5 OPERATION
Adjusting the knob for voltage affects the wire feed speed. For example, if the display shows
300 in/min and 20 V, an adjustment of the voltage to 24 V will result in an increase to
approximately 365 in/min. A change in arc voltage of 4 V will result in a change in wire speed
of 65 in/min. For a step by step guide to setting wire speed and voltage see the section
"Setting a Welding Procedure".
Voltage
In CC mode the knob for setting the voltage is used to adjust the voltage which in turn affects
the wire feed speed. See the "Wire feed speed" description above.
The knob for setting the voltage can also be used to set the power source output voltage
when the MobileFeed is set to CV with the remote voltage control option and a Warrior power
source is being used. The power source voltage is then read on the MobileFeed display for
wire feed speed and voltage.
Display for wire feed speed and voltage
The digital display shows the wire feed speed (in/min or m/min) and voltage. It also enables
the welder to preset wire feed speed and power source voltage.
Trigger lock switch
The trigger lock function is a variation of 4 stroke operation. If the trigger lock function is
turned on, the torch trigger can be released once the arc is established, the power
source/feeder will continue to weld until the trigger is pressed and released again, or the arc
established signal is lost by manually breaking the arc. The trigger will not be locked unless
the arc is established before the trigger is released.
Power switch
The power switch (0/I) on the front of the wire feeder starts the wire feeder when the feeder
is connected to the power source and the work piece. The power source must be turned on
with the contactor closed.
