Stud welding unit N800i
As of 24.08.2021
Manual part number: BE 1227
129
10.3.17
E017 Warning - Pilot Blew 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:
During the pilot arc stage, the gun lifted as expected. The arc voltage
whould be
within a window of 12V and 60V (typically 30-40V). This error is generated if the arc
voltage exceeds 60V, representing a condition
where the pilot arc blew out.
For this condition, check surface conditions and clean the work piece
of any ferrule
dust or debris.
10.3.18
E018 Warning - Drop Time is too long for Short Cycle
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:
The Configuration of the drop time (F31) and the front panel time make
it such that the
pilot arc supply must be on for more that 40ms. The Maximum time the pilot arc will
stay on is 40ms, so it is possible the arc
will go out before the main arc starts. For
consistent welds, reconfigure
the drop time and\or front panel time to satisfy the
equation.
