10.3.9
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 work piece is directly clamped
to the output
of the unit.
Check for a small burn mark on the work piece. If the mark is not there,
replace the
pilot arc board.
Lift height is too high or plunge depth (stick-out) is too much. Perform
a lift test by
pressing the gun against an insulated surface. Air lift test
will not fully test the lift
capability of the welder gun coil circuit.
