It carries a 50% higher {{infoicon|Worker|ui-yes}} and a 83% higher {{infoicon|Electricity}} requirement in addition to {{infoicon|Water}}, some of which can be recovered by passing the byproduct {{infoicon|Steam Lo}} through [[Cooling Tower]]s. In exchange, it doubles throughput of {{infoicon|Silicon (Poly)|text=Silicon}} smelting without increasing the need for {{infoicon|Coal}} or {{infoicon|Graphite}}. <br /> <br /> Additionally, it incorporates smelting recipes for {{infoicon|Iron Ore Crushed}}, {{infoicon|Copper Ore Crushed}}, and {{infoicon|Glass Mix}} similar to those available in the [[Blast Furnace II]] which make it possible to replace all Blast Furnace II machines on the island. These recipes switch 15 Coal for 6 Water and 3 Graphite (plus 4 Tflop and 5.5 MW power consumption), whilst generating 6 Steam Lo and reducing {{infoicon|Exhaust}} output by 24/min. Assuming that all Graphite is made from Coal and {{infoicon|Chlorine}}, this amounts to a 90% reduction in Coal usage.<br /> <br /> While {{variants|Nuclear Reactor}} or {{variants|Solar Panel}}, are strongly recommended for powering the Arc Furnace II, [[Boiler (Coal)]] is still a viable option. Even with coal power, overall Coal usage still drops by 16.7-25.0% relative to a Blast Furnace II, depending on how efficiently the {{infoicon|Steam Lo}} byproduct is used. Similarly, Exhaust drops by 2.0-4.5 per furnace.<br /> <br /> {{Footer Infobox}}</div>
