John gave a very good tutorial on the water torches and I only have
a couple of small comments. Some of you may remember that our Gem
and Mineral Society had obtained two old Krohn torches through a
donation. I subsequently sent them to Krohn in NJ for refurbishing.
I must say that Alex, in the customer service department was very
helpful and got them back to us quickly in great shape. As these
generators are no longer produced, he was able to provide some
reconditioned fluxers and other items to keep the costs down.
One machine was traded for another piece of equipment but the other
has been on our bench at the Society now for about a month. It is
great and one of our members uses it all the time for repair work and
soldering bezels. It is so clean, easy to use, and dependable I wish
they were less expensive as I would love to have one in my own shop.
Perhaps as time goes on and more people use them, the price may come
down a bit.
According to the Krohn manual, some heat control can be attained
through the kind of flux used. The borax, methanol, and acetone mix
provides a steady temperature around 4000 deg but by using only
acetone the temp can go as high as 6000 deg. Otherwise, there is no
adjusting or guessing. Just turn it on and work!
