5.Installation Requirements:
1.Indoor Installation: The equipment must be installed indoors, with an ambient temperature range of 0°C to 40°C. The indoor environment must be free of flammable gases, corrosive gases, and steam.
2.Space Requirements:
Floor area of at least 5 square meters.
Working space length of at least 2.5 meters, width of at least 2 meters, and height of at least 3 meters.
The foundation must be sturdy and level.
3.Power Supply:
The furnace requires a dedicated three-phase, five-wire AC power supply: 380±10% V, 50±2% Hz.
Large power-consuming equipment such as welding machines, electric furnaces, and metal-cutting machines should not be connected to the same power distribution line.
4.Grounding: The equipment must be reliably grounded.
5.Gas Pressure: The inlet gas pressure should be 0.2 to 0.4 MPa.
