SAFETY INSTRUCTIONS

WARNING

Do not attempt to use this equipment until you have thoroughly read all operating and maintenance man- uals supplied with your machine. They include impor- tant 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 equip- ment.

ADDITIONAL SAFETY PRECAUTIONS

Always operate the welder with the hinged door closed and the side panels in place as these provide maxi- mum protection from moving parts and insure proper cooling air flow.

GENERAL DESCRIPTION

The Commander 500 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 Commander 500 is not recom- mended 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 Deutz F3L-912 engine is equipped with a stan- dard, heavy duty, combination fuel filter/water separa- tor element.

RECOMMENDED APPLICATIONS

WELDER

The Commander 500 provides excellent constant current DC welding output for stick (SMAW) and TIG welding. The Commander 500 also provides excellent constant voltage DC welding output for MIG (GMAW) and Innershield (FCAW) welding.

GENERATOR

The Commander 500 provides smooth 120/240 VAC output for auxiliary power and emergency standby power.
