INSTALLATION
RANGER 3 PHASE
A-4
ANGLE OF OPERATION
Internal combustion engines are designed to run in a
level condition which is where the optimum perfor-
mance is achieved. The maximum angle of operation
for the engine is 15 degrees from horizontal in any
direction. If the engine is to be operated at an angle,
provisions must be made for checking and maintain-
ing the oil at the normal (FULL) oil capacity in the
crankcase in a level condition.
When operating at an angle, the effective fuel capaci-
ty will be slightly less than the specified 9 gallons (34
Liters).
LIFTING
The RANGER 3 PHASE weighs approximately 575
lbs.(261kg) with a full tank of gasoline. A lift bail is
mounted to the machine and should always be used
when lifting the machine.
HIGH ALTITUDE OPERATION
At higher altitudes, Welder output de-rating may be neces-
sary. For maximum rating, de-rate the welder output 3.5%
for every 1000ft. (305m) above 3000ft. (914m).
If operation will consistently be at altitudes above 5,000 ft.
(1525m), a carburetor jet designed for high altitudes should
be installed. This will result in better fuel economy, cleaner
exhaust and longer spark plug life. It will not give increased
power. Contact your local authorized engine service shop
for high altitude jet kits that are available from the engine
manufacturer.
Do not operate with a high altitude jet installed at alti-
tudes below 5000 ft. This will result in the engine run-
ning too lean and result in higher engine operating
temperatures which can shorten engine life.

Muffler Relocation
•
Shut off welder and allow muffler to cool before
touching muffler.
------------------------------------------------------------------------
The RANGER 3 PHASE is shipped with the exhaust
coming out on the left side. The exhaust can be
changed to the opposite side by removing the two
screws that hold the exhaust port cover in place and
installing the cover on the opposite side. (Operating
the RANGER 3 PHASE without the cover in place will
result in a higher noise level and no increase in
machine output.)
LOCATION / VENTILATION
The welder should be located to provide an unrestrict-
ed flow of clean, cool air to the cooling air inlets and to
avoid heated air coming out of the welder recirculating
back to the cooling air inlet. Also, locate the welder so
that engine exhaust fumes are properly vented to an
outside area.
STACKING
RANGER 3 PHASE machines cannot be stacked.
CONNECTION OF LINCOLN ELECTRIC
WIRE FEEDERS
Shut off welder before making any electrical
connections.
------------------------------------------------------------------------
WIRE FEED (CONSTANT VOLTAGE)
CONNECTION OF LN-15 ACROSS-THE-ARC WIRE
FEEDER
The LN-15 has an internal contactor and the electrode
is not energized until the gun trigger is closed. When
the gun trigger is closed the wire will begin to feed
and the welding process is started.
a. Shut the welder off.
b. Set the Polarity switch to the desired polarity,
either DC (-) or DC (+).
c. 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.
d. Set the “RANGE” switch to the “WIRE FEED-CV”
position
e. Place the Engine switch in the “Auto Idle” position.
f. Adjust the wire feed speed at the LN-15 and adjust
the welding voltage with the output “CONTROL” at
the welder.
Output “CONTROL” must be set above 3.
Note: LN-15 Control Cable model will not work with
the RANGER 3 PHASE.
