GENERAL DESCRIPTION

The Commander 300 is a diesel engine-driven welding
power source. The machine uses a brush type alter-
nating current generator for DC multi-purpose welding
and for 120/240 VAC auxiliary standby power. The
welding control system uses state of the art Chopper
Technology.

The generator has a single sealed bearing for mainte-
nance-free service. The rotor is a copper wound
design with two slip rings and brushes. The stator is
wound entirely with heavy gauge copper wire and insu-
lated with NEMA class F insulation material. The sta-
tor is then impregnated with three layers of high quali-
ty varnish. After the stator is assembled using tie bars,
the entire assembly is covered with an environmental-
ly protective coating. These measures insure trouble-
free operation in the harshest environments.

The fuel tank is made from high density polyethylene
and holds 25 gallons (94.6 liters) of diesel fuel. This
will provide enough fuel to run for 18 hours at full load.

The Deutz F3L-1011 F engine is equipped with a stan-
dard, heavy duty, combination fuel filter/water separa-
tor element.

RECOMMENDED APPLICATIONS

WELDER

The Commander 300 (Stick model) provides excellent
constant current DC welding output for stick (SMAW)
welding. The Commander 300 (Stick & Wire model)
also provides excellent constant voltage DC welding
output for MIG (GMAW) and Innershield (FCAW)
welding.

GENERATOR

The Commander 300 provides smooth 120/240 VAC
output for auxiliary power and emergency standby
power.

DESIGN FEATURES

K1585-2 Commander 300 Deluxe Model Features

FOR WELDING:

• Excellent DC multi-purpose welding for stick, MIG,

TIG, cored wire and arc gouging applications.

• 30 to 300 amps output in five slope controlled ranges

for out-of position and pipe electrodes, one constant
current output range for general purpose welding,
and one constant voltage range for MIG wire and
cored wire welding.

• 100% duty cycle at 300 amps output and 60 % duty

cycle at 375 amps output.

• Dual 3-digit output meters are provided (optional on

K1585-1) for presetting the weld amperage or volt-
age and displaying the actual amperage and voltage
during welding. The meters use superbrite LEDs for
improved readability in full sunlight.

• Standard remote control capability with 14-pin and 6-

pin connectors for easy connection of Lincoln remote
control accessories.

• An internal “Solid State” contactor allows for the

selection of “hot” or “cold” output terminals with a
toggle switch on the control panel.

• ”Arc Control” potentiometer in Wire and Stick modes

for precise adjustment of arc characteristics.

• Advanced circuitry to prevent pop-outs in the five

slope modes.

FOR AUXILIARY POWER

• 10,000 watts of 120/240 VAC, 60Hz auxiliary power.

• Power for tools, 120/240 VAC lights, electric pumps

and for standby emergency power.

• Power to drive a 2 HP motor (provided it is started

under no load).

• Two 15 amp 120 VAC duplex receptacles with GFCI

protection for up to 30 amps of 120 VAC power.

• One 50 amp, 120/240 VAC dual voltage receptacle

for up to 44 amps of 240 VAC and up to 44 amps per
side to separate branch circuits (not in parallel) of
120 VAC single phase auxiliary power. Allows easy
connection to premises wiring.

• Weld and provide AC auxiliary power at the same

time (within machine total capacity).
