How to use this tool

  1. Enter every input in the labeled units; use measured or independently specified properties.
  2. Check the stated model assumptions before calculating.
  3. Interpret the output as a model estimate and verify it independently for the intended application.

Try this example

{
  "voltage": 24,
  "current": 150,
  "travel": 5,
  "efficiency": 0.8
}

Accuracy and scope

Steady average values; pulsed processes need time-averaged instantaneous power. Not a welding procedure qualification. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
