8.3.3 E003 Capacitor Voltage Imbalance
Fatal, meaning you have to power down to continue welding
>> No
Acknowledge, meaning the error will exist as long as the unit
is powered on. (Note, welding can continue while the error
exists)
>> No
Description:
When (and only when) running the unit on the high range 400, the
primary capacitor bank has the potential to go out of balance such that
they are not the same voltage. When they are >20VDC out of balance
for 10ms, the weld will be aborted to protect the power unit. When
operating the unit with very low current and/or very short cable load,
unit will have the most opportunity for this imbalance. Use F18 and the
lower up\down arrows to check left and right voltages.
Likely problems or items to check - in order from most likely to least
likely:
•
Try reducing F2, which gives the most opportunity for
delivering current through a minimal load.
•
Confirm by multi-meter that each switch board is truly out of
balance. If not out of balance, replace switch board(s)
8.3.4 E004 Regulation Error-Arc Went Out
Fatal, meaning you have to power down to continue welding
>> No
Acknowledge, meaning the error will exist as long as the unit
is powered on. (Note, welding can continue while the error
exists)
>> No
Description:
If the FACS output SMPS board senses that the current was more than
50% lower than the set point while the control to the power system was
at the maximum output for >15ms, it will abort the weld and display this
error. This will happen if the current sensing fails for any reason (wiring,
power supply, etc.), but is most likely caused by the arc actually
popping out.
