1. AC Electrofusion Welding: commonly known as arc welding transformers, mainly BX1-500 and BX3-500 types; if welding with a current of 300A, the power consumption per hour is about 8.4 degrees (according to the efficiency of the welding machine is 80%, the utilization rate is 70%, Welding voltage 32V calculation);

2. Thyristor rectifier welding: ZX5-500; if welding with a current of 300A, the power consumption per hour is about 8.96 degrees (calculated based on the welding machine efficiency of 75%, the utilization rate of 70%, and the welding voltage of 32V);

3. Inverter welding machine: ZX7-500: If welding with a current of 300A, the power consumption per hour is about 7.47 degrees (calculated according to the welding machine efficiency of 90%, the utilization rate of 70%, and the welding voltage of 32V);
