How to calculate arc time percentage
This calculator finds arc time percentage — sometimes called duty cycle — by measuring the change from a starting to an ending value, commonly used in welding to track how much of total work time is actual arc-on welding time.
How the calculation works
Result = Starting value − Ending value. In an arc-time context, this typically represents a change in cumulative arc-on time or a related tracked metric between two checkpoints.
Example
A starting cumulative arc time reading of 145 minutes and an ending reading of 210 minutes: Result = 210 − 145 = 65 minutes of arc time in that interval (note: check field order in your specific use case, since which value is 'starting' vs 'ending' affects sign).
Frequently asked questions
How is Duty cycle calculated?
Duty cycle = ([Arc-on time] ÷ [Total working time]) × 100.

Pro Tips for Arc Time Percentage
- Track arc-on time against total shift time to calculate a duty cycle percentage, which is a common productivity metric in welding operations.
- Consistent, frequent tracking intervals (e.g., per shift) make trends easier to spot than infrequent, irregular measurements.
Common Arc Time Percentage Mistakes to Avoid
- Mixing up which reading is the starting point and which is the ending point, which flips the sign of the result.
