Lincoln Electric IM707 Commander 500 - Manual (Page 13)

A-5 INSTALLATION
COMMANDER 500 CUMMINS
A-5
The Commander is shipped with the negative battery
cable disconnected. Before you operate the machine,
make sure the Engine Switch is in the OFF position
and attach the disconnected cable securely to the neg-
ative (-) battery terminal.
Remove the insulating cap from the negative battery
terminal. Replace and tighten negative battery cable
terminal. NOTE: This machine is furnished with a wet
charged battery; if unused for several months, the bat-
tery may require a booster charge. Be sure to use the
correct polarity when charging the battery.
MUFFLER OUTLET PIPE
Remove the plastic plug covering the muffler outlet
tube. Using the clamp provided secure the outlet pipe
extension to the outlet tube. Install the rain cap on the
end of the outlet pipe extension.
SPARK ARRESTOR
Some federal, state or local laws may require that
gasoline or diesel engines be equipped with exhaust
spark arrestors when they are operated in certain loca-
tions where unarrested sparks may present a fire haz-
ard. The standard muffler included with this welder
does not qualify as a spark arrestor. When required by
local regulations, a suitable spark arrestor, must be
installed and properly maintained.
An incorrect arrestor may lead to damage to the
engine or adversely affect performance.

RADIATOR CAP COVER
Install the radiator cap cover using the two screws
which are taped to the radiator cap cover.
AIR CLEANER INLET HOOD
Remove the plastic plug covering the air cleaner inlet.
Install the air cleaner inlet hood to the air cleaner.
HIGH FREQUENCY GENERATORS
FOR TIG APPLICATIONS
The K799 Hi-Freq Unit and the K930-1 or -2 TIG
Module are suitable for use with the COMMANDER
500 CUMMINS. The COMMANDER 500 CUMMINS is
equipped with the required R.F. bypass circuitry for the
connection of high frequency generating equipment.
The high frequency bypass network supplied with the
K799 Hi-Freq Unit does NOT need to be installed into
the COMMANDER 500 CUMMINS.
The COMMANDER 500 CUMMINS and any high fre-
quency generating equipment must be properly
grounded. See the K799 Hi-Freq Unit and the K930-1
or-2 TIG Module operating manuals for complete
instructions on installation, operation, and mainte-
nance.
REMOTE CONTROL
OUTPUT
The COMMANDER 500 CUMMINS is equipped with a
6-pin & 14-pin connector. The 6-pin connector is for
connecting the K857 or K857-1 Remote Control
(Optional) or in the case of TIG welding applications,
with the foot or hand Amptrol (K870 or K963-1 respec-
tively).
The 14-pin connector is used to directly connect a wire
feeder or TIG Module (K930-1 or -2) control cable.
NOTE: When using the 14-pin connector, if the wire
feeder has a built in power source output control, do
not connect anything to the 6-pin connector.
WELDING TERMINALS
The Commander is equipped with a toggle switch for
selecting "hot" welding terminals when in the "WELD
TERMINALS ON" position or "cold" welding terminals
when in the "REMOTELY CONTROLLED" position.
