Enter the arc current (amps) and voltage (volts) into the Calculator. The calculator will evaluate the Arc Line Loss. 

Arc Line Loss Formula



  • ALL is the Arc Line Loss (watts)
  • AC is the arc current (amps)
  • AV is the arc voltage (volts)

To calculate Arc Line Loss, multiply the arc current by the arc voltage.

How to Calculate Arc Line Loss?

The following steps outline how to calculate the Ac Line Loss.

  1. First, determine the arc current (amps). 
  2. Next, determine the arc voltage (volts). 
  3. Next, gather the formula from above = ALL = AC * AV.
  4. Finally, calculate the Arc Line Loss.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

arc current (amps) = 5

arc voltage (volts) = 9
