Hi Bill, Sorry its taken a bit. I measured the amperage today and it was 236V I'm not quite sure how to measure the resistance of the elements as when i did it I kept getting a number like 2.1 (that doesn't seam right especially since I found a hand written note indicating that the OHM tested in 1984 is 14.4 . Attached is also a picture of how they are connected and the writing. Thanks

Hi there, It works on a 20A, single phase, 220V, 2.2kW, 120L Thanks,

Thanks for your reply, that all makes perfect sense. Unfortunately the kiln doesn’t have an equipment tag. So I’ll try tracking down the person who rebuilt it. Do u know if there is another way to find out it’s rating should I not be able to track down them down?

I have a refurbished AFC kiln. The elements are running perfectly and I just replaced the thermocouple (type N). I was told it could reach 1280 periodically so assume 1220c wouldn’t be a problem. However, getting to cone 6 takes 17-18hrs. It’s manual so I do ramp rate of 100/hr till 1000c hold for soak 30mins then an just leave on full till cone 6. Once it hits about 1100 it won’t ramp more than 30c/hr and even less ramp after 1150. Essentially I’m soaking till the cone 6 goes down. Is this normal? I’m worried about ruining my elements with such a long firing and would like to cut this time down to 14/15hrs. It’s been suggested to either increase the insulation on the floor and back wall to see if it’ll hold more heat. And also or potentially replace my top elements with a lower resistance ones to supply more heat. any thoughts would be appreciated as I’m not sure what to do. TIA
