Estimate reading time: 2 minutes
I almost finished the oven for baking out nixie tubes.. I had to replace the heating element because the previous one melted 😀 The only thing I had to add is the fuse 😉
The oven will work up to 500°C, I plan to bake the tubes at temperature of 480°C. The limiting element is the temperature sensor, it is rated for 600°C. The PID controller (MyPin TA4) works to 1200°C, the fire-resistant board (white material) should work up to 1150°C. I limited the power to 200W, the oven goes to 450°C in 45 minutes.
If You are interested in details, just ask in comments..
As usually, I thanks to Ron for his patience and help with building that stuff!
The overall view of the vacuum system with the oven mounted..
PID controlled on the left, K-type thermocouple in the center (goes through the oven wall), SSR in the right upper corner and light dimmer used as a power controller.
