Just received the above furnace. After seven years with my Lee pots, decided to change. Had my first casting session last Friday. Long story short, I had to turn the temp dial to the highest setting to achieve 600-625 degrees. Believe the temp markings were either 750 or 850. Can't remember. Have any of you had the same experience? Thermostat markings only for reference? Other than that, pleased with the results. For the record, both of my Lee pots, turned to the highest settings, only reach 600-625 degrees.
