SAFETY INSTRUCTIONS
Read and understand this entire section before operat-
ing your COMMANDER 500 CUMMINS.
Do not attempt to use this equipment until you
have thoroughly read all operating and mainte-
nance manuals supplied with your machine. They
include important safety precautions, detailed
engine starting, operating and maintenance
instructions and parts lists.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
such as output terminals or internal
wiring.
• Insulate yourself from the work and
ground.
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside
• Do not stack anything near the
engine.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts
------------------------------------------------------------------------
Only qualified personnel should operate this
equipment.
ADDITIONAL SAFETY PRECAUTIONS
Always operate the welder with the hinged door
closed and the side panels in place as these pro-
vide maximum protection from moving parts and
insure proper cooling air flow.
GENERAL DESCRIPTION
The COMMANDER 500 CUMMINS is a diesel engine-
driven welding power source. The machine uses a
brush type alternating current generator for DC multi-
purpose welding and for 120/240 VAC auxiliary stand-
by power. The welding control system uses state of the
art
Chopper Technology. The COMMANDER 500
CUMMINS is not recommended for pipe thawing.
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 insulated
with NEMA class F insulation material. The stator is
then impregnated with three layers of high quality var-
nish. After the stator is assembled using tie bars, the
entire assembly covered with an environmentally pro-
tective coating. These measures insure trouble-free
operation in the harshest environments.
The fuel tank is made from high density polyethylene
and holds 25 gallons of diesel fuel. This will provide
enough fuel to run for more than 12 hours at full load.
The Cummins B3.3 engine is equipped with a stan-
dard, heavy duty, combination fuel filter/water separa-
tor element.
RECOMMENDED APPLICATIONS
WELDER
The COMMANDER 500 CUMMINS provides excellent con-
stant current DC welding output for stick (SMAW) and TIG
welding. The COMMANDER 500 CUMMINS also provides
excellent constant voltage DC welding output for MIG
(GMAW) and Innershield (FCAW) welding.
GENERATOR
The COMMANDER 500 CUMMINS provides smooth
120/240 VAC output for auxiliary power and emergency
standby power.
