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.

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 within the rating
of the machine. For information on electrodes and their proper
application see (www.lincolnelectric.com) or the appropriate
Lincoln publication.
The Vantage 322 / LE400 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 CONTROL dial adjusts the full
output range for stick welding.
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.

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) increases 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 connection of
the work clamp to the job. The work clamp should be connected
as close as practical to where the welding will be performed.
A. For New Electrodes
E6010 - Touch, Lift to Start the Arc
E7018, E7024 - Touch, Rock Back and Forth in Joint, Lift .
Once the arc is started, normal welding technique for the applica-
tion is then used.
B. For Re-Striking Electrodes
Some electrodes form a cone at the end of the electrode after the
welding arc has been broken, particularly iron powder and low
hydrogen electrodes. This cone will need to be broken off in order
to have the metal core of the electrode make contact.
E6010 - Push, Twist in Joint, Lift
E7018, E7024 - Push, Rock Back and Forth in Joint, Lift.
Once the arc is started, normal welding technique for the
application is then used.
For other electrodes the above techniques should be tried first and
varied as needed to suit operator preference. The goal for
successful starting is good metal to metal contact.
For indicator light operation, see Table B.1.
