Many people say that the syringe solder is more expensive, than conventional strip. This is true, but you are paying for the convenience.The solder has flux pre mixed with it and the syringe applicator means you can apply exactly what you need where you need it. Hence, little or no time wasted sanding off the excess later. Due to the accuracy, a little goes along way, so this tube will last a very long time. Perhaps you would not use it for larger items, but for wirework or repairs is perfect. I use this easy version and it does melt very easily. This makes it a superb choice for small delicate repairs such as chain mending or soldering jump rings. Unlike the traditional solder pallions, it stays where its put so you really can put it exactly where you want it, just on the join of a tiny jump ring without getting solder flux everywhere.Whilst the paste does contain flux ready mixed, I do still add a little borax on the jopint, just to prevent the it from oxidising before the solder melts. As always, the golden rules still apply, the joint needs to be clean and close fitting. Do not think that you can squirt a bead of this to fill a hole or gap, it still solder and works the same. Its just the application of it that been made easier.If you do a lot of repairs or perhaps you are into wirework then youll never look back. I have a friend with a repair shop and he uses nothing else. He has a full set off all grades and assays on a wall rack. He claims the increased speed and efficiency of small repairs is well worth the extra little money.I agree!
