PUK welding in the dental laboratory
- Extremely short welding pulse times enable high-quality welded joints to be made with the new dental welder on workpieces < 0.15 mm material thickness
(e.g. e.g. in orthodontic constructions) as well as in heat-sensitive areas (e.g. e.g. in the vicinity of plastic or ceramic parts). - Thanks to the wide performance spectrum of the PUK D6.1, stable dental welded joints can also be produced on very solid parts such as bridges, bars and cast partials.
- The use of appropriate welding wires is recommended.
- Blind operation with one-hand control: the focus always remains on the workpiece.
- Powerful LED illumination in our
premium welding microscopes. Uniform illumination of the working area – flexible use of the microscope: these microscopes can also be used as fully-fledged working microscopes - Setting of all functions, power parameters, pulse duration and menu navigation with a single joystick control knob
- Individual welding device setup via the settings menu
- Very low, controllable heat generation
- Low purchase costs for the PUK D6.1 dental welding unit – also ideal for smaller dental laboratories and independent dental technicians and orthodontists
- Very good price-performance ratio
- Facilitation and time savings during repairs and soldering
- Low costs for consumables
- Low argon consumption
- Maintenance free technology
The advantages of the PUK D6.1 dental welder speak for themselves
Strong and prolonged exposure to heat during conventional TIG welding or soldering with a flame is often undesirable or intolerable in dental technology.
With the new Lampert PUK D6.1 dental welding unit, you not only save time, but also avoid unnecessary material consumption.
In contrast to soldering, fine welding with the PUK D6.1 uses alloys of the same type and thus avoids any unnecessary mix of materials.
This ensures biocompatibility in both the manufacture and repair of dental restorations.
When it comes to precision, reliability and controllability, the PUK D6.1 is the first choice and therefore the ideal complement to CAD/CAM design and additive processes as well as classic casting techniques.
In addition to the classic TIG micropulse welding technology, the PUK D6.1 also offers the practical and proven retention welding function for fast and stable prosthesis repairs or extensions.
- Simple, time-saving and inexpensive procedure for welding stable retention pins
(Ø 1.2 – 2 mm) onto existing dentures in just a few seconds – for repairs, extensions or new fabrications. - In a fraction of a second, a special adapter is used to create an extremely stable connection – without any significant heat development on the denture.
- No re-welding and no post-processing of the weld or its surroundings necessary. As a result, cast partial repairs or extensions can be completed much faster for the dental technician than with conventional techniques.
- Help for safe work with difficult workpiece constructions
- Simple activation: Press the foot switch for 3 seconds – blue symbol appears in the display – welding is now triggered by pressing the foot switch, similar to laser welding.
- Very simple and efficient method for fixing dental workpieces for final welding or soldering. E.g. for a fixation weld of a separated bridge or other dental prosthesis on the working model or to fix wire and construction elements for orthodontic appliances.
- Joining of two metal parts at their point of contact by means of resistance welding – the parts can thus be tacked together for final joining by means of PUK fine welding, or to fix them for a soldering process.
- Especially suitable for machining metals with low electrical conductivity, e.g. stainless steel or titanium.
- Possibility of welding material thicknesses of even less than 0.2 mm, e.g. wires or orthodontic bands, in an even more controlled manner for very delicate dental restorations.
- The fastest selectable welding cycle allows the dental technician an even more continuous workflow.
- Possibility to shape applied material as desired or also to greatly improve the fine welding properties of particularly thermally conductive dental alloys.

PUK D6/D6.1 - Use in modern orthodontics
The specialist journal KIEFERORTHOPÄDIE NACHRICHTEN (issue 9/2023) from the publishing house OEMUS MEDIA AG has published an interesting specialist article which, among other things, also addresses the topic of micropulse welding.
Dr. Seung-Woo Yoo (Neu-Isenburg) and Dr. Matthias Himmelreich (Langen) will shed light on the topic of “Virtual design and fabrication of fixed orthodontic appliances”.
CAD/CAM techniques are now also revolutionizing the design possibilities in orthodontics.
In many cases, the use of a PUK D6 represents the ideal link between design on the screen and SLM (3D printing), casting or milling techniques for the welding of the final appliance.
Read the full article here (German language only) and see for yourself the possibilities of modern precision welding technology in orthodontics.
Practical additional system components and accessories such as electrode grinding motors, flow regulators and much more are available to suit your individual requirements. Please also visit our accessories page.
