What this really means
Fatal – meaning you
have to power down
to reset. Otherwise,
you weld again to
reset.
Likely problem
E005
REGULATION ERROR-
SHORT CIRCUIT-
COULDN’T CONT-
ROL CURRENT
The control sensed that the
current was more than 50%
high and the control is ap-
plying the minimum allo-
wable pulse width for 10ms.
Current sensor wiring or dead short circuit
-See troubleshooting-
E006
INPUT VOLTAGE TOO
HIGH
This happens if the capaci-
tor voltage exceeds 400V
due to capacitor imbalances.
This also happens on boot-
up if the voltage skyrockets
after closing relays.
x
Input voltage is too high
-See troubleshooting-
E007
INPUT VOLTAGE TO
LOW-FLIP SWITCH TO
CORRECT VOLTAGE
SETTING
On boot-up only, after clo-
sing the charge relay, the
caps have 10 seconds to get
the proper voltage.
x
Incorrect voltage setting or broken/bad V-
F signal from one or more switch boards.
-See troubleshooting-
E008
PRIMARY OVERCUR-
RENT ERROR
A primary overcurrent oc-
curred.
x
On-board control PCB failure
-See troubleshooting-
E009
COULD NOT ES-
TABLISH PILOT ARC
The gun did not lift within
the pilot arc period
Shorted gun control cable, mechanical bin-
ding of the gun, pilot arc pcb failure, or ex-
cessive contaminants on work surface.
-See troubleshooting-
E010
CAPACITOR VOL-
TAGE COULD NOT BE
READ
The sensed capacitor V-F si-
gnal is not within the ac-
ceptable bounds.
Check V-F signal from Switch Boards
