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 within the rat-
ing of the machine. For information on electrodes and their prop-
er application see (www.lincolnelectric.com) or the appropriate
Lincoln publication.
The VANTAGE
®
400-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 CONTROL dial adjusts the full output range
for stick welding.
The ARC CONTROL dial sets the short circuit current (arc-force) dur-
ing stick welding to adjust for a soft or crisp arc. Increasing the
number from -10(soft) to +10(crisp) increases the short circuit cur-
rent and prevents sticking of the electrode to the plate while weld-
ing. 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 require-
ment of the resistance in the circuit to be low for a VRD to oper-
ate, 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 con-
nected as close as practical to where the welding will be per-
formed.
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 appli-
cation 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.
