SAFETY PRECAUTIONS
WARNING
Do not attempt to use this equipment until you have
thoroughly read the engine manufacturer's manual
supplied with your welder. It includes important safety
precautions, detailed engine starting, operating and
maintenance instructions, and parts lists.
ELECTRIC SHOCK can kill.
•
Do not touch electrically live parts or
electrode with skin or wet clothing.
•
Insulate yourself from work and ground
•
Always wear dry insulating gloves.
•
Always operate the welder with the hinged door closed
and the side panels in place.
•
Read carefully the Safety Precautions page before
operating this machine. Always follow these and any
other safety procedures included in this manual and in
the Engine Instruction Manual.
GENERAL dESCRIPTION
The Fleet™ 400 is a diesel engine powered DC multi-process
welding power source and AC power generator. The engine drives
a generator that supplies three phase power for the DC welding
circuit, single phase power for the AC auxiliary outlets. The DC
welding control system uses state of the art Chopper Technology
for superior welding performance.
For Auxiliary Power:
Start the engine and set the Weld Mode Selector switch to the
desired operating mode. Full power is available regardless of the
welding control settings providing no welding current is being
drawn.
ENGINE OPERATION
Before Starting the Engine:
•
Be sure the machine is on a level surface.
•
Open side engine door and remove the engine oil dipstick and
wipe it with a clean cloth. Reinsert the dipstick and check the
level on the dipstick.
•
Add oil (if necessary) to bring the level up to the full mark. Do
not overfill. Close engine door.
•
See Engine Owner's Manual for specific oil recommendations.
Add FUEL
WARNING
DIESEL FUEL can cause fire.
•
Stop engine while fueling.
•
Do not smoke when fueling.
•
Keep sparks and flame away from tank.
•
Do not leave unattended while fueling.
•
Wipe up spilled fuel and allow fumes to clear before
starting engine.
•
Do not overfill tank, fuel expansion may cause overflow.
Diesel Fuel Only-Low Sulphur Fuel or Ultra Low Sulphur
in USA and Canada.
•
Remove the fuel tank cap.
Fill the tank. DO NOT FILL THE TANK TO THE POINT OF
•
OVERFLOW.
•
Replace the fuel cap and tighten securely.
•
See Engine Owner's Manual for specific fuel recommendations.
BREAK-IN PERIOd
Lincoln Electric selects high quality, heavy-duty industrial engines
for the portable welding machines we offer. While it is normal to
see a small amount of crankcase oil consumption during initial
operation, excessive oil use, wetstacking (oil or tar like substance
at the exhaust port), or excessive smoke is not normal.
Larger machines with a capacity of 350 amperes and higher,
which are operated at low or no-load conditions for extended
periods of time are especially susceptible to the conditions
described above. To accomplish successful engine break-in, most
diesel-powered equipment needs only to be run at a reasonably
heavy load within the rating of the welder for some period of time
during the engine's early life. However, if the welder is subjected
to extensive light loading, occasional moderate to heavy loading of
the engine may sometimes be necessary. Caution must be
observed in correctly loading a diesel/generator unit.
1. Connect the welder output studs to a suitable resistive load bank.
Note that any attempt to short the output studs by connecting the
welding leads together, direct shorting of the output studs, or
connecting the output leads to a length of steel will result in
catastrophic damage to the generator and voids the warranty.
2. Set the welder controls for an output current and voltage within
the welder rating and duty cycle. Note that any attempt to
exceed the welder rating or duty cycle for any period of time will
result in catastrophic damage to the generator and voids the
warranty.
3. Periodically shut off the engine and check the crankcase oil level.
CAUTION
During break-in, subject the Welder to moderate loads.
Avoid long periods running at idle. Before stopping the
engine, remove all loads and allow the engine to cool
several minutes.
