Convert soder machine to tack welder

Jewelry Discussion

I have an old electric soldering machine that I never use.I’d like to
use it as a tack welder. Has anyone any on the proper
way to do this?

To convert the machine from soldering to tacking you need to make a
set of copper tweezers with a cylindrical base so that you can slide
out the carbon and slide in the tweezers. I used a piece of 8 mm
brass tubing I purchased at a hobby shop, flattened one end and soft
lead soldered a piece of copper shaped like tweezers into it. This
works great for gold and platinum, however it does not work at all
for silver.

Have fun,
