Stud welding unit N1500i
As of: Aug 12.2021
Manual part number: BE 1221
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.
Workpiece vibration sniffing out pilot arc.
