Most 1.5 HP motors can be started if there is no load
on the motor or other load connected to the machine,
since the full load current rating of a 1.5HP motor is
approximately 20 amperes (10 amperes for 230 volt
motors). The motor may be run at full load when
plugged into only one side of the duplex receptacle.
Larger motors through 2HP can be run provided the
receptacle rating as previously stated is not exceeded.
This may necessitate 230V operation only.
It must be noted that the above 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 115 volt or 230 volt supply
(not both at the same time).
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.

Standby Power Connections
The Ranger 9 is suitable for temporary, standby or
emergency power using the engine manufacturer's
recommended maintenance schedule.
The Ranger 9 can be permanently installed as a
standby power unit for 230 volt, 3-wire, 40 ampere
service. Connections must be made by a licensed
electrician who can determine how the 115/230 volt
power can be adapted to the particular installation and
comply with all applicable electrical codes. The
following information can be used as a guide by the
electrician for most applications (refer also to the
Premises Wiring diagram shown).
IMPORTANT: When the Ranger 9 is connected to
a 230 volt, 3-wire line, the unit should be operated
with the idler switch in the “HIGH” idle position to avoid
load sensing problems. If the machine is set for
automatic idle, the 230 volt circuit will sense loads and
cause the engine to accelerate to high idle. However,
since only one line of the circuit senses current, 115
volt power drawn from only one line to neutral may
result in the engine not going to high idle.
1. Install the double pole, double throw switch
between the power company meter and the
premises disconnect.
Switch rating must be the same or greater
than the customer’s premises disconnect and
service overcurrent protection.
