TUNGSTEN SOLDER PICK WITH HANDLE
TUNGSTEN SOLDER PICK WITH HANDLE
Wood handle with sharp pointed tip for placing, holding and positioning solder in just the right place. For platinum soldering with tungsten tip.
Used for positioning solder while soldering. Tungsten tip is for platinum, as it can withstand the higher temperatures required for such work, and it won’t contaminate platinum like other solder picks will.
It does not appear to be generally known that it is not difficult to solder metals to tungsten; Angerer states that Neusilber (German silver) can be used, but with this exception the general opinion seems to be that welding is the only practical method. In fact, there are a number of metals that will run on tungsten, of which gold, palladium, zinc, and (I believe) nickel are the most important.
The ability to be able to Braze is an asset worth investing in. Silver Solder is a Hard Solder Method and is used for Soldering Tungsten Carbide Tips to Tool Holders and Tungsten Carbide Tips on TCT Saw Blades etc.
Torch Heads are available in various forms from top of the range instant piezo-electric ignition down to a basic pencil flame torch, the one shown in the picture is a middle of the range swivel head torch.
Most Torches can be used with either Propane or MAPP Gas, I prefer the MAPP Gas as this gives a higher heat [150/200°C Higher] and therefore increases your Brazing Capabilities.
MAPP Gas although slightly more expensive it is well worth the extra cost.
Silver Solder is available in numerous grades I use a general purpose Cadmium Free version with a high Silver content of 35% [typically AG35] which has melting temperature of 680/700°C.
The only other requirement is a suitable Flux, in either Powder Form or Pr-Mixed although this has a limited shelf life, you can also purchase pre-fluxed Silver Solder which can be more convenient.
