Set up parameters are selected with the SELECT switch,
an up/down center-off momentary toggle switch. Moving
the switch bat up or down moves an LED in the
corresponding direction. Holding the switch in either
direction will cause the indicator to move quickly in the
corresponding direction until the switch is released, or
the upper or lower limit is reached.
The value of the active set up parameter is shown on the
panel digital display. The value can be modified with the
SET switch. The SET switch is an up/down center-off
momentary toggle switch. Moving the switch bat up or
down adjusts the displayed value in the corresponding
direction. Holding the switch in either direction will
cause the display to move quickly in the corresponding
direction until the switch is released, or the upper or
lower parameter limit is reached.
Weld Mode
The Weld Mode selection can be enabled by toggling the
SELECT switch until the LED next to WELD MODE is lit.
The present mode number will be displayed.
Positioning the SET switch up or down will increase or
decrease to the next WELD MODE number and display
it. The machine will change to the selected weld mode
after two seconds of SET switch inactivity. If the
SELECT switch is changed before two seconds of SET
switch inactivity, the machine will not change modes.
The last active Weld Mode will be saved at power down
so that it will be selected upon the next power up of the
machine.
Preflow / Postflow
• The Preflow setting allows a time to be selected for
shielding gas to flow after the trigger is pulled and
prior to wire feeding and arc strike.
•
The Postflow setting allows a time to be selected for
shielding gas to continue to flow after the trigger is
released and output current is turned off.
•
The Preflow timer will be selected by toggling the
SELECT switch until the LED next to PREFLOW /
POSTFLOW is lit. The Display Meters will read PrE
FLo. The present Preflow time will be displayed
and can be changed by positioning the SET switch
up or down.
• The Postflow timer will be selected by toggling the
SELECT switch and additional time. The LED next
to PREFLOW / POSTFLOW will remain lit; but the
Display Meters will now read PoS FLo. The present
Postflow time will be displayed and can be changed
by positioning the SET switch up or down.
•
The default value for both Preflow and Postflow is
"OFF" (0 seconds).
• Preflow can be adjusted from 0 to 2.5 seconds in
0.1 second increments.
•
Postflow can be adjusted from 0 to 10.0 seconds in
0.1 second increments.
Run-In
•
The Run-In function offers the ability to set a wire
feed speed, from trigger until an arc is established,
that is independent of the Welding or Start wire feed
speed.
•
Run-In will be selected by toggling the SELECT
switch until the LED next to RUN-IN is lit. A Run-In
WFS may be adjusted using the SET switch on the
Multi-Process Panel. The Display meter on the
Multi-Process Panel will indicate the run-in speed.
Do not use the Output Control Knob on the
uppercase front to adjust the WFS. This will change
the welding WFS displayed in the meters on the
upper case front.
•
The default value is "OFF".
• Run-In speed is adjustable from 1.27m/min to
3.81m/min.
Start
• The Start function offers the ability to set a wire feed
speed and voltage at the beginning of a weld for a
specified time period of the weld prior to initiation of
the preset values for WFS and Volts. At arc strike,
the start timer will begin and the WFS and Volts
settings will ramp up/down from the start values to
the Weld Mode WFS and Voltage settings over the
time selected. This creates a ramping of the WFS
and Volts during the Start time.
• The Start function will be selected by toggling the
SELECT switch until the LED next to START is lit
and flashing. A start time may be adjusted using
the SET switch.
• The default value is "OFF" (0 seconds).
•
Start time is adjustable from 0 to 0.50 seconds in
.01 second increments.
•
In the GMAW, FCAW, and Power weld modes, start
wfs and voltage are adjustable using the control
knobs on the upper case front. This is indicated by
the flashing LEDs next to "WFS" and "VOLTS".
•
In the GMAW-P weld modes, a start wire feed
speed and trim are adjustable. This is indicated by
the flashing LEDs next to "WFS" and "TRIM".
Arc Control
• In the CV modes, the Arc Control regulates pinch
effect. At the minimum setting, pinch is minimized
which results in a soft arc. Low pinch settings are
preferable for welding with gas mixes containing
mostly inert gases. At the maximum setting, pinch
is maximized which results in a crisp arc. High
pinch settings are preferable for welding FCAW and
GMAW with CO2. Most self-shielded wires work
well at an Arc Control setting of 5.
• In the Pulse Mode, the Arc control regulates the
frequency of the pulse.
•
In the Pulse & Pulse Mode, the Arc Control
regulates the frequency of oscillations between high
and low level of amperage.
•
In the CC-Stick modes, the Arc Control regulates
the Arc Force to adjust the short circuit current. The
minimum setting will produce a soft arc and will
result in minimal spatter. The maximum setting will
produce a crisp arc and will minimize electrode
sticking.
•
The Arc-control adjustment will be selected by
toggling the SELECT switch until the LED next to
ARC CONTROL is lit. The Arc-control value will be
displayed. Arc-control can be adjusted by
positioning the SET switch up or down.
• The default value is "OFF".
•
The value is adjustable from –10.0 to 10.0 in 0.1
increments.
Crater
•
The Crater function offers the ability to set an
endpoint for WFS and Voltage that will be reached
over a specified time period. At the end of the weld
when the trigger is released, the crater timer will
begin and the WFS and Volts settings will ramp
