So far I have had good results remelting the offending bars and holding the temperature less than 700F to get rid of Zinc.
Zinc melts at 787F has SG of 65 so it floats on top and can be skimmed off....

Addressing a failed SSR
Like HATCH I've never seen a failed on.
Failed on could be gating circuit bad or shorted output device likely a MOSFET.
It takes power to gate so that wouldn't seem likely...

HATCH in Post #40 is the only one so far that I think got the heat sink correct.
Maybe his dealing with them for over 25 years explains it.
Just screw it to the metal box.

I couldn't get SL8 (PV bias) works either.
That's to remove offset in PV ie to tune out sensor offset so PV is correct.
But then for the price I don't care if there is a 3 or 4 degree offset in...

The sticky on SOWW makes a mess in the smelt pot but seems like good flux.
I keep the SOWW that feel / cut like pure lead (which is most of them) separate. The LEE hardness tester shows them much...

Hit LASC and read up on what additives are needed to harden lead. There are also plenty of threads on CB addressing the issue.

Hi Glen and welcome to casting.
