Yes, always the problem of dealing with sight unseen equipment. Been
there a few times myself.
It always amazes me that sometimes management balks at spending $10K more
on something, because then is crosses some arbitrary line in accounting,
or it necessitates generating a purchase order and dealing with
purchasing. Yet, they think nothing of spending $10K in valuable
engineers time because the money is classified differently.
I guess the big question comes down to the negative consequences of poor
solder joints. If you are building garage door openers, no one dies if
the solder joints go bad. Pacemaker, Jet Engine control module, different
story. I like the way my esteemed colleague Hillman puts things - in
terms of being in front of a 60 Minutes interview. Can you explain why
these 200 people died because your company was too cheap to buy a new
solder pot? Sometimes helps to put things in perspective.

Wave solder machine
Hi Doug,
Seeing how I haven't even laid eyes on the machine yet, and I don't think
my
boss bought the machine thinking that he was going to have to replace the
pot, it may be a little early in the game to even suggest that. That said,
nothing is as easy as it first seems. I'm just learning about the
situation
about the residual solder in the pot. I've never had the experience of
dealing with this situation of having solder left in the bottom of the pot
that's a completely different alloy than what's going to be used. So I'm
humbly asking for any pointers that maybe someone can help me with. I've
gotten some very good ones already. Ed Popielarski's advice has been
invaluable to me, I hope I'm not becoming too much of a pest to him.
I'm sure I'm going to learn some more new fun things about the machine
once
I actually get a chance to actually see it in a few weeks... ;o)
Steve

Steve,
Let me ask a dumb question - why not just buy a new solder reservoir, save
yourself the hassle and labor, and sell the whole pot to a reclaimer?

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
