Temperature does not regulate on Lee 220 volt pot

[Greg G]

I did a search but couldn't find anything.

I have a new 220 volt Lee pot that even on a setting of 2 the temp runs over 700 degrees on a Tel-Tru thermometer.

It came without a plug and I wired one on that matches my 220 outlet at work. I don't know how I could have messed that up. Anyone have an idea what I can look at when I pull the top off to peek inside tomorrow?

I used this pot for 25:1 alloy. It burned out a lot or most of the tin I think before I ordered the thermometers and figured out too much temp was causing the zinc to oxidize out. My Lee 110 volt pot runs perfect.

Thanks!

Maintaining temperature with the thermostat on my Lee pot was a matter of guesswork and constant adjustment. Lee doesn't seem to be calibrate them. The temp also varies depending on how full the pot is. The Tel-Tru thermometers also have calibration issues, but mine at least seems to be consistent. I ended up building a PID temp controller, which solved both problems.
