PUK U5

The PUK U5 – mobile and versatile

 
A compact TIG pulse welder: Just where conventional TIG welders reach their technical limits, especially of their lower power ranges, our technology for fine and ultrafine weldings comes into its own – regardless of the size of the workpiece.

 

 

 

 

 

 

 

 

 

 

Facts, that speak for themselves:

  • Superior welding characteristics
  • Consistently reproducible and high quality welding results on all materials suitable for welding
  • Simple and intuitive to operate
  • Precise positioning of the welding points

 

 

  • Very low, controllable development of heat
  • Welding of even the thinnest materials
  • Makes for easier and faster repairs and soldering
  • Precise welding under the welding microscope

  • Maintenance-free technology
  • Low procurement costs, extremely good price/performance ratio
  • Compact size – fits into every workshop
  • Very low costs of consumer materials
  • Low argon consumption

 

 

         

Compact and versatile TIG impulse welding device

On workpieces with a thickness of down to 0.2 mm or even less it is a simple process to produce high-quality welds. That way welding spots with a diameter of approx. 0.2 mm up to more than 3.5 mm can be set (depending on material and setting).

 

  

For daily use

Our welding technology is already successfully in use in over 80 countries in a wide range of different scopes – here are just a few examples:

 

  • Aerospace
  • Automotive industry

PUK’s operating principle is as simple as it is ingenious

As soon as the tip of the electrode of the welding hand piece touches the workpiece, the welding process starts automatically. At the contact point, under an inert gas atmosphere, a melting process takes place.

 

In addition to many sorts of steel, different alloys of titanium, aluminum, copper and tin, as well as various precious metals and alloys are suitable for welding. Generally, all alloys suitable for laser or TIG welding can also be welded with the PUK U5. If necessary, welding wires can easily be fed or added.

Tack welding function

 

For temporarily fixing metal parts

  • Using this process, two metal parts are bonded together at their contact point using resistance welding.

 

  • The parts can be "stuck" together so that they can then be finally attached using PUK welding or so that they can then be soldered.

 

  • The tack welding function is particularly well suited to processing metals with low electrical conductance. For example, steels, titanium, etc.

Resistance welding mode

 

The resistance welding mode can be an option for using individual solutions, e.g. in combination with a force controlled triggering of the weld.

 

  • Corresponding equipment has to be connected to the socket for the foot switch.

 

  • Using this process, two metal parts are bonded together at their contact point using resistance welding.

 

  • To respond to specific material conditions, various welding waveforms can be selected.

             

          

Automatic operation or foot switch

 

Using the foot switch can make work safer and easier when working on difficult workpiece constructions.

  • Activate the foot switch by pressing it down for 3 seconds. The automatic function of the PUK is then deactivated.
  • The white symbol top right on the display signals that foot switch operation is activated.

 

  • Welding is then only triggered when you press the foot switch.

I consider this micro welding machine to be one of my best tool investments.

I have purchased a PUK five years ago to expand my TIG welding to micro level, and never regret for that. Reliability, super easy to start, fast learning curve and lots of hidden capabilities for custom pulse programming - that's exactly what I was looking for. Besides, I would add reasonable argon consumption and ability for micro spot-welding. Maintenance is minimal: just re-fill the argon bottle and have your tungsten clean and sharp.  

 

For readers in North America: Robert from Lampert Tools USA in Chicago provides unbelievable help with order, shipment and delivery, and after I got my machine he gave me free one-day course for micro welding basics. Further customer support and getting consumables is fast, friendly and professional. I consider this micro welding machine to be one of my best tool investments.

I can hardly imagine a work process without the PUK anymore.

There’s really not one day going by in the workshop without the PUK. How quickly this device has made itself indispensable was astonishing - I can hardly imagine a work process without it anymore.

 

Jointing my kinetic works made of stainless steel has particularly become child’s play with the PUK and opened completely new ways of fabrication. No matter if it’s tiniest mechanical elements, sheet metal constructions with a thickness of only 0.3 millimeters or big room sized works, I apply the PUK everywhere and it gets the job done reliably and with a high standard. 

 

The PUK - a tool that I’ve grown fond of and that I want to warmly recommend to all colleagues.

I include the PUK in the design process. Yes, it shapes my design to a certain degree.

For me the PUK has become an inherent part not only in the workshop and for solving problems, I include it in the design process. Yes, it shapes my design to a certain degree. 

 

From the failed attempt to hide welding spots in order to achieve invisible connections emerged the subversive intention to handle the connection spots as obviously as possible. A design idea came into existence that turns the welding spots into my main design feature and orchestrates them like little diamonds. I see that precision technology like Lampert’s spot welding device can - aside from the regular range of applications - produce a high aesthetic value. I want my jewelry to reflect that.

