preset wire speed at idle. When the unit is in
a welding state, actual wire speed is displayed
for the active welding sequence.

Wire Speed LED
5
Amps LED
The LEDs below the display illuminate to indi-
cate which value is being shown.
•
If the unit is in a welding state that does not
involve feeding wire, the unit displays the
weld sequence wire speed. At any time dur-
ing welding, the weld sequence wire speed
can be adjusted and overrides the preset
wire speed display. In other words, if the Ad-
just control is activated while welding, the
unit displays and permits adjustment of the
weld sequence wire feed speed regardless
of the active welding sequence.
•
When the unit is displaying amperage, the
Amps LED illuminates. Amperage is only
displayed if the unit is in a welding state and
the amperage is above a minimum value of
25 Amps.
•
The display will read dashes for amperage
readings below the amperage threshold,
prior to arc initiation.

Dual Schedule LED
•
When the Setup button is pressed, the Set-
up push button LED flashes and the Trigger
Hold LED flashes.
•
The flashing LED indicates that the unit is in
the trigger hold display mode. In this mode
the upper display indicates HOLD and the
lower display indicates the trigger hold sta-
tus On/Off. Use the Adjust control to change
the trigger hold status or press the lower dis-
play push button. If trigger hold is turned On,
the trigger hold LED illuminates and stays
On.
•
When trigger hold is On, the user must
press and hold the trigger for a predefined
amount of time (the trigger hold delay time
−
see Section 6-10), then release it for the trig-
ger hold function to be active. To shut off the
weld when trigger hold is On, the user must
press and release the trigger.
•
If a weld time is programmed, trigger hold is
disabled.
•
Trigger hold and dual schedule cannot be
used concurrently.
•
When the Setup button is pressed a second
time, the dual schedule LED flashes. In this
mode the upper display indicates DUAL and
the lower display indicates dual schedule
status On/Off. Use the Adjust control to
change the dual schedule status if desired.
•
Pressing the Setup button again exits the
Setup mode. The dual schedule LED stops
flashing to indicate the dual schedule status
is Off.
•
While in the Setup mode, the active program
can be adjusted without deactivating the
trigger hold Setup mode operation. If the
trigger is activated, Setup mode(s) is termi-
nated.
