The Arc Furnace is a GregTech 5 machine used to recycle machines and components back into Ingots.
Like every electric machine in GregTech 5, the Arc Furnace comes in 5 variants, one for each voltage from Low to Insane.
The Arc Furnace works quickly, but consumes energy quickly. Most recipes take a few seconds at most, but consume 3 Amps current continuously; as such, the Arc Furnace can accept up to 7 Amps from cables to recharge itself. Thus, Arc Furnace has the highest energy consumption rate among all non-multiblock processing machines, and caution must be taken when connecting power to an Arc Furnace, as it can very easily burn up any Cables smaller than 8x.
The Arc Furnace consumes both EU and fluid Oxygen when it is working. The Oxygen consumption is proportional to the time required by a recipe. As Oxygen is required for operation, an Electrolyzer is required to operate an Arc Furnace.
The Arc Furnace's primary purpose is the recycling of unwanted machines, blocks, and components back into the ingots used to make them. Up to 4 different Ingots can be produced from any input item, so materials can still be lost when disassembling complex machines.
In certain cases, the original ingots are not returned. Wood, Rubber, and Plastic burn into Ashes, Copper is cooked into Annealed Copper, and very importantly, Iron is cooked into Wrought Iron. This Iron -> Wrought Iron conversion is extremely useful, as it is both faster and more energy efficient than cooking Iron Nuggets into Wrought Iron Nuggets, and Wrought Iron is a better metal both for tools and for Steel production.
