RECOMMENDED APPLICATIONS

WELDER

The RANGER 9 provides excellent constant current
AC/DC welding output for stick (SMAW) welding and
for TIG welding, and it offers constant voltage output
for DC semiautomatic wire feed welding. For more
details on using the machine as a welder, see WELD-
ING OPERATION in the Operation section of this
manual.

GENERATOR

The RANGER 9 gives AC generator output for medium
use demands. For more details on operating the gen-
erator, see AUXILIARY POWER in the Operation sec-
tion of this manual.
OPERATIONAL FEATURES AND
CONTROLS
The RANGER 9 was designed for simplicity. There-
fore, it has very few operating controls. Three switch-
es are used for welding operations:
• A nine-position output range selector switch selects
current output for constant current stick or TIG
applications and constant voltage wire feed appli-
cations.
• A fine output control switch for fine adjustment of
current or voltage within the selected output range
• A three-position polarity switch for selecting DC+,
DC- or AC welding output.
• A two-position toggle switch for selecting between
CONTROL AT WELDER or REMOTE CONTROL
(Remote control connections are made at either the
6 pin or the 14 pin amphenol connector.
• A two-position toggle switch for selecting between
control of the output contactor by the RANGER 9
(WELDING TERMINALS ALWAYS ON) or control of
the output contactor by a cable from a wire feeder
gun (WELDING TERMINALS REMOTELY CON-
TROLLED).
The gasoline engine control is a three-position toggle
switch for START, RUN, and STOP and a two-position
"IDLER" switch that selects engine speed for welding
or auxiliary power applications. See ENGINE OPERA-
TION in the Operation section of this manual for
details about starting, running, stopping, and breaking
in the gasoline engine.
RANGER 9
OPERATION
DESIGN FEATURES AND
ADVANTAGES
• 9,000 watts of auxiliary power
• Enhanced constant voltage capability with low (12-
21 volts), medium (15-27 volts), and high (18-35
volts) range settings for greater control of wire feed
applications.
• Built-in contactor with front panel selection of
"cold" or "hot" welding terminals: Cold (WELDING
TERMINALS REMOTELY CONTROLLED) – Closing
wire feeder trigger switch or amptrol causes con-
tactor to close and engine to accelerate to high idle.
Hot (WELDING TERMINALS ALWAYS ON) – The
contactor is closed and welding begins when elec-
trode touches work; engine automatically goes to
high idle.
• Constant current AC/DC Stick welding (SMAW)
process capability with output range from 40-250
amps (AC) or 40-250 amps (DC).
• Constant voltage DC Semiautomatic Wire Feed
Welding with output range from 40-250 amps.
• Constant current AC/DC TIG Welding with output
across the entire range of settings.
• Polarity switch for selecting DC+, DC-, or AC weld-
ing output.
• Separate ground stud for safe connection of case to
earth ground.
• Single 50 amp, 230 volt, full 9 kVA auxiliary power
receptacle.
• Double duplex 20 amp, 115 volt auxiliary power
receptacles.
• Electric starting.
• Battery Charging Ammeter.
• Engine Hour Meter for determining periodic mainte-
nance.
• Top-of-the-line 18 HP Onan P218 Performer
engine.
• Durable, heavy-gauge steel case.
• Built-in feet for easy mounting to truck bed or trailer.
• Bottom-mounted 10 gallon (38.0 litre) fuel tank with
convenient top fill and fuel gauge.
