WARNING - NEAR MAXI-
MUM WELDING OUTPUT
CAPACITY
If the unit is delivering 95% of the maxi-
mum power capacity, it will display this
warning. It will not damage the unit to
operate at this level, but is intended to in-
form the user. If the output voltage is at
the maximum (due to long or small
cables, high lift), the actual current may
start to drop below the desired current.
This warning can be disabled using F54
Small weld cable, long weld cable

WARNING - DROP TIME IS
TOO LONG FOR SHORT CYC-
LE
The configurations of the drop time(F31)
and the front panel time make it such that
the pilot arc supply must be on for more
than 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
