WFS Calibration

Measurements for adjusting the WFS calibration must be
made before entering the set-up menu.
On dual feeders, there is calibration value for each wire
drive.
Wire Feed Speed offset allows the operator to adjust
the speed of the WD drive rolls. The adjustment can
range from -5% to +5% of normal speed.
On dual-head Power Feed 84 Feeders, a different set-
ting can be used for each head. The operator will be
prompted to select which head to edit before the setting
can be changed.
The calibration factor is adjustable from 0.95 to 1.05.
Adjust the WFS calibration value in the set-up menu.
While in the set-up menu, adjust the calibration factor as
follows:
