IMPORTANT: To prevent ELECTRICAL DAMAGE
WHEN:

a) Installing new batteries

b) Using a booster

Use correct polarity — Negative Ground.

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 the negative battery
cable terminal.

NOTE: This machine is furnished with a wet charged
battery; if unused for several months, the battery 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
to the outlet tube with the pipe positioned to direct the
exhaust in the desired direction.

SPARK ARRESTER

Some federal, state or local laws may require that
gasoline or diesel engines be equipped with exhaust
spark arresters 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 arrester. When required by
local regulations, a suitable spark arrester must be
installed and properly maintained.

An incorrect arrester may lead to damage to the engine
or adversely affect performance.

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.
The Commander 500 is equipped with the required
R.F. bypass circuitry for the connection of high fre-
quency generating equipment. The high frequency
bypass network supplied with the K799 Hi-Freq Unit
does NOT need to be installed into the Commander
500.

The Commander 500 and any high frequency generat-
ing 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 instal-
lation, operation, and maintenance.

ELECTRICAL CONNECTIONS

REMOTE CONTROL

The Commander 500 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 (optional) or, in the
case of TIG welding applications, with the foot or hand
Amptrol (K870 or K963-1 respectively).

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 "WELDING TERMINALS REMOTELY
CONTROLLED" position.
