The Easy Way to Solder Leads
I purchased this solder paste to assist in quickly soldering the ends of leads for various applications covering industrial, domestic and musical applications. I have always found that when using a reasonably hot soldering iron it is sometimes not easy to add solder to the end of a lead as the usual scenario is that the insulation starts to melt on the cable before the multicore solder flux can run down and prepare the cable for the solder. Sometimes the cable that you are soldering may not contact the heat as efficiently as it should and also the cable may be old and tarnished, but using solder paste makes life much easier. I have always found that dipping the prepared tip of the cable into a good quality soldering paste is the easiest way of producing the best results and when you touch the tip of the cable with the molten solder on the iron, the solder immediately runs down into the cores of the cable with very little deformation of the insulation. Of course this does depend on the type and quality of the cable and insulation, the worst I have found is on low cost audio cable as the slightest overheating causes the cable to melt through the wall of the insulation, also budget Din plugs and sockets usually will take very little heat without deforming and when soldering multicore plugs it is very easy to overheat the pins and they start to become unstable and loose. I have found that this solder paste is very good quality and does what it says on the tin, I have used it to make up several set of leads from computer to musical instrument and some appliance connections. The secret when soldering on all types of leads is use as little heat duration as possible and with the use of a good quality paste applied to the very tip of the cable or contact being soldered helps greatly in reducing the time spent soldering the end of the cable or the contact, a very good product and highly recommended.

Die Dose war korrodiert. Lack auf die Kappe abbeizeit. Die Lötpaste hat eine komische graue Farbe. Für den Preis, lohnt sich nicht.
