8.3.8 E008 Primary Overcurrent Error
Fatal, meaning you have to power down to continue welding
>> Yes
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 a very high primary current is sensed (by means of the current
transformer sensors in the back of the unit near the fan plenum), the
control will quickly disable the output of the power section to prevent
damage. This should only happen due to internal failures.
Likely problems or items to check - in order from most likely to least
likely:
1. Replace the power output rectifier board.
2. Replace the switch boards (both).
3. Replace the FACS output SMPS boards.
8.3.9 E009 Could Not Establish Pilot Arc
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:
At the beginning of the weld, the pilot arc supply is turned on and the
gun is energized. The gun has 20ms to lift (usually lifts in 3ms) and to
draw a pilot arc. If no stud voltage is sensed after 20ms, it is assumed
that the gun didn't lift and the control throws this error. Note - If the gun
lifts and no arc exists, it will try to turn the main current on (and will end
up with an E004 because no arc exists).
If the error is consistent, check that the workpiece is directly clamped
to the output of the unit.
Check for a small burn mark on the workpiece. If the mark is not there,
replace the pilot arc board.
