Any quirks to using a Lee Pro 4-20 melter?

[hans g./UpS]

I'll be casting 58,62 and 72 caliber roundballs with[hopefully] pure lead with a Lee Pro 4-20 [700 watt] electric melter.This melter has a bottom pour.I have Lee roundball molds.The last time I used to occasionally cast roundballs with a dipper out of a pot on top of a backpacking gasoline stove, was ~10 years ago.
Any quirks to the process with this melter?
Thanks.

First, keep a metal pan under the pour spout.  It has a tendency to start leaking when you least expect it.
Second, I keep a propane torch handy to thaw the occasional "spout freeze".
Last, develop a consistent technique, for example, always keep at least .5" of clearance between the mold and the spout, always make the sprue puddle about the same size, etc.  And no, I'm not saying you need, or don't need, clearance between the mold and spout, just figure what works well for your mold, and stick to it.

What bpjon said.
I keep a Lodge spoon holder/ashtray I got at  Wal-Mart under the pot. It looks like a miniature  cast iron skillet and fits just fine. I don't have enough trouble with spout freeze ups to warrant the use of a torch at hand, but I do keep a screwdriver or two close by in case I have to adjust the flow or in an attempt to stop a leak.
 I think ALL lee pots leak to some extent, but the get the job done. I have two,  and both have the bottom spout, and both leak when THEY want to.  It's a minor thing, but distracting at times.

i have learned to only use clean lead, do your ingot makeing with a 10 qt cast iron pot on a turkey cooker,and never run a bottom pour pot empty,that is keep an inch of lead in the pot so the floating stuff is away from the spout!
