Calculating the Power Consumption of Welding MachinesInverter 4.314(kW)------0.89 efficiency
In general, the power consumption of a welding machine is calculated by multiplying the operational hours by the wattage of the welding machine. For example, let’s take a welding machine that supplies 160AMP at 24V with, let’s say 0.89 efficiencies, and has a rated power of 4.3kW. If this machine is used for 30 minutes, the total power consumption will be 2.15 kWh.
A welding machine’s rated power can be calculated using the output voltage and the output current the welding machine supplies. Here, the rate at which the device consumes power is called watt, and the actual power consumption is called kilowatt per hour. For example, if your machine is rated as 1 kW and you use it for 2 hours, the machine will consume 2 kW.
Let’s go again to the previous example. I mentioned a welding machine that supplies 160 AMP current at 24V with 0.89 efficiency. In order to calculate the rated power of this welding machine, you need to use this formula:
Power (kW) = (Output Voltage X Output Current) / Efficiency
Now let me use the values of the previously mentioned welding machine.
Power (kW) = (24 X 160) / 0.89 = 4.314 kW.
So the rated output power is 4.314 kW in one hour.
