Lincoln Electric IM893 RANGER 305 D (CE) - Manual (Page 16)

A-4 INSTALLATION
RANGER 305D (CE)
A-4
NOTE: This machine is furnished with a wet charged
battery; if unused for several months, the battery may
require a booster charge. Be careful to charge the bat-
tery with the correct polarity.
MUFFLER OUTLET / SPARK ARRESTOR
In addition to operating as a Spark Arrestor the Spark
Arrestor serves as an outlet cover for the muffler as
well as providing additional sound reduction. Remove
from the box and install using the clamp and instruc-
tions provided.
An incorrect spark arrestor may lead to damage to
the engine or adversely affect performance.
------------------------------------------------------------------------
REMOTE CONTROL
The machine is equipped with a 6-pin and a 14-pin
connector. The 6-pin connector is for connecting the
K857 or K857-1 Remote Control or for TIG welding,
the K870 foot Amptrol or the K963-3 hand Amptrol.
When in the CC-STICK, DOWNHILL PIPE, or CV-
WIRE modes and when a remote control is connected
to the 6-pin Connector, the auto-sensing circuit auto-
matically switches the OUTPUT control from control at
the welder to remote control.
When in TOUCH START TIG mode and when a
Amptrol is connected to the 6-Pin Connector, the
OUTPUT dial is used to set the maximum current
range of the CURRENT CONTROL of the Amptrol.
The 14-pin connector is used to directly connect a
wire feeder control cable. In the CV-WIRE mode,
when the control cable is connected to the 14-pin con-
nector, the auto-sensing circuit automatically makes
the Output Control inactive and the wire feeder volt-
age control active
NOTE: When a wire feeder with a built in welding
voltage control is connected to the 14-pin connec-
tor, do not connect anything to the 6-pin connec-
tor.

ELECTRICAL CONNECTIONS
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.
• Be double insulated.
• Do not ground the machine to a pipe that carries
explosive 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 connect-
ed between the machine grounding stud and the
frame of the vehicle. When this engine driven welder
is connected to premises wiring such as that in a
home or shop, its frame must be connected to the sys-
tem earth ground. See further connection instructions
in the section entitled "Standby Power Connections" .
In general, if the machine is to be grounded, it should
be connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into the
ground for at least ten feet and having no insulated
joints, or to the metal framework of a building which
has been effectively grounded.
A machine grounding stud marked with the symbol
is provided on the front of the welder.
WELDING TERMINALS
The machine is equipped with a toggle switch for
selecting "hot" welding terminal when in the "WELD
TERMINALS ON" position or "cold" welding terminal
when in the "REMOTE" position.
WELDING OUTPUT CABLES
With the engine off connect the electrode and work
cables to the output studs. The welding process dic-
tates the polarity of the electrode cable. These con-
nections should be checked periodically and tightened
with a 19mm wrench.
Table A.1 lists recommended cable sizes and lengths
for rated current and duty cycle. Length refers to the
distance from the welder to the work and back to the
welder. Cable diameters are increased for long cable
lengths to reduce voltage drops.
