Blowtorch Lötmeister PZ5000

We have silver braided bars with a silver content of 55% (L-Ag55) with a length of 500mm. Because of the relatively low melting point of this silver braze, the model builder in the field of technical model building is almost exclusively concerned. The working temperature of this hard solder is 630 ° C. The silver as an alloying component in the solder does not only reduce the working temperature, but also improves the flow properties. Furthermore, silver has the positive property of combining well with other metals. For brazing brass and steel, silver solder flux is essential. The low working temperature of the silver solder bars allows the thermal load to be as low as possible for the processed material. It is important not to heat the workpieces too much, especially in the case of brass. In combination with our silver solder flux you achieve with these silver solder always optimal results. The silver braided bars can be purchased from us in the shop in 2 different diameters. For fine soldering as it often happens in technical model construction we recommend the 1mm rods. The 1mm silver braided bars are easy to carry with the hand and can be easily melted with small burners. For larger parts we prefer the 1.5 mm silver solder bars. With these rods you get faster material to the soldering point if needed. What can be brazed?The following materials can be combined with silver solder: brass, copper, gunmetal, gray cast iron, rusting steels and stainless steel. A combination of the materials among each other is easily possible with this silver braze solder. If the material is not known to you, it is always recommended to solder a piece to the sample beforehand. This allows you to determine whether the materials can be combined with the silver braze.Instructions Brazing with silver solder If you have never worked on silver solder and you are not sure how the exact solder brazing procedure is with silver solder, we can help you before you buy the silver solder. We have created a guide for you in our Bengs Modellbaumagazin on the topic "Brazing with silver solder". Here you can find out what you need and have to consider if you want to solder 2 components with silver solder. Tip: Flux residues and discoloration of the material can be optimally eliminated with our satin brushes or abrasive fleece!Characteristics of the silver solder bars500 mm long. 1mm or 1.5mm diameter Silver solder bars L-Ag55 (55% silver) Working temperature 630 ° C Bengs Modellbau has used this silver solder bars for years.  

When brazing, fluxes have the task of loosening and removing the oxide layers present on the soldering surfaces and preventing them from forming again during soldering. The flux is adjusted to the working temperature of our Silver hard solder matched. Before use, the flux for silver solder should be stirred well. Using the brush in the bottle, a thin layer can be applied to the component to be soldered. You can find detailed instructions in our model making magazine (Hard soldering with silver solder instructions). If the silver brazing flux has dried out, you can make it liquid again with distilled water. Brazing with silver solder rods without flux is not possible. When the flux is heated with the burner, the water it contains first evaporates. This can be seen in the final formation of small bubbles. When the component is heated further with the flux and the working temperature is reached, the flux paste begins to melt and becomes transparent. Now the moment has come where the silver solder can be added. The effective range of the flux for silver solder is between 500°C and 800°C. The flux is suitable for brazing copper, brass, gunmetal, steel and stainless steel. Tip: Flux residues and discoloration of the material can be optimally removed with our Satin brushes or remove with abrasive fleece. You can get the flux for silver solder from us in the packaging sizes: 50g. Bottle with brush 100g.Bottle without brush

The gas blowtorch has a sturdy and durable plastic foot. This soldering torch is suitable for brazing and soldering. The flame size can be adjusted via a rotary wheel. The Bunsen burner has a maximum working temperature of 730 ° C and a maximum flame temperature of 1750 ° C. The gas burner is ignited via a push button with a piezo ignition. The soldering torch is an optimal tool for the model builder, space-saving, safe and inexpensive. The gas burner is best suited for brazing with silver solder from Bengs Modellbau. However, the soldering torch is also suitable for soldering large parts, such as the cylinder and the mirror, in a brass model building machine. The burner only operates in a horizontal position. The torch is operated with standard camping gas cartridges. Replacement cartridges are also available in our shop. Just select the desired item at the top of the variant. Standard camping gas kits (190g) are suitable for operation. A gas cartridge is included in the delivery. You can always order replacement parts from us at any time.

The white soldering brick is ideal as a soldering base for brazing and soldering in model building. The solder seal can be cut as required. In addition, soldering and holding needles can be inserted very easily into the brick in order to fix the component to be soldered. The white tiles have a relatively smooth and plane surface, through which sharp edges several bricks can be assembled seamlessly. To fix components that are to be soldered, you can simply nail into the porous material of the soldering iron. Thus, a soldering device can be produced very quickly. The soldering bricks are also suitable for the construction of a melting point. By assembling several soldering bricks, one can produce an excellent soldering place in which the gas flame of the burner can be optimally utilized. Dimensions of the brazier: 220mm x 110mm x 30mm
