15 Calibration Function of Welding Current
15.1 Overview of the Welding Current Calibration Function
The welding current command value may be different from the actual welding current if the
wire extension is out of standard value, the welding voltage command value is set entirely
different from the synergic voltage which is specified as 100 % and Yaskawa deems to be
adequate, or the P parameter value is changed.
The calibration function of welding current allows the actual welding current value to check
against the welding current command by adjusting the wire feeding amount corresponding to
the welding current command.
When the calibration function of welding current is set to "enabled" (The set values of P62
NOTE
and P63 are other than 100), be sure to record the parameter values of:
-C parameter (C13 to C18) and;
-P parameter of each user file (P62 and P63).
If parameters were initialized, input the recorded parameter contents directly.
Set the parameters P62 and P63 to "100" again to disable the calibration function of weld-
ing current.
For welding current calibration of MOTOWELD-EH500, adjust the wire feeding speed based
on the welding current commands at 2 points

Be sure to set the welding current command value of current calibration 2 is higher than
that of current calibration 1.
