Welding Machine Amperage Formula
The following equation is used to calculate the Welding Machine Amperage.
A = P / V
- Where A is the welding machine amperage (amps)
- P is the power consumption/load (kW)
- V is the voltage (volts)
To calculate the welding machine amperage, divide the power consumption/load by the voltage.
What is a Welding Machine Amperage?
A welding machine amperage is the total current drawn by a welding machine during operation.
How to Calculate Welding Machine Amperage?
The following example outlines the steps and information needed to calculate Welding Machine Amperage.
First, determine the power consumption of the welding machine. For this example, using the help of the load calculator above, the power consumption is found to be 4,500 Watts.
Next, determine the voltage used for the welding machine. In this case, the voltage is standard 120 volts.
Finally, calculate the welding machine amperage using the formula above:
A = P / V
A = 4,500 / 120
A = 37.5 amps
