Wire feed speed (Arc voltage control)
The wire feed speed is controlled by the knob for wire feed speed on the front of the wire
feeder.
When the wire feeder is connected to a constant voltage (CV) type of power source, the knob
for wire feed speed controls the welding current. Turning the knob clockwise increases the
welding current; turning it counterclockwise decreases the welding current.
When the wire feeder is connected to a constant current (CC) type of power source, the knob
for wire feed speed controls the arc voltage. Turning the knob clockwise decreases the arc
voltage; turning it counterclockwise increases the arc voltage. The actual wire feed speed for
any given setting varies with the arc voltage. Increasing the arc voltage causes an increase
in the wire feed speed.
When the CV/CC switch inside the MobileFeed is set to CV, the "preset" wire feed speed will
be shown on the display. The wire speed will not vary with changes in the arc voltage.
When the CV/CC switch is set to CC, the wire feed speed and voltage will be shown on the
display. The wire speed shown is the speed that will result from the displayed voltage.
