Soldering eyeglasses

I am learning to solder eyeglass frames.  I am using 10k gold, hard flux, and an electric soldering machine that can go to 2000 degrees.  My problem is keeping the solder chips on the frames while trying to heat the frame.  And also what temp to use.  the machines number go from 0 -30.  not sure what temp its at.  needs to be about 1350.  any suggestions

Soldering eyeglass frames - I've done that, its tough!!
As to temps. I would contact the manufacturer for information on the settings.  You could do a series of tests, to try and pin the settings down - Hard silver solder is 1425°F, medium is 1390°F; easy is 1325°; 9 kt Gold is 1454 to 1517°F; 12kt gold is 1485 to 1520°F. The text I am using does not list 10kt but 1350°F sounds low

I usually use a titanium pick to place solder when the work is at temp. Gentle heating to get the flux to harden up and stick the chips where you want also can work.

Also - watch out. Enough heat and other joints may separate as their solder melts.

thanks, I also don't have a carbon rod, do I need that, have tried it without, but it gets hot fast, and I read that the carbon rod would keep the heat there.

Hmmmm... Interesting.
Can you tel me where you read that?
It seems like a potential method but I haven't run in to it before.
On the other hand - no, such a rod would not be essential.

I read it in a jewerly repair manual , it actually has pics of soldering with the rod.

One might use such a thing as a solder pick. A solder pick is used to place small solder pieces on to a location for soldering. I have seen discussion of using a pencil lead for a thin carbon rod for a solder pick. They are not real strong, you can find thicker ones at an art supply store.
The pick carries the solder but does not do the heating or carry the heat.
You can but titanium picks or make one out of titanium wire, you may be able get titanium wire spokes at a good bicycle shop.
My apologies for the late reply
