When using the EN1001 Control in CONSTANT CURRENT mode, both AUTOMATIC
POWER FACTOR and CONSTANT CURRENT function will compensate current. When
the control operates under poor power factor and low PERCENT CURRENT output situation,
the MANUAL POWER FACTOR should be set to 99% (

The EN1000/EN1001 Control is in the AUTOMATIC POWER FACTOR mode when shipped
from the factory. Calibration of the automatic power factor circuit is not required. This has two
benefits:
1. It is not necessary to make manual adjustments when installing the control, to match its
circuitry to the POWER FACTOR of the welding machine;
2. It assures that maximum welding current, for any welding transformer tap switch setting,
will occur when the selected PERCENT CURRENT is 99%.
If desired, for some applications, the AUTOMATIC mode can be disabled and the machine
POWER FACTOR can be set manually (see Section 5.4.10). Machine’s POWER FACTOR can
be determined when in the AUTOMATIC POWER FACTOR mode as follows:
1. Use SELECT to find

3. Make a weld.
At this point, after the weld is complete, the machine’s POWER FACTOR will be shown in the
DATA display (see Section 5.4.10).
When measuring the POWER FACTOR, the displayed POWER FACTOR corresponds to the
last weld made by the control.
