Enter the total wattage used by the welding machine and the operational hours into the calculator to determine the welding machine load.

The following equation is used to calculate a Welding Machine Load.

WML = P * T /1000
• Where WML is the Welding Machine Load (kWh)
• P is the power consumption of the welding machine (watts)
• T is the operational hours (hours)

To calculate a welding machine load, multiply the power consumption by the operational hours.

## What is a Welding Machine Load?

Definition:

A Welding Machine Load is a measure of the total electricity used by a welding machine during a given period.

## How to calculate Welding Machine Load?

Example Problem:

The following example outlines how to calculate a Welding Machine Load.

First, determine the wattage of the welding machine. In this case, the welding machine is rated for a wattage of 4000 watts.

Next, determine the operational hours. This welding machine runs 8 hours per day.

Finally, calculate the Welding Machine Load using the formula above:

WML = P * T /1000

WML = 4000 * 8 /1000

WML = 32 kWh
