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 above "VRD
Indicator Lights"
DOWNHILL PIPE Welding
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 dial adjusts the full output
range for pipe welding.
The ARC CONTROL dial sets the short circuit current
(arc-force) during stick welding to adjust for a soft or
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 deposition
("stacking" of iron) are key to fast travel speeds. This
can also increade spatter.
It is recommended that the ARC CONTROL be set to the
minimum number without electrode sticking. For
indicator light operation, see table above.
NOTE:
With the VRD switch in the “ON” position there is
no output in the DOWNHILL PIPE mode. For indicator
light operation, see table above. "VRD Indicator Lights".
TIG WELDING
The TOUCH START TIG setting of the MODE switch is
for DC TIG (Tungsten Inert Gas) welding. To initiate a
weld, the OUTPUT CONTROL dial 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, no
tungsten contamination. Then, the tungsten is gently
lifted off the work in a rocking motion, which establishes
the arc.
When in the TOUCH START TIG mode and when an
Amptrol is connected to the 6-pin Connector the
OUTPUT dial is used to set the maximum current range
of the CURRENT CONTROL of the Amptrol.
The ARC CONTROL is not active in the TIG mode. To
STOP a weld, simply pull the TIG torch away from the
work. When the arc voltage reaches approximately 30 V
the arc will go out and the machine will reset the current
to the TOUCH START level.
To reinitiate the arc, retouch the tungsten to the work
and lift. Alternatively, the weld can be stopped by
releasing the Amptrol or arc start switch.
The Vantage
®
410 CE can be used in a wide variety of
DC TIG welding applications. In general the “Touch
Start” feature allows contamination free starting without
the use of a Hi frequency unit. If desired, the K930-2
TIG Module can be used with the Vantage. The settings
are for reference, in the table below.
Vantage
®
410 CE settings when using the K930-2 TIG
Module with an Amptrol or Arc Start Switch:
Set the MODE Switch to the TOUCH START TIG
setting.
Set the "IDLER" Switch to the "AUTO" position.
Set the "WELDING TERMINALS" switch to the
"REMOTELY CONTROLLED" position. This will
keep the "Solid State" contactor open and provide a
“cold” electrode until the Amptrol or Arc Start Switch
is pressed.
When using the TIG Module, the OUTPUT CONTROL
on the Vantage
®
410 CE is used to set the maximum
range of the CURRENT CONTROL on the TIG Module
oe an Amptrol if connected to the TIG Module.
