Lincoln Electric IM813 RANGER 305 D (CE) - Manual (Page 18)

7. Set the "IDLE" switch to the "AUTO" position.
When not welding, the RANGER 305D (CE)
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 305D (CE)
engine to go to the high idle speed, the wire will
begin to feed and the welding process started.
When welding is stopped, the engine will revert to
low idle speed after approximately 12 seconds
unless welding is resumed.
If you are using an LN-25 without an internal con-
tactor, the electrode will be energized when the
RANGER 305D (CE) is started.

A-6 INSTALLATION
RANGER 305D (CE)
A-6
• Across-The-Arc Model:
Attach the single lead from the front of the LN-15 to
work using the spring clip at the end of the lead. This
is a control lead to supply current to the wire feeder
motor; it does not carry welding current.
Set the "WELD TERMINALS" switch to "WELD TER-
MINALS ON".
• Control Cable Model:
Connect Control Cable between Engine Welder and
Feeder.
Set the MODE switch to the "CV-WIRE " position.
Set the "WELD TERMINALS" switch to "REMOTELY
CONTROLLED".
Set the "WIRE FEEDER VOLTMETER" switch to
either "+" or "-" as required by the electrode polarity
being used.
Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
Set the "IDLE" switch to the "High" position.
Connection of the LN-25 to the RANGER 305D (CE)
Shut off welder before making any electrical con-
nections.
------------------------------------------------------------------------
The LN-25 with or without an internal contactor may be
used with the RANGER 305D (CE). See the appropri-
ate connection diagram in Section F.
NOTE: The LN-25 (K431) Remote Control Module and
(K432) Remote Cable are not recommended for use
with the RANGER 305D (CE).
1. Shut the welder off.
2. For electrode Positive, connect the electrode cable
from the LN-25 to the "+" terminal of the welder
and work cable to the "-" terminal of the welder. For
electrode Negative, connect the electrode cable
from the LN-25 to the "-" terminal of the welder and
work cable to the "+" terminal of the welder.
3. Attach the single lead from the front of the LN-25 to
