PUK- 2 Spot Welder - Lacy West Jewellery Tools and Supplies

The PUK111 is a small, easy-to-handle point welding device with many advantages. It can be used to position small welding points very precisely, even in deep, hard to get to positions. This makes the PUK-111 especially suitable for fixing work pieces prior to soldering.

Using the electrode clamped in the handpiece, welding points from 0.7 to 2.0 mm in diameter can be fixed. Starting from the point of contact, the arc is lighted and can be precisely controlled by the device during the short burning time.

The heat created by the arc is very low so workpieces can be easily hand held. Temperatures are similar to heat created during laser welding. 8 programs set energy and impulse periods, easily adjustable with a level switch on the device. By using protective gas during welding, oxidation is largely avoided, so that the work piece can be processed further without any additional treatment.

Results are welding points with maximum homogeneity and a smooth as silk feel. Welding is possible for all precious metals and precious metal alloys, plus stainless steel and titanium, as well as bronze, copper and tin alloys.

In general, all metals that are well-suited for arc welding are also suitable for PUK-111 welding. In addition to fix welding, it’s also easy to melt ball shapes, weld loops, close pores or weld smaller joints. This lets you create stable and long-lasting connections, especially in places where soldering is not possible.

Lampert Werktechnik GmbH places a high value on ensuring quality manufacturing of their devices made in Germany. Devices are manufactured according to VDE guidelines and the standard requirements needed for CE certification. The PUK-111 is tested by the German “BG-PRÜFZERT“ and holds the ”GS mark“.

In addition to the proven range of functions and operating concept of the PUK-111, the PUK-2 offers several added features.

Two switches are available to set the impulse length and welding frequency. Larger impulse lengths set using the switch allow increased penetration depth as required, which results in improved strength of welding points. Setting a shorter welding frequency, combined with a stronger power supply, helps you work more quickly. The output range has also been expanded: in addition to smaller welding points, the PUK-2 allows you 30% more performance than the PUK-111.

The functional principle is the same as the PUK-111: as soon as the electrode in the tip of the handpiece touches the work piece, the electric circuit closes and the welding process begins. A small arc is emitted from the point of contact; a small welding point 0.6 – 3 mm in diameter melts the metals together and a stable welding point occurs. By using protective gas during welding, oxidation is largely avoided, so that the work piece can be processed further without any additional treatment. Results are welding points with maximum homogeneity and a smooth as silk feel.

Using the PUK 2, the heat created by the arc is very low. This allows workpieces to be easily held by hand. Welding is possible for all precious metals and precious metal alloys, plus stainless steel and titanium, as well as bronze, copper and tin alloys. In general, all metals that are well-suited for arc welding are also suitable for PUK welding.

All devices are manufactured according to VDE guidelines and based on conformity requirements of the CE designation, and demonstrate high quality production features of equipment made in Germany.

The only elements you operate are the ON-OFF switch and an 8 level output switch.

To work with the welding device you will need the hand piece with a clamped electrode, the welding table and clamp plus the optic unit for eye protection.

When welding using the PUK, please remember these important points in order to achieve optimal results.

To ensure optimal welding results you should always use a suitable protective gas. We recommend argon protective gas with a more than 99% purity. Argon grade 4.6 or greater is recommended. When using protective gas, it is important not to set the flow-through amount too high. 3 litres per minute is normally sufficient. Only in welding situations where the electrode must be clamped for a longer period of time – for instance welding difficult to reach spots – it can be helpful to set a higher flow-through amount.

Before an unpractised user begins welding a piece for the first time we recommend trying some test welding, since welding results and quality depend on several factors. Different metals or alloys react very differently during welding. Metal characteristics such as conductivity, melting points and small amounts of alloy that may escape can greatly influence the welding results. The welding results you receive and the size and depth of welding points all depend on the these factors and not on the strength of material used.

Generally note that metals that are well-suited for welding based on their physical characteristics also produce good results when welded using the PUK Spot Welding Device.
