RECOMMENDED PROCESSES AND
EQUIPMENT
The Ranger ™ 9 can be used for AC/DC Stick welding
(CC), DC Semiautomatic wire feed welding (CV),
AC/DC Tig welding (CC), and also offers a 9,000 Watt
AC 115/230 Volt, 60 Hertz power generator.
STICK:
For AC/DC Stick welding, the range is 40-250 Amps.
There is a 100% duty cycle on all settings. The Output
selector covers six ranges with remote output control
for fine current adjustment. For use with a broad range
of AC and DC electrodes including Fleetweld ® 5P.
K702 Accessory Kit which includes:
• Electrode holder and cable
• Work clamp and cable
• Headshield
K857 Remote Control Kit is optional for remote current
control.
TIG:
AC and DC TIG welding can be done at all constant
current output settings.
• Magnum ™ TIG Torch
• Magnum Parts Kit and Argon gas
• K930-1 TIG Module
• K936-1 Control Cable
Optional:
* K939-1 TIG Module Docking Kit
* K963 Hand Amptrol TM
* K870 Foot Amptrol
* K814 Arc Start Switch
WIRE FEED:
For DC Semi-automatic wire feed welding, three con-
stant voltage wire feed welding settings are available
giving a range of 40-250 Amps at 100% duty cycle.
Excellent performance will be obtained with a broad
range of Innershield® and Outershield® electrodes
(FCAW). Excellent arc characteristics are available
with MIG (GMAW). An output contactor is provided for
optimum semiautomatic welding.
LN-25 (428 or K446) with K624-1 42 Volt Remote
Output Control Module - Requires K626-xx Control
Cable. Provides "cold" electrode until gun trigger is
pressed. Voltage control is at the feeder. K446 LN-25
includes gas solenoid.
OPERATION
LN-25 (K449) Includes internal contactor for across
the arc operation (no control cable). Provides "cold"
electrode until gun trigger is pressed. Includes gas
solenoid. K444-1 Remote Voltage Control Kit is
required for voltage control at the feeder.
LN-742 (K617-1 or K618-1) or LN-742H (K617-2 or
K618-2), requires K619-xx Input Cable Assembly.
Provides "cold" electrode until gun trigger is pressed.
Includes gas solenoid. K589-1 Remote Control Kit
connects to the LN-742 to provide remote voltage and
wire speed control or K857 Remote Voltage Control
Kit connects to the Ranger 9 for voltage control at the
feeder.
LN-7 (K521) or LN-7 GMA (K440), requires K584-xx
Input Cable Assembly. Provides "cold" electrode until
gun trigger is pressed. K440 LN-7 GMA included gas
solenoid. K857 Remote Voltage Control Kit is required
for voltage control at the feeder. Ranger 9 must be
operated at "HIGH" idle.
Magnum Gun is required for gas-shielded welding.
Innershield Gun is required for gas-less welding.
AUXILIARY POWER:
The auxiliary power is provided by a 9,000 Watt, AC
115/230 Volt, 60 Hertz generator. It will operate AC
power tools. It will also power a 1.5 HP motor (if start-
ed under no load). It is capable of lighting ninety 100
Watt incandescent bulbs, and can also be used for
standby emergency power.
All Ranger 9 machines have two 20 amp circuit break-
ers for 115V auxiliary receptacles and two 50 amp cir-
cuit breakers for 230V receptacles. All machines are
also CSA approved.
Welder Operation
Constant Current
Constant Voltage
• Maximum Open Circuit Voltage at 3700 RPM is 80 volts
• Duty Cycle: 100% for both welding and auxiliary power.
