quality, improper choice of Current Sensor or

19 if using PT2, PT5, PT10 or PT20 as Current Sensor, the control will
operate in PRIMARY PRESET-RANGE MONITORING mode. When the control operates in
this MONITORING mode, the control will only display the weld current after a weld but will
not compensate the current error. The value of CURRENT setting in the weld schedules should
be input as the percentage of maximum current output of the control.
8.2.3 SECONDARY AUTO-RANGE COMPENSATION OR MONITORING
MODE WITH ROGOWSKI COIL
In these modes, a learning-type setup process is required. With this learning-type setup process,
the control will record the current values of maximum output, and constant current compensation
will be based on this data. The learning-type setup process is described in Section 8.4. Normally
these modes are used only when the current range of control is unavailable.

In these modes, a learning-type setup process is required. With a learning-type setup process,
the control will record the current values of maximum output, and constant current compensation
