Stainless casting pot-a prototype

[marky123]

There's an 1100w stove ring under it.
0 to molten in 6 minutes!!!

Need more pic's and info. I like the triangle lead ingots look like mine made mold out of angle iron.

Nice, more pics and descriptions please.

Are you running it on 120 or 240 volts? I have been searching for a replacement element for my shotmaker, 120V and am finding them to be about non-existent.

Depending on how the element is n your shot maker an element for a 120 volt water heater might work. For around $15 they sell an element about 7' or 8 " long. I think they are 1800 watts. More than plenty.

You can use a 240V element on 120V. The power output will be about 1/4 of the rating. Stove burners were made with two 240V elements that were operated in series (120V) or parallel (240V) to have different heat levels.

I'm pretty sure it would give about 50% output.

I'm pretty sure it would give about 50% output.

If you decrease the voltage, you drop the efficiency.

From https://electrical-engineering-porta...ed-in-details: "The second formula for calculating resistive heating is:

P = I2 x R

where P is the power, I is the current, and R is the resistance. This equation could be derived from the first one by substituting I . R for V (according to Ohm’s law). This second formula is more frequently used in practice to calculate resistive heating, whereas the first formula has other, more general applications.

As we might infer from the equation, the units of watts also correspond to amperes2 x ohms (A2 x Ω). Thus, a current of one ampere flowing through a wire with one ohm resistance would heat this wire at a rate of one watt. Because the current is squared in the equation, two amperes through the same wire would heat it at a rate of 4 watts, and so on."

The efficiency does not change, all electric resistance heaters are practically 100% efficient. Cutting the voltage in half just reduces the energy input and output to 1/4 except that the resistance may change due to the lower temperature of the element and affect the output somewhat.

The original element is a stove burner type coil, nominally 6" dia. 1100W, 120Vfor whatever reason it heats up fine but after a short time it quits heating
