with a thickness of 0.1 mm or greater; the heat-affected zone remains less than one millimeter, depending on the component.
Both processes produce welds that are metallurgically comparable. A micro-TIG unit costs a fraction of the price of a laser system, is portable – since the handpiece moves toward the workpiece rather than the other way around – and can be mastered in 30 minutes. A laser safety enclosure is not required, but argon is mandatory as an inert gas. The laser is superior for high-volume production and for structures smaller than 0.1 mm.
Four product series cover four areas of application. Goldsmiths, silversmiths, and watchmakers use the PUK, while dental technicians and orthodontists use the PUK D, which comes with dedicated programs for all common dental alloys. Industry, laboratories, and research rely on the Micro Arc Welder, which ranges from 5 to 1,200 A. For model making and hobbyists, there’s the M280. If you’re unsure which model to choose, a free test weld on your own part can help.
Gold, silver, platinum, and palladium; stainless steel; Grade 2 and Grade 5 titanium; copper; brass; and aluminum, as well as dental alloys such as CoCr and NiCr. As a rule of thumb, anything that can be laser-welded can also be joined using micro-TIG welding technology. Zinc and die-cast zinc cannot be welded because they boil well below the welding temperature. Die-cast zinc can be identified by its light weight and the absence of a hallmark.
High-quality welding results can be achieved after just a brief training period. The process starts automatically as soon as the electrode touches the workpiece. Welding curves are preprogrammed for various alloys and metals, as well as for different workpiece geometries. Only two operating steps are required; after that, the device is ready to weld.
In Werneck, Lower Franconia. Lampert Werktechnik GmbH has been developing, manufacturing, and servicing all of its equipment there for over 20 years; service and replacement parts also come from there. The equipment is CE- and UKCA-compliant. Lampert offers a 3-year warranty on the PUK, PUK D, and M280, and a 1-year warranty on the Micro Arc Welder.
The quickest way is to use the contact form and include a brief description of the workpiece: material, material thickness, and what needs to be joined. If you’re unsure, send us a sample part. The test weld is free of charge, available for material thicknesses of 0.1 mm or greater, and will be returned along with a written welding report and the parameters used.
