Lincoln Electric IM10003 VANTAGE 500-I - Manual (Page 19)

WELDER OPERATION
DUTY CYCLE
Duty Cycle is the percentage of time the load is being
applied in a 10 minute period. For example a 60% duty
cycle, represents 6 minutes of load and 4 minutes of no
load in a 10 minute period.
ELECTRODE INFORMATION
For any electrode the procedures should be kept with-
in the rating of the machine. For information on elec-
trodes and their proper application see (www.lincoln-
electric.com) or the appropriate Lincoln publication.
The VANTAGE® 500-I can be used with a broad range
of DC stick electrodes. The MODE switch provides two
stick welding settings as follows:
CONSTANT CURRENT (CC-STICK) WELDING
The CC-STICK position of the MODE switch is designed
for horizontal and vertical-up welding with all types of
electrodes, especially low hydrogen. The OUTPUT CON-
TROL dial adjusts the full output range for stick welding.
The ARC CONTROL dial sets the short circuit current
NOTE: If the unit fails to start turn Run/Stop switch
to off and repeat step 3 through step 7 after
waiting 30 seconds.
• Do not allow the starter motor to run continuously
for more than 20 seconds.
• Do not push the START button while the engine
is running because this can damage the ring
gear and/or the starter motor.
• IF the Engine Protection or battery Charging
Lights do “not” turn off shortly after starting the
engine shut off the engine immediately and
determine the cause.
------------------------------------------------------------------------
NOTE: When starting for the first time, or after and
extended period of time of not operating, it will take
longer than normal to start because the fuel pump
has to fill the fuel system. For best results, bleed the
fuel system as indicated in Maintenance Section of
this manual.
STOPPING THE ENGINE
Remove all welding and auxiliary power loads and
allow the engine to run at low idle speed for a few
minutes to cool the engine.
STOP the engine by placing the RUN-STOP switch in
the STOP position.
NOTE: A fuel shut off valve is located on the fuel pre-
filter.

14. ENGINE HOUR METER- Displays the total time
that the engine has been running. This meter is useful
for scheduling prescribed maintenance.
15. ENGINE PROTECTION LIGHT- A warning indi-
cator light for Low Oil Pressure and/or Coolant Over
Temperature.The light is off when the systems are func-
tioning properly. The light will come on and the engine
will shutdown when there is Low Oil Pressure and/or
the Coolant is Over Temperature.
Note: The light remains off when the RUN-STOP switch
is in the "ON" position prior to starting the engine.
However if the engine is not started within 60 seconds
the light will come on. When this happens the RUN-
STOP switch must be returned to the "OFF" position to
reset the engine protection system and light.
16. bATTERY CHARGING LIGHT- A warning
indicator light for Low/No battery charge. The light is off
when the systems are functioning properly. The light
will come on if there is a Low/No battery condition but
the machine will continue to run.
Note:
The light may or may not come on when the RUN-
STOP switch is in the "ON" position. It will come on dur-
ing cranking and stay on until the engine starts. After
starting the engine the light will go off unless a Low/No
battery charge condition exists.
17. COOLANT TEMPERATURE GAUGE- A indica-
tor of engine coolant temperature.
18. OIL PRESSURE GAUGE- A indicator of engine
Oil Pressure.
19. CIRCUIT bREAKER- For protection of Battery
Charging Circuit.
STARTING THE ENGINE
1. Remove all plugs connected to the AC power recepta-
cles.
2. Set IDLER switch to AUTO.
3. Press Glow Plug Button and hold 15 to 20 seconds.
4. Set the RUN/STOP switch to RUN.
5. Press START button until the engine starts or for up to
10 seconds. Continue to hold the glow plug button for up
to an additional 10 seconds.
6. Release the engine START button immediately when the
engine starts.
7. The engine will run at high idle speed for approximately
12 seconds and then drop to low idle speed. Allow the
engine to warm up at low idle for several minutes before
applying a load and/or switching to high idle. Allow a
longer warm up time in cold weather.
