Gas Purge
Pressing the Gas Purge rocker switch turns on the gas
solenoid for as long as the gas purge switch is held.
When the user interface is mounted in a separate control
box, gas purge may be active by the rocker switch on
the side of the feeder or the rocker switch on the side of
the control box.
The power source output remains OFF during Gas
Purge.
Gouging Kit Operation
The gouging kit provides a method to switch between
wire welding processes and a gouging process. The
electrode power path is automatically routed through the
wire feeder based upon the weld mode selected. FCAW
and GMAW modes route the power to the wire drive;
CAG modes route power to the gouging stud.
When in the gouging mode, the output to the power
source is turned ON and the gouging output stud will be
at electrode potential. Actual voltage and amperage are
displayed on the user interface.
Changing from a weld mode to gouging, or gouging to
welding may not be done while actively welding or
gouging.
When 2 single wire drives, both with a gouging kit, are
connected to one user interface, only one gouging stud
may be active at a time. To switch from gouging from
wire drive 1 to wire drive 2, first place wire drive 1 into a
welding mode. Then place wire drive 2 into a gouging
mode and active the output.
Dual Procedure and Memory Operation
The Dual Procedure and Memory buttons perform three
functions:
Weld procedure selection
Memory save and recall
Limits setting
There are two procedure memories (A and B) and 8 user
memories on single feeders and 16 user memories on
dual feeders. Additional memories are available through
the USB port.
Procedure Memory vs. User Memory
Procedure memory is used while welding. Changes to
the weld procedure (WFS, voltage, arc control, etc.)
immediately change the contents inside the selected
procedure memory.
User memories work by copying the weld procedure
from one of the six memories into either the A or B
procedure. Weld procedures are saved into the
memories only when the operator chooses.

Using Procedure Memories
Procedure memories can be selected by choosing either
"A" or "B" procedure directly with the memory panel, or
by selecting "GUN" and using a dual procedure gun to
select between procedure "A" and "B". When selecting
procedures with the gun switch, "A" or "B" will flash to
show which procedure is active.

User Memories
Recall a memory with memory buttons
To recall a user memory, press one of the six user
memory buttons. The memory is recalled when the
button is released. Do not hold the button for more than
two seconds when recalling a user memory.
Recall a memory with the gun trigger.
If desired, memories 2 through 8 can be recalled with the
gun trigger. For example, to recall memory 3, quickly pull
and release the gun trigger 3 times without welding.
Note: the Power Feed 84 is factory set with this feature
disabled. Use the SETUP menu and change P.4 to
enable memory recall with the gun trigger.
Save a memory with memory buttons.
To save a memory, press and hold the desired memory
button for two seconds. When the button is initially
pressed, the corresponding LED will illuminate. After two
seconds, the LED will turn off. Do not hold the button for
more than 5 seconds when saving a user memory.
Note that memories may be locked in the set-up menu to
prevent accidental overwrite of the memories. If an
