As a troubleshooter aid, error code information will now persist on the user interface displays even after the fault
is cleared. When a fault occurs that the user interface needs to display, welding will be inhibited for 5 seconds. If
the fault has cleared, the error code information can then be removed from the displays by pressing the Reset
button, by changing a user interface control or by starting a new weld.
The following is a list of possible error codes that the Power Feed
™
10M Dual Wire Feeder can output via the dis-
play on this user interface.
%AF7For any Err # listed below write down the error number for reference and try cycling power to see if the
error clears itself. If not, refer to the What to Do column for the given Err.

Thermal error
Softstart error
Secondary overcurrent error
Capacitor delta error
Excess voltage on the main capaci-
tors. May be caused by improper
input configuration.
When accompanied by an undervolt-
age error on the same side, it indi-
cates no capacitor voltage present
on that side, and is usually the result
of an open or short in the primary
side of the machine.
Indicates over temperature. Usually
accompanied by Thermal LED.
Check fan operation. Be sure
process does not exceed duty cycle
limit of the machine.
Capacitor precharge failed. Usually
accompanied by codes 32-35.
The secondary (weld) current limit
has been exceeded. When this
occurs the machine output will
phase back to 100 amps, typically
resulting in a condition referred to as
"noodle welding"
NOTE: For the Power Wave 455/R
the secondary limit is 570 amps for
the standard stud, and 325 amps for
the STT stud and all single phase
operation.
The maximum voltage difference
between the main capacitors has
been exceeded. May be accompa-
nied by errors 32-35.
