True Energy™ (and Duration) Report
If you are someone like a weld engineer analyzing welds made on power sources on your production floor,
you will find the True Energy™ report on the Weld Listing tab quite useful. True Energy™ is a Lincoln
Electric technology that uses the digital control system embedded in each Power Wave® power source to
measure and calculate the instantaneous amount of energy put into a weld. The energy is defined as:

The True Energy™ report shows both the True Energy™ and the total arc time for the welds made by the
power source(s) you have selected in the Asset Tree.
Figure 5.25 Weld Listing Report: True Energy™
The top half of the report is a graph that displays the True Energy™ put into each individual weld made by
the power source(s) selected in the Asset Tree. It also overlays the total arc time used to calculate the True
Energy™ for those welds.
The bottom half of the report is a tabular list of the data. On the right, the system also displays the criteria
used to generate the data. Table 5.17 explains the columns on this report in more detail.

Field Description
Start of Weld The Start of Weld column displays the date and specific time the Welding Power
Source began performing the weld.
If you want to see additional information about the individual weld, simply click
the underlined date and time. The system automatically generates a Weld
Detail report for that weld (page 5.30).
