Standard/Everyday Use
Wear Personal Protective Equipment
Before approaching and working with the salt bath kiln wear all personal protective gear which includes a face shield, goggles, gloves, long sleeves of cotton or
leather (do not wear any synthetic clothing) and respirator (if required by salt choice).
Turn on Any Ventilation Systems
If you are using salts that require ventilation or are using a ventilation system for general purpose, turn it on now.
Power Up the TAP Control
Power up the TAP control by throwing the control power switch located on the top rear of the control panel. The TAP control will illuminate, initialize and then go to
its Home Screen.
Develop or choose your proper, existing heat treat program that matches your intended use and salts. We recommend that you review the intended program via the
Schedule Summary function prior to starting. This gives you the opportunity to examine the firing data for correctness prior to committing to the process. When
developing a heat treat program we recommend that you not create any heating rates faster than 1000°F per hour. Heating too quickly can cause pressure to build
within the pot and lead to an eruption. See cautions section for details.
The Schedule Summary Function Allows You to Verify the Firing Data Prior to Committing to the Process
Note that the sample program shown above uses a heating rate (Ramp Rate) of 500°F/hr.
We Highly Recommend that You View the Intended Firing Data Prior to Use
Verify Chamber Thermocouple Position
Verify that the Chamber Thermocouple is fully inserted into the firing chamber. You may elect to have it contact the salt pot or not. If not, we recommend pulling it
away from the pot no more than 1/2”.
Start the Heat Treat Process
Once you have developed or chosen a heat treat program, and have verified its firing data, press the Start key on the TAP control to begin the heating process. When
a heat treat program is started the TAP control will always control from the Chamber Thermocouple. You do have the opportunity to switch it to the Immersion
Thermocouple once the salts become molten.
