When not welding, the RANGER 305G engine will
be at the low idle speed. If you are using an LN-25
with an internal contactor, the electrode is not
energized until the gun trigger is closed.
8. When the gun trigger is closed, the current sens-
ing circuit will cause the RANGER 305G engine to
go to the high idle speed, the wire will begin to
feed and the welding process started. When weld-
ing is stopped, the engine will revert to low idle
speed after approximately 12 seconds unless
welding is resumed.
CAUTION
If you are using an LN-25 without an internal con-
tactor, the electrode will be energized when the
RANGER 305G is started.
