A-6
Connection of the LN-7 to the Ranger 8
• Shut the welder off.
• Connect the LN-7 and the K240 contactor kit per
instructions on the connection diagram S17742
(can be found in the back of this manual).
• Place the “RANGE” switch to the “WIRE FEED”
position and the “POLARITY” switch to the
desired polarity.
• Place the “IDLER” switch in the “HIGH” idle
position. The engine idling device may not
function when welding in the “WIRE FEED” mode.
• Adjust wire feed speed at the LN-7 and adjust the
welding voltage with the output “CONTROL” at
the welder.
NOTE: If the output “CONTROL” is set below “3” the
K240 contactor may not pull in.
Connection of K930-[ ] TIG Module to the
Ranger 8.
The TIG Module is an accessory that provides high
frequency and shielding gas control for AC and DC
GTAW (TIG) welding. See IM528 supplied with the
TIG Module for installation instructions.
Note: The TIG Module does not require the use of a
high frequency bypass capacitor. However, if the
Ranger 8 is used with any other high frequency equip-
ment, the bypass capacitor must be installed - order
kit T12246.
INSTRUCTIONS
Additional Safety Precautions
Always operate the welder with the roof and case
sides in place as this provides maximum protection
from moving parts and assures proper cooling air
flow.
Read and understand all Safety Precautions before
operating this machine. Always follow these and any
other safety procedures included in this manual and in
the Engine Owner’s Manual.
Welder Operation
Welder Output
• Maximum Open Circuit Voltage at 3700 RPM is
80 Volts RMS.
• Duty Cycle: 100% for both welding and auxiliary
power.
Auxiliary Power
The Ranger 8 can provide up to 8,000 watts of
115/230 volts AC, single phase 60Hz power for con-
tinuous use. The front of the machine includes three
receptacles for connecting the AC power plugs; one
50 amp 115/230 volt NEMA 14-50R receptacle and
two 20 amp 115 volt NEMA 5-20R receptacles.The
CSA machine has one 50 amp 115/230 volt NEMA
14-50R receptacle and two 15 amp 115 volt NEMA 5-
15R receptacles.
Do not connect any plugs that connect to the power
receptacles in parallel.
------------------------------------------------------------------------
Start the engine and set the “IDLER” control switch to
the desired operating mode. Set the “CONTROL” to
10. Voltage is now correct at the receptacles for auxil-
iary power.
115/230 Volt Dual Voltage Receptacle
The 115/230 volt receptacle can supply up to 35 amps
of 230 volt power to a two wire circuit, up to 35 amps
of 115 volts power from each side of a three wire cir-
cuit (up to 70 amps total). Do not connect the 115 volt
circuits in parallel. Current sensing for the automatic
idle feature is only in one leg of the three wire circuit
as shown in the following colunm.
Ranger 8
Constant Current 225 Amps AC @ 25 Volts
210 Amps DC @ 25 Volts
Constant Voltage 200 Amps DC @ 20 Volts
