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.

STICK WELDING MODE

®
The VANTAGE 600 SD can be used with a broad range of DC stick
electrodes.
The MODE switch provides two stick welding settings as follows:

CC-STICK MODE

The CC-STICK position of the MODE switch is designed for horizontal, ver-
tical-up and over head welding with all types of electrodes, especially low
hydrogen. The OUTPUT CONTROL knob adjusts the full output range for
stick welding.
The ARC CONTROL knob sets the short circuit (arc-force) current during
stick welding. 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 recom-
mended that the ARC CONTROL be set to the minimum number without
electrode sticking. Start with the knob set at 0.
DOWNHILL PIPE MODE
This slope controlled setting is intended for "out-of-position" and "down
hill" pipe welding where the operator would like to control the current
level by changing the arc length. The OUTPUT CONTROL knob adjusts the
full output range for pipe welding.
The ARC CONTROL knob sets the short circuit current (arc-force) during
stick welding to adjust for a soft or a more forceful digging arc (Crisp).
Increasing the number from -10(Soft) to +10(Crisp) increases the short
circuit current which results in a more forceful digging arc. Typically a
forceful digging arc is preferred for root and hot passes. A softer arc is
preferred for fill and cap passes where weld puddle control and deposi-
tion ("stacking" of iron) are key to fast travel speeds. It is recommended
that the ARC CONTROL be set initially at 0.

TOUCH START TIG MODE
The VANTAGE
ing applications.
The TOUCH START TIG setting of the MODE switch is for DC TIG (Tungsten
Inert Gas) welding. To initiate a weld, the OUTPUT CONTROL knob is first
set to the desired current and the tungsten is touched to the work. During
the time the tungsten is touching the work there is very little voltage or
current and, in general, avoids tungsten contamination. Then, the tung-
sten is gently lifted off the work in a rocking motion, which establishes
the arc.
To stop the arc, simply lift the TIG torch away from the work piece. When
the arc voltage reaches approximately 30 volts, the arc will go out and the
machine will automatically reset to the touch start current level. The
tungsten may then be retouched to the work piece to restrike the arc. The
arc may also be started and stopped with an Amptrol or Arc Start Switch.
The ARC CONTROL is not active in the TIG mode.
In general the 'Touch Start' feature avoids tungsten contamination with-
out the use of a Hi-frequency unit. If the use of a high frequency genera-
tor is desired, the K930-2 TIG Module can be used with the
VANTAGE
The VANTAGE
cuitry for the connection of high frequency generating equipment.
The VANTAGE
ment must be properly grounded. See the K930-2 TIG Module
operating manuals for complete instructions on installation, opera-
tion, and maintenance.
When using the TIG Module, the OUTPUT control on the
VANTAGE
RENT CONTROL on the TIG Module Amptrol.
