REMOTE CONTROL

The RANGER 305D is equipped with both a 6-pin and
a 14-pin Amphenol connector. The 6-pin connector is
primarily used to connect a remote control device, such
as a K857, or a TIG Amptrol, such as the K870 or
K812. The 14-pin Amphenol connector is primarily
used to directly connect a wire feeder, TIG module, or
Spool Gun module control cable. See Accessories
section for more information.
NOTE: Both the 6-pin and 14-pin Amphenols share the
same output control auto-sensing and contactor circuit-
ry; for this reason, there can only be one device
plugged into the Ranger 305D at any time.
Switch operation is covered in "Operation" section.

ELECTRICAL OUTPUT CONNECTIONS

See Figure A.1 for the location of the 120 and 240 volt
receptacles, weld output terminals, and ground stud.
Output stud covers are provided on code 11275 and

MACHINE GROUNDING

Because this portable engine driven welder creates its
own power, it is not necessary to connect its frame to
an earth ground, unless the machine is connected to
premises wiring (home, shop, etc.)
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:
• Be grounded to the frame of the welder using a
grounded type plug or be double insulated.
WARNING
Do not ground this machine to a pipe that carries explo-
sive or combustible material.
When this welder is mounted on a truck or trailer, its
frame must be electrically bonded to the metal frame of
the vehicle. Use a #8 or larger copper wire connected
between the machine grounding stud and the frame of
the vehicle. When this engine driven welder is con-
nected to premises wiring such as that in a home or
shop, its frame must be connected to the system earth
ground. See further connection instructions in the sec-
tion entitled "Standby Power Connections" as well as
the article on grounding in the latest National Electrical
Code and the local code.
Note: Different models appearance
may vary slightly.
