This is M-tier(advanced subclass) machine!
The first and currently one alloying equipment in CL which uses current to heat and eventually melt conductive materials.
The primary use is to recycle scraps or to make alloys, but it is not as efficient for alloys due to enormous power consumption and associated dangers.
As in real world it supplies energy(joules) per unit of time(watts).
Production rates are calculated by target heat and speed of heating using applied energy.
The more matter it contains the more energy it can accumulate. Different elements and compound have different values of Cp, but it is assumed one item is 1/9 of 1 standard minecraft volume(1m^3).
To calculate heat capacity of mixture(alloy) sum them up.
That way it goes to:
EAF can easily drain all the power from network if left unattended. It might be dangerous if your entire power grid is not isolated.
Overheating might results in destruction of arc furnace internal lining and containment vessel leading to a disastrous spillage and structural collapse.
It is generally a bad idea to perform chemical reactions in Arc Furnace vessel
