I have a difficult repair problem,
It is a tank in a Slushie machine, it is made of .035" stainless, and I can
only get to one side of the tank.
The hole is small, about 3/32" in diameter, it is from a rub spot inside the
tank (the source can be fixed).
The bad part about this is, the tank has refrigeration coils around it (I
don't know exactly where they run) it also has foamed in place insulation
over this, and a stainless shell over this.
I don't mind burning some of the insulation, I would like to do this from
the inside of the tank. What ever I do has to be compatable with food
service, the mix in the tank is sugar water and citric acid.
My thoughts are using a Micro-torch and silver braze.
Epoxie would be great, but I don't know if they make food grade, and I don't
know if it would hold up.
TIG was a thought, but I would have to cut open the shell, and remove
What do you guys think ? What silver braze has the lowest melting point ?
Any better ideas are welcome.
