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 AIR VANTAGE® 500 KUBOTA 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 (arc-
force) during stick welding to adjust for a soft or crisp arc.
Increasing the number from -10(soft) to +10(crisp) increas-
es the short circuit current and prevents sticking of the
electrode to the plate while welding. This can also increase
spatter. It is recommended that the ARC CONTROL be set
to the minimum number without electrode sticking. Start
with the dial set at 0.
NOTE: Due to the low OCV with the VRD on, a very
slight delay during striking of the electrodes may
occur. Due to the requirement of the resistance in the
circuit to be low for a VRD to operate, a good metal-
to-metal contact must be made between the metal
core of the electrode and the job. A poor connection
anywhere in the welding output circuit may limit the
operation of the VRD. This includes a good connec-
tion of the work clamp to the job. The work clamp
should be connected as close as practical to where
the welding will be performed.

NOTE: This data is for reference only. Fuel consumption is
approximate and can be influenced by many factors, including
engine maintenance, environmental conditions and fuel quality.
TYPICAL AIR VANTAGE® 500 KUbOTA FUEL CONSUMPTION
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.
