How do you calculate machine efficiency of a welder?

To calculate the machine efficiency of a welder, divide the actual output or work produced by the welder (measured in units such as welds completed or weight of welded material) by the input energy consumed (typically measured in kilowatt-hours or similar units). Multiply the result by 100 to express it as a percentage. The formula is:

[ \text{Efficiency} (%) = \left( \frac{\text{Actual Output}}{\text{Input Energy}} \right) \times 100 ]

This calculation provides insight into how effectively the welder converts energy into productive work.
