I sense a "don't ask me how I know all this" lurking in the

For the other folks on Technet who may be listening.
Do not allow the solder pot heater to remain on as you drain the last of
the molten solder from the pot. Some molten solder is required to keep the
pot element from overheating. When you get down to the last few pounds of
solder, turn off the pot heater. The remaining solder will stay molten for
a short while in the pot, usually long enough to drain the last of it out.
Refer to your wave solder/selective solder machine manuals for
instructions on how to drain and replenish. Some pots require solder bars
to be cut up into chunks, or as you drain the solder you can pour some off
into muffin pans to form small ingots. Line the bottom of the pot with
these ingots or cut up chunks when you first turn the pot back on. They
will quickly melt and protect the elements from going into thermal
runaway.

Steve,
That's why I described the heater layout to you, so you can activate only
the heaters below the current solder line. As far as getting it out, I'm
almost certain there is a valve on the bottom of the pot. Risky, but
essential.
If I'm mistaken about the drain valve, you could always power it up on its
side and let gravity assist.

Thanks Ed!
I'm learning more & more about this machine as the days tick down, and I
haven't even seen it yet. To further complicate matters, I understand that
there's a couple of hundred pounds of what maybe be SAC307 in the bottom
of the pot, was told that it was analysis was this: 96.17 % Tin, .54 %
copper,
3.18 % silver. The machine is intended to be used as a 63/37 machine, and
getting that residual solder out is going to be a bear because I
understand that the bottom of the pot has what's called a "false bottom"
or welded structure inside, so it's going to be tough. I don't think I can
leave the solder inside the pot with hopes of adding new solder and it
will dilute what's left in the pot down enough for the solder to be within
spec, in fact I'm pretty sure it won't, the silver content is especially
what worries me.
The previous emails from a few days ago about the tin content was with the
existing wave that they have, now they have the -6622 coming in with this
issue. Going to have my hands full when I get to Boise, that's for sure...

Below link says 700Kg = 1543.24. This might be lead-free, so I'd go with
1800 just to be safe.

Hi All!
Does anybody know what the solder pot capacity is of a Vitronics/Soltec
6622CC wave solder machine is with tin/lead solder in it?
The reason I?m asking is because my new employer bought a used ?6622 and
needs to know how much solder they should buy to be able to fill the pot.
They have an old electrovert now that has a 500-lb pot that we?ll be
using, and I told him that wouldn?t be enough to fill the Vitronics
machine. I?m thinking the 6622 holds around 1,600 ?1,800 lbs., but I?m not
sure...
Steve