 

The PUK offers clean connections, precise working, new possibilities. It doesn’t just simplify, it paves new ways for jewelry design.

My expectations for the PUK U5+ were very high and were met all along the line.

My expectations for the PUK U5+ were very high and were met all along the line. Working with the PUK U5+ is very simple and uncomplicated.

 

An artist carefully compiles his tools because he uses them to express his thoughts and ideas through his hands. The high expectations of yourself must also be placed on the tools. That is why I only work with professional tools and machines.

For the production of my kinetic solar sculptures I prefer to use round steel rods up to 4 mm and sheets up to 1 mm thick. In the past years I have tried many techniques to optimally combine these materials. I have already used some processes, such as TIG welding, brazing with hydrogen, spot welding or soft soldering. None of these connection techniques met my high standards.

One day I became aware of the PUK U5+ welding system from Lampert, which I had never seen before. The first-class technical support from the Lampert company was able to advise me "on point" what the possibilities of the PUK U5+ are.

My expectations for the PUK U5+ were very high. But these were met all along the line. Working with the PUK U5+ is very simple and uncomplicated. It feels like holding a thick pencil in your hand, easy to handle, safe and accurate.

I usually only rave about Swiss made machines. But I with pleasure took the PUK U5+ from Lampert, made in Germany, in my train of machines.

Working with PUK 2 since 2006.

 

My favorite cocktail is; PUK, argon and titanium.

If I didn't have the PUK I wouldn't have been able to make some of my best titanium pieces.

I bought my PUK2 in 2006, right at the time I opened my own workshop: www.josemarin.net.

 

At first, I used it in the creation of gold and platinum jewellery and in these three directions:

  1. Repairing delicate pieces with precious stones which cannot be subjected to fire, this allows me to intervene on the jewels without dismantling the stones.
  2. Pre-assembly of complex parts that I must later weld with a port of soldering and the aid of the torch.
  3. Creation of impossible pieces. For example, mounting a platinum band with diamonds passing over an emerald, this would be unthinkable by the traditional method of fire welding.

 

At present it is my great help for the creation of my pieces of titanium and Timascus, so far I have managed to do everything I set out to do.

 

I must admit that my PUK2 is a very old version, with limitations for silver and bronze, but otherwise it is a perfect machine and very resistant, in 14 years I have not had any breakdowns.

As my brother and me started our own business, the PUK 5 was our first purchase along with two workbenches. We both had very good experience with the PUK 2 and PUK 04 and therefore knew that this wonderful device would become indispensable for us.

 

The PUK can be summarized in one sentence: "easy to learn and hard to master". Anyone could tack weld and joint parts after a few minutes. But the incredibly diverse possible field of application arises over the time and growing experience. Due to the very well calibrated default settings that the PUK 5 comes with, you can take countless challenges directly. With the experience at what angle, from what side and with which setting the respective welds work best, the joints are getting cleaner.

 

We work with the welder every day and the results are impressive and yet we have the feeling that we have not yet exhausted the "PUK potential".

With the PUK I brought building custom made radio-controlled construction models to the next level!

I am a perfectionist and I try to build my radio-controlled construction models to the highest quality and detail. I was looking for a device that can actually allow me to achieve this goal. Previously I was not able to work with steel or stainless steel, and because of the fine detail and precision work I was not able to weld with a normal TIG welder. I was recommended by a mate of mine who saw a demonstration of the PUK welder at an expo. I contacted LAMPERT, explained situation and they advised me the exact equipment I needed. Early 2017 I purchased the M200 which was shipped to Australia. LAMPERT guided me in the initial stages via Skype support how to use the machine. This was very clear and now after almost 3 years of use I cannot do without it. The amount of precision and welding size exactly replicates the scale and strength needed for my models. I am now able to work with various materials and stainless steel is my favorite. I highly recommend this machine to any serious and professional model builder.

Lampert PUK a must for every Jeweller

 

I invested in a PUK 5 welder and was able to obtain a pay back within 6 Months. The PUK enables me to do additional repair and restoration of jewellery over traditional flame soldering methods through less heat dispersion, pinpoint control and seamless joints. I selected the PUK 5 over other welders for its quality, support service, no maintenance requirements and end welding results.

The PUK proves itself invaluable – no matter the metal or alloy.

 

 

read more 

I have used various models of the PUK over the past 15 years and currently have a PUK5 at my bench. I have yet to find a more versatile machine for a jeweller’s workshop. Only imagination limits application where the PUK is involved. Whether its mounting, repair work, stone setting, engraving, or otherwise, the PUK proves itself invaluable – no matter the metal or alloy.
