All welding equipment can be handed in for disposal at the end of its service life at Lampert Werktechnik Gmbh, Ettlebener Straße 27, 97440 Werneck from Monday to Friday from […]
The electrodes used are a special alloy of tungsten and metal oxides. These electrodes have been specially designed for use in conjunction with Lampert fine welding equipment. The electrodes have […]
The protective gas flow rate is set too high:Make sure that the flow rate is set correctly. 2 – 3 liters/min are completely sufficient (this corresponds to approximately 0.4 bar)! […]
To adjust the flow rate, turn on your PUK and carefully open the valve of the gas cylinder. On the PUK 3, press the power control on the device; on […]
Visit the home page of our “PUK Master” Jeffrey Herman http://www.hermansilver.com and his new blog http://www.silversmithing.com/puk.htm. Here you will find a variety of applications from the silversmithing field.
Solder tends to burn during welding due to its additives, so it is not suitable as a filler metal. Also, if possible, do not weld at solder joints, or alternatively, […]
Metals with high thermal conductivity are generally difficult to weld, but: The thermal conductivity of silver decreases as its temperature increases. This means that silver can be welded better when […]
In principle, soldering – where usefully applicable – is usually considered the ideal joining technique in jewelry manufacturing. Nevertheless, there are a variety of applications in jewelry making and repair […]
The pulse time is mainly responsible for the penetration depth of the spot weld. The longer – the deeper. For very thin material, always work with the shortest possible pulse […]
In general, it can be said that the power controls the diameter of the spot weld. Although higher energy also increases the penetration depth of the weld puck, the welds […]
If the material thickness of the workpiece at the fracture point is greater than 1.0 mm, the penetration depth of the welding device is not sufficient. The fracture must then […]
The time between two welds is 0.8 to 2.0 seconds. It automatically adjusts to the operator’s working speed. I.e. with a fast welding sequence, the time span is automatically reduced […]
It is a noble gas and a natural component of air. Like all noble gases, it does not react: it cannot burn and is not toxic. Nevertheless, care should be […]
In an average goldsmith’s workshop, one filling of a 10-liter bottle will last for about 6 to 12 months, depending on how intensively welding is done with the PUK.
The heat generated during welding is very low. Especially for heat-sensitive areas such as gemstones, it is recommended to work with the shortest possible pulse time (the PUK04 already has […]
Yes – Even metals with very different properties can be welded, e.g. gold with titanium. However, if the physical differences are too great, as is the case with titanium and […]
A special aluminum mode is stored in the current PUK model. With this mode, aluminum alloys suitable for welding can be welded particularly well by feeding welding wire. It is […]
In the current model a brass mode is stored, with this brass alloys with low zinc content can be welded well.
Basically, all precious metals and precious metal alloys of gold, silver, platinum and palladium can be welded. In addition, all metals can be welded that are also weldable by laser […]
The technique of PUK welding is easy to learn. Nevertheless, you should take a few hours to familiarize yourself with the device. The PUK course, which is included in the […]
The angle plays an extraordinarily significant role. The highest penetration depth is achieved at a 90° angle to the workpiece. When the electrode is placed at an angle, the metal […]
Maintenance is not necessary! In normal operation, only minor costs are incurred for shielding gas and due to wear of the electrode.
The microscope is equipped with an electronically controlled, DIN-certified eye protection filter. This ensures triple protection of the eyes: permanent protection against glare from UV and IR light and electronically […]
Workpieces are selectively melted and thus joined together. Ideally, filler metal always has the same melting temperature as the workpiece itself (in brazing, a brazing alloy is always used which […]
The PUK is a fine welding machine based on TIG welding technology. It generates an arc, also called plasma, for a brief moment, which generates a spot weld. The welding […]
