MUFFLER

Remove the plastic plug covering the muffler outlet
tube. Using the clamp provided secure the extension to
the outlet tube. This welder is supplied with an
adjustable rain cap for the muffler. Install the rain cap
using the clamp provided with the outlet facing away
from the direction in which this unit will be transported.
This will minimize the amount of water and debris
which could enter the muffler during transportation.

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, such as the
S24647 must be installed and properly maintained.
CAUTION
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 300.
The Commander 300 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
300.
The Commander 300 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.
INSTALLATION

REMOTE CONTROL

OUTPUT
The Commander 300 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 K812 respectively).
The 14 pin connector is used to directly connect a wire
feeder or TIG Module (K930-1 or-2) control cable.
When remote output control is used, the output control
toggle switch is to be set at "Remote."
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-
ING TERMINALS ALWAYS ON" position
welding terminals when in the "WELDING TERMI-
NALS REMOTELY CONTROLLED" position.
