When a metal is heated to temperatures approaching its melting point, the crystals of which compose the makeup of the metal move apart, opening up microscopic spaces.
The idea behind hard soldering--what is used in making jewelry and requires a heat source (torch) for--is to introduce an alloy (solder) that is fluid just at the point of maximum expansion. The solder flows into the the spaces of the expanded metal, creating a strong bond between the pieces of metal soldered together.
The grip between the two metals is much more than surface-to-surface because the solder has flowed into the microscopic crystals that have opened up in the pieces that are to be joined.
Using a cold-heat soldering tool on jewelry is highly undesirable. Cold-heat soldering--aka soft soldering--uses an alloy of tin, lead and similar metals. Soft solder flows at temperatures about a third of those needed to cause the crystal spaces to open. The holding power of soft solder comes from its ability to fuse onto clean metal. Since the grip is only surface-to-surface, metals joined using soft solder have a substantially weaker join than those hard-soldered together. In addition, soft solder cannot be filed flush without weakening the joint. This is not true of gold or silver solder.
If you are interested in soldering silver and gold--and they are very different processes from one another--I suggest you pick up Tim McCreight's book "The Complete Metalsmith." This book is THE book on metalsmithing techniques and has permanent residence on most jewelers' workbenches.

Hahahahaahhaha sautering!!!!! It's a SOLDERING iron.
How to make your jewelry worthless, solder it with tin.
GO TO A FREAKIN" JEWELER.
Spend $10 for a repair.

best to talk to a jeweller about the gold part as you might need a clean flux for the gold to bond. silver will work as long as it is clean or you can buy acid to clean it with so it sticks or with flux in it. gold is something you don't want to ruin or mess with as due to the expense of it

You will have to try it with gold there is not too much difference in the two metals melting temperatures
