top view of salt pot used for heat treating my blades. The programable controller turns gas on until heat reaches 1550, then shuts the gas off. When the heat drops to 1546 degrees it turns the gas back on and the venturi burners relight and it just keeps cycling on and off to hold the parameters. It will coast a little past high and low settings by about five to eight degrees before the heat catches up. |
