AUXILIARY POWER
The Ranger 300 can provide up to 12,000 watts of
120/240 volts AC, single-phase 60 HZ power for con-
tinuous use. The front of the machine includes three
receptacles for connecting AC power plugs, one 50
amp 120/240 V NEMA 14-50R receptacle and two 15
amp 120 V 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 aux-
iliary power.
Most single-phase motors through 2.0 HP can be
started if there is no load on the motor or other load
connected to the machine. Since the full load current
of a 2.0 HP motor is typically 18 to 20 amps when
operated at 120 V or 9 to 11 amps when operated at
240 V, it should be connected to the 120/240 dual volt-
age receptacle. The full load current of a 1.5 HP motor
is typically 15 to 17 amps when operated at 120 V or
7.5 to 8.5 amps when operated at 240 V. It also should
be connected to the 120/240 dual voltage receptacle.
A 1.0 HP motor that draws less than 15 amps at 120 V
can be plugged into one of the 120 V duplex recepta-
cles.
SIMULTANEOUS WELDING AND
POWER LOADS
Auxiliary power ratings are with no welding load.
Simultaneous welding and power loads are permitted
by the following table. The permissible currents shown
assume that current is being drawn from either the
120 V or 240 V supply (not both at the same time).

(OUTPUT CONTROL SET AT 10)
NOTE: Voltage and permissible watts decrease as “CONTROL” is adjusted to settings less than 10. It is recommended
that at settings less than 10, only incandescent lighting loads be connected to the auxiliary power receptacles.
