Alternating green Non-recoverable system fault. If
the power source or wire feeder
status LED is flashing any combi-
nation of red and green, errors are
present in the system. Read the
error code before the machine is
turned off.

code is present, the codes will be
separated by a green light.
To clear the error, turn the power
source OFF, and then back ON to
reset. See troubleshooting sec-

4. DUAL ENCODERS – Accurately adjust weld parameters
as pre-set values, or on-the-fly values while welding.
5. SWITCH PANEL – Heavy-duty pushbutton switches that
control inching of the wire, starting and stopping of weld-
ing, travel and flux control. The Switch Panel can be
removed and turned into a remote pendant.
6. START – Activates the weld cycle.
7. STOP – Deactivates the weld cycle.
8. TRAVEL MODE:
ON – Activates travel.
OFF – Disables travel.
AUTO – Activates travel when the START
button is pressed. Disables travel when the
STOP button is pressed.
9. FLUX FILL – Activates the flux hopper.
10. INCH UP – Feeds the wire upwards, away from the
work.
11. INCH DOWN – Feeds the wire downward, toward the
work. NOTE: The Power Feed 10A includes an option in
the Setup Menu (P.15) to enable the touch sense circuit-
ry in the power source. Having this feature enabled will
stop the wire when it comes in contact with the work,
engaging the flux hopper on contact for automatic flux
fill. The flux hopper will disengage when the INCH
DOWN button is released.
• This “Hot Inch” feature enables the output. Avoid
touching any exposed parts as defined in the

12. MEMORY PANEL – Enables the storage and recall of
up to 6 weld schedules. Enables weld parameter limit
setting.

POWER-UP SEQUENCE
When power is first applied to the machine, a lamp test is
performed. All discrete LED’s are turned on, all 7-segment
displays will show a pattern of "8." and all alphanumeric dis-
plays will show a hatch pattern where every-other pixel is
illuminated. The lamp test will last for two seconds, after
which all displays are turned back off. The 16-character
alphanumeric display will show "Initializing…" while waiting
for the Weld Sequencer to configure. The Mode Select
Panel alphanumeric displays will then display the name of
the weld table loaded in the attached power source while
the user interface prepares the machine for operation. After
all initialization is complete, the Mode Select Panel will dis-
play the weld mode information for the mode number that
was selected when the machine was last powered down.
WIRE FEEDER SETUP
Use the INCH UP / INCH DOWN pushbottons to insert wire
into feed mechanism. Prior to inserting the wire, make sure
the Touch Sense option is disabled (P.15 in the Setup
Menu).
INCH WIRE FEED SPEED SETTING
While pressing either the Inch Up Pushbutton or the Inch
Down Pushbutton, the preset wire feed speed will be dis-
played on the Dual Display panel. This value can be
changed while inching wire by turning the WFS Encoder and
will be stored into memory.
