middle of the screen.
Weld limits, if any, and the peak weld current
monitor results for the last weld completed are

The CD-A125A allows programmed values for
Energy in tenths of watt seconds for energy
settings between 1.0 and 10.0 Ws. The energy
settings for the CD-A125A between 10 and 125
Ws can
only
be set in whole number increments.
