Howdy guys,
I am at a critical stage in my manufacture of a new casting setup. My original pot was 10" in diameter and about 5.5" tall. The heating element is electrical, and I assume it’s a standard 8" stovetop element (that's what it looks like anyway).
For reasons beyond my control the new pot is 12" across and 5.5" high. I have a new electric element (8") rated at 2100 watts @ 240V. But, since I am using a 12" pot, I can actually fit three 6" elements each rated at about 1500-1700 Watts @ 240 volt. So, either one element at 2100 watts or three for a total of 4500 watts.
The way I am designing the base, I can swap out the elements if needed, but it will be a chore.
My question is, will the single 2100 watt 8" element be enough to bring the pot up to 650F as my old one did?
Is 2100 watts considered a lot of wattage for melting lead or is the 3 1500's overkill?
My current design (the 10" pot with single element) takes about 75 minutes to bring the lead to temperature (about 125lbs of melt). It's a big pot.
What do you all think? Single or three element?
