The thermostat in our melters works off of reflective heat from the crucible/melting pot. There is no probe or sending unit that tells the thermostat what temperature the lead melt is. The thermostat is encased in a sealed housing and is triggered on and off by how much heat reflects or soaks into the housing from the crucible/melting pot.
It takes approximately 20 minutes once the alloy has melted for the thermostat to stabilize. Once stabilized, you will hear an audible click as the thermostat cycles on and off to maintain the selected heat setting.
You can hook a dimmer switch inline with the cord to control the amperage to the melting pot. This will allow you to run the melting pot at a lower temperature. I will caution, it will take longer to warm up and recover heat when solidified lead is added back to the melt when the amperage is throttled down.
