Can the metal smelting furnace be connected to 220 household power sources?
The low-voltage power supply is a three-phase 380V/220V system, 380V is the industrial voltage, and 220V is the household voltage. In the eyes of most people, metal smelting furnaces are high-power electrical equipment, which are generally used in industrial production and must be connected to a 380V power supply. Connecting to a 220V household power supply will definitely not work.
In fact, it is not the case. The small capacity melting furnace can be connected to a 220V power supply. The small melting furnace for jewelry equipment uses a single-phase 220V power supply with a power of 3.5kw-3.8kw and a maximum operating temperature of 1600℃, which is enough to melt gold, K gold, silver, copper, brass and their alloys. Therefore, small smelting with 220V power supply is very suitable for metal smelting in schools, laboratories, jewelry stores, research institutes, banks, and personal gold prospectors.
So, in addition to small smelting furnaces, can other metal smelting furnaces be connected to 220V power supply? Of course, smelting equipment below 5kg can be equipped with 220V power supply according to customer needs. But it is better to use 380V power supply, because 380V power supply is more stable than 220V power supply.
