Old ProMelt was on it's last legs - something like 2+ tons lead through it.
Fired it up, stacked ingots in the middle, sacrificed some 9mm cast to fill in the gaps to help keep hot spots to a minimum.
So, set PID to 750 deg (sure seems to take a while to get to temp) maybe 15 min longer than old RCBS (before it died).
Melt seems "thick", spout wants to freeze up when pressure pouring (yep, mould was hot).
Pulled the Lyman dial therm off old pot, stuck in the new pot, reading 650. Yep, PID still says 750.
Set PID to 800, Lyman reads 700, casting like a champ.
Any one else run into this ?
Not a huge issue, just have to run PID at a higher setting to get a certain temp.
But for it's healthy price, I'd expect better.
Rant over, think I'll cast some more.
