I agree with James and Shean. That is exactly how I do it and I have done it 3 X without an incident. Better safe than sorry any day of the week. To be perfectly honest if you have 2-3 people helping you changing out water, and removing the solder ingots, and someone filling them - it shouldn't take long at all.

Later guy's.....

Hi James,

Just a cautionary note to all, and one most people would consider
obvious, please take care to avoid potential molten solder spills into
water and vice versa.  I suspect we all have heard stories or have
personal experiences...let's be safe.

Have a Great Week!

Shean

I WOULD NEVER DRAIN A SOLDER POT. What you need to do and I think Steve
G. will agree is go out and buy a bunch of metal cupcake pans. The real
metal ones not the Aluminum ones. And with a ladle you scoop it out and
pour into the cup cake pan. I should solidify very quickly but if not
you
can put the cupcake pans in a pan of water. It will get the water hot
pretty fast so you will have to change it but as the solder turns hard
you
turn over the pan and the solder ingots pop out. I would never try to
turn on the valve on the side of the pot and drain it that way..... You
really have no control and once you make a mistake your floor will be
covered with solder and people will be jumping on top of anything to get
out of the way of the flow solder river. We once took a couple of 2
inch aluminum plates and machined about 5 troughs in it and scooped the
solder into that. They looked like silver bars when they cooled and like
the cupcake tray they just popped out when you turned it over. It takes
time but you need to take the time to be safe.
Good luck

TechNet:

We are going to drain and clean a wave solder pot in preparation for
conversion to lead-free solder.

We have not completely purged a wave solder pot in some time, and the
people in the know have moved on.

Does anyone have "best practices" recommendations for draining and
handling
the solder (other than BE VERY CAREFUL ! ) ?
